The Courtroom at the Center of Everything
How domestic courts became the last line of international justice
How domestic courts became the last line of international justice
The plane touched down in Tripoli just hours after the man inside should have been transferred to The Hague. On January 21, 2025, Osama Almasri Najim, a former head of Libyan judicial police suspected of murder, torture, and sexual violence at the notorious Mitiga prison, walked off an Italian government aircraft as a free man. He was supposed to be in the custody of the International Criminal Court (ICC). Instead, Italy released him two days after his arrest in a Turin hotel, and the warrant sitting in ICC files went unfulfilled.
Cristina Orsini of Lawyers for Justice in Libya called it a blow to the Rome Statute, the treaty that governs the ICC. But it was also something else: another data point in a longer, quieter story about where international justice actually happens.
Where International Crimes are Prosecuted
Share of prosecutions by court type
Nearly two-thirds of all international crime prosecutions — 64% — now happen in domestic courts. Hybrid tribunals handle about 20%. The UN ad-hoc bodies that defined international justice after Rwanda and Yugoslavia? They account for just 15%.
The era of the purpose-built international tribunal, created in the image of Nuremberg, is no longer dominant. The courtroom that matters most is staffed by national judges, working under national law, answerable to national political systems.
This shift was decades in the making. Through the 1990s, the vocabulary of prosecution itself expanded. Terrorism charges appeared alongside war crimes. Material support statutes emerged. Countries like the Netherlands, Tanzania, and Bosnia each developed their own approaches, different clusters of charges, different timelines.
The Global Landscape of Genocide Prosecutions
Prosecution of genocide charges in domestic courts, by country
Rwanda and Tanzania show the highest concentrations of genocide-specific charges. Bosnia carries the weight of Srebrenica. But looking at the Netherlands, the United States, France, Argentina, Canada, the international crimes they prosecute are much more varied. Genocide sits alongside war crimes, crimes against humanity, terrorism. These countries have stretched their legal frameworks to prosecute crimes committed on the other side of the world, by people who passed through their borders or whose victims did.
The geography of accountability no longer follows the geography of atrocity.
The country that prosecutes more international crimes than any other, the United States, never ratified the Rome Statute. It actually "unsigned" the treaty in 2002.
Together, non-Rome Statute countries account for 139 of 355 domestic prosecutions — nearly 40%.
The architecture of international justice depends on treaties that some of its most active participants refuse to join.
Prosecutions by Rome Statute Status
Domestic cases in treaty members vs. non-members
International justice migrated into domestic courts not by accident but by design. UN tribunals are expensive, slow, and depend on Security Council consensus that rarely materializes. Domestic courts offered a workaround. The Genocide Prosecution Network coordinates cross-border efforts. National units combine counterterrorism and international crimes expertise. On paper, this is the mature, innovative face of accountability, courts doing more, charging more, potentially delivering fuller justice than the more traditional institutions ever could.
But domestic courts are political institutions. They sit inside states that have bilateral relationships, energy dependencies, trade routes, migration deals with countries whose nationals show up on ICC warrant lists. When those pressures collide with international obligations, that 64% figure stops looking like capacity and starts looking like vulnerability.
The case for this system rests on one assumption: that domestic courts can be trusted to carry the weight placed on them. Italy's failure with Almasri doesn't disprove that assumption, no single case can, but it's a stress test the system can't afford to ignore.
What happens when the court at the center of everything is answerable to a government that finds it inconvenient?
