The International League of Competition Law (LIDC) is a long standing association which focuses on the study of competition (antitrust) law, intellectual property law and unfair competition, both at the national and international levels. It promotes mainly the principles of fairness and justice in competitive trade. 

At the Budapest Congress, which took place in October 4-7 October 2018, the League has elected the New President, Carmen Verdonck (Belgium), the First Vice-President, Christophe Rapin (Switzerland), two Vice-Presidents, Zoltan Barakonyi (Hungary) and Muriel Chagny (France).
