This brief analyses the impact of the Christchurch Call to Action, issued to gather countries and technology companies to stop the use of the internet for disseminating violent extremist content. The Call was the result of a summit organised shortly after a terrorist attack in New Zealand in March 2019. This brief finds that the Call lacks clear conceptual definitions and is singularly focused on social media platforms. It also raises questions about how such efforts can maintain a balance between safeguarding digital platforms against terrorist and violent content, while preserving essential freedoms including of speech and expression.
