Phase IFoundation

Background

Overview

Understanding the ICC is crucial for analyzing international justice, human rights, and the evolving landscape of international law. It highlights the challenges of enforcing international norms against sovereign states and powerful individuals, and India's nuanced position on international tribunals.

International Humanitarian Law (IHL) is a set of rules seeking to limit the effects of armed conflict, protecting persons who are not or are no longer participating in hostilities and restricting the means and methods of warfare. Key instruments include the Genocide Convention of 1948, and its enforcement relies on international justice mechanisms like the International Court of Justice (ICJ) and the International Criminal Court (ICC).
