After spending more than a decade and nearly $300 million, the United Nations-backed tribunal prosecuting the crimes of the Khmer Rouge has convicted just three men.

The tribunal’s awkward hybrid of Cambodian and international legal systems pairs Cambodian and foreign judges, who must reach at least a limited agreement on decisions. That formula preserved the Cambodian sense of sovereignty while attempting to hold the court to legal standards advocated by the United Nations. Over the years, it has led to clashes between the international and Cambodian staff members over the scope of the trial.
