The world has witnessed countless bloody wars and cruel atrocities against innocent populations. However, international law has always lagged behind in banning both cruel methods and means of war and weapons as well as in holding those responsible who violate these rules. To quote the well-known maxim of Cicero: “inter arma enim silent lēgēs”. This has resulted in the much-criticized phenomenon of the “culture of impunity” in which there was no accountability for the most heinous crimes. The adoption of the Nuremberg Charter in the aftermath of the Second World War gave birth to the category of “Supreme Crimes”. What are these crimes and the unique stories behind them? Who did insist on including the “crime against peace” in the Nuremberg Charter and why did the city of Lviv become important in drafting those crimes? How to have the institutional framework and mechanisms of accountability of international criminal law developed? What are their achievements and shortcomings? What challenges do the prosecution and defense face in international criminal law? These and similar questions are to be addressed by Beti Hohler, a trial lawyer for the ICC's Office of the Prosecutor and by Michael Herz, a legal officer in the Office of Public Counsel for the Defence at the ICC in a conversation with Lénárd Sándor, head of the Center of International Law at the Mathias Corvinus Collegium.
