Model UN Background Guide

Committee: International Court of Justice (ICJ)

Topic: Ukraine v. Russian Federation

Conference Year: 2025

1. Topic Background

The case of Ukraine v. Russian Federation at the International Court of Justice (ICJ) arises from the ongoing conflict and territorial disputes following Russia’s annexation of Crimea in 2014 and the subsequent war in Eastern Ukraine. The conflict escalated dramatically with Russia’s full-scale invasion of Ukraine in February 2022, which triggered widespread international condemnation and numerous legal challenges. Ukraine has brought several cases against Russia before the ICJ, alleging violations of international law including breaches of treaties, acts of aggression, and violations of sovereignty and territorial integrity.

Historically, the roots of the dispute trace back to the dissolution of the Soviet Union in 1991, when Ukraine declared independence, inheriting Crimea and other territories. Russia’s annexation of Crimea in 2014 was widely regarded as a violation of international law, particularly the 1994 Budapest Memorandum and the UN Charter. The ICJ case specifically addresses Russia’s alleged breaches of the 1948 Convention on the Prevention and Punishment of the Crime of Genocide (Genocide Convention) and other international obligations.

This issue remains on the ICJ agenda in 2025 due to ongoing hostilities, unresolved legal questions about state responsibility, and the broader implications for international law concerning sovereignty, territorial integrity, and the use of force. The ICJ’s rulings in this case could set important precedents for the adjudication of interstate conflicts and enforcement of international legal norms.

2. Key Actors

• Ukraine: The applicant state seeking legal redress for alleged violations by Russia, including unlawful use of force, breach of treaties, and acts constituting genocide or ethnic cleansing. Ukraine’s government emphasizes restoration of sovereignty and territorial integrity.

• Russian Federation: The respondent state, denying allegations of illegal annexation and genocide, asserting historical claims to Crimea and justifying its military actions as protective measures for Russian-speaking populations and national security.

• International Court of Justice (ICJ): The principal judicial organ of the United Nations responsible for adjudicating disputes between states in accordance with international law. The ICJ’s role is to interpret relevant treaties and conventions and issue binding judgments.

• United Nations: Particularly the General Assembly and Security Council, which have passed resolutions condemning the invasion and annexation, though the Security Council is often deadlocked due to Russia’s veto power.

• Organization for Security and Cooperation in Europe (OSCE): Active in monitoring ceasefires and human rights in Eastern Ukraine, though with limited enforcement capabilities.

• European Union (EU) and North Atlantic Treaty Organization (NATO): Political and security actors supporting Ukraine through sanctions on Russia, diplomatic pressure, and military aid, though not direct parties to the ICJ case.

3. Bloc Positions

Western Bloc (EU, United States, Canada, UK, Australia, Japan)

• Strongly support Ukraine’s claims and the ICJ’s jurisdiction.
• Emphasize respect for sovereignty, territorial integrity, and international law.

Non-Aligned and Developing States (India, China, South Africa, Brazil, many African and Latin American countries)
