Professor Robert Cryer was a foundational voice in modern international criminal law.This book celebrates his character, his life, his work, and his influence. The book is a Festschrift of love and admiration for a character that is dearly missed.Fittingly, the book also continues to voice the many conversations that Rob started.It thereby doubles as a critical examination of the life of international law. The book constellates 17 expertly-authored chapters nurtured by four editors through five distinctive sections, each of which reflects on the character of international law.These sections, presented as acts, are: discipline and borders, (re)imagination and continuity, violence and reckoning, acoustics and storytelling, and friendship and kindness. A wide gamut of touchpoints dovetails into a beautifully eclectic medley.These include criminal law, the law of war, music and harm, gender-based violence, nuclear weapons and artificial intelligence, law after war, the crime of aggression, drones and targets, the domestication of international law, and the role of law in inter-state relations.The book journeys to many places, including Japan, Bosnia and Ukraine, while reflecting on the role of teaching and mentorship in the life of international law.
