This Glossary has been prepared by DG COMP for non-competition specialists. Each term is enriched with references of national case laws from the e-Competitions Bulletin.

Abuse of a dominant position

Anti-competitive business practices (including improper exploitation of customers or exclusion of competitors) in which a dominant firm may engage in order to maintain or increase its position on the market. Competition Law prohibits such behaviour, as it damages true competition between firms, exploits consumers, and makes it unnecessary for the dominant undertaking to compete with other firms on the merits. Article 102 of the Treaty on the Functioning of the EU lists some examples of abuse, namely unfair pricing, restriction of production output and imposing discriminatory or unnecessary terms in dealings with trading partners.
