The document discusses the retroactivity of the International Criminal Tribunal Act (ICTA) in Bangladesh, addressing concerns about its compliance with legal principles regarding non-retroactivity in criminal law. Notable figures such as Ambassador Stephen Rapp raised questions about the legality of trying crimes committed in 1971 under a law created in 2010, but the text argues that such retroactive measures are consistent with international legal practices for heinous crimes. It emphasizes that the ICTA aligns with Article 15(2) of the ICCPR and recognizes that the crimes were already defined under international law at the time of their commission.
