Act of 18 December 1998 on the Institute of National Remembrance – Commission for the Prosecution of Crimes against the Polish Nation as a Ground for Prosecution of Crimes against Humanity, War Crimes and Crimes against Peace

This article discusses definitions of crimes included into the Act of 18 December 1998 on the Institute of National Remembrance – Commission for the Prosecution of Crimes against the Polish Nation, and their usefulness in prosecuting individuals who committed international crimes. It is argued that the provisions of the Act cannot constitute a ground for criminal responsibility of individuals, as they violate the principle of nullum crimen sine lege certa.
