This chapter examines the transposition of the Antitrust Damages Directive in Hungary. It begins with an overview of the transposition procedure, focusing on the Hungarian private enforcement landscape and the transposition process. In particular, it considers how the provisions implementing the Directive were built into the Hungarian Competition Act (HCA), creating a special regime that departs in certain aspects from the general principles of Hungarian civil law and civil procedure (e.g., access rules, calculation of damages). The chapter goes on to discuss the scope of the Hungarian implementing provisions as well as specific issues that arose during the transposition, including those relating to time-barring deadlines, binding force of decisions of other Member States, parent company liability, presumption and quantification of damages by cartels or other antitrust infringements, distribution of liability between co-infringers and right of return between co-infringers, access rules, collective redress, and organization of the judicial system.
