This guide prepared by Peter Noorlander for UNESCO offers “practical information and guidance to civil society organisations considering intervening in cases before national or international courts as so-called ‘amicus curiae’ or ‘third party intervener’. It is focused on interventions concerning freedom of expression and the safety of journalists." While the focus is on freedom of expression cases, the principles could be applied to human rights cases more broadly. The guide consists of six sections covering the most important aspects of preparing interventions, such as strategic consideration and technical requirements, recommendations on how to monitor cases and communicate with parties, and examples in the form of case studies.
