The UNESCO Guide for Amicus Curiae Interventions on Freedom of Expression Cases, developed with the support of Media Defence, seeks to equip civil society organizations with the basic tools to file effective amicus curiae interventions, and encourage them to intervene in cases where freedom of expression standards can be advanced or where the right to freedom of expression or the safety of journalists is at stake. The Guide provides practical information on how to file amicus curiae briefs and sets out strategic considerations – as well as do’s and don’ts – with the goal of helping organizations write the most impactful brief possible.
