How can international humanitarian law (IHL) be implemented and enforced? International criminal law (ICL) plays an important role in this respect, placing responsibility on individual persons for serious atrocities including genocide, war crimes, crimes against humanity, and the crime of aggression.

On 29 September, PHAP members and guests had the opportunity to delve into this topic with Chris Jenks, a law professor with previous experience in the U.S. Army and the co-editor of a forthcoming war crimes casebook. The session began with a briefing on ICL and its relevance to humanitarian actors, focusing on its core principles, main instruments, scope of application, and relationship with IHL. This was followed by an opportunity for Q&A and discussion.
