On 6 October 2025, an educational webinar on “Ways to Implement the Provisions of the Rome Statute of the ICC into National Legislation ” was held, organized by the Research Service of the Verkhovna Rada of Ukraine in cooperation with the Institute of the Danube Region and Central Europe (Vienna, Austria).

The event was organized as part of a series of educational webinars focusing on the EU integration dimension of Ukraine’s legal reforms and the alignment of national legislation with international legal standards

The keynote speaker was Dr. Gabriel M. Lentner, Associate Professor of International Law and Arbitration at the University of Continuing Education Krems (Austria), Lecturer at the University of Vienna and the University of Göttingen (Germany), and Fellow of the Transatlantic Technology Law Forum at Stanford Law School.

During the lecture, the following key issues were discussed:

• the legal obligations of States Parties regarding the implementation of the Rome Statute, including the criminalization of international crimes, the surrender of individuals to the International Criminal Court (ICC), and the facilitation of international cooperation;

• models for incorporating international treaties into national legislation – direct (monist), legislative (dualist), and hybrid approaches;

• the core principles of criminalization of genocide, crimes against humanity, war crimes, and the crime of aggression;

• practical examples of how the Statute’s provisions have been implemented in the legal systems of Canada, Germany, the United Kingdom, Portugal, and other countries;

• the main challenges arising from the interaction between international and national law, including issues of immunity, sovereignty, and the need to strengthen institutional capacity.

Special emphasis was placed on the principle of complementarity, according to which national courts bear the primary responsibility for prosecuting international crimes, while the ICC intervenes only when a state is unable or unwilling to deliver justice.

Simultaneous interpretation for the webinar was provided thanks to “Ukraine2EU – EU Integration Support Programme for Ukraine”, which made the event accessible to a broader audience.
