Our Antitrust and Competition team provides advice and counseling to our clients in a wide variety of issues related to antitrust and competition law in Brazil, with a performance recognized both by clients and peers, and reflected in the most important rankings in the industry.

Great national and multinational companies in various industries entrust the Antitrust and Competition team at Tauil & Chequer with matters such as the notification of complex transactions for approval by CADE, ensuring the necessary agility for your business and expansion initiatives, as well as defending the interests of clients who wish to question the anticompetitive effects of transactions between third parties.

We also assist clients in investigations for violation of the economic order, such as in cartel cases. We format and conduct internal investigations to verify the existence of anticompetitive practices, as well as assist in mitigation measures and training programs. We represent clients in negotiating agreements with CADE, as well as in the investigations conducted by the authority, preparing defense strategies at the administrative and judicial levels. We provide consulting to industry associations to ensure the fulfillment of institutional missions in compliance with competition law, minimizing infringement risks. 

Our team represent clients in investigations of abusive conduct - both filing formal complaints with the authority as well as defending companies accused of such practices and developing strategies for litigation. At the consulting level, our team advises our clients on their day-to-day dealings, formatting distribution policies and assisting in negotiating business contracts in compliance with competition law, as well as creating training programs in competition law. We also assist large companies in navigating the decision spheres in regulated sectors, helping them to protect themselves from anticompetitive consequences of the regulatory activity.

Our team has substantial experience with the Brazilian authorities responsible for enforcing competition law. We are strategically located in Brasília – allowing for speedy contact with authorities and close to the decision-makers – as well as in São Paulo – fully available to promptly serve our clients with the necessary quality and agility.
