About us

Justen, Pereira, Oliveira & Talamini is a leading Brazilian law firm in the fields of infrastructure, regulated services and public procurement. It provides expert legal services to private enterprises and government entities, with a special focus on government contracts, concessions and administrative and regulatory law.

The firm was created by Marçal Justen Filho in 1986. Today it has twenty lawyers in its three offices in São Paulo, Brasília and Curitiba. 

In the past fifteen years, the firm has been involved in many of the most relevant and financially significant government-related contracts and transactions in Brazil, either as counsel to participants or as expert advisor to private parties or to the government.

Arbitration and other ADR methods are one of the firm’s main areas of activities. The firm is active in representing parties in arbitration and some of the partners are frequently appointed as arbitrators in international or domestic arbitrations and belong to the directive or consulting boards of arbitration centers.

The firm is based on a strong academic background – all four senior partners hold PhD degrees in their areas and are respected legal authors, with more than twenty books and numerous articles and essays published in Brazil and abroad – and a commitment to excellence and expertise. An important portion of the firm’s business involves the provision of expert legal opinions by Marçal Justen Filho and Eduardo Talamini, partners of the firm and internationally recognized scholars in their respective areas of public law and civil procedure.
