Study Notes

Introduction to International Law

International law encompasses a diverse body of rules and principles that govern the conduct of states and other international actors.
It aims to maintain peace, promote cooperation, and resolve disputes.
The sources of international law include treaties, customary international law, general principles of law, and judicial decisions.
It's distinct from national law, applying to relations between states rather than within a single state.

Nature and Sources of International Law

International law is largely based on state consent. States are primary subjects but other entities like international organizations and individuals are becoming increasingly relevant.
Treaties are written agreements between states; their effectiveness is dependent upon state consent and ratification.
Customary international law arises from consistent and widespread state practice accompanied by a belief that the practice is legally obligatory (opinio juris).
General principles of law recognized by civilized nations can also be sources of international law.

Key Principles of International Law

Sovereignty: States are independent and equal, not subject to external interference in their internal affairs.
Good faith: States must act in good faith when conducting their international relations.
Pacta sunt servanda: Agreements are binding (treaties).
Self-determination: Peoples have the right to freely determine their political status and pursue their economic, social, and cultural development.
Responsibility for harm: A state is responsible when it violates a rule of international law and causes harm.

International Law and International Relations

International law plays a complex role in shaping international relations, acting as a framework for cooperation and conflict resolution, influencing the behaviour of states and other entities.
States often use international law to advance their interests and goals, which can lead to conflict and negotiation.
International law can foster cooperation by establishing rules and mechanisms for dispute settlement that avoid outright conflict.

Branches of International Law

International human rights law protects fundamental rights and freedoms of individuals.
International humanitarian law regulates the conduct of armed conflict to limit suffering.
International criminal law addresses grave crimes against international peace and security, such as genocide and war crimes.
International economic law encompasses rules governing trade, investment, and financial relations between states.
Environmental law seeks to regulate and protect the environment.

Subjects of International Law

States are the primary subjects and actors in international law, possessing rights and obligations under international rules.
International legal organizations, like the United Nations, hold defined powers and can undertake international actions.
Individuals are increasingly recognized as having international legal personality, though their rights and duties are still evolving.
Non-state actors, like multinational corporations and NGOs, are gradually becoming more involved in the international legal system, even though their capacity varies.

Dispute Settlement Mechanisms

International law provides mechanisms for resolving disputes between states, including negotiation, mediation, arbitration, and judicial settlement (e.g. International Court of Justice).
These approaches aim to prevent and settle conflicts peacefully.

Enforcement of International Law

Enforcement of international law is a complex issue due to the lack of a global police force.
Diplomatic pressure, sanctions, and UN action can be employed to respond to violations.
State reputation and international norms play a critical role in upholding international law.

Relationship with National Laws

International law and domestic laws interact. States domesticate international law through implementation processes and interpretations.
Constitutional rules and domestic court decisions often influence how national courts apply and interpret international law.
