This Article examines the involvement of the International Criminal Court (“ICC”) in Georgia and Ukraine, and the impact the ICC has had on mobilizing national authorities and civil society in the two countries, in order to address impunity for international crimes. Both Georgia and Ukraine, with Russia as their adversary, share many commonalities in dealing with the conflict-related crimes. However, it appears that the ICC’s involvement has produced different effects in each country in terms of the ability of domestic authorities to deal with the conflict-related crimes. This Article describes how the ICC’s involvement in Georgia and Ukraine has affected domestic processes in terms of legal reform, mobilization of civil society, and domestic prosecution of the conflict-related crimes. It compares and contrasts both situations by highlighting the challenges encountered by both countries, and the ways in which the ICC has impacted domestic processes.
