LORD LEGGATT: (with whom Lord Reed, Lord Hodge, Lady Arden, Lord
Sales and Lord Hamblen agree)
Introduction

  1. New ways of working organised through digital platforms pose pressing
    questions about the employment status of the people who do the work involved. The
    central question on this appeal is whether an employment tribunal was entitled to
    find that drivers whose work is arranged through Uber’s smartphone application
    (“the Uber app”) work for Uber under workers’ contracts and so qualify for the
    national minimum wage, paid annual leave and other workers’ rights; or whether, as
    Uber contends, the drivers do not have these rights because they work for themselves
    as independent contractors, performing services under contracts made with
    passengers through Uber as their booking agent. If drivers work for Uber under
    workers’ contracts, a secondary question arises as to whether the employment
    tribunal was also entitled to find that the drivers who have brought the present claims
    were working under such contracts whenever they were logged into the Uber app
    within the territory in which they were licensed to operate and ready and willing to
    accept trips; or whether, as Uber argues, they were working only when driving
    passengers to their destinations.
  2. For the reasons given in this judgment, I would affirm the conclusion of the
    Employment Appeal Tribunal and the majority of the Court of Appeal that the
    employment tribunal was entitled to decide both questions in the claimants’ favour.
    The parties
  3. The first appellant, Uber BV, is a Dutch company which owns the rights in
    the Uber app. The second appellant, Uber London Ltd (“Uber London”), is a UK
    subsidiary of Uber BV which, since May 2012, has been licensed to operate private
    hire vehicles in London. The third appellant, Uber Britannia Ltd, is another UK
    subsidiary of Uber BV which holds licences to operate such vehicles outside
    London. In this judgment I will use the name “Uber” to refer to the appellants
    collectively when it is not necessary to differentiate between them.
  4. The claimants, and respondents to this appeal, are individuals who work or
    used to work as private hire vehicle drivers, performing driving services booked
    through the Uber app. For the purpose of the decision which has given rise to this
    appeal, the employment tribunal limited its consideration to two test claimants, Mr
    Page 3
    Yaseen Aslam and Mr James Farrar, both of whom were licensed to drive private
    hire vehicles in London. Like the employment tribunal, I will use masculine
    pronouns for brevity when referring to Uber drivers in this judgment in
    circumstances where all the claimant drivers are male.
  5. At the time of the employment tribunal hearing in 2016, there were about
    30,000 Uber drivers operating in the London area and 40,000 in the UK as a whole.
    Some two million people were registered to use the Uber app as passengers in
    London.
    The Uber system
  6. As described in more detail in the decision of the employment tribunal,
    Uber’s business model is simple. Prospective customers download the Uber app (for
    free) to their smartphone and create an account by providing personal information
    including a method of payment. They are then able to request rides. To do so, they
    open the Uber app on their phone and make a request. In the period considered by
    the employment tribunal, users did not have to enter their destination when booking
    a ride through the app, but they generally did so. The Uber app identifies the
    passenger’s location through the smartphone’s geolocation system. Using the same
    technology, the app identifies the nearest available driver who is logged into the app
    and informs him (via his smartphone) of the request. At this stage the driver is told
    the passenger’s first name and Uber rating (as to which, see below) and has ten
    seconds in which to decide whether to accept the request. If the driver does not
    respond within that time, the next closest driver is located and offered the trip. Once
    a driver accepts, the trip is assigned to that driver and the booking confirmed to the
    passenger, who is sent the driver’s name and car details.
  7. At this point the driver and passenger are put into direct contact with each
    other through the Uber app, but this is done in such a way that neither has access to
    the other’s mobile telephone number. The purpose is to enable them to communicate
    with each other in relation to the pick-up, for example to identify the passenger’s
    precise location or to advise of problems such as traffic delay. The passenger can
    also track the driver’s progress on a map on their smartphone.
  8. The driver is not informed of the passenger’s destination until the passenger
    is collected. At that point the driver learns the destination either directly from the
    passenger or through the app (if the destination was entered when the ride was
    requested) when the driver presses “start trip” on his phone. The Uber app
    incorporates route planning software and provides the driver with detailed directions
    to the destination. The driver is not bound to follow those directions but departure
    Page 4
    from the recommended route may result in a reduction in payment if the passenger
    complains about the route taken.
  9. On arrival at the destination, the driver presses “complete trip” on his
    smartphone. The fare is then calculated automatically by the Uber app, based on
    time spent and distance covered. At times and places of high demand, a multiplier
    is applied resulting in a higher fare. Drivers are permitted to accept payment in a
    lower, but not a higher, sum than the fare calculated by the app (although, in the
    unlikely event that a driver accepts a lower sum, the “service fee” retained by Uber
    BV is still based on the fare calculated by the app). Drivers are at liberty to accept
    tips but are discouraged by Uber from soliciting them.
  10. The fare is debited to the passenger’s credit or debit card registered on the
    Uber app and the passenger is sent a receipt for the payment by email. Separately,
    the Uber app generates a document described as an “invoice” addressed on behalf
    of the driver to the passenger (showing the passenger’s first name but not their
    surname or contact details). However, the passenger never sees this document,
    which is not sent to the passenger but is accessible to the driver on the Uber app and
    serves as a record of the trip and the fare charged.
  11. Uber BV makes a weekly payment to the driver of sums paid by passengers
    for trips driven by the driver less a “service fee” retained by Uber BV. In the cases
    of Mr Aslam and Mr Farrar, the service fee was 20% of the fares.
  12. Drivers are prohibited by Uber from exchanging contact details with a
    passenger or contacting a passenger after the trip ends other than to return lost
    property.
  13. Uber operates a ratings system whereby, after the trip, the passenger and
    driver are each sent a message asking them to rate the other anonymously on a scale
    of 1 to 5.
    Working as a driver
  14. To become an Uber driver, a person can sign up online. They must then attend
    and present certain documents at the offices of the local Uber company (which, for
    the London area, is Uber London). The required documents comprise a national
    insurance certificate, driving licence, licence to drive a private hire vehicle, vehicle
    logbook, MOT certificate and certificate of motor insurance. The applicant must
    also take part in what the employment tribunal described as “an interview, albeit not
    Page 5
    a searching one”, and watch a video presentation about the Uber app and certain
    Uber procedures. This process is referred to by Uber as “onboarding”.
  15. Individuals accepted as drivers are given free access to the Uber app through
    their own smartphone or may hire a smartphone for ÂŁ5 a month from Uber BV
    configured so that it can only be used to operate the Uber app. The driver has to
    provide and pay for his own vehicle, which must be on a list of accepted makes and
    models, in good condition, no older than a specified age and preferably silver or
    black. Drivers must also bear all the costs of running their vehicles, including fuel,
    insurance, road tax and the cost of obtaining a private hire vehicle licence.
  16. Individuals approved to work as drivers are free to make themselves available
    for work, by logging onto the Uber app, as much or as little as they want and at times
    of their own choosing. They are not prohibited from providing services for or
    through other organisations, including any direct competitor of Uber operating
    through another digital platform. Drivers can also choose where within the territory
    covered by their private hire vehicle licence they make themselves available for
    work. They are not provided with any insignia or uniform and in London are
    discouraged from displaying Uber branding of any kind on their vehicle.
  17. The employment tribunal made a number of findings about standards of
    performance which drivers are expected to meet and actions taken where drivers fail
    to meet these standards. For example, the tribunal found that a “Welcome Packet”
    of material issued by Uber London to new drivers included numerous instructions
    as to how drivers should conduct themselves, such as “Polite and professional at all
    times”, “Avoid inappropriate topics of conversation” and “Do not contact the rider
    after the trip has ended”. Other material in the Welcome Packet, under the heading
    “What Uber looks for”, stated:
    “High Quality Service Stats: We continually look at your driver
    rating, client comments, and feedback provided to us.
    Maintaining a high rating overall helps keep a top tier service
    to riders.
    Low Cancellation Rate: when you accept a trip request you
    have made a commitment to the rider. Cancelling often or
    cancelling for unwillingness to drive to your clients leads to a
    poor experience.
    High Acceptance Rate: Going on duty means you are willing
    and able to accept trip requests. Rejecting too many requests
    Page 6
    leads to rider confusion about availability. You should be off
    duty if not able to take requests.”
  18. Taking these three metrics in reverse order, drivers whose acceptance rate for
    trip requests falls below a set level – which according to evidence before the tribunal
    was 80% – receive warning messages reminding the driver that being logged into
    the Uber app is an indication that the driver is willing and able to accept trip requests.
    If the driver’s acceptance rate does not improve, the warnings escalate and culminate
    in the driver being automatically logged off the Uber app for ten minutes if the driver
    declines three trips in a row. A similar system of warnings, culminating in a tenminute log-off “penalty”, applies to cancellations by drivers after a trip has been
    accepted. The driver’s ratings from passengers are also monitored and the
    employment tribunal found that drivers who have undertaken 200 trips or more and
    whose average rating is below 4.4 become subject to a graduated series of “quality
    interventions” aimed at assisting them to improve. If their ratings do not improve to
    an average of 4.4 or better, they are “removed from the platform” and their accounts
    “deactivated”.
  19. Uber also operates a “driver offence process” to address misconduct by
    drivers. This again involves a graduated series of measures, beginning with a
    “warning” message and potentially leading to “deactivation”.
  20. In addition, Uber London handles passenger complaints, including
    complaints about a driver, and decides whether to make any refund to the passenger
    (sometimes without even referring the matter to the driver concerned). Such a refund
    will generally result in a correspondingly reduced payment to the driver, though the
    tribunal found that on occasions, when Uber London considers it necessary or politic
    to make a refund but there is no proper ground for holding the driver to be at fault,
    Uber London will bear the cost of the refund itself.
  21. Uber will in some circumstances pay drivers the cost, or a contribution
    towards the cost, of cleaning vehicles soiled by passengers. The employment
    tribunal noted that it was not suggested that such payments were conditional upon
    Uber recovering this sum from the passenger.
    Written agreements between Uber BV and drivers
  22. Before using the Uber app as drivers for the first time, the claimants were
    required to sign a “partner registration form” stating that they agreed to be bound by
    and comply with terms and conditions described as “Partner Terms” dated 1 July
  23. In October 2015 a new “Services Agreement” was introduced to which drivers
    Page 7
    were required to signify their agreement electronically before they could again log
    into the Uber app and accept trip requests. The differences between the old and new
    terms are not material for present purposes and it is sufficient to refer to the new
    terms contained in the Services Agreement.
  24. The Services Agreement is formulated as a legal agreement between Uber
    BV and “an independent company in the business of providing transportation
    services”, referred to as “Customer”. It contains an undertaking by “Customer” to
    enter into a contract with each driver in the form of an accompanying “Driver
    Addendum”. This arrangement is inapposite for the vast majority of drivers who
    sign up as individuals and not on behalf of any “independent company” which in
    turn engages drivers.
  25. In the typical case where “Customer” is an individual driver, the nature of the
    relevant services and relationships as characterised by the Services Agreement is
    that Uber BV agrees to provide electronic services (referred to as the “Uber
    Services”) to the driver, which include access to the Uber app and payment services,
    and the driver agrees to provide transportation services to passengers (referred to as
    “Users”). The agreement states that Customer acknowledges and agrees that Uber
    BV does not provide transportation services and that, where Customer accepts a
    User’s request for transportation services made through the Uber app, Customer is
    responsible for providing those transportation services and, by doing so, “creates a
    legal and direct business relationship between Customer and the User, to which
    neither Uber [BV] nor any of its Affiliates in the Territory is a party” (see clause
    2.3).
  26. Clause 4.1 of the Services Agreement states that:
    “… Customer: (i) appoints Uber [BV] as Customer’s limited
    payment collection agent solely for the purpose of accepting
    the Fare … on behalf of the Customer via the payment
    processing functionality facilitated by the Uber Services; and
    (ii) agrees that payment made by User to Uber [BV] shall be
    considered the same as payment made directly by User to
    Customer.”
    Clause 4.1 also states that the “Fare” is determined by Uber BV but describes it as
    charged by Customer and as “a recommended amount” which Customer may choose
    to reduce (but not increase) without the agreement of Uber BV. The clause further
    provides that Uber BV agrees to remit to Customer on at least a weekly basis the
    fare less a “service fee”, calculated as a percentage of the fare.
    Page 8
  27. Clause 4.2 gives Uber BV the right to change the fare calculation at any time
    in its discretion “based upon local market factors”; and clause 4.3 provides that Uber
    BV and/or its Affiliates reserve the right to adjust the fare for a particular instance
    of transportation services (eg where the driver took an inefficient route) or to cancel
    the fare (eg in response to a User complaint).
    Written agreements between Uber and passengers
  28. In addition to the written agreements between drivers and Uber BV, Uber
    also relies in these proceedings on written terms and conditions (the “Rider Terms”)
    which passengers are required to accept before they can use the Uber app. The
    version of the Rider Terms current at the time of the tribunal hearing was last
    updated on 16 June 2016. These Rider Terms state that they constitute an agreement
    between the rider, Uber BV and the local Uber company operating in the relevant
    part of the UK. As mentioned, in the case of London, the relevant company is Uber
    London.
  29. Clause 2 of Part 1 of the Rider Terms states that, as set out in clause 3, “Uber
    UK” (a term defined to include Uber London) accepts private hire vehicle bookings
    (“PHV Bookings”) made using the Uber app. Clause 3 states:
    “Uber UK accepts PHV Bookings acting as disclosed agent for
    the Transportation Provider (as principal). Such acceptance by
    Uber UK as agent for the Transportation Provider gives rise to
    a contract for the provision to you of transportation services
    between you and the Transportation Provider (the
    ‘Transportation Contract’). For the avoidance of doubt: Uber
    UK does not itself provide transportation services, and is not a
    Transportation Provider. Uber UK acts as intermediary
    between you and the Transportation Provider. You
    acknowledge and agree that the provision to you of
    transportation services by the Transportation Provider is
    pursuant to the Transportation Contract and that Uber UK
    accepts your booking as agent for the Transportation Provider,
    but is not a party to that contract.”
  30. Under Part 2 of the Rider Terms, riders are granted a licence by Uber BV to
    use the Uber app, described in clause 2 as “a technology platform that enables users
    … to pre-book and schedule transportation, logistics, delivery, and/or vendor
    services with independent third party providers of such services, including
    independent third party transportation providers.”
    Page 9
    The licensing regime
  31. The operation of private hire vehicles in London is regulated by the Private
    Hire Vehicles (London) Act 1998 and regulations made under it. Under that Act a
    vehicle may only be used for private hire if both vehicle and driver are licensed by
    the licensing authority, which is Transport for London. A licence is also required to
    accept bookings (referred to in the Act as “private hire bookings”) for the hire of a
    private hire vehicle to carry one or more passengers. Thus, section 2(1) provides:
    “No person shall in London make provision for the invitation
    or acceptance of, or accept, private hire bookings unless he is
    the holder of a private hire vehicle operator’s licence for
    London …”
    Pursuant to section 2(2), a person who makes provision for the invitation or
    acceptance of private hire bookings, or accepts such a booking, without such a
    licence is guilty of a criminal offence.
  32. At all relevant times Uber London has held a private hire vehicle (“PHV”)
    operator’s licence for London. Section 4(2) of the Act places an obligation on the
    holder of such a licence to secure that:
    “any vehicle which is provided by him for carrying out a
    private hire booking accepted by him in London is –
    (a) a vehicle for which a London PHV licence is in
    force driven by a person holding a London PHV driver’s
    licence; …”
  33. Pursuant to regulation 9(3) of the Private Hire Vehicles (London) (Operators’
    Licences) Regulations 2000, as originally formulated, it was a condition of the grant
    of a London PHV operator’s licence that:
    “The operator shall, if required to do so by a person making a
    private hire booking:
    (a) agree the fare for the journey booked, or
    Page 10
    (b) provide an estimate of that fare.”
    With effect from 27 June 2016, this regulation was amended to add a requirement
    that any estimate of the fare must be accurate, in accordance with criteria specified
    by the licensing authority.
  34. The obligations of the operator under the Act and regulations also include
    keeping records of all bookings accepted and of all private hire vehicles and drivers
    available to the operator for carrying out bookings accepted by him.
    Statutory rights of “workers”
  35. The rights claimed by the claimants in these proceedings are: rights under the
    National Minimum Wage Act 1998 and associated regulations to be paid at least the
    national minimum wage for work done; rights under the Working Time Regulations
    1998 which include the right to receive paid annual leave; and in the case of two
    claimants, one of whom is Mr Aslam, a right under the Employment Rights Act
    1996 not to suffer detrimental treatment on the grounds of having made a protected
    disclosure (“whistleblowing”).
  36. All these rights are conferred by the legislation on “workers”. The term
    “worker” is defined by section 230(3) of the Employment Rights Act 1996 to mean:
    “an individual who has entered into or works under (or, where
    the employment has ceased, worked under) –
    (a) a contract of employment, or
    (b) any other contract, whether express or implied
    and (if it is express) whether oral or in writing, whereby
    the individual undertakes to do or perform personally
    any work or services for another party to the contract
    whose status is not by virtue of the contract that of a
    client or customer of any profession or business
    undertaking carried on by the individual;
    and any reference to a worker’s contract shall be construed
    accordingly.”
    Page 11
  37. A “contract of employment” is defined in section 230(2) of the Act to mean
    “a contract of service or apprenticeship, whether express or implied, and (if it is
    express) whether oral or in writing.” An “employee” means an individual who has
    entered into or works under a contract of employment: see section 230(1). However,
    the terms “employer” and “employed” are defined more broadly to refer to the
    person by whom an employee or worker is (or was) employed under a worker’s
    contract: see section 230(4) and (5).
  38. Similar definitions of all these terms are contained in section 54 of the
    National Minimum Wage Act 1998 and regulation 2(1) of the Working Time
    Regulations 1998.
  39. The effect of these definitions, as Baroness Hale of Richmond observed in
    Bates van Winkelhof v Clyde & Co LLP [2014] UKSC 32; [2014] 1 WLR 2047,
    paras 25 and 31, is that employment law distinguishes between three types of people:
    those employed under a contract of employment; those self-employed people who
    are in business on their own account and undertake work for their clients or
    customers; and an intermediate class of workers who are self-employed but who
    provide their services as part of a profession or business undertaking carried on by
    someone else. Some statutory rights, such as the right not to be unfairly dismissed,
    are limited to those employed under a contract of employment; but other rights,
    including those claimed in these proceedings, apply to all “workers”.
    These proceedings
  40. Following a preliminary hearing, the employment tribunal decided that the
    claimants were “workers” who, although not employed under contracts of
    employment, worked for Uber London under “workers’ contracts” within the
    meaning of limb (b) of the statutory definition quoted at para 35 above. The tribunal
    further found that, for the purposes of the relevant legislation, the claimants were
    working for Uber London during any period when a claimant (a) had the Uber app
    switched on, (b) was within the territory in which he was authorised to work, and
    (c) was able and willing to accept assignments.
  41. An appeal by Uber from this decision to the Employment Appeal Tribunal
    was dismissed, as was a further appeal to the Court of Appeal (Sir Terence Etherton
    MR and Bean LJ, with Underhill LJ dissenting). The Court of Appeal granted Uber
    permission to appeal to this court.
    Page 12
    The main issue
  42. Limb (b) of the statutory definition of a “worker’s contract” has three
    elements: (1) a contract whereby an individual undertakes to perform work or
    services for the other party; (2) an undertaking to do the work or perform the services
    personally; and (3) a requirement that the other party to the contract is not a client
    or customer of any profession or business undertaking carried on by the individual.
  43. This case is concerned with the first of these requirements. It is not in dispute
    that the claimant drivers worked under contracts whereby they undertook to perform
    driving services personally; and it is not suggested that any Uber company was a
    client or customer of the claimants. The critical issue is whether, for the purposes of
    the statutory definition, the claimants are to be regarded as working under contracts
    with Uber London whereby they undertook to perform services for Uber London; or
    whether, as Uber contends, they are to be regarded as performing services solely for
    and under contracts made with passengers through the agency of Uber London.
    Uber’s case
  44. It is Uber’s case that, in answering this question, the correct starting point is
    to interpret the terms of the written agreements between Uber BV and drivers and
    between the Uber companies and passengers. Uber relies on the terms of these
    written agreements quoted above which state that, when a request to book a private
    hire vehicle made through the Uber app is accepted, a contract is thereby created
    between passenger and driver, to which no Uber entity is a party and under which
    the driver is solely responsible for providing transportation services to the passenger.
    Uber also relies on terms of the written agreements which state that the only role of
    Uber BV is to provide technology services and to act as a payment collection agent
    for the driver and that the only role of Uber London (and other Uber UK companies)
    is to act as a booking agent for drivers.
  45. Uber maintains that the approach adopted by the employment tribunal, the
    Employment Appeal Tribunal and the majority of the Court of Appeal was wrong
    in law because it involved disregarding, without any legal justification, the clear and
    unambiguous terms of the written agreements.
    Uber London not authorised to act as a booking agent
  46. There is a difficulty which, in my view, would be fatal for Uber’s case even
    if the correct approach to deciding whether the claimants were working under
    workers’ contracts with Uber London were simply to apply ordinary principles of
    Page 13
    the law of contract and agency. This difficulty stems from the fact that there is no
    written agreement between Uber London and drivers. In these circumstances the
    nature of their relationship has to be inferred from the parties’ conduct, considered
    in its relevant factual and legal context.
  47. It is an important feature of the context in which, as the employment tribunal
    found, Uber London recruits and communicates on a day to day basis with drivers
    that, as mentioned earlier: (1) it is unlawful for anyone in London to accept a private
    hire booking unless that person is the holder of a private hire vehicle operator’s
    licence for London; and (2) the only natural or legal person involved in the
    acceptance of bookings and provision of private hire vehicles booked through the
    Uber app which holds such a licence is Uber London. It is reasonable to assume, at
    least unless the contrary is demonstrated, that the parties intended to comply with
    the law in the way they dealt with each other.
  48. Uber maintains that the acceptance of private hire bookings by a licensed
    London PHV operator acting as agent for drivers would comply with the regulatory
    regime. I am not convinced by this. References in the Private Hire Vehicles
    (London) Act 1998 to “acceptance” of a private hire booking are reasonably
    understood to connote acceptance (personally and not merely for someone else) of
    a contractual obligation to carry out the booking and provide a vehicle for that
    purpose. This is implicit, for example, in section 4(2) of the Act quoted at para 31
    above. It would in principle be possible for Uber London both to accept such an
    obligation itself and also to contract on behalf of the driver of the vehicle. However,
    if this were the arrangement made, it would seem hard to avoid the conclusion that
    the driver, as well as Uber London, would be a person who accepts the booking by
    undertaking a contractual obligation owed directly to the passenger to carry it out.
    If so, the driver would be in contravention of section 2(1) of the Private Hire
    Vehicles (London) Act 1998 by accepting a private hire booking without holding a
    private hire vehicle operator’s licence for London. This suggests that the only
    contractual arrangement compatible with the licensing regime is one whereby Uber
    London as the licensed operator accepts private hire bookings as a principal (only)
    and, to fulfil its obligation to the passenger, enters into a contract with a
    transportation provider (be that an individual driver or a firm which in turn provides
    a driver) who agrees to carry out the booking for Uber London.
  49. Counsel for Uber sought to resist this interpretation of the legislation on the
    basis that the legislation was enacted in the context of “a long-established industry
    practice” under which PHV operators may merely act as agents for drivers who
    contract directly with passengers. Uber has adduced no evidence, however, of any
    such established practice which the Private Hire Vehicles (London) Act 1998 may
    be taken to have been intended to preserve. I will consider later two cases involving
    minicab firms which were said by counsel for Uber to show that the courts have
    endorsed such an agency model. But it is sufficient to say now that in neither case
    Page 14
    was any consideration given to whether such an arrangement would comply with
    the licensing regime. The same is true of cases also relied on by Uber (along with a
    notice published by HMRC in 2002) which are concerned with how VAT applies to
    the supply of private hire vehicles. That material in my view has no bearing on the
    issues raised in these proceedings.
  50. It is unnecessary, however, to express any concluded view on whether an
    agency model of operation would be compatible with the PHV licensing regime
    because there appears to be no factual basis for Uber’s contention that Uber London
    acts as an agent for drivers when accepting private hire bookings.
  51. It is true that the Rider Terms on which Uber contracts with passengers
    include a term (in clause 3 of Part 1, quoted at para 28 above) which states that Uber
    London (or other local Uber company) accepts private hire bookings “acting as
    disclosed agent for the Transportation Provider (as principal)” and that such
    acceptance “gives rise to a contract for the provision to [the rider] of transportation
    services between [the rider] and the Transportation Provider”. It is, however, trite
    law that a person (A) cannot create a contract between another person (B) and a third
    party merely by claiming or purporting to do so but only if A is (actually or
    ostensibly) authorised by B to act as B’s agent.
  52. Authority may be conferred by a contract between principal and agent. It
    cannot be said, however, that the Rider Terms establish a contract between drivers
    and Uber London. There is no evidence that drivers were ever sent the Rider Terms
    let alone consented to them. In any case the Rider Terms state that they constitute
    an agreement between the rider, Uber BV and the relevant local Uber company: they
    do not purport to record an agreement to which any driver is a party. In accordance
    with basic principles of contract and agency law, therefore, nothing stated in the
    Rider Terms is capable of conferring authority on Uber London to act as agent for
    any driver (or other “Transportation Provider”) nor of giving rise to a contract
    between a rider and a driver for the provision to the rider of transportation services
    by the driver.
  53. The only written agreements to which drivers were parties were agreements
    with Uber BV, the Dutch parent company. No other Uber company was a party to
    those agreements. In any case, although clause 2.2 of the Services Agreement
    describes what is to happen if a driver accepts a trip request “either directly or
    through an Uber Affiliate in the Territory acting as agent”, there is no provision
    which purports to confer the driver’s authority on any Uber Affiliate to accept such
    requests on his behalf.
    Page 15
  54. An agency relationship need not be contractual. What is required is an overt
    act by the principal conferring authority on the agent to act on the principal’s behalf.
    Even if lacking such actual authority, a person (A) who purports to act as agent for
    another (B) may still affect B’s legal relations with a third party under the principle
    of ostensible or apparent authority, but only if B has represented to the third party
    that A is authorised to act as B’s agent and the third party has relied on that
    representation.
  55. The employment tribunal made no finding that drivers did any overt act that
    conferred authority on Uber London to act as the driver’s agent in accepting
    bookings so as to create a contract between the driver and the passenger, nor that
    drivers did or said anything that represented to passengers that Uber London was
    authorised to act as their agent. Uber’s case that Uber London acted as a booking
    agent for drivers has been based solely on the written agreements referred to at paras
    22-28 above – which, for the reasons given, do not support it. When pressed during
    oral argument on how the alleged agency relationship between drivers and Uber
    London was created, leading counsel for Uber, Ms Dinah Rose QC, suggested that
    it was created when a driver attended Uber London’s offices in person and presented
    the documents required in order to be authorised to use the Uber app. So far as I am
    aware, this was the first time that such a suggestion had been made in these
    proceedings. Not only is it unsupported by any finding of the employment tribunal
    but, so far as this court has been shown, there was no evidence capable of founding
    such an inference.
  56. In order to found such an inference, it would be necessary to point, at the
    least, to a prior communication from Uber London to the individual concerned or
    other background facts known to both parties which would lead reasonable people
    in their position to understand that, by producing the documents required by Uber
    London, an individual who did so was thereby authorising Uber London to contract
    with passengers as his agent, rather than – as seems to me the natural inference –
    merely applying for a job as one of Uber’s drivers. There is no finding of the
    employment tribunal that any such communication was made nor that anything
    occurred during the “onboarding” process which could, even arguably, be construed
    as an act by the prospective driver appointing Uber London to act as his booking
    agent.
  57. Once the assertion that Uber London contracts as a booking agent for drivers
    is rejected, the inevitable conclusion is that, by accepting a booking, Uber London
    contracts as principal with the passenger to carry out the booking. In these
    circumstances Uber London would have no means of performing its contractual
    obligations to passengers, nor of securing compliance with its regulatory obligations
    as a licensed operator, without either employees or subcontractors to perform
    driving services for it. Considered against that background, it is difficult to see how
    Uber’s business could operate without Uber London entering into contracts with
    Page 16
    drivers (even if only on a per trip basis) under which drivers undertake to provide
    services to carry out the private hire bookings accepted by Uber London.
  58. Given the importance of the wider issue, however, I do not think it would be
    right to decide this appeal on this basis alone and without addressing Uber’s
    argument that the question whether an individual is a “worker” for the purpose of
    the relevant legislation ought in principle to be approached, as the starting point, by
    interpreting the terms of any applicable written agreements.
    The Autoclenz case
  59. In advancing this argument, Uber has to confront the decision of this court in
    Autoclenz Ltd v Belcher [2011] UKSC 41; [2011] ICR 1157.
  60. In the Autoclenz case the claimants worked as “valeters” performing car
    cleaning services which the company (Autoclenz) had contracted to provide to third
    parties. In order to obtain the work, the claimants were required to sign written
    contracts which stated that they were subcontractors and not employees of
    Autoclenz; that they were not obliged to provide services to the company, nor was
    the company obliged to offer work to them; and that they could provide suitably
    qualified substitutes to carry out the work on their behalf. As in the present case, the
    claimants brought proceedings claiming that they were “workers” for the purposes
    of the legislation conferring the rights to be paid the national minimum wage and to
    receive statutory paid leave. The employment tribunal held that the claimants came
    within both limbs of the definition of a “worker” and appeals by Autoclenz were
    dismissed at every level including the Supreme Court.
  61. In the Supreme Court the sole judgment was given by Lord Clarke of Stonecum-Ebony, with whom the other Justices agreed. In his discussion of the legal
    principles, Lord Clarke drew a distinction between certain principles “which apply
    to ordinary contracts and, in particular, to commercial contracts”, and “a body of
    case law in the context of employment contracts in which a different approach has
    been taken” (see para 21). It can be seen from a passage quoted by Lord Clarke (at
    para 20) from the judgment of Aikens LJ in the Court of Appeal [2010] IRLR 70,
    paras 87-89, that the principles applicable to ordinary contracts to which he was here
    referring were: (i) the “parol evidence rule”, whereby a contractual document is
    treated, at least presumptively, as containing the whole of the parties’ agreement;
    (ii) the signature rule, whereby a person who signs a contractual document is treated
    in law as bound by its terms irrespective of whether he or she has in fact read or
    understood them; and (iii) the principle that, generally, the only way in which a party
    to a written contract can argue that its terms do not accurately reflect the true
    Page 17
    agreement of the parties is by alleging that a mistake was made in drawing up the
    contract which the court can correct by ordering rectification.
  62. Whilst stating that nothing in his judgment was intended to alter these
    principles as they apply to ordinary contracts, Lord Clarke endorsed the view of
    Aikens LJ that, in the employment context, rectification principles are not in point
    and there may be reasons other than a mistake in setting out the contract terms why
    the written terms do not accurately reflect what the parties actually agreed.
  63. Beginning at para 22 of the judgment, Lord Clarke considered three cases in
    which “the courts have held that the employment tribunal should adopt a test that
    focuses on the reality of the situation where written documentation may not reflect
    the reality of the relationship”. From these cases he drew the conclusion (at para 28)
    that, in the employment context, it is too narrow an approach to say that a court or
    tribunal may only disregard a written term as not part of the true agreement between
    the parties if the term is shown to be a “sham”, in the sense that the parties had a
    common intention that the term should not create the legal rights and obligations
    which it gives the appearance of creating: see Snook v London and West Riding
    Investments Ltd [1967] 2 QB 786, 802 (Diplock LJ). Rather, the court or tribunal
    should consider what was actually agreed between the parties, “either as set out in
    the written terms or, if it is alleged those terms are not accurate, what is proved to
    be their actual agreement at the time the contract was concluded”: see para 32, again
    agreeing with observations of Aikens LJ in the Court of Appeal.
  64. After quoting (at para 34) a further statement of Aikens LJ contrasting the
    circumstances in which contracts relating to work or services are often concluded
    with “those in which commercial contracts between parties of equal bargaining
    power are agreed,” Lord Clarke ended his discussion of the law (at para 35) by
    saying:
    “So the relative bargaining power of the parties must be taken
    into account in deciding whether the terms of any written
    agreement in truth represent what was agreed and the true
    agreement will often have to be gleaned from all the
    circumstances of the case, of which the written agreement is
    only a part. This may be described as a purposive approach to
    the problem. If so, I am content with that description.”
  65. Applying that approach to the facts of the Autoclenz case, Lord Clarke
    concluded that, on the basis of findings of fact not capable of challenge on appeal,
    the employment tribunal was entitled to hold that the contractual documents did not
    reflect the true agreement between the parties – in particular insofar as the documents
    Page 18
    stated that Autoclenz was under no obligation to offer work to the claimants, nor
    they to accept it, and that the claimants had a right to provide a substitute. The
    tribunal was entitled to find that the actual understanding of the parties was that the
    claimants would be available to work, and would be offered work, whenever there
    was work available, and that they were required to perform the work personally. It
    followed that the employment tribunal was entitled to hold that the claimants were
    “workers” working under contracts of employment.
    Uber’s interpretation of the Autoclenz case
  66. Uber submits that what the Autoclenz case decided is that, for the purposes
    of applying a statutory classification, a court or tribunal may disregard terms of a
    written agreement if it is shown that the terms in question do not represent the “true
    agreement” or what was “actually agreed” between the parties, as ascertained by
    considering all the circumstances of the case including how the parties conducted
    themselves in practice. If, however, there is no inconsistency between the terms of
    the written agreement and how the relationship operated in reality, there is no basis
    for departing from the written agreement.
  67. Uber further submits that there is no inconsistency in the present case
    between the written agreements between Uber, drivers and passengers and how that
    tripartite relationship actually operated in practice. In particular, Uber argues that
    the facts found by the employment tribunal (or alternatively, which the tribunal
    should have found) are consistent with the written terms stipulating that the drivers
    were performing their services under contracts made with passengers through the
    agency of Uber London and not for or under any contract with any Uber company.
    Uber submits that there is in these circumstances no legal basis for finding that the
    terms of the written agreements did not reflect the true agreements between the
    parties and hence for departing from the classification of the parties’ relationships
    set out in the contractual documentation.
  68. This argument was accepted by Underhill LJ in his dissenting judgment in
    the Court of Appeal. In his view (stated at para 120):
    “It is an essential element in that ratio [ie of the Autoclenz case]
    that the terms of the written agreement should be inconsistent
    with the true agreement as established by the tribunal from all
    the circumstances. There is nothing in the reasoning of the
    Supreme Court that gives a tribunal a free hand to disregard
    written contractual terms which are consistent with how the
    parties worked in practice but which it regards as unfairly
    disadvantageous (whether because they create a relationship
    Page 19
    that does not attract employment protection or otherwise) and
    which might not have been agreed if the parties had been in an
    equal bargaining position.”
    Interpreting the statutory provisions
  69. The judgment of this court in the Autoclenz case made it clear that whether a
    contract is a “worker’s contract” within the meaning of the legislation designed to
    protect employees and other “workers” is not to be determined by applying ordinary
    principles of contract law such as the parol evidence rule, the signature rule and the
    principles that govern the rectification of contractual documents on grounds of
    mistake. Not only was this expressly stated by Lord Clarke but, had ordinary
    principles of contract law been applied, there would have been no warrant in the
    Autoclenz case for disregarding terms of the written documents which were
    inconsistent with an employment relationship, as the court held that the employment
    tribunal had been entitled to do. What was not, however, fully spelt out in the
    judgment was the theoretical justification for this approach. It was emphasised that
    in an employment context the parties are frequently of very unequal bargaining
    power. But the same may also be true in other contexts and inequality of bargaining
    power is not generally treated as a reason for disapplying or disregarding ordinary
    principles of contract law, except in so far as Parliament has made the relative
    bargaining power of the parties a relevant factor under legislation such as the Unfair
    Contract Terms Act 1977.
  70. Critical to understanding the Autoclenz case, as I see it, is that the rights
    asserted by the claimants were not contractual rights but were created by legislation.
    Thus, the task for the tribunals and the courts was not, unless the legislation required
    it, to identify whether, under the terms of their contracts, Autoclenz had agreed that
    the claimants should be paid at least the national minimum wage or receive paid
    annual leave. It was to determine whether the claimants fell within the definition of
    a “worker” in the relevant statutory provisions so as to qualify for these rights
    irrespective of what had been contractually agreed. In short, the primary question
    was one of statutory interpretation, not contractual interpretation.
  71. The modern approach to statutory interpretation is to have regard to the
    purpose of a particular provision and to interpret its language, so far as possible, in
    the way which best gives effect to that purpose. In UBS AG v Revenue and Customs
    Comrs [2016] UKSC 13; [2016] 1 WLR 1005, paras 61-68, Lord Reed (with whom
    the other Justices of the Supreme Court agreed) explained how this approach
    requires the facts to be analysed in the light of the statutory provision being applied
    so that if, for example, a fact is of no relevance to the application of the statute
    construed in the light of its purpose, it can be disregarded. Lord Reed cited the pithy
    Page 20
    statement of Ribeiro PJ in Collector of Stamp Revenue v Arrowtown Assets Ltd
    (2003) 6 ITLR 454, para 35:
    “The ultimate question is whether the relevant statutory
    provisions, construed purposively, were intended to apply to
    the transaction, viewed realistically.”
    The purpose of protecting workers
  72. The general purpose of the employment legislation invoked by the claimants
    in the Autoclenz case, and by the claimants in the present case, is not in doubt. It is
    to protect vulnerable workers from being paid too little for the work they do,
    required to work excessive hours or subjected to other forms of unfair treatment
    (such as being victimised for whistleblowing). The paradigm case of a worker whom
    the legislation is designed to protect is an employee, defined as an individual who
    works under a contract of employment. In addition, however, the statutory definition
    of a “worker” includes in limb (b) a further category of individuals who are not
    employees. The purpose of including such individuals within the scope of the
    legislation was clearly elucidated by Mr Recorder Underhill QC giving the judgment
    of the Employment Appeal Tribunal in Byrne Bros (Formwork) Ltd v Baird [2002]
    ICR 667, para 17(4):
    “[T]he policy behind the inclusion of limb (b) … can only have
    been to extend the benefits of protection to workers who are in
    the same need of that type of protection as employees stricto
    sensu – workers, that is, who are viewed as liable, whatever
    their formal employment status, to be required to work
    excessive hours (or, in the cases of Part II of the Employment
    Rights Act 1996 or the National Minimum Wage Act 1998, to
    suffer unlawful deductions from their earnings or to be paid too
    little). The reason why employees are thought to need such
    protection is that they are in a subordinate and dependent
    position vis-Ă -vis their employers: the purpose of the
    Regulations is to extend protection to workers who are,
    substantively and economically, in the same position. Thus the
    essence of the intended distinction must be between, on the one
    hand, workers whose degree of dependence is essentially the
    same as that of employees and, on the other, contractors who
    have a sufficiently arm’s-length and independent position to be
    treated as being able to look after themselves in the relevant
    respects.”
    Page 21
  73. The Regulations referred to in this passage are the Working Time Regulations
    1998 which implemented Directive 93/104/EC (“the Working Time Directive”); and
    a similar explanation of the concept of a worker has been given in EU law. Although
    there is no single definition of the term “worker”, which appears in a number of
    different contexts in the Treaties and EU legislation, there has been a degree of
    convergence in the approach adopted. In Allonby v Accrington and Rossendale
    College (Case C-256/01) [2004] ICR 1328; [2004] ECR I-873 the European Court
    of Justice held, at para 67, that in the Treaty provision which guarantees male and
    female workers equal pay for equal work (at that time, article 141 of the EC Treaty):
    “… there must be considered as a worker a person who, for a
    certain period of time, performs services for and under the
    direction of another person in return for which he receives
    remuneration …”
    The court added (at para 68) that the authors of the Treaty clearly did not intend that
    the term “worker” should include “independent providers of services who are not in
    a relationship of subordination with the person who receives the services”. In the
    EU case law which is specifically concerned with the meaning of the term “worker”
    in the Working Time Directive, the essential feature of the relationship between
    employer and worker is identified in the same terms as in para 67 of the Allonby
    judgment: Union Syndicale Solidaires Isere v Premier Ministre (Case C-428/09)
    EU:C:2010:612; [2010] ECR I-9961, para 28; Fenoll v Centre d’Aide par le Travail
    “La Jouvene” (Case C-316/13) EU:C:2015:2000; [2016] IRLR 67, para 29; and
    Syndicatul Familia Constanta v Directia Generala de Asistenta Sociala si Protectia
    Copilului Constanta (Case C-147/17) EU:C:2018:926; [2019] ICR 211, para 41. As
    stated by the Court of Justice of the European Union (CJEU) in the latter case, “[i]t
    follows that an employment relationship [ie between employer and worker] implies
    the existence of a hierarchical relationship between the worker and his employer”
    (para 42).
  74. In Hashwani v Jivraj [2011] UKSC 40; [2011] 1 WLR 1872 the Supreme
    Court followed this approach in holding that an arbitrator was not a person employed
    under “a contract personally to do any work” for the purpose of legislation
    prohibiting discrimination on the grounds of religion or belief. Lord Clarke, with
    whom the other members of the court agreed, identified (at para 34) the essential
    questions underlying the distinction between workers and independent contractors
    outside the scope of the legislation as being:
    “whether, on the one hand, the person concerned performs
    services for and under the direction of another person in return
    for which he or she receives remuneration or, on the other hand,
    he or she is an independent provider of services who is not in a
    Page 22
    relationship of subordination with the person who receives the
    services.”
  75. In the Bates van Winkelhof case at para 39, Baroness Hale cautioned that,
    while “subordination may sometimes be an aid to distinguishing workers from other
    self-employed people, it is not a freestanding and universal characteristic of being a
    worker.” In that case the Supreme Court held that a solicitor who was a member of
    a limited liability partnership was a worker essentially for the reasons that she could
    not market her services as a solicitor to anyone other than the LLP and was an
    integral part of their business. While not necessarily connoting subordination,
    integration into the business of the person to whom personal services are provided
    and the inability to market those services to anyone else give rise to dependency on
    a particular relationship which may also render an individual vulnerable to
    exploitation.
  76. The correlative of the subordination and/or dependency of employees and
    workers in a similar position to employees is control exercised by the employer over
    their working conditions and remuneration. As the Supreme Court of Canada
    observed in McCormick v Fasken Martineau DuMoulin LLP 2014 SCC 39; [2014]
    2 SCR 108, para 23:
    “Deciding who is in an employment relationship … means, in
    essence, examining how two synergetic aspects function in an
    employment relationship: control exercised by an employer
    over working conditions and remuneration, and corresponding
    dependency on the part of a worker. … The more the work life
    of individuals is controlled, the greater their dependency and,
    consequently, their economic, social and psychological
    vulnerability in the workplace …”
    See also the illuminating discussion in G Davidov, “A Purposive Approach to
    Labour Law” (2016), Chapters 3 and 6. It is these features of work relations which
    give rise to a situation in which such relations cannot safely be left to contractual
    regulation and are considered to require statutory regulation. This point applies in
    relation to all the legislative regimes relied on in the present case and no distinction
    is to be drawn between the interpretation of the relevant provision as it appears in
    the Working Time Regulations 1998 (which implement the Working Time
    Directive), the National Minimum Wage Act 1998 and the Employment Rights Act
    1996.
  77. Once this is recognised, it can immediately be seen that it would be
    inconsistent with the purpose of this legislation to treat the terms of a written
    Page 23
    contract as the starting point in determining whether an individual falls within the
    definition of a “worker”. To do so would reinstate the mischief which the legislation
    was enacted to prevent. It is the very fact that an employer is often in a position to
    dictate such contract terms and that the individual performing the work has little or
    no ability to influence those terms that gives rise to the need for statutory protection
    in the first place. The efficacy of such protection would be seriously undermined if
    the putative employer could by the way in which the relationship is characterised in
    the written contract determine, even prima facie, whether or not the other party is to
    be classified as a worker. Laws such as the National Minimum Wage Act were
    manifestly enacted to protect those whom Parliament considers to be in need of
    protection and not just those who are designated by their employer as qualifying for
    it.
  78. This point can be illustrated by the facts of the present case. The Services
    Agreement (like the Partner Terms before it) was drafted by Uber’s lawyers and
    presented to drivers as containing terms which they had to accept in order to use, or
    continue to use, the Uber app. It is unlikely that many drivers ever read these terms
    or, even if they did, understood their intended legal significance. In any case there
    was no practical possibility of negotiating any different terms. In these
    circumstances to treat the way in which the relationships between Uber, drivers and
    passengers are characterised by the terms of the Services Agreement as the starting
    point in classifying the parties’ relationship, and as conclusive if the facts are
    consistent with more than one possible legal classification, would in effect be to
    accord Uber power to determine for itself whether or not the legislation designed to
    protect workers will apply to its drivers.
  79. This is, as I see it, the relevance of the emphasis placed in the Autoclenz case
    (at para 35) on the relative bargaining power of the parties in the employment
    context and the reason why Lord Clarke described the approach endorsed in that
    case of looking beyond the terms of any written agreement to the parties’ “true
    agreement” as “a purposive approach to the problem”.
    Restrictions on contracting out
  80. Such an approach is further justified by the fact that all the relevant statutes
    or statutory regulations conferring rights on workers contain prohibitions against
    contracting out. Thus, section 203(1) of the Employment Rights Act 1996 provides:
    “Any provision in an agreement (whether a contract of
    employment or not) is void in so far as it purports –
    Page 24
    (a) to exclude or limit the operation of any provision
    of this Act, or
    (b) to preclude a person from bringing any
    proceedings under this Act before an employment
    tribunal.”
    Section 49(1) of the National Minimum Wage Act 1998 and regulation 35(1) of the
    Working Time Regulations 1998 are in similar terms.
  81. These provisions, as I read them, apply to any provision in an agreement
    which can be seen, on an objective consideration of the facts, to have as its object
    excluding or limiting the operation of the legislation. It is just as inimical to the aims
    of the legislation to allow its protection to be limited or excluded indirectly by the
    terms of a contract as it is to allow that to be done in direct terms.
  82. Take, for example, the following provisions contained, respectively, in
    clauses 2.3 and 2.4 of the Services Agreement:
    “Customer acknowledges and agrees that Customer’s provision
    of Transportation Services to Users creates a legal and direct
    business relationship between Customer and the User, to which
    neither Uber [BV] nor any of its Affiliates in the Territory is a
    party. …”
    “… Uber and its Affiliates in the Territory do not, and shall not
    be deemed to, direct or control Customer or its Drivers
    generally or in their performance under this Agreement
    specifically, including in connection with the operation of
    Customer’s business, the provision of Transportation Services,
    the acts or omissions of Drivers, or the operation and
    maintenance of any Vehicles.”
    It is arguable that these provisions are in any case ineffective, as it is for the courts
    and not the parties (still less someone who is not a party) to determine the legal
    effect of a contract and whether it falls within one legal category or another: see eg
    Street v Mountford [1985] AC 809, 819.
  83. If or in so far, however, as these contractual provisions purport to agree
    matters of fact rather than law, then (leaving aside the fact that the relevant
    Page 25
    “Affiliates” including Uber London were not parties to the agreement) Uber would
    no doubt seek to rely on case law which has recognised a principle of “contractual
    estoppel” – whereby parties can bind themselves by contract to accept a particular
    state of affairs even if they know that state of affairs to be untrue: see eg First Tower
    Trustees Ltd v CDS (Superstores International) Ltd [2018] EWCA Civ 1396; [2019]
    1 WLR 637, para 47. This would preclude a driver from asserting in any legal
    proceedings that he is performing transportation services for or under a contract with
    any Uber company or that he is directed or controlled in connection with the
    provision of transportation services by any Uber company. The result – which was
    patently the drafter’s intention – would be to prevent a driver from claiming that he
    falls within the statutory definition of a “worker” so as to qualify for the rights
    conferred on workers by statutory provisions such as those contained in the National
    Minimum Wage Act 1998. As such, these provisions in the agreement are just as
    much provisions which purport to exclude or limit the operation of the legislation as
    would be a term stating that “Customer acknowledges and agrees that Customer is
    not and shall not be deemed to be a ‘worker’ for the purposes of the National
    Minimum Wage Act 1998” or a term stating that “Customer acknowledges and
    agrees that, notwithstanding the provisions of the National Minimum Wage Act
    1998, Customer shall not be entitled to be paid the national minimum wage.” In each
    case the object of the provision is the same. Consequently, in determining whether
    drivers are entitled under the provisions of the 1998 Act to be paid the national
    minimum wage, section 49(1) of the Act renders the clauses quoted above void. The
    same applies to all other provisions in the Services Agreement which can be seen to
    have as their object precluding a driver from claiming rights conferred on workers
    by the applicable legislation.
    Applying the definition of a “worker”
  84. If, as I conclude, the way in which the relevant relationships are characterised
    in the written agreements is not the appropriate starting point in applying the
    statutory definition of a “worker”, how is the definition to be applied?
  85. In the Autoclenz case it was said (at para 35) that “the true agreement will
    often have to be gleaned from all the circumstances of the case, of which the written
    agreement is only a part.” More assistance is provided by the decision of the House
    of Lords in Carmichael v National Power plc [1999] 1 WLR 2042. That case
    concerned tour guides engaged to act “on a casual as required basis”. The guides
    later claimed to be employees and therefore entitled by statute to a written statement
    of their terms of employment. Their case was that an exchange of correspondence
    between the parties in March 1989 constituted a contract, which was to be classified
    as a contract of employment. The industrial tribunal rejected this case and found
    that, when not working as guides, the claimants were not in any contractual
    relationship with the respondent. The tribunal made this finding on the basis of: (a)
    the language of the correspondence; (b) the way in which the relationship had
    Page 26
    operated; and (c) evidence of the parties as to their understanding of it. The House
    of Lords held that this was the correct approach. Lord Irvine of Lairg LC said at p
    2047C that:
    “… it would only be appropriate to determine the issue in these
    cases solely by reference to the documents in March 1989, if it
    appeared from their own terms and/or from what the parties
    said or did then, or subsequently, that they intended them to
    constitute an exclusive memorial of their relationship. The
    industrial tribunal must be taken to have decided that they were
    not so intended but constituted one, albeit important, relevant
    source of material from which they were entitled to infer the
    parties’ true intention …”
  86. In the Carmichael case there was no formal written agreement. The Autoclenz
    case shows that, in determining whether an individual is an employee or other
    worker for the purpose of the legislation, the approach endorsed in the Carmichael
    case is appropriate even where there is a formal written agreement (and even if the
    agreement contains a clause stating that the document is intended to record the entire
    agreement of the parties). This does not mean that the terms of any written
    agreement should be ignored. The conduct of the parties and other evidence may
    show that the written terms were in fact understood and agreed to be a record,
    possibly an exclusive record, of the parties’ rights and obligations towards each
    other. But there is no legal presumption that a contractual document contains the
    whole of the parties’ agreement and no absolute rule that terms set out in a
    contractual document represent the parties’ true agreement just because an
    individual has signed it. Furthermore, as discussed, any terms which purport to
    classify the parties’ legal relationship or to exclude or limit statutory protections by
    preventing the contract from being interpreted as a contract of employment or other
    worker’s contract are of no effect and must be disregarded.
  87. This last point provides one rationale for the conclusion reached in the
    Autoclenz case itself. The findings of the employment tribunal justified the inference
    that the terms of the written agreements which stated that the claimants were
    subcontractors and not employees of Autoclenz, that they were not obliged to
    provide services to the company, nor was the company obliged to offer work to
    them, and that they could provide suitably qualified substitutes to carry out the work
    on their behalf, had all been inserted with the object of excluding the operation of
    employment legislation including the National Minimum Wage Act 1998 and the
    Working Time Regulations 1998. Those provisions in the agreements were therefore
    void.
    Page 27
  88. In determining whether an individual is a “worker”, there can, as Baroness
    Hale said in the Bates van Winkelhof case at para 39, “be no substitute for applying
    the words of the statute to the facts of the individual case.” At the same time, in
    applying the statutory language, it is necessary both to view the facts realistically
    and to keep in mind the purpose of the legislation. As noted earlier, the
    vulnerabilities of workers which create the need for statutory protection are
    subordination to and dependence upon another person in relation to the work done.
    As also discussed, a touchstone of such subordination and dependence is (as has
    long been recognised in employment law) the degree of control exercised by the
    putative employer over the work or services performed by the individual concerned.
    The greater the extent of such control, the stronger the case for classifying the
    individual as a “worker” who is employed under a “worker’s contract”.
  89. This approach is also consistent with the case law of the CJEU which, as
    noted at para 72 above, treats the essential feature of a contract between an employer
    and a worker as the existence of a hierarchical relationship. In a recent judgment the
    Grand Chamber of the CJEU has emphasised that, in determining whether such a
    relationship exists, it is necessary to take account of the objective situation of the
    individual concerned and all the circumstances of his or her work. The wording of
    the contractual documents, while relevant, is not conclusive. It is also necessary to
    have regard to how relevant obligations are performed in practice: see AFMB Ltd v
    Raad van bestuur van de Sociale verzekeringsbank (Case C-610/18)
    EU:C:2020:565; [2020] ICR 1432, paras 60-61.
  90. Section 28(1) of the National Minimum Wage Act establishes a presumption
    that an individual qualifies for the national minimum wage unless the contrary is
    established. This is not a case, however, which turns on the burden of proof.
    Status of the claimants in this case
  91. The claimant drivers in the present case had in some respects a substantial
    measure of autonomy and independence. In particular, they were free to choose
    when, how much and where (within the territory covered by their private hire vehicle
    licence) to work. In these circumstances it is not suggested on their behalf that they
    performed their services under what is sometimes called an “umbrella” or
    “overarching” contract with Uber London – in other words, a contract whereby they
    undertook a continuing obligation to work. The contractual arrangements between
    drivers and Uber London did subsist over an extended period of time. But they did
    not bind drivers during periods when drivers were not working: rather, they
    established the terms on which drivers would work for Uber London on each
    occasion when they chose to log on to the Uber app.
    Page 28
  92. Equally, it is well established and not disputed by Uber that the fact that an
    individual is entirely free to work or not, and owes no contractual obligation to the
    person for whom the work is performed when not working, does not preclude a
    finding that the individual is a worker, or indeed an employee, at the times when he
    or she is working: see eg McMeechan v Secretary of State for Employment [1997]
    ICR 549; Cornwall County Council v Prater [2006] EWCA Civ 102; [2006] ICR
  93. As Elias J (President) said in James v Redcats (Brands) Ltd [2007] ICR 1006,
    para 84:
    “Many casual or seasonal workers, such as waiters or fruit
    pickers or casual building labourers, will periodically work for
    the same employer but often neither party has any obligations
    to the other in the gaps or intervals between engagements.
    There is no reason in logic or justice why the lack of worker
    status in the gaps should have any bearing on the status when
    working. There may be no overarching or umbrella contract,
    and therefore no employment status in the gaps, but that does
    not preclude such a status during the period of work.”
    I agree, subject only to the qualification that, where an individual only works
    intermittently or on a casual basis for another person, that may, depending on the
    facts, tend to indicate a degree of independence, or lack of subordination, in the
    relationship while at work which is incompatible with worker status: see Windle v
    Secretary of State for Justice [2016] EWCA Civ 459; [2016] ICR 721, para 23.
  94. In many cases it is not in dispute that the claimant is doing work or
    performing services personally for another person but there is an issue as to whether
    that person is to be classified as the claimant’s employer or as a client or customer
    of the claimant. The situation in the present case is different in that there are three
    parties involved: Uber, drivers and passengers. But the focus must still be on the
    nature of the relationship between drivers and Uber. The principal relevance of the
    involvement of third parties (ie passengers) is the need to consider the relative
    degree of control exercised by Uber and drivers respectively over the service
    provided to them. A particularly important consideration is who determines the price
    charged to the passenger. More generally, it is necessary to consider who is
    responsible for defining and delivering the service provided to passengers. A further
    and related factor is the extent to which the arrangements with passengers afford
    drivers the potential to market their own services and develop their own independent
    business.
  95. In all these respects, the findings of the employment tribunal justified its
    conclusion that, although free to choose when and where they worked, at times when
    Page 29
    they are working drivers work for and under contracts with Uber (and, specifically,
    Uber London). Five aspects of the tribunal’s findings are worth emphasising.
  96. First and of major importance, the remuneration paid to drivers for the work
    they do is fixed by Uber and the drivers have no say in it (other than by choosing
    when and how much to work). Unlike taxi fares, fares for private hire vehicles in
    London are not set by the regulator. However, for rides booked through the Uber
    app, it is Uber that sets the fares and drivers are not permitted to charge more than
    the fare calculated by the Uber app. The notional freedom to charge a passenger less
    than the fare set by Uber is of no possible benefit to drivers, as any discount offered
    would come entirely out of the driver’s pocket and the delivery of the service is
    organised so as to prevent a driver from establishing a relationship with a passenger
    that might generate future custom for the driver personally (see the fifth point,
    discussed below). Uber also fixes the amount of its own “service fee” which it
    deducts from the fares paid to drivers. Uber’s control over remuneration further
    extends to the right to decide in its sole discretion whether to make a full or partial
    refund of the fare to a passenger in response to a complaint by the passenger about
    the service provided by the driver (see para 20 above).
  97. Second, the contractual terms on which drivers perform their services are
    dictated by Uber. Not only are drivers required to accept Uber’s standard form of
    written agreement but the terms on which they transport passengers are also imposed
    by Uber and drivers have no say in them.
  98. Third, although drivers have the freedom to choose when and where (within
    the area covered by their PHV licence) to work, once a driver has logged onto the
    Uber app, a driver’s choice about whether to accept requests for rides is constrained
    by Uber. Unlike taxi drivers, PHV operators and drivers are not under any regulatory
    obligation to accept such requests. Uber itself retains an absolute discretion to accept
    or decline any request for a ride. Where a ride is offered to a driver through the Uber
    app, however, Uber exercises control over the acceptance of the request by the driver
    in two ways. One is by controlling the information provided to the driver. The fact
    that the driver, when informed of a request, is told the passenger’s average rating
    (from previous trips) allows the driver to avoid low-rated passengers who may be
    problematic. Notably, however, the driver is not informed of the passenger’s
    destination until the passenger is picked up and therefore has no opportunity to
    decline a booking on the basis that the driver does not wish to travel to that particular
    destination.
  99. The second form of control is exercised by monitoring the driver’s rate of
    acceptance (and cancellation) of trip requests. As described in para 18 above, a
    driver whose percentage rate of acceptances falls below a level set by Uber London
    (or whose cancellation rate exceeds a set level) receives an escalating series of
    Page 30
    warning messages which, if performance does not improve, leads to the driver being
    automatically logged off the Uber app and shut out from logging back on for ten
    minutes. This measure was described by Uber in an internal document quoted by the
    employment tribunal as a “penalty”, no doubt because it has a similar economic
    effect to docking pay from an employee by preventing the driver from earning
    during the period while he is logged out of the app. Uber argues that this practice is
    justified because refusals or cancellations of trip requests cause delay to passengers
    in finding a driver and lead to customer dissatisfaction. I do not doubt this. The
    question, however, is not whether the system of control operated by Uber is in its
    commercial interests, but whether it places drivers in a position of subordination to
    Uber. It plainly does.
  100. Fourth, Uber exercises a significant degree of control over the way in which
    drivers deliver their services. The fact that drivers provide their own car means that
    they have more control than would most employees over the physical equipment
    used to perform their work. Nevertheless, Uber vets the types of car that may be
    used. Moreover, the technology which is integral to the service is wholly owned and
    controlled by Uber and is used as a means of exercising control over drivers. Thus,
    when a ride is accepted, the Uber app directs the driver to the pick-up location and
    from there to the passenger’s destination. Although, as mentioned, it is not
    compulsory for a driver to follow the route indicated by the Uber app, customers
    may complain if a different route is chosen and the driver bears the financial risk of
    any deviation from the route indicated by the app which the passenger has not
    approved (see para 8 above).
  101. I have already mentioned the control exercised by monitoring a driver’s
    acceptance and cancellation rates for trips and excluding the driver temporarily from
    access to the Uber app if he fails to maintain the required rates of acceptance and
    non-cancellation. A further potent method of control is the use of the ratings system
    whereby passengers are asked to rate the driver after each trip and the failure of a
    driver to maintain a specified average rating will result in warnings and ultimately
    in termination of the driver’s relationship with Uber (see paras 13 and 18 above). It
    is of course commonplace for digital platforms to invite customers to rate products
    or services. Typically, however, such ratings are merely made available as
    information which may assist customers in choosing which product or service to
    buy. Under such a system the incentive for the supplier of the product or service to
    gain high ratings is simply the ordinary commercial incentive of satisfying
    customers in the hope of attracting future business. The way in which Uber makes
    use of customer ratings is materially different. The ratings are not disclosed to
    passengers to inform their choice of driver: passengers are not offered a choice of
    driver with, for example, a higher price charged for the services of a driver who is
    more highly rated. Rather, the ratings are used by Uber purely as an internal tool for
    managing performance and as a basis for making termination decisions where
    customer feedback shows that drivers are not meeting the performance levels set by
    Page 31
    Uber. This is a classic form of subordination that is characteristic of employment
    relationships.
  102. A fifth significant factor is that Uber restricts communication between
    passenger and driver to the minimum necessary to perform the particular trip and
    takes active steps to prevent drivers from establishing any relationship with a
    passenger capable of extending beyond an individual ride. As mentioned, when
    booking a ride, a passenger is not offered a choice among different drivers and their
    request is simply directed to the nearest driver available. Once a request is accepted,
    communication between driver and passenger is restricted to information relating to
    the ride and is channelled through the Uber app in a way that prevents either from
    learning the other’s contact details. Likewise, collection of fares, payment of drivers
    and handling of complaints are all managed by Uber in a way that is designed to
    avoid any direct interaction between passenger and driver. A stark instance of this
    is the generation of an electronic document which, although styled as an “invoice”
    from the driver to the passenger, is never sent to the passenger and, though available
    to the driver, records only the passenger’s first name and not any further details (see
    para 10 above). Further, drivers are specifically prohibited by Uber from exchanging
    contact details with a passenger or contacting a passenger after the trip ends other
    than to return lost property (see para 12 above).
  103. Taking these factors together, it can be seen that the transportation service
    performed by drivers and offered to passengers through the Uber app is very tightly
    defined and controlled by Uber. Furthermore, it is designed and organised in such a
    way as to provide a standardised service to passengers in which drivers are perceived
    as substantially interchangeable and from which Uber, rather than individual drivers,
    obtains the benefit of customer loyalty and goodwill. From the drivers’ point of
    view, the same factors – in particular, the inability to offer a distinctive service or to
    set their own prices and Uber’s control over all aspects of their interaction with
    passengers – mean that they have little or no ability to improve their economic
    position through professional or entrepreneurial skill. In practice the only way in
    which they can increase their earnings is by working longer hours while constantly
    meeting Uber’s measures of performance.
  104. I would add that the fact that some aspects of the way in which Uber operates
    its business are required in order to comply with the regulatory regime – although
    many features are not – cannot logically be, as Uber has sought to argue, any reason
    to disregard or attach less weight to those matters in determining whether drivers
    are workers. To the extent that forms of control exercised by Uber London are
    necessary in order to comply with the law, that merely tends to show that an
    arrangement whereby drivers contract directly with passengers and Uber London
    acts solely as an agent is not one that is legally available.
    Page 32
    Booking agents
  105. It is instructive to compare Uber’s method of operation and relationship with
    drivers with digital platforms that operate as booking agents for suppliers of, for
    example, hotel or other accommodation. There are some similarities. For example,
    a platform through which customers can book accommodation is likely to have
    standard written contract terms that govern its relationships with suppliers and with
    customers. It will typically handle the collection of payment and deduct a service
    fee which it fixes. It may require suppliers to comply with certain rules and standards
    in relation to the accommodation offered. It may handle complaints and reserve the
    right to determine whether a customer or supplier should compensate the other if a
    complaint is upheld.
  106. Nevertheless, such platforms differ from Uber in how they operate in several
    fundamental ways. Notably, the accommodation offered is not a standardised
    product defined by the platform. Customers are offered a choice among a variety of
    different hotels or other types of accommodation (as the case may be), each with its
    own distinctive characteristics and location. Suppliers are also responsible for
    defining and delivering whatever level of service in terms of comfort and facilities
    etc they choose to offer. Apart from the service fee, it is, crucially, the supplier and
    not the platform which sets the price. The platform may operate a ratings system but
    the ratings are published in order to assist customers in choosing among different
    suppliers; they are not used as a system of internal performance measurement and
    control by the platform over suppliers. Nor does the platform restrict communication
    between the supplier and the customer or seek to prevent them from dealing directly
    with each other on a future occasion. The result of these features is that suppliers of
    accommodation available for booking through the platform are in competition with
    each other to attract business through the price and quality of the service they supply.
    They are properly regarded as carrying on businesses which are independent of the
    platform and as performing their services for the customers who purchase those
    services and not for the platform.
    The Secret Hotels2 case
  107. A platform of this kind was the subject of Secret Hotels2 Ltd (formerly Med
    Hotels Ltd) v Revenue and Customs Comrs [2014] UKSC 16; [2014] 2 All ER 685,
    a case on which Uber has strongly relied. In that case a company (“Med”) marketed
    hotel rooms and holiday accommodation through a website. One difference from the
    typical model described above was that Med reserved many hotel rooms in its own
    name, for which it paid in advance. The issue was whether, for the purposes of
    assessing liability for VAT in accordance with Directive 2006/112/EC (“the
    Principal VAT Directive”), Med was purchasing accommodation from hoteliers and
    supplying it to customers as a principal or whether Med fell within a category of
    Page 33
    persons who “act solely as intermediaries” to whom more favourable tax treatment
    applied.
  108. The Supreme Court held that the correct legal analysis of the tripartite
    relationship between Med, hoteliers and customers was that Med marketed and sold
    hotel accommodation to customers as the agent of the hoteliers and was in these
    circumstances acting solely as an intermediary for VAT purposes. In analysing the
    relationship, Lord Neuberger of Abbotsbury (with whom the other members of the
    court agreed) identified the correct approach at para 34 as follows:
    “(i) the right starting point is to characterise the nature of the
    relationship between Med, the customer, and the hotel, in the
    light of … ‘the contractual documentation’, (ii) one must next
    consider whether that characterisation can be said to represent
    the economic reality of the relationship in the light of any
    relevant facts, and (iii) if so, the final issue is the result of this
    characterisation so far as article 306 [of the Principal VAT
    Directive] is concerned.”
  109. Secret Hotels2 was not an employment case: it concerned the classification
    of a relationship for VAT purposes. In applying the VAT legislation, the proper
    approach – established by binding decisions of the CJEU cited at paras 22-29 of the
    judgment in Secret Hotels2 – is informed by the policy that “taxable persons are
    generally free to choose the organisational structures and the form of transactions
    which they consider to be most appropriate for their economic activities and for the
    purposes of limiting their tax burdens”, albeit that this is subject to an exception for
    “abusive transactions”: see Revenue and Customs Comrs v RBS Deutschland
    Holdings GmbH (Case C-277/09) EU:C:2010:810; [2011] STC 345, para 53, cited
    by Lord Neuberger in Secret Hotels2 at para 24. I have already explained why a
    different approach is required in applying the employment legislation invoked in the
    present case, which is underpinned by different policy considerations.
  110. That said, even if the relationships in the Secret Hotels2 case were viewed
    through the lens of employment law, I see no reason to question the analysis that
    Med was acting solely as a booking agent for hoteliers. For the reasons given at para
    104 above, the manner in which such a platform operates is materially different from
    Uber’s business model. Even the practice of reserving hotel rooms in Med’s own
    name was, as Lord Neuberger pointed out at para 49 of the judgment, consistent
    with its status as an intermediary: a customer who subsequently booked one of the
    rooms would not contract with Med, but would contract through Med with the
    hotelier; and, if not all reserved rooms were booked by customers at the hotel for the
    season in question, the amount paid by Med was carried forward to the next season.
    Page 34
    In short, I do not consider that the decision of this court in Secret Hotels2 provides
    any support for Uber’s case in the present proceedings.
    Minicab drivers
  111. I mentioned earlier (at para 48 above) the reliance placed by Uber on two
    judicial decisions involving minicab firms which are said to have recognised in an
    employment context that such firms may act as booking agents for drivers who
    provide transportation services directly to passengers under contracts with
    passengers and do not work for the minicab firm. Uber contends that its own
    business model is similar to that of such firms, with the principal differences being
    only the scale of its operations and the fact that Uber uses software to take bookings
    rather than doing so by telephone.
  112. The principal case relied on is Mingeley v Pennock (t/a Amber Cars) [2004]
    EWCA Civ 328; [2004] ICR 727, in which the claimant driver brought a claim
    against a private hire vehicle operator trading under the name of “Amber Cars”
    alleging discrimination on the ground of race. The claimant owned his own vehicle
    and was responsible for obtaining a PHV driver’s licence. He was one of some 225
    drivers who paid a weekly fee to Amber Cars for access to what was initially a radio
    and later a computer system through which trip requests from customers were
    allocated to drivers. There was no obligation to work but, when he chose to work,
    the driver was obliged to wear a uniform and to apply a fixed scale of charges set by
    the operator. He collected and was entitled to keep the full fare paid by the customer.
    The operator had a procedure for dealing with complaints from passengers about the
    conduct of the driver and had the power to order a refund of the fare to the passenger.
  113. The Court of Appeal affirmed the decision of the employment tribunal that it
    had no jurisdiction to hear the claim as the claimant was not “employed” by the
    operator within the meaning of section 78 of the Race Relations Act 1976. Maurice
    Kay LJ (with whom Sir Martin Nourse and Buxton LJ agreed) regarded it as fatal to
    the claim that the claimant was “free to work or not to work at his own whim or
    fancy” (para 14) and held that the absence of an obligation to work placed him
    beyond the reach of section 78. Buxton LJ gave as an additional reason that, even
    when working, a driver was not employed by Amber Cars “under … a contract
    personally to execute any work or labour” as his only such obligation was owed to
    the passenger.
  114. The definition of “employment” and related expressions in section 78 of the
    Race Relations Act 1976 has been substantially replicated in section 83(2)(a) of the
    Equality Act 2010, which defines “employment” to include “employment under a
    contract of employment, a contract of apprenticeship or a contract personally to do
    Page 35
    work”. Although not the same as the definition of a “worker” and a “worker’s
    contract” in section 230(3) of the 1996 Act, the two definitions have been held to
    have substantially the same effect: see Pimlico Plumbers Ltd v Smith [2018] UKSC
    29; [2018] ICR 1511, paras 13-15.
  115. It is not necessary for present purposes to express any view on whether the
    Mingeley case was correctly decided. I do not accept, however, that the fact that the
    claimant in that case was free to work as and when he chose was a sufficient reason
    for holding that, at times when he was working, he was not employed under a
    contract to do work for the firm. If that conclusion was justified on the facts of the
    Mingeley case, it would have to be on the basis that the claimant was not to be
    regarded as working for the minicab firm when transporting passengers in
    circumstances where the firm did not receive any money in respect of any individual
    trip undertaken by him. This arrangement was materially different from Uber’s
    business model.
  116. The other employment case involving a minicab firm on which Uber relies is
    Khan v Checkers Cars Ltd, an unreported decision of the Employment Appeal
    Tribunal handed down on 16 December 2005. The facts were that the British
    Airports Authority had granted the respondent firm (“Checkers”) an exclusive
    licence to provide a taxi service at Gatwick airport. The firm had a fleet of over 200
    drivers, one of whom was the claimant, who plied for hire at the airport taxi-rank.
    Checkers took a commission and imposed numerous conditions on its drivers,
    including requiring them to charge set fares, use fixed routes and wear a uniform.
    Drivers were entirely free to choose whether and when they worked but they were
    not permitted to drive for anyone else. The issue was whether the claimant had a
    right not to be unfairly dismissed, which depended on showing that he had been
    continuously employed by Checkers under a contract of employment for a period of
    not less than two years: see section 108 of the Employment Rights Act 1996.
  117. The Employment Appeal Tribunal upheld the finding of the employment
    tribunal that the claimant did not satisfy this requirement because the absence of any
    obligation to work other than when he chose was inconsistent with the conclusion
    that there was any contract of employment which subsisted when the claimant was
    not working. Langstaff J, however, also observed, obiter, at para 32 of the judgment:
    “If it had been material to our decision, we would have been
    inclined to find that …, on the findings of fact that the tribunal
    made, the contract went no further than to amount to a licence
    by Checkers to permit the claimant to offer himself as a private
    hire taxi driver to individual passengers on terms dictated by
    the administrative convenience of Checkers and BAA.”
    Page 36
    Given the extent of the control exercised by Checkers over the manner in which
    drivers carried out their work, I cannot agree that such a finding would have been
    justified.
  118. In making the observation quoted above, Langstaff J was drawing an analogy
    with the facts of Cheng Yuen v Royal Hong Kong Golf Club [1998] ICR 131. In that
    case the claimant worked as a caddie for individual members of the respondent golf
    club. He was issued by the club with a number, a uniform and a locker. Caddying
    work was allocated to available caddies in strict rotation. They were not obliged to
    make themselves available for work and received no guarantee of work. The club
    was not obliged to give them work or to pay anything other than the amount of the
    fee per round owed by the individual golfer for whom they had caddied. On an
    appeal to the Privy Council the majority of the Board held that the only reasonable
    view of the facts found was that the claimant had not been employed under a contract
    of employment by the club either on a continuing basis or separately each time he
    agreed to act as a caddie, and that the club did no more than grant him a licence to
    enter into contracts with individual golfers on terms dictated by the administrative
    convenience of the club and its members. Lord Hoffmann, who dissented, thought
    that it was more realistic to regard the claimant as a casual employee of the club,
    particularly when (as he observed at p 139) “the claimant had to work for the person
    to whom he was allocated according to the club’s system at a rate of pay fixed by
    the club and in the manner determined by the club”. Without expressing any view
    on the correctness of the decision, I do not consider that this case provides a relevant
    analogy in determining whether the employment tribunal was entitled to find that
    the claimants in the present case are workers.
  119. In Quashie v Stringfellow Restaurants Ltd [2012] EWCA Civ 1735; [2013]
    IRLR 99 the claimant was a lap dancer who performed for the entertainment of
    guests at the respondent’s clubs. An important factual finding was that the
    respondent was not obliged to pay the claimant any money at all. Rather, the
    claimant paid the respondent a fee for each night that she worked. Doing so enabled
    her to earn payments from the guests for whom she danced. She negotiated those
    payments with the guests and took the risk that on any particular night she might be
    out of pocket. The Court of Appeal held that on these facts the employment tribunal
    had been entitled to find that the claimant was not employed under a contract of
    employment (either for each engagement or on a continuous basis). Again, the facts
    were very different from those of the present case and I do not find this decision of
    any assistance.
    The employment tribunal’s decision
  120. It is firmly established that, where the relationship has to be determined by
    an investigation and evaluation of the factual circumstances in which the work is
    Page 37
    performed, the question of whether work is performed by an individual as an
    employee (or a worker in the extended sense) or as an independent contractor is to
    be regarded as a question of fact to be determined by the first level tribunal. Absent
    a misdirection of law, the tribunal’s finding on this question can only be impugned
    by an appellate court (or appeal tribunal) if it is shown that the tribunal could not
    reasonably have reached the conclusion under appeal: see Lee Ting Sang v Chung
    Chi-Keung [1990] 2 AC 374, 384-385; Clark v Oxfordshire Health Authority [1998]
    IRLR 125, paras 38-39; the Quashie case, para 9.
  121. On the facts found in the present case, and in particular those which I have
    emphasised at paras 94-101 above, I think it clear that the employment tribunal was
    entitled to find that the claimant drivers were “workers” who worked for Uber
    London under “worker’s contracts” within the meaning of the statutory definition.
    Indeed, that was, in my opinion, the only conclusion which the tribunal could
    reasonably have reached.
  122. It does not matter in these circumstances that certain points made by the
    employment tribunal in the reasons given for its decision are open to criticism, nor
    is it necessary to discuss such particular criticisms, since none of the errors or alleged
    errors affects the correctness of the tribunal’s decision. I agree with the majority of
    the Court of Appeal that there are some points made by the employment tribunal
    which are misplaced (see in particular para 93 of the Court of Appeal’s judgment).
    I also agree with the analysis set out at paras 96 and 97 of that judgment of the 13
    considerations on which the tribunal principally based its finding that drivers work
    for Uber. I agree with the majority of the Court of Appeal that those considerations,
    viewed in the round, provided an ample basis for the tribunal’s finding.
    Working Time
  123. The secondary question which arises in the light of this conclusion is: during
    what periods of time were the claimants working?
  124. The Working Time Regulations 1998 and the National Minimum Wage
    Regulations 2015 each contain provisions for measuring working time. But before
    those provisions are applied, it is necessary to identify the periods during which the
    individual concerned is a “worker” employed under a “worker’s contract” so as to
    fall within the scope of the legislation.
  125. As mentioned earlier, the employment tribunal found that a driver was
    “working” under such a contract during any period when he (a) had the Uber app
    switched on, (b) was within the territory in which he was authorised to use the app,
    Page 38
    and (c) was ready and willing to accept trips. Uber contends that it was not open to
    the tribunal in law to make this finding and that the tribunal should have found that
    the claimants (on the assumption that they were “workers” at all) were only working
    under workers’ contracts during periods when they were actually driving passengers
    to their destinations. Alternatively, Uber contends that the tribunal should have
    found that a claimant was only working under such a contract from the moment
    when (and not until) he accepted a trip request.
  126. I think it clear – as did all the members of the Court of Appeal, including the
    dissenting judge, Underhill LJ, if he was wrong on the main issue – that a driver
    enters into, and is working under, a contract with Uber London whereby the driver
    undertakes to perform services for Uber London, if not before, then at the latest
    when he accepts a trip. If the driver afterwards cancels the trip, that signifies only
    that the obligation undertaken to pick up the passenger and carry the passenger to
    his or her destination is then terminated. It does not mean that no obligation was
    ever undertaken. The more difficult question is whether the employment tribunal
    was entitled to find – as by implication it did – that a worker’s contract came into
    existence at an earlier stage when a claimant driver logged onto the Uber app.
  127. Uber argues that it is clear from the tribunal’s own findings that drivers when
    logged onto the Uber app are under no obligation to accept trips. They are free to
    ignore or decline trip requests as often as they like, subject only to the consequence
    that, if they repeatedly decline requests, they will be automatically logged off the
    Uber app and required to wait for ten minutes before they can log back on again.
    Furthermore, when logged onto the Uber app, drivers are at liberty to accept other
    work, including driving work offered through another digital platform (see para 16
    above). Counsel for Uber submitted that, on these facts, a finding that a driver who
    switches on the Uber app undertakes a contractual obligation to work for Uber
    London is not rationally sustainable. Nor can the fact that the driver is ready and
    willing to accept trips logically alter the position so as to give rise to such an
    obligation.
  128. The fact, however, that an individual has the right to turn down work is not
    fatal to a finding that the individual is an employee or a worker and, by the same
    token, does not preclude a finding that the individual is employed under a worker’s
    contract. What is necessary for such a finding is that there should be what has been
    described as “an irreducible minimum of obligation”: see Nethermere (St Neots) Ltd
    v Gardiner [1984] ICR 612, 623 (Stephenson LJ), approved by the House of Lords
    in Carmichael v National Power plc [1999] 1 WLR 2042, 2047. In other words, the
    existence and exercise of a right to refuse work is not critical, provided there is at
    least an obligation to do some amount of work.
    Page 39
  129. In the present case Uber London in the Welcome Packet of material issued to
    new drivers referred to logging onto the Uber app as “going on duty” and instructed
    drivers that: “Going on duty means you are willing and able to accept trip requests”
    (see para 17 above). Logging onto the Uber app was thus presented by Uber London
    itself to drivers as undertaking an obligation to accept work if offered. The
    employment tribunal also found that the third in the graduated series of messages
    sent to a driver whose acceptance rate of trip requests fell below a prescribed level
    included a statement that “being online with the Uber app is an indication that you
    are available to take trips, in accordance with your Services Agreement.” The
    reference in this message to the Services Agreement must have been to clause 2.6.2,
    which stated:
    “Customer acknowledges and agrees that repeated failure by a
    Driver to accommodate User requests for Transportation
    Services while such Driver is logged in to the Driver App
    creates a negative experience for Users of Uber’s mobile
    application. Accordingly, Customer agrees and shall ensure
    that if a Driver does not wish to provide Transportation
    Services for a period of time, such Driver will log off of the
    Driver App.”
  130. Counsel for the third respondent suggested that this clause is inconsistent
    with clause 2.4 of the Services Agreement, which provided that:
    “Customer and its Drivers retain the option, via the Driver App,
    to decline or ignore a User’s request for Transportation
    Services via the Uber Services, or to cancel an accepted request
    … subject to Uber’s then-current cancellation policies.”
    I do not agree that these clauses are inconsistent. The position both as specified in
    the Services Agreement and in practice was that, on the one hand, a driver while
    logged onto the Uber app was free to decline or ignore any individual trip request
    (and might well, for example, choose to do so if the request came from a passenger
    with a low rating). But, on the other hand, the driver was required to be generally
    willing and available to take trips, and a repeated failure by a driver to accept trip
    requests was treated as a breach of that requirement.
  131. Whilst the irreducible minimum of obligation on drivers to accept work was
    not precisely defined in the Services Agreement, the employment tribunal was
    entitled to conclude that it was in practice delineated by Uber’s criteria for logging
    drivers off the Uber app if they failed to maintain a prescribed rate of acceptances.
    Uber seeks to characterise this system as merely a way of seeking to ensure that
    Page 40
    drivers do not remain logged onto the app, perhaps through inadvertence whilst
    away from their vehicle, at times when they are not in fact available to work.
    However, if that were the only purpose of automatically logging off a driver, it is
    hard to see why the driver should then be shut out from logging back onto the Uber
    app for a ten-minute period. It was open to the tribunal on the evidence, including
    Uber’s internal documents, to find that this exclusion from access to the app was
    designed to operate coercively and that it was reasonably perceived by drivers, and
    was intended by Uber to be perceived, as a penalty for failing to comply with an
    obligation to accept a minimum amount of work.
  132. It follows that the employment tribunal was, in my view, entitled to conclude
    that, by logging onto the Uber app in London, a claimant driver came within the
    definition of a “worker” by entering into a contract with Uber London whereby he
    undertook to perform driving services for Uber London. I do not consider that the
    third condition identified by the tribunal that the driver was in fact ready and willing
    to accept trips can properly be regarded as essential to the existence of a worker’s
    contract; nor indeed did the tribunal assert that it was. But it is reasonable to treat it,
    as the tribunal did, as a further condition which must be satisfied in order to find that
    a driver is “working” under such a contract.
  133. This brings me to the question of what periods during which a driver is
    employed under a worker’s contract count as working time.
    The Working Time Regulations
  134. For the purpose of the Working Time Regulations 1998, “working time” is
    defined in regulation 2(1), in relation to a worker, as “any period during which he is
    working, at his employer’s disposal and carrying out his activity or duties”.
  135. There is no difficulty in principle in a finding that time when a driver is “on
    call” falls within this definition. A number of decisions of the CJEU establish that,
    for the purpose of the Working Time Directive, to which the UK Regulations aim to
    give effect and which defines “working time” in the same way, time spent on call
    counts as “working time” if the worker is required to be at or near his or her place
    of work. For example, in Ville de Nivelles v Matzak (Case C-518/15) EU:C:2018:82;
    [2018] ICR 869 the CJEU held that time spent by firefighters on stand-by at their
    homes, which were required to be within eight minutes travelling distance of the fire
    station, was working time.
  136. On the facts of the present case, a driver’s place of work is wherever his
    vehicle is currently located. Subject to the point I consider next, in the light of this
    Page 41
    case law the tribunal was justified in finding that all time spent by a driver working
    under a worker’s contract with Uber London, including time spent “on duty” logged
    onto the Uber app in London available to accept a trip request, is “working time”
    within the meaning of the Working Time Directive and Regulations.
  137. The point that – like the majority of the Court of Appeal and Judge Eady QC
    in the Employment Appeal Tribunal – I have found more difficult is whether a driver
    logged onto the Uber app in the area in which he is licensed to work can be said to
    be “working, at his employer’s disposal and carrying out his activity or duties” if
    during such times the driver is equally ready and willing to accept a trip request
    received from another PHV operator. It was argued with force by counsel for Uber
    that a driver cannot reasonably be said to be working for and at the disposal of Uber
    London if, while logged onto the Uber app, he is also at the same time logged onto
    another app provided by a competitor of Uber which operates a similar service.
  138. I have concluded that this question cannot be answered in the abstract. I agree
    with Judge Eady QC when she said in her judgment dismissing Uber’s appeal to the
    Employment Appeal Tribunal (at para 126) that it is a matter of fact and degree.
    Like the majority of the Court of Appeal, I also agree with her that:
    “If the reality is that Uber’s market share in London is such that
    its drivers are, in practical terms, unable to hold themselves out
    as available to any other PHV operator, then, as a matter of fact,
    [when they have the Uber app switched on] they are working
    at [Uber London’s] disposal as part of the pool of drivers it
    requires to be available within the territory at any one time. …
    if, however, it is genuinely the case that drivers are able to also
    hold themselves out as at the disposal of other PHV operators
    when waiting for a trip, the same analysis would not apply.”
  139. So far as this court has been shown, no evidence was adduced at the hearing
    in the employment tribunal in 2016 that there was at that time any other app-based
    PHV transportation service operating in London or that drivers logged into the Uber
    app were as a matter of practical reality also able to hold themselves out as at the
    disposal of other PHV operators when waiting for a trip. No finding was made by
    the tribunal on this subject. In these circumstances I do not consider that the tribunal
    was wrong to find that periods during which its three conditions were met
    constituted “working time” for the purpose of the Working Time Regulations 1998.
    Page 42
    The National Minimum Wage Regulations
  140. What counts as working time for the purposes of the right to be paid the
    national minimum wage is defined by the National Minimum Wage Regulations
  141. These regulations contain complex provisions for measuring hours worked
    depending on how the work is classified. Before the employment tribunal there was
    an issue as to whether a driver’s working hours should be classified as “time work”,
    as Uber argued, or as “unmeasured work”, as the tribunal held. It was accepted by
    Uber that “time work” could only be the appropriate category if the driver is working
    only when carrying a passenger and not otherwise. As I have concluded that the
    tribunal was entitled to reject that contention, it follows that the tribunal was also
    entitled to find that the claimants’ working hours were not “time work”. As it was
    common ground that those hours did not fall within the definitions of “salaried
    work” or “output work”, it further follows that the tribunal was entitled to find that
    they constituted “unmeasured work”, which is a residual or default category. On this
    point too, therefore, there is no basis for interfering with the employment tribunal’s
    decision.
    Conclusion
  142. For all the reasons given, I would dismiss this appeal.
    Postscript
  143. After the hearing of the appeal but before this judgment was handed down,
    Lord Kitchin fell ill and it was uncertain when he would return to work. With the
    agreement of the parties, the presiding judge, Lord Reed, gave a direction under
    section 43(3) of the Constitutional Reform Act 2005 that the court was still duly
    constituted by the remaining six Justices, all of whom are permanent judges.
