1. Introduction and Background
This decision concerns the boundary between legitimate airport management and unlawful commercial gatekeeping. ER Travel Limited (“ER”) operated an online, low-cost car rental business from premises outside Dublin Airport. It sought permission to collect arriving customers and return departing customers through a dedicated shuttle service. It did not seek terminal desks, airport vehicle storage, or the full facilities available to on-airport concessionaires.
Dublin Airport Authority PLC (“DAA”), the state-owned airport operator, maintained that car rental businesses could obtain operational access only by successfully participating in its competitive concession tender. ER was invited to tender but declined: its business depended on avoiding the costs of an integrated on-airport operation. It nevertheless expressed willingness to pay for an appropriate off-airport access arrangement.
The concession packages combined terminal desks, forward parking spaces, spaces at the Eastlands facility, and dedicated shuttle rights. Successful operators paid the higher of a minimum guaranteed annual amount and a percentage of revenue. Aggregate concession payments were approximately €21 million in 2018 and exceeded €34 million in 2024.
DAA also possessed statutory airport-management powers. Under section 15 of the State Airports Act 2004, it made the Airport Bye-Laws 2014, S.I. 618/2014. Regulation 10 prohibited business activities within an airport without permission, while regulation 4 made contravention an offence. DAA invoked these provisions against ER through cease-and-desist correspondence, airport police operations, fixed penalty notices, and District Court prosecutions. The prosecutions were dismissed or struck out in 2017 and 2018; DAA did not appeal.
ER commenced these proceedings in 2019, advancing competition law, ultra vires, and fair-procedures claims. Its application for interlocutory injunctive relief was refused, but it continued operating without DAA’s permission during the litigation. The High Court regarded that continued operation as precarious, rather than proof that the access dispute had ceased to matter.
3. Legal Reasoning
3.1 Pleadings, Evidence, and the Judicial Function
DAA argued that ER had failed adequately to identify the alleged concerted practice, its market setting, and its consequences. The court rejected that submission because the pleadings sufficiently disclosed the case and the trial demonstrated DAA’s detailed understanding of it.
DAA had reserved a right to seek strike-out but never brought such an application. It had also received answers to requests for particulars without seeking further and better particulars. These omissions reinforced the court’s conclusion that the claimed uncertainty was not credible.
This was not a ruling that inadequate pleadings become sufficient merely because a defendant fails to challenge them early. The court expressly retained ER’s burden of proving its case on the balance of probabilities. Its conclusion rested on substantive adequacy, procedural history, and the issues actually explored through disclosure, expert evidence, and cross-examination.
The judgment also emphasised that economic experts assist rather than replace judicial evaluation. The court could draw reasonable inferences from commercial documents and conduct without requiring an economist to supply a separate opinion for every inference.
3.2 Market Definition: Location Does Not Determine Competitive Boundaries
The court rejected a division between on-airport and off-airport rental providers. Both served passengers seeking short-term vehicle hire connected with Dublin Airport, and both constrained each other competitively. The parties had already agreed that any short-term rental market included both types of supplier; the court resolved the remaining geographic and product-market issues in ER’s favour.
The economic inquiry concerned substitution: would customers switch between the services in response to a sustained price increase? Differences in convenience did not prevent the services from belonging to one market, particularly for price-sensitive leisure customers.
DAA’s internal documents were especially important. They described off-site rental as a growing threat, recognised ER’s influence on pricing, and expressed concern that off-site competition could reduce concession tender receipts. Those documents supported both the unified market definition and the inference that enforcement served commercial protection rather than neutral infrastructure management.
3.3 Concerted Practice: Commercial Complaints Followed by Protective Enforcement
The Article 101 TFEU and section 4 case did not depend on a formal agreement or conventional price-fixing. ER alleged that incumbents sought DAA’s intervention to suppress a lower-cost rival, and that DAA cooperated because its concession income depended on their revenues.
The contemporaneous correspondence went beyond complaints about traffic or unauthorised stopping. Operators complained that ER was “pricing way below the market”, forcing them to respond on price, and taking revenue from both concessionaires and DAA. The trade association sought “immediate action” and later “more effective action” to protect business interests.
DAA’s response included concentrated enforcement operations described internally as a “blitz”. A commercial manager also offered shopping vouchers for the first five fixed penalty notices issued to ER employees. The judgment treated the offer as evidence of pressure for stronger enforcement; it did not establish that vouchers were actually paid.
The decisive inference arose from the combination of communications, shared commercial incentives, and responsive action. Incumbents sought protection against competition, and DAA deployed control over airport access to provide it.
Restriction by object and by effect
The court found a restriction by object: the practical purpose of the coordination was to prevent ER from using the pick-up and drop-off facilities needed for its competing model. That finding made a separate demonstration of restrictive effects unnecessary to establish the infringement.
Nevertheless, the court also found restrictive effects. Enforcement created operational uncertainty, interrupted customer transport, and made ER’s service more burdensome and less attractive. A competitor need not disappear before competition can be restricted.
The judgment’s rejection of a de minimis defence should be read in that context. It classified the proven coordination as harmful by object; it should not be understood as establishing that any hostile intention or complaint about a competitor automatically infringes Article 101.
After finding infringement, the court required DAA to substantiate its asserted justification. It did not undertake a separately structured assessment of every condition for exemption under Article 101(3).
3.4 Dominance Through Control of Access
DAA argued that it could not dominate car rental services because it did not supply them. The court instead focused on its control over the means by which rental providers reached airport passengers: land, terminals, parking, access points, permissions, and enforcement.
The reasoning is best understood as addressing the exercise of gatekeeping power over a dependent service market. DAA’s non-participation in direct rental supply did not remove its ability to determine which business models could compete.
The judgment did not provide an extensively separate market analysis for an upstream airport-access service. Its reasoning concentrated on the unified downstream rental market and DAA’s exclusive practical control over entry to it. That distinction matters when assessing the decision’s application beyond airport infrastructure.
3.5 Why Procurement Compliance Was Not a Defence
The judgment distinguishes competition for concessions from competition within the rental market. An independently conducted tender may allocate concession rights lawfully without establishing that every subsequent restriction on other providers is lawful.
DAA relied on Directive 2014/23/EU and the European Union (Award of Concession Contracts) Regulations 2017. The court did not find collusion in the tendering process. Rather, it held that procurement obligations remained subject to the Treaties and did not extinguish continuing competition law duties.
Two features undermined the tender defence:
- The package did not match ER’s request. ER wanted customer transport access, not desks, vehicle spaces, and a full on-airport concession.
- Participation was commercially unrealistic. Evidence indicated that a successful smaller concession bidder might need to guarantee approximately €5 million annually, while ER’s entire gross turnover was approximately €5 million.
The court also considered the economic substance of equivalent transactions under Article 102(c). Formal contractual differences could not be decisive where the underlying issue was access to the same passenger base. Otherwise, a dominant undertaking could avoid scrutiny simply by bundling essential access with unwanted facilities.
The licence documents further weakened DAA’s position. Their definition of rental services encompassed customers being met at the airport and transported elsewhere to collect vehicles. They also expressly preserved DAA’s ability to appoint additional providers. Existing concessionaires therefore had neither a categorically on-airport-only model nor contractual exclusivity against new entrants.
The judgment did not, however, declare that ER must receive identical facilities or an identical fee. Its concern was functionally fair access, not the erasure of genuine differences between concession packages and limited transport permissions.
3.6 Why the Bronner Threshold Did Not Govern
Bronner imposes demanding conditions before competition law requires access to infrastructure developed by a dominant undertaking for its own business. The requested input must be indispensable, the refusal must threaten elimination of competition by the requesting undertaking, and objective justification must be absent.
DAA sought to make indispensability decisive: passengers could reach ER by taxi or public bus, so shuttle access was not essential. The High Court rejected that legal characterisation.
Drawing on telecommunications and digital-platform decisions, it identified a distinction between a pure refusal to share proprietary infrastructure and other exclusionary practices, including discriminatory conditions, unfair terms, and tying access to unwanted services.
DAA already made its infrastructure available to third-party rental businesses. ER’s complaint concerned the conditions on which it could reach customers and DAA’s insistence that it adopt the concession model. The court therefore treated the case as exclusionary gatekeeping rather than a straightforward compulsory-sharing claim.
Importantly, the rejection of the Bronner threshold did not itself establish abuse. The court also relied on the proven protective coordination, practical impairment of ER’s service, restrictive bundling, and absence of a sufficient objective justification.
The taxi and bus alternatives remained factually inferior. Evidence addressed inconvenient bus-stop locations, difficulty obtaining short taxi journeys, customer complaints, and the loss of a reliable, integrated transfer service. DAA’s own earlier affidavit evidence acknowledged that convenient connection between passengers and rental vehicles was integral to airport car hire.
3.7 The Single Till Model Did Not Justify Exclusion
Under single till regulation, anticipated commercial profits are taken into account when setting caps on aeronautical charges. DAA argued that high concession revenues ultimately benefited passengers through lower airport charges and justified its arrangements.
The court preferred evidence from ER’s regulatory expert, a former Commissioner for Aviation Regulation. The price cap was ordinarily fixed for five years. During that period, improved commercial performance could increase DAA’s retained profit without automatically reducing charges.
The agreed evidence nevertheless recognised that changes in rental profits would be expected to influence future price caps. The judgment should therefore not be read as denying every longer-term connection between commercial profits and airport charges. Its central conclusion was that there was no demonstrated, immediate pass-through and no regulatory obligation to exclude off-airport providers.
Neither expert had quantified the scale of the eventual effect on charges. DAA’s economist had also not assessed the consumer benefits of the incumbent-only arrangement or the benefits potentially available from a commercial agreement with ER.
A statutory duty to generate revenue was not a licence to suppress competition. Regulatory interest in commercial performance differed fundamentally from regulatory compulsion to adopt the challenged conduct.
3.8 Fair Procedures: A Separate and Unsuccessful Claim
ER argued that unsuccessful prosecutions deprived it of an opportunity to vindicate its good name. The court rejected that proposition. Dismissal or strike-out preserved the presumption of innocence; a prosecutor was not obliged to continue proceedings simply to provide a defendant with a public vindication.
DAA did not control the District Court’s adjudication. Questions about the interpretation of the bye-laws could be addressed through declaratory proceedings, while a refusal of permission could be challenged by judicial review. Article 106(1) TFEU did not provide a separate basis for attacking domestic criminal procedure.
The court also rejected arguments based on targeted enforcement, the incentive offer, and different treatment at Cork and Dublin Airports. Enforcement powers did not make DAA the adjudicator of criminal liability, and differences in airport size, infrastructure, traffic, and security could justify different operational responses. The Cork–Dublin issue also faced a pleading obstacle.
These conclusions do not mean that enforcement was commercially neutral. The same conduct could help prove anti-competitive coordination without establishing a separate procedural defect. Competition law and fair-procedures law asked different questions.
3.9 Delegated Legislation and Ultra Vires Bye-Laws
The court rejected ER’s suggestion that its shuttle operation was merely ancillary and therefore outside regulation 10. Transporting passengers was central to its off-airport business. The critical issue was instead whether the permission regime could lawfully be interpreted and applied to exclude that business model.
Article 15.2.1 of the Constitution reserves legislative authority to the Oireachtas. Delegated rule-making must operate within the principles, policies, and purposes of its parent legislation. The court considered section 15 broad, but refused to infer that it authorised DAA to suppress competition for the commercial benefit of concessionaires.
The statutory power had to be construed consistently with competition law, EU Treaty obligations, and the freedom to conduct a business recognised by Article 16 of the Charter of Fundamental Rights of the European Union. That freedom is qualified by law; it is not an unconditional entitlement to airport access.
The court concluded that, if DAA’s asserted interpretation were correct, the bye-laws were ultra vires because of their excessive anti-competitive reach. The final relief addressed the making of ultra vires and disproportionate bye-laws, not merely individual enforcement decisions.
A limit on the holding: The judgment did not declare section 15 itself unconstitutional. Nor did its concluding paragraph precisely identify the full extent of the provisions invalidated. The reasoning centres on the business-permission restrictions, particularly regulation 10, rather than demonstrating that the entire 2014 bye-law regime falls.
5. Impact and Limits
5.1 Concession Systems Remain Subject to Continuing Competition Duties
The judgment is important for airports and other infrastructure managers allocating commercial opportunities through concessions. Transparent procurement is not an immunity from scrutiny of later exclusionary arrangements. Operators should distinguish facilities genuinely required for a concession from access rights that alternative business models may need separately.
5.2 Incumbent Complaints Require Independent Evaluation
A facility manager may investigate genuine safety, congestion, licensing, or contractual concerns. The risk arises when complaints about lost revenue and aggressive pricing become coordinated demands to suppress a rival. Trade associations and concession managers should avoid converting regulatory enforcement into collective commercial protection.
5.3 Physical Gatekeepers Face Principles Developed in Platform Cases
The application of Android Auto and Google Shopping reasoning to airport access demonstrates that gatekeeping principles are not confined to digital markets. The relevant inquiry concerns the infrastructure’s purpose, existing third-party access, the nature of the challenged conduct, and its competitive consequences.
However, the judgment’s emphasis on DAA’s absence from downstream rental supply should not be converted into a universal rule that every non-integrated infrastructure owner must contract with every applicant. The underlying EU cases require a contextual examination; downstream non-participation alone does not establish abuse.
5.4 No Automatic Right to Free or Unregulated Access
ER sought a commercial arrangement, not free use of airport facilities. The judgment did not set a fee, allocate a particular stop, or prescribe contractual terms. Genuine, proportionate, and non-discriminatory safety and operational requirements remain permissible.
5.5 Liability Did Not Establish Quantified Loss
The court expressly found that ER had not proved, on the balance of probabilities, that its business would have been larger without DAA’s impediments. That finding does not negate competitive restriction, but it illustrates the distinction between establishing unlawful conduct and proving a particular counterfactual loss. No damages award appears in the supplied judgment.
5.6 The Declaratory Outcome Leaves Implementation Questions
The court’s expectation of lawful compliance explains its reluctance to add an injunction. Nevertheless, the judgment leaves the practical access arrangements and the precise reach of the bye-law declaration undeveloped. It also contains an internal inconsistency: paragraph 141 refers to the granting of an interlocutory injunction, whereas the agreed chronology records that such relief was refused. The decision should not be described as enforcing an earlier injunction.
