One year and half after Russia’s full-scale invasion of Ukraine, the brazen breach of the UN Charter continues to pose a great threat to the rules-based international order, raising important questions on how the global rule of law can be defended and restored. From the pursuit of criminal justice for Russia’s aggression and atrocities, domestic prosecutions to the International Criminal Court and a prospective aggression tribunal, to the importance of upholding State responsibility and accessing remedy, reparations, and reconstruction through appropriate legal mechanisms.

What should be the vision for the future role of the UN in upholding, maintaining, and restoring international peace? And what is the role of organisations such as the IBA in shaping the up the global rule of law?
