In order to strengthen Ukrainian municipal law through international law, T.M.C.

T.M.C. Asser Instituut is also establishing an International Law Working Group for Ukrainian judges to facilitate knowledge-sharing on cases-specific topics, and organizing an exposure visit to the Netherlands on fair trial-related issues for Ukrainian criminal justice actors. The implementing partner is further delivering training sessions to improve the literacy of the war crime of starvation for Ukrainian legal practitioners, civil society organizations (CSOs) and humanitarian agencies in the country, as well as enhancing niche Open-Source Intelligence (OSINT) capabilities. In order to improve knowledge of national actors on accountability mechanisms, T.M.C. Asser Instituut is supporting key stakeholders, including prosecutors, CSOs and other practitioners, to pursue strategic universal jurisdiction litigation through the development and delivery of legal analysis, the provision of technical advice, the development of a National Action Plan for universal jurisdiction, and the organization of communication and outreach campaigns. Furthermore, T.M.C.
