The International Court of Justice (ICJ) serves as the principal judicial organ of the United Nations, tasked with resolving disputes between states through the application of international law. In a world where the use of force remains one of the most contested aspects of global politics, the Court plays a vital role in defining the legal boundaries of state conduct and upholding the principles of sovereignty and legality. This committee examines the legality of the 2003 invasion of Iraq, a moment that sparked widespread international debate. The respondent states, the United States and the United Kingdom, justified their actions on grounds including self-defense and the enforcement of prior United Nations Security Council resolutions. The Republic of Iraq, however, challenges this justification, arguing that the use of force was a violation of its sovereignty and a breach of international law. Delegates will engage with key legal principles such as the prohibition of the use of force under the UN Charter and the conditions under which self-defense may be invoked. The ICJ will deliberate on whether the actions taken in 2003 were legally justified or whether they set a dangerous precedent for dictated intervention. Through careful legal reasoning and argumentation, the Court seeks to address a basic question: when, if ever, is the use of force truly lawful?
