Dentons

Competition

Maciej Marek has practiced competition law for over ten years. He advises on M&A transactions, represents clients before antitrust authorities and assists in implementing compliance programs.

Maciej has advised Polish and multinational leaders operating in the sectors of IT, media, telecommunications, FMCG, as well as trade and distribution, including many Fortune Global 500 companies. He has represented clients and participated in numerous proceedings before the Polish competition authority, the European Commission as well as Polish and EU courts.

His experience includes negotiating what was probably the most complex conditional merger clearance the Polish competition authority has ever issued (a tiered, mixed, structural-behavioral remedy) as well as advising on unfair competition aspects of the biggest domestic dispute over a brand. He regularly handles multijurisdictional projects, including those requiring coordination of work of multiple local lawyers, economists and IT providers.
