From February to May 2009, Jarosław Sroczyński conducted, as part of the pro bono activity of Markiewicz & Sroczyński, a Competition Law Workshop attended by a group of students of the Faculty of Law and Administration of the Jagiellonian University. The purpose of the workshop was to provide exercises in the drafting of an appeal against a hypothetical decision of the President of the Office of Competition and Consumer Protection, which was related to the conclusion of a prohibited agreement. During the workshop the participants carried out an analysis of relevant markets, prepared arguments concerning the alleged infringements of competition law and developed motions based on the evidence. A full draft appeal to be submitted by the addressee of the decision to the Court of Competition and Consumer Protection was drawn up.
