Enabling freedom of expression in light of filtering measures imposed on Internet intermediaries: Squaring the circle?

This study considers the scope of the injunction a court may issue against an intermediary service provider with a view to preventing or terminating an infringement, particularly of an intellectual property right. The matter is studied in the light of the aim shared by the European Union and the Council of Europe to promote freedom of expression via communication networks. Despite technological progress and the emergence of software that are increasingly precise and ever better controlled in terms of their effects, implementation of a filtering measure appears difficult to reconcile with the right to freedom of expression. Consequently, the problematic comes down to this question: how do we do enough without doing too much?
