Horizontal agreement meaning

What does Horizontal agreement mean?
A horizontal agreement is an arrangement between businesses at the same level of the supply chain—usually actual or potential competitors—covering matters such as pricing, market allocation, output, information exchange, joint purchasing, joint production/specialisation, research and development, or standardisation. In competition law, the concept is used consistently across England & Wales, Scotland, Northern Ireland and Ireland, and is reflected in guidance from the UK Competition and Markets Authority (CMA) and the European Commission’s Horizontal Guidelines (applicable in Ireland). It is not a statutory term of art but a widely accepted descriptive category. Legal significance: under the Chapter I prohibition in the Competition Act 1998 (UK) and section 4 of the Competition Act 2002 (Ireland), and under Article 101 TFEU (relevant in Ireland and to agreements with effects within the EU), horizontal agreements that amount to cartels—such as price-fixing, bid-rigging, market-sharing or output limitation—are typically restrictions “by object”, presumptively unlawful and subject to heavy fines, potential criminal liability and (in the UK) director disqualification. Other forms of cooperation can be lawful where they meet block exemption conditions (e.g. R&D or specialisation) or qualify for individual exemption based on demonstrable efficiencies, indispensability and preservation of residual competition. Robust compliance and controls on competitively sensitive information...

EWHC implies horizontal arbitration agreement between FA Participants; section 9 stay granted in Alrubie v Chelsea FC, despite director ceasing office

Alrubie v Chelsea Football Club Ltd and another [2025] EWHC 541 (Comm) What are the practical implications of this case? This decision will particularly interest arbitration practitioners and professionals working in sports clubs, and could equally concern other organisations whose members are controlled by association rules. Commonly, those participating in professional sports clubs accept, by reason of their membership, that they are bound by the club’s rulebook and by the regulations of any national and worldwide governing bodies. Such regimes routinely incorporate arbitration agreements, owing in part to the confidentiality of arbitral proceedings, which protects against undesirable public attention, and in part to the ability to appoint arbitrators with specialist knowledge of the sport’s rules and industry practices. The case clarifies that these rules may have ‘horizontal’ contractual effect between members, as well as ‘vertical’ effect between each member and the governing body, notwithstanding the absence of any express bilateral agreement between members. It underlines how membership-based governance can, through the acceptance of rulebooks, generate binding obligations that...

EU competition law: first informal guidance on sustainability - Commission comfort letter on joint procurement and charging standards for electric port equipment clarifies safeguards and signals openness to industry-led decarbonisation

The European Commission (the Commission) has, for the first time, sent informal guidance letters relying on its updated 2022 Notice on Informal Guidance (the 2022 notice). The letters examine how sustainability principles apply to co-operation arrangements in the transport industry. Beyond being the inaugural letters issued under the previously little-used 2022 notice, the APM comfort letter is also the first occasion on which the Commission has applied the 2023 revised Guidelines on Horizontal Co-operation Agreements (the 2023 guidelines) to a sustainability initiative. Sustainability agreements are described as 'any horizontal co-operation agreement that pursues a sustainability objective, irrespective of the form of the co-operation'. The 2023 guidelines openly permit sustainability agreements that may raise competition issues provided they deliver verifiable efficiency gains, are necessary to secure those efficiencies, confer benefits on consumers, and do not eliminate competition. Background: Informal Guidance and Sustainability In 2004, the EU overhauled its competition law enforcement framework and processes, shifting from a centralised notification and authorisation regime for agreements between undertakings to a self-assessment...

EU Specialisation Block Exemption Regulation 2023/1067: Article 101 TFEU safe harbour: scope, market-share threshold, duration, hardcore restrictions, transitional arrangements, and withdrawal

Introduction Block exemption regimes provide widely applicable safe harbours from the EU prohibition on anticompetitive agreements as set out in Article 101(1) TFEU, so long as the arrangement satisfies the requirements of the relevant block exemption. Each such instrument rests on the presumption that any restrictive deal within its compass fulfils the four criteria in Article 101(3) TFEU that are needed for an individual exemption from the application of Article 101(1) TFEU (see further, Article 101(1) TFEU—the prohibition on restrictive agreements and Individual exemptions under Article 101(3) TFEU). Accordingly, every block exemption establishes a safe harbour that shields restrictive arrangements from legal challenge under Article 101 TFEU. The former Specialisation Block Exemption Regulation (EU) 1218/2010 (SBER 2010), which expired on 30 June 2023, had been in force since 1 January 2011. Following a review process and consultation with stakeholders, the updated Specialisation Block Exemption Regulation (EU) 2023 (SBER 2023) entered into force on 1 July 2023. Specialisation agreements are most likely to contribute to improvements in manufacturing or the...

Competition law compliance: staff handbook on cartels, dominance, horizontal and vertical agreements, red flags, competitor meetings, trade associations, intelligence gathering, penalties and reporting

Question Summary What is competition law? Competition serves both consumers and companies. It highlights areas for improvement and pushes organisations to pursue higher efficiency, greater innovation, stronger productivity and, in the end, to operate as better businesses. Competition law exists to shield businesses and consumers from anti‑competitive conduct and to preserve effective rivalry. Every business must observe competition rules, and breaches can carry severe outcomes for firms and individuals, including directors. Non‑compliance can be costly and damaging at both organisational and personal levels too. Possible penalties include: Substantial fines Prison sentences Director disqualification Damage to reputation When is it an issue? Competition law can arise in three principal settings: cartels — typically horizontal arrangements in which two or more businesses, whether by written agreement or otherwise, decide not to compete with one another. Cartels are the gravest form of anti‑competitive agreement. They cover accords to fix prices, rig bids, cap output, and divide customers or markets. A cartel...
