International Criminal Court
A permanent court that prosecutes individuals for crimes such as genocide, crimes against humanity, war crimes, and aggression.

How It Works
The International Criminal Court (ICC) operates as a permanent international tribunal designed to hold individuals accountable for the gravest crimes under international law. It prosecutes cases involving genocide, crimes against humanity, war crimes, and the crime of aggression. Unlike national courts, which handle crimes within their own jurisdictions, the ICC steps in only when national courts are unwilling or unable to prosecute these crimes, following the principle of complementarity.
The ICC's jurisdiction is limited to crimes committed on the territory of states that have ratified the Rome Statute or by their nationals, unless the United Nations Security Council refers a situation to the ICC. Investigations and prosecutions are initiated either by the ICC Prosecutor's own initiative, with approval from the Pre-Trial Chamber, by referrals from states parties, or by the Security Council.
Why It Matters
The ICC plays a crucial role in the global justice system by providing a legal mechanism to address and deter the most serious violations of human rights and international humanitarian law. It helps fill gaps where domestic legal systems fail due to incapacity or unwillingness to prosecute offenders. This promotes accountability, deters future atrocities, and aims to deliver justice to victims.
By holding individuals, including political and military leaders, responsible, the ICC reinforces the principle that no one is above the law. Its existence also strengthens international norms against impunity and contributes to peace and security by addressing the roots of conflict through justice.
International Criminal Court vs Ad Hoc Tribunals
While the ICC is a permanent court, ad hoc tribunals are temporary courts established to address specific conflicts or situations, such as the International Criminal Tribunal for the former Yugoslavia (ICTY) or Rwanda (ICTR). Ad hoc tribunals are created by the United Nations Security Council and have limited temporal and geographic jurisdiction.
The ICC, on the other hand, has a broader mandate and ongoing jurisdiction over crimes committed after its establishment in 2002. It operates based on the Rome Statute, a multilateral treaty, and is independent of the UN, although it cooperates with it.
Real-World Examples
One notable case is the ICC's prosecution of former Congolese militia leader Bosco Ntaganda, who was convicted in 2019 for war crimes and crimes against humanity committed in the Democratic Republic of Congo. This case marked the first ICC conviction based on charges including sexual slavery and the recruitment of child soldiers, illustrating the court's role in addressing complex international crimes.
Common Misconceptions
A frequent misconception is that the ICC has universal jurisdiction over all international crimes worldwide. In reality, its jurisdiction is limited geographically and temporally, and it respects the sovereignty of states by acting primarily when national courts fail.
Another misunderstanding is that the ICC prosecutes states; however, it prosecutes individuals only. States themselves cannot be put on trial before the ICC.
Finally, some believe the ICC can initiate investigations anywhere at any time. Investigations require specific triggers such as referrals by states, the Security Council, or the Prosecutor’s authorization with judicial approval, ensuring checks and balances in its operations.
Example
In 2019, the ICC convicted Bosco Ntaganda for war crimes and crimes against humanity committed in the Democratic Republic of Congo.
