Public international law operates within a legal order fundamentally different from municipal legal systems. Unlike domestic law, which derives authority from a sovereign legislature and is enforced through hierarchical courts, international law functions within a decentralised system composed primarily of sovereign states. This structural distinction has historically shaped debates regarding the relationship between international law and municipal law. Two principal theories have been advanced to explain this relationship: monism and dualism. Monist theorists argue that international and municipal law form part of a single legal system.

According to this view, international law may operate directly within domestic legal orders and may even prevail over inconsistent national legislation. Dualist theorists, by contrast, regard the two systems as separate and independent. They maintain that international rules must be transformed into domestic law through legislative action before they can create rights or obligations within the municipal legal order.

Treaties represent one of the principal sources of international legal obligation. They are agreements concluded between states or other international actors that are intended to create binding legal obligations governed by international law. Although treaties bind states at the international level, their domestic effect varies depending on constitutional arrangements. In some jurisdictions treaties become automatically enforceable upon ratification, while in others legislative incorporation is required before courts may apply them. This diversity illustrates the continuing tension between the international legal order and municipal constitutional structures.

The emergence of international organisations has further complicated this relationship. Organisations such as the United Nations possess legal personality distinct from their member states and exercise powers conferred upon them by founding treaties. Their decisions may influence domestic law through mechanisms ranging from binding resolutions to the development of international norms. At the same time, the authority of such organisations ultimately derives from the consent of states, reflecting the continuing centrality of state sovereignty within international law.

Questions of state recognition and state succession also reveal the interaction between political realities and legal principles in international law. Recognition refers to the acknowledgment by existing states that a political entity satisfies the criteria of statehood and may participate in international relations. While the declaratory theory maintains that recognition merely confirms an already existing state of affairs, the constitutive theory suggests that recognition by other states plays a decisive role in conferring international legal personality.

State succession raises further complexities when sovereignty over territory changes through events such as decolonisation, dissolution, or territorial transfer. The successor state may inherit treaty obligations, property rights, or international responsibilities of the predecessor state, though the extent of such continuity depends on the nature of the succession and the applicable rules of international law. These questions demonstrate how international law continually adapts to political transformation while attempting to preserve stability and legal continuity within the international community.
