Baker McKenzie is especially effective where antitrust issues intersect with broader regulatory frameworks, including public law, trade, consumer protection and M&A. Spearheading the practice is Esteban Rópolo, who handles merger control, cartel defence, abuse of dominance and antitrust compliance mandates for a broad range of clients, particularly those across the bioscience, agribusiness, consumer goods and technology sectors. Key associates support is provided by Gonzalo Vazquez, who advises on merger control filings, cartel investigations, corporate structuring and business transactions; and Victoria Acevedo Freixas, whose practice takes in matters involving unfair trade practices, anti-dumping issues, and regulated markets.
