This study examines the international legal framework governing secret chemical experiments conducted on humans, whether in times of peace or during armed conflicts. It investigates the legality of such practices under the rules of public international law, particularly international humanitarian law, international human rights law, and international criminal law. The focus is placed on documented cases where vulnerable groups—such as prisoners of war and ethnic or religious minorities—were subjected to coercive experiments without their free and informed consent, in violation of fundamental international principles such as human dignity, non-discrimination, and the prohibition of cruel or inhuman treatment.
The study highlights relevant legal provisions, including Article 7 of the International Covenant on Civil and Political Rights (ICCPR), Article 11 of Additional Protocol I to the Geneva Conventions, and Article 8 of the Rome Statute of the International Criminal Court. It also addresses the continuing responsibility of states for these acts, even following a change in political regime, in accordance with the principle of the continuity of international responsibility.
The study concludes that international law unequivocally prohibits the use of humans in secret coercive chemical experiments, recognizing such acts as grave violations that warrant investigation and prosecution—whether committed during armed conflict or peacetime. It underscores the importance of accountability and the imperative to prevent impunity.
