Artistic censorship has been constant in brazilian history, until its formal extincion after 1988 Constitution. Although previous censorship is prohibited, works of art have been submited to the constitutional Powers, since then, in order to determine the limits of artistic freedom of expression. In september 2017, four episodes of censorship occurred in the same month and became notorious all over Brazil, specially the Queermuseu exhibition and the performance La Bête. This cases are the starting point to this research. This four episodes unleashed a conservative turning point in the behaviour of the institutions and the public debate concerning freedom of speech. In order to analyze this change, case studies will be carried out, comparing the most notorious episodes of the period. The time frame has been restricted from the cases Queermuseu and La Bête, that took place in september, 2017, until the closure of cultural spaces during the COVID-19 pandemic, in march 2020. This paper approaches the peculiarities of censorship in this time frame, featuring the tendency to deny itself. Also, this research will expose some of the legal and administrative tools available to the artists and the citizens to fight censorship by constituted Powers.
