Mechanisms to ensure criminal liability for the crime of aggression of the Russian Federation on the territory of Ukraine

The authors put attention to the key features of the mechanism of ensuring criminal liability for the crime of aggression committed by the russian federation on the territory of Ukraine, because despite the rather extensive system of legal acts regulating this issue, there are many obstacles to bringing perpetrators to international criminal liability. This study focuses on the judicial practice that demonstrates the absence of a proper effective mechanism at the legislative level to regulate the issue of bringing the russian federation to legal responsibility at the international legal level for acts of aggression and other international crimes, taking into account the compensation for the damage caused by them. In particular, among the important achievements of the study is the creation of a Special Tribunal with the possible conclusion of a separate International Code of War Crimes, which will detail the disposition of articles in view of modern realities, as well as the grounds and principles of international criminal liability, possible sanctions and grounds for exemption from liability and punishment. At the same time, the author studied the national legal framework in terms of amendments and additions to the Criminal Procedure Code of Ukraine of 2022 to Section IX-2, which pose new challenges to the doctrine of criminal procedure law related to theoretical and applied rethinking of ideology, allowing for a fresh look at the issues of procedural science which have already been studied
