BRASÍLIA, April 13, 2026 — Diogo Thomson de Andrade has assumed the role of acting president of Administrative Council for Economic Defense (Cade) as of April 12, following the end of the mandate of former president Gustavo Augusto.
Thomson, who has worked at the Brazilian antitrust authority for nearly two decades, is considered one of the institution’s most experienced officials, having served in multiple roles across its enforcement and decision-making structures.
Long career within CADE
Thomson first joined Cade in 2007 as a prosecutor. Over the years, he has worked in litigation, administrative investigations and management roles, eventually becoming deputy superintendent-general in 2012, a position he held for more than ten years.
During that period, he also served twice as acting superintendent-general, from July to October 2017 and from July 2021 to April 2022, overseeing the agency’s investigative arm during key moments for the authority.
In 2023, Thomson joined Cade’s Tribunal as a commissioner, completing a career that has spanned virtually all levels of the institution—from legal advocacy and investigations to adjudication.
Before joining Cade, Thomson worked at the Department of Economic Protection and Defense within Brazil’s Ministry of Justice and has been a federal attorney with the Advocacia-Geral da União since 2004.
Experience in major competition cases
During his time on the Tribunal, Thomson has been involved in several significant competition cases. In the field of anticompetitive conduct, he contributed to case law concerning price-setting practices by professional councils, including the CRECI/GO case.
He has also played a role in discussions on vertical restraints, notably in the Pirelli consultation case, and participated in the review of major merger transactions, including a deal involving TIM and Telefónica.
More recently, his decision in the Google News case positioned Cade within the broader international debate on regulation of digital platforms.
Academic background
Thomson holds a doctorate in law from the Instituto Brasiliense de Ensino, Desenvolvimento e Pesquisa and a master’s degree in philosophy of law from the Pontifical Catholic University of São Paulo.
His appointment as acting president follows nearly two decades of continuous work in Brazil’s competition enforcement system.
