Netherlands

A strong proponent of international law and maritime governance.

Role in topic

As the host country for the competition in Utrecht, NLD, the Netherlands plays a significant role in promoting the study and application of the Law of the Sea. Its historical reliance on maritime trade and its commitment to international legal frameworks underscore its interest in robust maritime governance.

United States

Active in maritime affairs but has not ratified UNCLOS.

Role in topic

The United States, despite not being a party to UNCLOS, adheres to most of its provisions as customary international law. Its extensive naval presence and economic interests in global shipping lanes mean it is deeply invested in the principles of freedom of navigation and the peaceful resolution of maritime disputes.

China

A major maritime power with significant interests in territorial claims and resource exploitation.

Role in topic

China's growing economic and military power places it at the center of many discussions concerning the Law of the Sea, particularly regarding its claims in the South China Sea. Its perspective often emphasizes national sovereignty and historical rights, leading to complex interactions with other claimant states.

Philippines

A claimant state in maritime disputes, often seeking international legal recourse.

Role in topic

The Philippines is a key player in maritime disputes, particularly in the South China Sea. It has actively pursued international legal avenues, such as arbitration, to resolve territorial and maritime boundary issues, highlighting the importance of international law for smaller states facing larger powers.

Norway

A leading nation in ocean management and Arctic maritime issues.

Role in topic

Norway, with its extensive coastline and interests in the Arctic, is a significant voice in discussions on sustainable ocean management, fisheries, and continental shelf delimitation. Its approach often balances economic interests with environmental protection and adherence to international law.

Topics & background

The history behind each committee topic and the states that shape it.

Law of the Sea

The modern law of the sea is built on centuries of state practice balancing the freedom of the seas, championed by Hugo Grotius in 1609, against coastal state claims to adjacent waters. After fragmented codification attempts in the 1930 Hague Conference and the four 1958 Geneva Conventions, states negotiated the 1982 United Nations Convention on the Law of the Sea (UNCLOS), which entered into force in 1994 and now has over 165 parties. UNCLOS established the territorial sea, contiguous zone, exclusive economic zone, continental shelf, high seas, and the Area beyond national jurisdiction, and created three institutions: the International Tribunal for the Law of the Sea (ITLOS), the International Seabed Authority (ISA), and the Commission on the Limits of the Continental Shelf (CLCS). The regime is under sustained pressure from contemporary disputes and new uses of the ocean. Overlapping maritime claims in the South China Sea, the Arctic, and the Eastern Mediterranean have produced landmark arbitrations, including the 2016 South China Sea Award under Annex VII. ITLOS has issued advisory opinions on flag state responsibility (2015) and, in 2024, on states' obligations to protect the marine environment from greenhouse gas emissions. The 2023 Agreement on Biodiversity Beyond National Jurisdiction (BBNJ) extends UNCLOS to high-seas biodiversity, while the ISA continues negotiating a Mining Code for deep-seabed exploitation amid sharp disagreement over a precautionary moratorium. Key legal questions today include how UNCLOS interacts with climate change obligations, the legality of artificial islands and militarization of disputed features, the rights of geographically disadvantaged and archipelagic states, and the binding force of compulsory dispute settlement under Part XV when major powers contest jurisdiction. These tensions form the backdrop against which moot problems on maritime delimitation, environmental protection, and navigational rights are typically framed.

Key players

International Dispute Settlement

International dispute settlement is the architecture by which states, and increasingly other actors, resolve disagreements without resort to force. Article 2(3) of the UN Charter obliges peaceful settlement, and Article 33 lists negotiation, inquiry, mediation, conciliation, arbitration, judicial settlement, and recourse to regional agencies. The Permanent Court of Arbitration (1899) and the Permanent Court of International Justice (1922) institutionalized adjudication, and the International Court of Justice (ICJ), established in 1945 as the principal judicial organ of the UN, has since rendered decisions on territorial sovereignty, state responsibility, treaty interpretation, and the use of force. Specialized fora have proliferated: ITLOS for the law of the sea, WTO panels and the Appellate Body for trade, ICSID and UNCITRAL tribunals for investment, and ad hoc and hybrid criminal tribunals for individual accountability. The field today faces both expansion and contestation. The ICJ's docket has grown rapidly with high-profile cases on genocide (The Gambia v. Myanmar; South Africa v. Israel), occupation and self-determination (Chagos and the 2024 Palestine advisory opinion), and climate change (the 2025 advisory opinion on states' climate obligations). Inter-state arbitration under UNCLOS Annex VII and the PCA remains active, while investor-state dispute settlement is under reform pressure through UNCITRAL Working Group III. At the same time, the WTO Appellate Body has been paralyzed since 2019 due to the United States blocking appointments, and several states have withdrawn or threatened to withdraw from the ICC and ICSID. Core debates concern the consent-based nature of jurisdiction, the proliferation and possible fragmentation of international courts, compliance and enforcement of judgments, the role of provisional measures, and the legitimacy of advisory opinions as quasi-binding pronouncements. Moot problems in this area typically require delegates to navigate jurisdictional objections, admissibility, the law of treaties, and the interaction between primary obligations and procedural mechanisms.
