Price discrimination is one of the most common forms of dominant position abuse and infringements of Article 102 of the TFEU. As such, price discrimination is part of competition law, which has as its primary objective the protection of competition on the merits and indirectly, the protection of consumers. Competition, already weakened by the very existence of an undertaking in a dominant position, must be under the special supervision of control bodies that must prevent all abusive actions that can lead to imbalances in competition. Such actions lead to exploitative or exclusionary effects that affect competition and thus the welfare of consumers, the preservation of which is the main goal of competition law. Different forms of price discrimination will be analyzed through cases before EU institutions, either through decisions of the European Commission or through cases of the EU Court. The paper will also present the different viewpoints of the academic community related to the effects of price discrimination, the determination of abusive behavior itself, and the work and decisions of the competition control authorities. The work will, through several chapters, follow the steps that the control body must go through in order to sanction potentially abusive behavior. Likewise, concepts related to the abuse of a ruling position will be explained in more detail throughout the paper.
