International Law vs Domestic Law

International law and domestic law are two distinct legal frameworks that govern different aspects of human interaction. The differences in scope, subjects, sources, enforcement mechanisms, and relationship to sovereignty highlight the distinctive nature and application of international law and domestic law.

Scope: International law operates on a global scale, addressing issues that affect the international community as a whole, such as international peace and security, human rights, and global trade. Domestic law, on the other hand, applies within the borders of a specific country and regulates the conduct of individuals, organisations, and entities within that jurisdiction.

Subjects: International law primarily focuses on the rights, obligations, and responsibilities of states and international actors, including international organisations and individuals. Domestic law, in contrast, governs the conduct and interactions of individuals, organisations, and entities within a specific country.

Sources of law: International law derives its authority from various sources, including treaties, customary practices, general principles of law, and judicial decisions. Domestic law, however, relies on the constitution, statutes, regulations, and case law specific to the country.

Enforcement mechanisms: International law lacks a centralised enforcement mechanism. Compliance with international obligations primarily relies on the consent and voluntary participation of states, diplomatic negotiations, economic sanctions, and the jurisdiction of international courts and tribunals. Domestic law, on the other hand, is enforced through the judicial system and law enforcement agencies within the jurisdiction of a country.

Relationship to sovereignty: International law respects the sovereignty of states and operates based on the consent of participating states. It allows states to maintain their independence while engaging in international cooperation. Domestic law, in contrast, exercises authority over individuals and entities within a specific jurisdiction, regardless of their consent.

Hierarchy of laws: Domestic legal systems often have a hierarchical structure, where constitutional provisions hold the highest authority, followed by statutes, regulations, and case law. International law, however, lacks a rigid hierarchy, and conflicts between different sources of international law are resolved through principles such as lex posterior (later treaty prevails) or lex specialis (specialised treaty prevails).

In summary, international law governs the relations between states and international actors on a global scale, addressing issues of international concern, while domestic law regulates the conduct within a specific country.
