The Challenges of Prosecuting Atrocity Crimes in International Tribunals
Quick fact
The International Criminal Court has convicted only a few individuals in its first 20 years, despite investigating some of the world's worst atrocities—a success rate far lower than typical domestic courts, due to massive evidentiary and cooperation obstacles.
Why this is interesting
You might think that after millions of deaths, international courts would have an easy time convicting the masterminds. Yet since Nuremberg, only a handful of senior leaders have ever faced justice. Why is it so hard?

Understanding The Challenges of Prosecuting Atrocity Crimes in International Tribunals
Imagine trying to build a case against a powerful warlord while bombs are still falling. Unlike a domestic murder trial where police secure the crime scene, international prosecutors must gather evidence from war zones, often years after the fact. Witnesses may be scattered as refugees, too terrified to testify, or may have been killed. States that could provide arrest warrants or satellite images may refuse for political reasons. The tribunal itself has no police force; it must rely on states to execute its orders. So every step—from collecting forensic evidence to bringing suspects to the courtroom—is a battle against violence, politics, and time.
A deeper explanation
The core challenge is that international tribunals are designed to uphold law while being utterly dependent on the very states that might be implicated. Under the Rome Statute, the ICC operates on the principle of complementarity, meaning it only steps in when states are unwilling or unable to genuinely prosecute. But 'unwillingness' is hard to prove, and states can claim they are investigating to shield suspects. Even when trials proceed, securing evidence from hostile governments, protecting witnesses from reprisals, and reconciling different legal traditions (like civil law vs. common law) create procedural friction. Moreover, the suspects are often still in power, controlling the territories where evidence lies. This structural weakness—sovereignty versus justice—explains why international prosecutions are rare and often select only a few symbolic leaders, leaving many perpetrators untouched. The mechanism is not a failure of law itself, but the absence of an enforcement authority that can compel obedience.
