The success of different categories of legal professionals in building positions of state power in Brazil since the end of the military regime is in line with the legitimation of models of law and international cooperation. This article focuses on the connections between Brazilian legal actors and the international ‘fight against corruption’. By looking at the international connections of Brazil’s Public Prosecutor’s Office (MPF), we aim to show how the promotion of anti-corruption models of law is the result of corporate cooperation strategies. We cite as evidence overseas travel by MPF agents and their connections with the international field in recent decades. We start by analyzing cooperation documents and then attempt to trace the MPF’s pathway towards internationalization during the 2000s
