The event will be in English and Portuguese with simultaneous interpretation.

Due to the massive use of the internet as a vehicle for the exercise of freedom of expression, resulting in a large number of judicial processes on it in Brazil, and the actual difficulty in implementing effective protection of freedom of expression and at the same time guaranteeing safeguard to other rights that have the same level of constitutional and legal protection, the course objective is to study the current academic and judicial trends on the mentioned subject, nationally and internationally, to assist legal operators in the task of solving the practical problems that have emerged.

In terms of content moderation of hate speech, political issues, defamation and disinformation there are reasonable concerns about when and how certain discourses can be taken down without perishing the legitimate exercise of freedom expression and the convenience of giving such a powerful toll to private actors, the Internet intermediaries, especially social media.

Researcher at Max Planck Institute Erik Tuchtfeld and judge of São Paulo Court of Justice Fernando Henrique de Oliveira Biolcati-PhD will discuss how the power of social media over content moderation impacts the legal and judicial understanding about what is lawful or not in terms of legitimate exercise of freedom of expression and how the legal system can balance the power of intermediaries in shaping the public discussion.
