Antitrust and Regulated Markets

We focus on understanding our clients’ business to help them operate competitively, prevent contingencies, and protect corporate reputation.

Our experienced team advises and represents companies, institutions, and individuals in antitrust matters, including abuse of dominant position and collusion cases. We have participated in some of the most notable cases in the country, representing clients before the Competition Tribunal and the National Economic Prosecutor’s Office. We also represent clients in judicial and out-of-court matters to ensure compliance with antitrust regulations and prevent market distortions.
