Sean Ennis Price Abuses: An overview of EU and national case law

1238

Allegations of pricing abuses have tested the boundaries of competition law for more than a century and remain an important activity for many competition authorities and courts. While pricing abuses constituted key parts of some early antitrust case, many commentators have urged that they are best addressed outside competition law. Since the 1970s such matters have been addressed at the European Union level by competition law. Pricing abuses can be viewed as a hybrid between regulation and competition law enforcement, sometimes raising a question of principle over when pricing that takes advantage of market power should be prevented by competition law action, by regulation or simply left unchallenged.
