Phase IFoundation

Background

Overview

UPSC often asks about international organizations, their mandates, membership, and controversies surrounding them, especially concerning international justice and human rights. The ICC's role in holding individuals accountable for grave international crimes and the challenges it faces due to non-membership of key states are crucial for understanding global governance and international law.

The International Criminal Court (ICC) is an intergovernmental organization and international tribunal located in The Hague, Netherlands. It is the first and only permanent international court with jurisdiction to prosecute individuals for the most serious international crimes: genocide, crimes against humanity, war crimes, and the crime of aggression.
