    Study Notes

    Introduction to Customary International Law

    • Customary International Law (CIL) is derived from the consistent practices of States, accepted as legally binding.
    • It requires more than just ordinary habits, reflecting a long-standing, widespread practice with a sense of legal obligation.
    • CIL is not subject to sanctions for individual breaches, focusing on consistent practices and obligations.
    • CIL emerges from the need for legal obligations based on legitimate expectations created by the conduct of States.
    • CIL is defined in Article 38(1) of the Statute of the International Court of Justice (ICJ) as "international custom, as evidence of general practice accepted as law."
    • CIL is based on two elements: "State Practice" and "Opinio Juris."

    State Practice and Opinio Juris

    • State Practice refers to the actual behavior of States and international organizations.
    • Opinio Juris signifies a belief that such behavior is legally binding.
    • These two criteria are essential for establishing customary rules in international law.

    Key Cases Illustrating CIL

    • Colombia v. Peru (1950) - The Asylum Case

      • This case involved the granting of political asylum to a coup leader, Mr. Haya de la Torre, in the Colombian embassy in Peru. The Colombian government alleged that a regional custom in Latin America entitled it to qualify the offense for the purpose of asylum.
      • The ICJ ruled that the Colombian government needed to prove the existence of a constant and uniform usage practiced by relevant States to establish a binding custom.

    • The Scotia (1872) - US Supreme Court

      • This case involved a collision between an American sailing vessel and a British steamer.
      • The American vessel violated US and international maritime regulations regarding colored lights for navigation.
      • The court held that the widely accepted navigational rules, adopted by many maritime states, had become part of the law of the sea.

    Customary Rules in International Law

    • Customary rules are often unwritten and uncodified.
    • The International Law Commission (ILC) plays a role in codification (Lex Lata) and progressive development (De lege ferenda) of international law.
    • State-practice requires analyzing how States behave regarding a specific issue, including their actions and statements.

    Factors Influencing State Practice

    • Influence of specific States: The UK significantly impacted the development of the law of the sea, while the Soviet Union and the US influenced space law.
    • State behavior: "State practice" includes various legal acts and practices.

    Protest, Acquiescence, and Change

    • Acquiescence: A State's silent acceptance of a developing custom can be seen as consent.
    • Protest: Persistent objection to a new custom from its inception can exempt a State from its binding nature.
    • Persistent Objector: A State that consistently objects to a new custom from its beginning is not bound by that rule.

    Other Aspects of Customary Rules

    • Local Custom: Specific customs can apply to particular regions, requiring participation of all States in that region. Silence does not automatically imply acceptance.
    • Omission as State Practice: States' omissions, refraining from actions due to a sense of legal obligation, can contribute to establishing custom.
    • Regional Custom: Customary rules can apply to specific regions of the world. A minimum of two States can create a regional custom, which only applies to the region.
    • General Principles of Municipal Law: General principles of law, derived from municipal legal systems, may apply to disputes between States.

    Other Sources of Public International Law (PIL)

    • Jus Cogens: Fundamental principles of international law from which no derogation is permitted. Examples: prohibition of genocide, slavery.
    • Erga Omnes Obligations: Obligations owed to the international community as a whole.
    • Resolutions of International Organizations: Resolutions can contribute to the development of Customary International Law, especially those adopted by a majority of states and with consistent content. Additionally, resolutions can be used to interpret existing international law.
    • Soft Law: Non-binding agreements and principles that are considered important for international cooperation and development. They do not have the force of law, but can influence state behavior.

    Example of Jus Cogens

    • Article 53 of the Vienna Convention on the Law of Treaties states that a treaty is void if it conflicts with a jus cogens norm.

    Example of Erga Omnes Obligation

    • The Barcelona Traction Case determined that certain obligations are owed to the international community as a whole. The violation of these obligations affects not only the state that is directly injured, but also all States.

    Examples of Resolutions of International Organizations

    • UN General Assembly Resolutions can be considered evidence of custom if they are adopted by a majority of States, including those whose interests are affected, repeatedly, and with the same content.
    • UN Security Council Resolutions are binding if adopted under Chapter VII of the UN Charter (regarding breaches of international peace and security).
