This article discusses the participation of civil society during the governments of President Lula, particularly in institutional public spaces. The participation of civil society in decision-making processes, incorporated in the Brazilian Constitution of 1988, has been a central principle in the political project of the Partido dos Trabalhadores (PT) since its foundation in 1980. This paper examines the extent to which this principle has remained effective and has been actively implemented at the federal level since the PT came to power in 2002. It also analyzes the concrete results of implementing greater participation and the difficulties faced in doing so. In addition, it explores both the continuities and new developments that have emerged during the government of Lula’s successor, Dilma Rousseff.
