EU Competition Law Framework: Articles 101–102 TFEU and Merger Control
EU competition law is the framework of rules prohibiting anticompetitive conduct and ensuring the proper functioning of the internal market. The primary substantive provisions are Article 101 TFEU (prohibition of anticompetitive agreements), Article 102 TFEU (prohibition of abuse of a dominant position), and the EU Merger Control Regulation (Regulation 139/2004). Together with state aid rules under Articles 107–109 TFEU, these provisions form the competition pillar of the EU legal order, enforced primarily by the European Commission. EU competition law is one of the most influential competition law regimes globally, serving as a model for over 130 jurisdictions worldwide.
Article 101 TFEU: Anticompetitive Agreements
Article 101(1) TFEU prohibits all agreements between undertakings, decisions by associations of undertakings, and concerted practices which may affect trade between Member States and which have as their object or effect the prevention, restriction, or distortion of competition within the internal market. The prohibition covers both horizontal agreements between competitors and vertical agreements between undertakings at different levels of the production or distribution chain.
The provision lists specific examples of prohibited conduct, including: directly or indirectly fixing purchase or selling prices; limiting or controlling production, markets, technical development, or investment; sharing markets or sources of supply; applying dissimilar conditions to equivalent transactions with other trading parties, thereby placing them at a competitive disadvantage; and making the conclusion of contracts subject to acceptance of supplementary obligations having no connection with the subject of the contracts. The list is illustrative, and the CJEU has applied Article 101 to a wide range of restrictive practices.
An agreement infringes Article 101(1) if it has as its object or effect the restriction of competition. The object/effect distinction is critical: if an agreement has an anticompetitive object — meaning it is by its very nature capable of restricting competition — there is no need to prove anticompetitive effects. Hardcore cartels, including price fixing, market sharing, output limitation, and bid rigging, are treated as object restrictions. For non-hardcore restrictions, the Commission must demonstrate actual or potential anticompetitive effects, typically through economic analysis of market conditions.
Article 101(3) provides an exemption for agreements that contribute to improving the production or distribution of goods or to promoting technical or economic progress, while allowing consumers a fair share of the resulting benefit, provided the restrictions are indispensable and do not eliminate competition in respect of a substantial part of the products. The Modernisation Regulation (Regulation 1/2003) abolished the prior notification system and made Article 101(3) directly applicable by national courts and competition authorities, creating a system of parallel enforcement.
Article 102 TFEU: Abuse of Dominance
Article 102 TFEU prohibits any abuse by one or more undertakings of a dominant position within the internal market or in a substantial part of it, insofar as it may affect trade between Member States. Unlike Article 101, which prohibits the conclusion of restrictive agreements, Article 102 targets unilateral conduct by dominant firms that distorts competition. The prohibition does not condemn dominance itself — firms may achieve market power through legitimate competitive success — but rather the abusive exploitation of that dominance.
The assessment of dominance requires definition of the relevant market in its product and geographic dimensions, followed by evaluation of market power. The Commission applies the principles set out in its Notice on the Definition of the Relevant Market. An undertaking is dominant if it possesses economic strength enabling it to prevent effective competition being maintained on the relevant market and to behave to an appreciable extent independently of its competitors, customers, and ultimately consumers. Market shares exceeding 50 per cent create a presumption of dominance; shares above 40 per cent may indicate dominance depending on market conditions; shares below 25 per cent are unlikely to indicate dominance.
Article 102 lists examples of abuse: directly or indirectly imposing unfair purchase or selling prices or unfair trading conditions; limiting production, markets, or technical development to the prejudice of consumers; applying dissimilar conditions to equivalent transactions; and making contracts subject to supplementary obligations. The CJEU has recognised additional forms of abuse including predatory pricing (AKZO, Case C-62/86), margin squeeze (Deutsche Telekom, Case C-280/08 P), refusal to supply (IMS Health, Case C-418/01), tying and bundling (Microsoft, Case T-201/04), and exclusive dealing (Hoffmann-La Roche, Case 85/76). The modern enforcement approach, articulated in the Commission’s Guidance on Enforcement Priorities (2009), emphasises consumer welfare effects and economic analysis of foreclosure, particularly in the digital economy.
Merger Control Regulation
The EU Merger Control Regulation (Regulation 139/2004, the EUMR) establishes a system of mandatory prior notification and approval for concentrations with an EU dimension. A concentration arises where a change of control on a lasting basis results from the merger of two or more previously independent undertakings, or the acquisition of direct or indirect control of one or more undertakings. Concentrations with an EU dimension — defined by turnover thresholds reflecting the parties’ aggregate worldwide turnover and individual EU-wide turnover — must be notified to the Commission before implementation.
The Commission assesses whether a concentration would significantly impede effective competition (SIEC test) in the internal market, particularly through the creation or strengthening of a dominant position. The SIEC test, introduced by the 2004 revision, is broader than the previous dominance test, capturing non-collusive oligopolistic coordination and unilateral effects in markets without dominance. The Commission may prohibit a concentration, approve it unconditionally, or approve it subject to remedies — typically structural divestitures, behavioural commitments, or a combination of both.
The EUMR establishes a one-stop-shop principle: concentrations with an EU dimension are examined exclusively by the Commission, not by national competition authorities, unless a Member State requests referral under Article 9 or the parties request referral under Article 4(4). This system provides legal certainty and avoids multiple filings, particularly important for cross-border transactions. The Commission examines concentrations in two phases: Phase I (25 working days) for initial assessment, and Phase II (90 working days) for in-depth investigation of potentially problematic cases.
Enforcement by the Commission
The European Commission is the primary enforcer of EU competition law. Regulation 1/2003 confers extensive investigative powers, including requests for information, inspections of business and non-business premises (dawn raids), and interviews. The Commission may adopt decisions finding and ordering the termination of infringements, imposing interim measures, accepting commitments, and fining undertakings.
Fines under Article 23 of Regulation 1/2003 may be up to 10 per cent of the undertaking’s total annual worldwide turnover. The Commission’s 2006 Fining Guidelines set out a methodology based on the value of sales, the duration of the infringement, and adjustments for aggravating or mitigating circumstances. The Leniency Notice (2006) encourages cartel participants to self-report by offering immunity from fines to the first undertaking that provides sufficient information, and reductions to subsequent cooperators. The Settlement Notice (2008) enables cartel participants to admit participation and liability in return for a 10 per cent fine reduction.
National competition authorities and national courts apply Articles 101 and 102 TFEU in parallel with the Commission under Regulation 1/2003. The European Competition Network (ECN) facilitates cooperation and information exchange among competition authorities. National courts may award damages for competition law infringements, with Directive 2014/104/EU facilitating private enforcement by removing obstacles to damages actions and introducing rebuttable presumptions of harm from cartels.
