Intermediary or Operator? Legal Limits on Price-Setting and

Introduction
Digital platforms in the transportation sector often position themselves as mere intermediaries connecting drivers and passengers. By claiming to be “information society services” (ISS) under EU law or simple agents under UK law, these companies seek to avoid the regulatory burdens placed on transport operators. However, EU and UK legal frameworks draw a clear line: an intermediary cannot set the prices for rides or assign drivers to customers without losing its legal status as a neutral platform. Once a platform goes beyond a “mere conduit” role and exerts control over key terms of the service, it is treated as a transport operator in the eyes of the law. This paper analyzes why intermediaries in EU and UK transport cannot lawfully fix fares or dispatch drivers if they wish to remain within the legal safe harbor for intermediaries. We examine the E-Commerce Directive (Directive 2000/31/EC) — particularly Articles 12–15 and Recital 42 — and relevant case law, and we discuss the implications for platforms like CarTrawler, Suntransfers, and Welcome Pickups that cross the line from intermediary to transport provider.
Directive 2000/31/EC: Liability Safe Harbors for Passive Intermediaries
The EU’s Directive 2000/31/EC (the “E-Commerce Directive”) provides liability exemptions for online intermediary services, but only under strict conditions of neutrality. In essence, an information society service provider is shielded from liability for third-party content only when its role is purely technical, automatic, and passive . Recital 42 of the Directive emphasizes that the liability exemptions “cover only cases where the activity of the information society service provider is limited to the technical process of operating and giving access to a communication network… this activity is of a mere technical, automatic and passive nature, which implies that the provider has neither knowledge of nor control over the information which is transmitted or stored” . In other words, to benefit from the safe harbor, the intermediary must remain neutral as to the content it carries. Any knowledge or control over the information (for example, intervening in what is being transmitted) can remove the service from the protected category.
The Directive’s Article 12 (“mere conduit”) illustrates this principle. It provides that an ISS provider who transmits information from users or provides access to a network will not be liable for that information “on condition that” the provider (a) “does not initiate the transmission,” (b) “does not select the receiver of the transmission,” and (c) “does not select or modify the information contained in the transmission” . These criteria mean the intermediary should function like a digital pipeline – simply carrying requests and responses between users and providers without altering them or selectively delivering them. Similarly, Article 13 (caching) and Article 14 (hosting) grant safe harbors for, respectively, the temporary storage and hosting of user-provided information, again under conditions including no modification of the data and lack of awareness of illegality . Notably, Article 14(2) even clarifies that the hosting exemption “shall not apply when the recipient of the service is acting under the authority or the control of the provider” – if the supposedly independent user (e.g. a driver posting information) is effectively controlled by the platform, the platform cannot claim to be a neutral host. Finally, Article 15 prohibits EU Member States from imposing general obligations on intermediaries to monitor information they transmit or store, reinforcing that intermediaries are not expected to actively manage or curate user content .
Recital 43 of the Directive highlights that an intermediary must not modify the information it handles to enjoy the “mere conduit” or “caching” liability shields . Only purely technical manipulations (like data formatting or compression that do not alter content) are permitted without losing immunity . In short, EU law establishes that a “mere conduit” intermediary should be a passive carrier of information. The pricing of a service, the terms of an offer, and the selection of the service provider are all considered part of the “information” being transmitted between the parties. So, an ISS platform that determines these terms itself – such as setting the price for a ride or unilaterally assigning a driver to a customer – is no longer passive or neutral. It is modifying or controlling the content of the transaction, which takes it outside the scope of the E-Commerce Directive’s immunity .
Control over Pricing and Driver Assignment as “Content” Modification
Under the above principles, the fare for a journey and the choice of driver are not just business decisions – they are legally viewed as the content of the service offer. A truly neutral platform would allow these elements to be determined by the transacting parties (the driver/operator and the passenger) with the platform merely relaying the information. For example, a neutral marketplace might let multiple drivers quote their own prices for a passenger’s requested trip, leaving the passenger to choose among them. By contrast, if the platform itself sets a fixed, non-negotiable fare for the trip and forbids any deviation, it has taken over the role of the service provider in determining price. Likewise, if the platform automatically assigns a driver to a customer’s request (dispatching a particular driver without input from the customer or independent choice by the driver), it has usurped control of which provider will execute the service. These actions amount to the platform injecting its own decisions into the content of the service agreement, rather than merely facilitating a connection.
Indeed, indicators such as fixed pricing and dispatching are red flags that a platform is functioning as more than an intermediary. A recent industry analysis noted that a “true intermediary” in transport allows providers to set their own prices, whereas a “‘grey’ platform” typically sets uniform fares and prevents suppliers or users from negotiating or seeing alternatives . For instance, a grey-market ride platform may impose “fixed fares for suppliers,” prohibit drivers from adjusting their rates, and only show the customer the single price the platform has determined . This means the platform is controlling the transactional information (the price) rather than letting the price emerge from driver competition or agreement with the passenger. The Court of Justice of the EU (CJEU) has highlighted such control over pricing as a decisive factor in classifying a service as transport rather than digital intermediation. In the Uber case (discussed below), Uber’s fare-setting model – where the app, not the driver, fixes the price – was instrumental in the Court’s conclusion that Uber is performing more than a neutral intermediation .
Similarly, the act of assigning drivers to trips is a form of controlling the service content. A neutral platform might list available drivers and let the user select, or let drivers choose which requests to accept. But when a platform directly dispatches a specific driver to a passenger, it takes an active role in executing the service . The difference is highlighted by comparing two CJEU cases: one concerning Uber and another involving a Romanian platform called Star Taxi App. Uber’s model gave it significant influence over how rides are carried out – Uber’s system matches riders with drivers automatically and dictates terms of the ride, leading the court to view Uber as performing the transport service. In contrast, Star Taxi App operated more like a classifieds service for licensed taxi drivers: it did not set fares or assign drivers, leaving those aspects to the existing taxi regime. The CJEU accepted that Star Taxi App “merely facilitated licensed taxi connections” and thus remained a genuine ISS intermediary, whereas *“Uber’s influence over ride pricing and driver activity led to its classification as a transport provider” . This comparison illustrates that platforms which refrain from controlling price and driver selection can claim the legal privileges of intermediaries, but once they start managing these elements, they cross into the territory of transport operators.
EU Law: From “Information Society Service” to Transport Service Provider
When an intermediary crosses the line from passive facilitator to active orchestrator of a transport service, EU law no longer treats it as a protected ISS. Asociación Profesional Elite Taxi v. Uber (CJEU, 2017) was the landmark case confirming this principle. In that case, a Barcelona taxi association argued Uber’s ride-hailing platform was essentially an illegal taxi operation. The CJEU examined Uber’s activities and ruled that Uber “must be classified as a service in the field of transport,” not as an information society service, because the intermediation provided by Uber was “inextricably linked to a transport service” . The Court noted several critical facts about Uber’s model: Uber recruited the drivers (non-professional individuals using their own vehicles), set or at least fixed the fare that passengers pay, and exercised a decisive influence over the conditions of the service . In particular, Uber controlled essential elements of the service – notably the price of the ride and the conduct of drivers (through ratings, rules, and assignment of trips) – such that “without Uber’s platform, the drivers would not have access to the passengers” . Because Uber effectively organizes and manages the transport transaction, the Court determined it is “more than a simple matchmaking platform” and is “effectively a transport operator” subject to transport regulations .
This classification had significant consequences. Once deemed a transport service (rather than a mere ISS), Uber could no longer invoke the protections of the E-Commerce Directive or the EU freedom to provide information services to avoid complying with local taxi laws . The CJEU explicitly held that EU Member States are free to regulate services like Uber as transport services – including imposing licensing requirements, service standards, or outright bans on unlicensed operations – without running afoul of EU single market rules . In a subsequent case, Uber France SAS (CJEU, 2018), Uber was prosecuted for facilitating unlicensed transport (the UberPop service). Uber argued France should have notified the European Commission before regulating it, on the theory that Uber was an ISS. The CJEU flatly rejected this defense, reaffirming that Uber’s service is in the transport field, not a cross-border information service, so France’s enforcement of taxi licensing laws did not need prior EU approval . In essence, the EU courts recognized that a company which coordinates rides by setting fares and assigning drivers for remuneration is providing a transport service, not merely a digital marketplace . Such a company “cannot hide behind being a ‘tech platform’ to circumvent taxi and private hire regulations” .
The implication is clear: any platform that mirrors Uber’s level of control over the service will be treated like Uber under the law . If an online platform fixes the prices for rides and pairs customers with drivers as part of its normal operation, then under EU law it is “inherently linked to transport” and not an ISS in the intended sense . National authorities can require it to obtain transport operator licenses and comply with all sector-specific rules. The liability safe harbors of the E-Commerce Directive no longer apply, because the platform is no longer acting as a neutral conduit of someone else’s content but is instead providing the core service itself. To put it succinctly: a platform that “looks like Uber, works like Uber, and earns like Uber, should be regulated like Uber” – a sentiment increasingly echoed by courts and regulators in the EU.
UK Law: Intermediary vs Operator in Private Hire Regulation
In the United Kingdom, even apart from EU law, a similar principle has evolved in domestic transport regulation. UK private hire and taxi laws have long required that any person or company that accepts or arranges a ride booking must be properly licensed as an operator. For example, under London’s regulatory regime, the Private Hire Vehicles (London) Act 1998 makes it unlawful for anyone to “make provision for the invitation or acceptance of” private hire bookings without holding an operator’s licence . The effect of this and similar laws nationwide (like the Local Government (Miscellaneous Provisions) Act 1976 for towns outside London) is that any entity interposed between passenger and driver in arranging a ride is deemed an operator by law. Operating without the requisite licence is a criminal offence .
For years, some ride intermediaries tried to style themselves as mere “agents” of the drivers to sidestep direct licensing. They would claim that the actual contract for hire was only between the passenger and the driver, with the platform just acting as a booking agent on the driver’s behalf. This argument was tested decisively in United Trade Action Group (UTAG) Ltd v. Transport for London [2021] EWHC 3290 (Admin). In that case, brought by a coalition of black cab interests, the High Court examined whether Uber and similar app-based services could lawfully operate on an “agent” model. The court “decisively rejected the notion that a PHV operator can be a mere agent for drivers.” Uber (with support from another app, Free Now) had sought a declaration that it would comply with the law by accepting bookings as agent for its drivers, rather than contracting directly with passengers . The High Court disagreed. It held that under the 1998 Act, when a licensed operator accepts a booking, it must undertake the ride as a principal party to the contract with the passenger . In the court’s words, “acceptance of a booking by the operator will create a contract between the operator and the passenger” whereby the operator promises to provide the transportation service as principal (i.e. the operator **itself undertakes to send a vehicle and driver for the passenger) . The operator cannot evade liability by claiming to act on behalf of the driver – any such arrangement is incompatible with the regulatory scheme . This ruling made it clear that Uber’s previous practice of disavowing a contract with the passenger (pretending the driver was the only carrier) was not lawful . In practical terms, after UTAG v TfL, Uber and similar platforms had to change their terms and business models to acknowledge that they contract with passengers directly as the provider of transport . The “agent” fiction was no longer tenable in UK private hire law.
Importantly, this principle now applies throughout the UK. In Uber Britannia Ltd v Sefton MBC [2023] EWHC 1731 (Admin), the High Court confirmed that the same rule (from the London case) applies under the 1976 Act outside London . Any company that accepts a private hire booking anywhere in England and Wales is legally the operator and “bears direct responsibility for the journey” . The courts stressed this interpretation promotes public safety and accountability: passengers know whom they can hold accountable (the licensed operator) and regulators know whom to oversee . In summary, UK law now squarely treats accepting and assigning a ride booking as an operator function, not a broker service. A platform cannot legally present itself as a mere intermediary once it is controlling essential aspects of the booking (taking the booking and dispatching a driver) – if it does so without an operator’s licence, it is operating unlawfully . The UK legal expectation is that “any entity that accepts a private hire booking is… the operator”, with all attendant obligations .
Thus, in the UK context, the act of setting the fare and allocating a driver to a booking is firmly within the domain of the licensed operator’s role. An unlicensed platform engaging in those activities will be treated by courts and regulators as an illegal operator, regardless of how it labels itself in contracts. The economic reality trumps the contractual labels: if the platform walks, talks, and acts like a transport operator, the law will consider it one .
Crossing the Line: Case Studies of “Intermediaries” Acting as Operators
The legal principles above shed light on why certain well-known transport platforms in the UK and EU are violating intermediary restrictions by setting prices or assigning drivers. Platforms such as CarTrawler, Suntransfers, and Welcome Pickups often market themselves as mere booking agents or “marketplaces,” but their operational model tells a different story. By controlling the price of rides and orchestrating which driver fulfills a booking, they step into the role of a transport service provider – triggering legal obligations and losing the legal immunities afforded to neutral intermediaries.
What is the difference between a taxi intermediary and an operator for airport transfers?
An intermediary platform connects drivers and passengers without setting prices or owning vehicles, like some booking apps. An operator controls the service, including fares and driver contracts, which subjects them to local taxi regulations. Travelers using intermediaries may see variable prices based on driver rates, while operators must follow fixed tariffs, such as London's black cabs with a £3.80 starting fare.
Can ride-hailing apps legally set their own prices for airport rides in the EU?
Under EU law, apps claiming intermediary status as information society services cannot directly set prices to avoid transport regulations, but many courts rule them as operators if they influence fares. This means apps like Uber must comply with local price caps in cities like Paris, where maximum rates are €1.06 per km daytime. Check city rules before booking to avoid unexpected surges.
How does UK law limit price-setting for taxi platforms at airports?
UK law treats platforms as agents if they only match riders without controlling prices, but if they set dynamic fares, they act as operators under the Local Government Act. This requires adherence to licensed taxi zones at airports like Heathrow, with minicab fares starting at £5 for short trips. Platforms must display regulated maximums, such as £50 for a 10-mile airport run during peak hours.
