Universal Jurisdiction and International Criminal Law

Universal jurisdiction (UJ) is a principle that allows a state to prosecute individuals for serious international crimes regardless of where the crime was committed or the nationality of the perpetrator or victim.

International Criminal Law (ICL) governs crimes recognized as serious violations of human rights and humanitarian law, including:

Genocide – Intent to destroy a national, ethnic, racial, or religious group

War crimes – Violations of laws of armed conflict

Crimes against humanity – Systematic or widespread attacks on civilians

Torture and piracy – Recognized as universally prosecutable

Effectiveness depends on:

Legal recognition by domestic courts

Cooperation with international tribunals

Political will and enforcement capacity

Legal Framework

International

Geneva Conventions (1949) – War crimes and protection of civilians

Rome Statute of ICC (1998) – Establishes International Criminal Court

Convention on the Prevention and Punishment of the Crime of Genocide (1948) – Genocide as universal crime

UN Security Council Resolutions – Can create ad hoc tribunals (e.g., ICTY, ICTR)

Domestic

Many countries adopt UJ in national statutes to prosecute crimes regardless of location, e.g., Belgium, Germany, Spain, UK, India (partially through incorporation of Geneva Conventions and UAPA for terrorism-related crimes).
