This Wednesday (10), the Federal Supreme Court (STF) judges appeals presented by platforms that operate social networks against the Court's decision that recognized the responsibility of big techs for illegal posts made by their users. The session is scheduled to start at 2pm.  The plenary will judge appeals requesting clarification on the Court's decision. The appeals were filed by Facebook and Google.  Related news: Decree determines that big techs must prevent criminal content. Lula warns about the risk of bets and big tech for families and democracy. Lula says that regulation of big techs avoids “lawless land” on the internet. The platforms' resources ask for a deadline for implementing the rules defined during the trial, or for the application of the rules to be guaranteed only after the plenary decision has become final.  The Supreme Court was also asked to recognize the relative presumption of guilt of the platforms, that is, to admit the possibility of presenting evidence to the contrary.   Accountability  In June last year, the STF ruled that Article 19 of the Marco Civil da Internet (Law 12,965/2014) was partially unconstitutional, a rule that established the rights and duties for using the internet in Brazil. The provision established that, "in order to ensure freedom of expression and prevent censorship", platforms could only be held responsible for their users' posts if, after a court order, they did not take measures to remove illegal content. Therefore, before the STF's decision, big techs did not respond civilly for illegal content, such as anti-democratic posts, messages containing hate speech and personal offenses, among others. The final text of the decision defined that Article 19 does not protect fundamental rights and democracy. Furthermore, until a new law on the issue is approved, providers will be subject to civil liability for user posts. According to the decision, platforms must remove the following types of illegal content after extrajudicial notification: undemocratic acts; terrorism; inducement to suicide and self-harm; incitement to discrimination based on race, religion, gender identity, homophobic and transphobic conduct; crimes against women and content that propagates hatred against women; child pornography; human trafficking. In case of non-compliance, the platforms must be held responsible for moral and material damages caused by users to third parties.
