About

Provided by Magalhães e Dias

Antitrust/Competition:
The firm has a proven track record in securing or challenging clearance in Brazil for the most complex mergers, acquisitions, and joint ventures of recent years. Magalhães e Dias’ attorneys have extensive experience with cartel and restrictive practice investigations by Brazilian antitrust authorities, advising both parties and interveners.


The firm is responsible for a substantial number of cease and desist agreements signed with CADE, including the first administrative cease and desist agreement involving cartel practices (cement sector) under Article 53 of Law 8.884/94 (former Brazilian antitrust law).

The firm is a pioneer and a leading player in conducting cases before courts concerning complex competition law cases, class actions, and advising clients on appeals against decisions from CADE, Regulatory Agencies or State or Federal Prosecutors. The increase of Brazilian investigations by antitrust authorities and regulatory agencies of possible cartels and restrictive practices indicates that appeals to the Judiciary related to competition law is already a reality in Brazil. The firm also has an extensive experience advising corporations in antitrust compliance programs, audits and internal investigations for clients, which includes the most traditional Brazilian associations.
