The purpose of this report is to analyze the judicial review of legislative and administrative acts in Brazil during the Covid-19 pandemic. Departing from the empirical evidence collected, it focuses on three main aspects: 1. The general characteristics of the judicial review of legislative and administrative acts during the pandemic; 2. The intensity of the judicial review, compared to before the pandemic; 3. Whether the pandemic has redesigned the role of the courts compared to before the pandemic. The framework is the Brazilian constitutional court, Supremo Tribunal Federal, and its rulings regarding the competencies of the three levels of the Brazilian federation, federal, state and municipal. The sources are legislative and administrative acts published in the official gazettes of the federal, state, and local governments and the official website of the Supremo Tribunal Federal. Regarding the political declarations and events related to the coronavirus outbreak, the source is the newspaper Folha de S. Paulo. Through an applied research methodology, using qualitative and quantitative analysis, this report will present conclusions regarding the role played by the Constitutional Court in the redesign of Brazilian federative system during the Covid-19 pandemic.
