The article paints a picture of EU and national competition law being applied since Poland’s accession to the Community/European Union. As a matter of principle, the article presents legal and axiological arguments for the obligation of the pro-EU interpretation of national law applicable either jointly or independently of the EU competition rules. It proceeds to conclude that the maintenance of formally separate competition rules at the national and EU levels, after a period of intensive parallel application and fundamental convergence, has lost or will soon lose its raison d’être.
