dual criminality

**Dual Criminality** refers to a legal principle in international law where an act must be considered a crime in both the requesting and the requested country for extradition or mutual legal assistance to proceed. This concept ensures that individuals are only prosecuted or extradited if the conduct in question violates the laws of both jurisdictions involved. Dual criminality helps maintain fairness and respect for differing legal systems while facilitating cooperation in combating cross-border crime.
