Key differences between municipal and international law
-
Scope and jurisdiction: Municipal law applies within a specific country, while international law applies to relations between states and international entities.
-
Sources of law: Municipal law is derived from a country's constitution, , , and case law. International law is based on treaty, international agreements, and customary international law.
-
Enforcement: Municipal law is enforced by domestic legal and administrative institutions. International law relies on international bodies, diplomatic efforts, and mutual consent for enforcement.
-
Focus: Municipal law addresses internal matters of a state, including criminal justice, civil disputes, and regulatory issues. International law deals with issues such as diplomatic relations, trade agreements, and global security.
Article 27 of the Vienna Convention on the Law of Treaties from 1969 provides that if a treaty conflicts with a state's municipal law (including the state's constitution), the state is still obliged to meet its obligations under the treaty. The only exception is provided by Article 46 of the Vienna Convention if a state's expression of consent to be bound by a treaty was a manifest violation of a "rule of its internal law of fundamental importance".[.
