alþjóðalaga

Alþjóðalög, also known as public international law, refers to the system of laws, rules, and principles that govern the relations between states and other international actors, such as international organizations. It is distinct from domestic law, which applies within a single country. The primary sources of alþjóðalög include treaties, customary international law, and general principles of law.

Treaties are formal agreements between states, negotiated and ratified according to their own internal procedures. Customary international law arises from the consistent practice of states, undertaken with the belief that such practice is legally required. General principles of law are fundamental legal concepts recognized by most national legal systems.

Alþjóðalög addresses a wide range of issues, including the conduct of war, human rights, international trade, environmental protection, and the use of outer space. Key institutions involved in the development and enforcement of alþjóðalög include the United Nations, the International Court of Justice, and various international tribunals. While alþjóðalög is not enforced by a global police force in the same way as domestic law, states generally adhere to it due to considerations of reciprocity, national interest, and the desire for international order. Violations can lead to diplomatic protests, sanctions, or legal proceedings before international courts.
