When a panel of U.N. judges hands down a verdict next week in the trial of former Bosnian Serb military chief Gen. Ratko Mladic, it will mark the end of a ground-breaking era in international law. Yet a new age of international justice is already underway, with other temporary courts and tribunals springing up around the world to prosecute atrocities.

Mladic's trial is the last at the International Criminal Tribunal for the former Yugoslavia, which was set up in 1993 to prosecute crimes committed in the Balkan wars of the early 1990s.

Over 24 years, it has sent dozens of war criminals to jail — from lowly soldiers and prison camp guards to former Bosnian Serb leader Radovan Karadzic — and it developed key jurisprudence in prosecuting atrocities.

Mladic, who insists he is innocent, faces a maximum life sentence if convicted Wednesday of crimes including genocide.

What the Yugoslav court hasn't done, however, is stop such crimes from happening. Allegations of mass murders and persecutions from the past and present are mounting around the world — from Sri Lanka's bloody civil war to the carnage in Syria to abuses seen against Rohingya Muslims who fled by the hundreds of thousands as their towns and villages were torched in Myanmar.

This means the list of locations for future temporary courts is growing ever longer. Just this week, a report by the U.S. Holocaust Memorial Museum and the advocacy group Fortify Rights found there is "mounting evidence" of genocide against the Rohingya. U.S. Secretary of State Rex Tillerson said the U.S. was deeply concerned by "credible reports" of atrocities committed by Myanmar's security forces and called for an independent investigation.
