Speech has become an increasingly central feature of international criminal proceedings, particularly in cases involving senior political or military leaders. The PJI Guidelines are grounded in extensive jurisprudence, empirical research, and scholarly analysis, drawing on decisions from international courts and tribunals as well as broader interdisciplinary insights. Anchored on the fundamental right to freedom of expression, the Guidelines conveys guidelines for securing criminal accountability. In doing so, the book addresses cutting edge issues including disinformation, interpretation, social media, and AI propagated inflammatory and hateful speech, among other topics. It proposes 10 Key Guidelines, including an amendment to Article 25(3)(e) to criminalise intentional, direct and public incitement to any atrocity crime under the Rome Statute.
