Lawyer Rankings

Brazil > Competition and antitrust

TozziniFreire Advogadosremains one of the great references in Brazil when it comes to high-end corporate law firms‘. In competition and antitrust, the firm has established an impressive track record in the negotiation of leniency agreements with CADE, an area in which it maintains a large market share. The practice can also be seen representing companies in cartel and unilateral conduct investigations, and merger filings. Other distinguishing features include the team’s experience at CADE, with several of its lawyers having previously worked at the authority. Beyond the core competition group, the firm is also able to deploy cross-practice teams to cover the interconnected antitrust, compliance and white-collar criminal law aspects of complex cases. Tatiana Lins Cruz and Patricia Bandouk Carvalho are highlighted for their ability ‘to engage and dialogue with relevant authorities in this area at a high level‘. The well-regarded Marcelo Calliari leads the ‘highly qualified‘ team, which also includes Vivian Fraga, who is also a member of the firm’s Asia desk and as such acts for a number of Chinese, Korean and Japanese clients; Guilherme Ribas; and Marcel Medon Santos.
