Bomchil has strong credentials for competition and antitrust mandates, regularly assisting with cartel and conduct investigations, regulatory disputes, and the competition aspects of M&As and other transactions. The practice is led by Marcelo den Toom, who steers clients through sensitive investigations and internal audits, as well as handling merger filings and regulatory disputes before Argentina’s competition authority. Francisco Gutiérrez and Cristian Galansky contribute experience in complex regulatory matters, while Fernando Brunelli regularly assists with competition issues arising from corporate acquisitions, bidding rounds and investment structures. Identified as having a 'promising future', young associate Ilan Soae participates in merger control proceedings and investigations and also advises on anticorruption rules.
