Competition law meaning

What does Competition law mean?
Competition law describes the body of antitrust rules that govern business conduct which restricts competition and the review of mergers and acquisitions. In practice it addresses anti‑competitive agreements (cartels and concerted practices), abuse of dominance, merger control and enforcement. It is a descriptive term rather than a single defined concept, and draws on statute, guidance and case law. United Kingdom (England & Wales, Scotland and Northern Ireland): the principal rules are the chapter i and Chapter II prohibitions in the Competition Act 1998, and the Enterprise Act 2002 regime for merger control and the criminal cartel offence (Part 6). The Competition and Markets Authority (and sectoral regulators) enforce these rules, with appeals to the Competition Appeal Tribunal. After Brexit, Articles 101 and 102 TFEU and the EU Merger Regulation no longer apply directly in the UK, but may apply to UK conduct with EU effects; section 60A CA 1998 informs reliance on EU jurisprudence. Ireland: the Competition Act 2002 (as amended, including by the Competition and Consumer Protection Act 2014 and Competition (Amendment) Act 2022) and EU law (Articles 101 and 102 TFEU and the EU Merger Regulation) apply, enforced by the CCPC. Usage is broadly consistent across these jurisdictions.

Global merger control: jurisdictions requiring notification of non-controlling minority shareholdings (checklist and thresholds)

Non-controlling minority shareholdings This Checklist identifies the jurisdictions worldwide where acquisitions of non‑controlling minority shareholdings must be notified, provided the other jurisdictional thresholds are satisfied. In this context, ‘non‑controlling minority shareholdings’ means any degree of influence falling short of what the EU Merger Regulation terms ‘decisive influence’—namely, the capacity to exercise a significant level of control over an undertaking’s strategic commercial behaviour. That influence can be exercised through a variety of routes, including share ownership, voting rights (in particular, veto rights), or contractual arrangements, and does not necessarily involve holding a majority shareholding...

Herfindahl–Hirschman Index (HHI) in merger control: calculation, examples, thresholds, delta interpretation and red flags—practical checklist for competition lawyers

To gauge concentration within a particular market, competition authorities often turn to the Herfindahl‑Hirschman Index (HHI) as a primary tool that supports and streamlines their assessment. Although the absolute HHI level provides an early signal of post‑merger competitive pressure, the movement in the HHI (the ‘delta’) functions as a practical proxy for the change in concentration directly attributable to the merger itself and its immediate effects. How to calculate the HHI The HHI is obtained by adding the squares of the individual market shares of all firms participating in the market, without omitting any active competitor...

Practical checklist for coordinating multi‑jurisdictional merger control filings: transaction scope, thresholds, timetables, standstill obligations, notifications, remedies, fees, confidentiality, substantive assessment, post‑completion filings, other approvals, and appeals

More than 150 jurisdictions operate merger control, or regimes akin to it. Within these systems, competition regulators may prohibit a deal entirely, or approve it subject to remedies, whether agreed or imposed. This Checklist sets out practical points to bear in mind when managing filing obligations across multiple jurisdictions. For overviews of merger control rules in every jurisdiction, see MJ merger grid—jurisdiction and MJ merger grid—procedure. For distilled takeaways, consult Key learning points from MJ reviews—anomalies, absurdities and potential pitfalls. It also flags issues commonly seen in practice. Guidance is provided in those resources. What transactions fall within merger control rules? Relevant transactions Across most regimes, including the EU, merger control captures any deal that places formerly independent undertakings under common control. Control is often defined broadly. Acquisitions of control—sole v joint control Control can rest with a single party, or be shared with one or more others: sole control: a shareholder that acquires control can take strategic decisions for the target without...

EU General Court upholds Commission’s re-adopted decision on retail food packaging trays cartel: CCPL v Commission—parental liability, 10% cap per infringement and inability-to-pay rejected

CASE HUB ARCHIVED This archived case hub reflects the position as at the judgment of 7 December 2022; it is no longer maintained. See further, timeline. Case facts Outline Appeal before the General Court seeking annulment of the Commission’s readopted infringement decision of 17 December 2020, which imposed a reduced fine amounting to €9.4m (AT.39563). Latest development On 7 December 2022, the General Court delivered its judgment and dismissed the appeal in full. In particular, it found that: (i) CCPL grasped the Commission’s reasoning, and the material presented by CCPL was insufficient to overturn the presumption applied by the Commission that CCPL exercised decisive influence over entities within the CCPL group; and (iii) the Commission did not err in concluding that a fine reduction can only be warranted by the aim of preventing the undertaking’s economic viability from being irreparably endangered and its assets stripped of value, so the applicant’s intention to develop operating companies of the CCPL group cannot, in principle, justify such...

Global merger control: threshold updates, procedural reforms and enforcement highlights—March 2026

Over the course of the past month, annual adjustments have been made to merger control thresholds in Canada, Italy and the Philippines, while Montenegro has revamped its regime, introducing swifter timetables and more adaptable filing provisions.

Does a paid-entry prize draw app constitute a lottery?

For this Q&A, our review is confined to how lotteries, competitions and prize draws differ. Our analysis has focused specifically on distinguishing among these three mechanisms. Definitions The meaning of 'prize competition' Under the Gambling Act 2005 (GA 2005), a ‘prize competition’ means any contest or arrangement in which a participant may secure a prize, so long as it does not fall within the statutory concept of gambling. The meaning of 'gambling' English law recognises three principal forms of gambling: betting, gaming and lotteries. While the statutory tests are intricate, they can be outlined in broad terms as follows: Betting involves making or accepting a wager on the result of a race, competition or other event or process, on the likelihood of something occurring or not occurring, or on whether a proposition is true or false (even where one party knows the facts). Although ‘bet’ is not expressly defined in legislation, case law commonly characterises it as risking something of value on...

Are s106 TCPA contributions caught by State aid rules or exempt?

State Aid: The Basics Guide The Department for Business, Innovation & Skills’ July 2015 guide, State Aid: The Basics Guide, explains that state aid arises wherever public resources are used to give organisations an edge over others, potentially distorting competition and harming consumers and businesses across the EU. The concept is deliberately wide, as an “advantage” can be delivered in many ways, for example: grants loans tax breaks the use or sale of a state asset free of charge or for less than market value Public authorities, including local authorities in England and Wales, are accountable for ensuring their policies and projects comply with these requirements. During the implementation period following Brexit, state aid rules continue to apply in the UK. The annex to the Department for Education’s November 2019 publication, Securing Developer Contributions for Education, notes that unlawful state aid can occur in relation to developer contributions towards education...
