The production and dissemination of fake news has occupied a central place in current discussions about the degradation or erosion of democratic regimes. The current argument is that we live an unprecedented context in which fake news is produced and spread without controls or filters, contaminating the integrity of electoral processes and political competition. Inserted in this debate, this article seeks to discover and analyze what have been the responses of the Legislative and Judicial Branches have presented to combat the production and dissemination of fake news. To this end, we analyzed the bills proposed in the Legislature between 2017 and 2020 and also the decisions issued by the Superior Electoral Court regarding the 2018 and 2020 elections. Our analysis points out that state responses to fake news tend to be case-by-case, evasive and repressive, devoid of concerns to prevent the problem or adopt systemic solutions. Therefore, we concluded that the legal system is vulnerable to political attacks based on manipulation and distortion of facts, and the problem tends to worsen in upcoming elections.
