The study analyses the provisions of article 10 of the European Convention of Human Rights, which protects freedom of expression, in the context of the Internet society.
Recent landmark ECHR and ECJ judgments, useful to explain the peculiar mechanism of protection of freedom of expression in the field, are examined in the text.
A special attention is given to the ECHR Grand Chamber Delfi v. Estonia judgment, delivered in 2015, which clearly set the position of the Information service providers, their powers and duties to filter and block illegal data, and their responsibility for defamation brought by Internet users.
