International Law Applications In Domestic Criminal Cases
1. Introduction: International Law and Domestic Criminal Law
International law—including treaties, conventions, and customary law—increasingly influences domestic criminal law. The interaction occurs in cases such as:
Human trafficking
War crimes and genocide
Cybercrime with transnational elements
Terrorism and money laundering
Environmental and maritime offenses
Domestic courts often incorporate international conventions into national statutes or interpret existing law in light of international obligations.
Key Mechanisms in India
Treaty Incorporation:
India follows a dualist approach, meaning treaties are not automatically part of domestic law until enacted by Parliament.
Directive Interpretation:
Courts interpret domestic laws in harmony with international obligations.
Customary International Law:
Recognized and applied by courts even without legislative enactment, especially in human rights and war crime cases.
2. Key Principles in Application
Supremacy of Domestic Legislation: International law guides, but cannot override statutes.
Harmonious Interpretation: Courts often interpret statutes in light of international conventions.
Direct Enforcement: Some international obligations, like human trafficking conventions, are enforced via domestic statutes.
Judicial Activism: Courts actively use international law to strengthen human rights and procedural safeguards.
