Problems of Criminal Law and Criminal Procedure in International Search

: During the operational search activities and criminal proceedings it is often necessary to issue an international search warrant for a person in order to arrest and extradite him/her. In such cases, a number of questions related to the regulation of criminal law and criminal procedure arise, the answers to which are not obvious, and are not available in the scientific literature. Based on the analysis of Russian legislation and practice of its application, the standards of international law, as well as scientific information sources and references, the answers to a number of questions have been substantiated, including: the types of offences for which an international search warrant can be issued against a person; whose competence it is to issue an international search warrant against a person; documented justification for issuing an international search warrant against a person; against which persons (with what standing) an international search warrant can be issued; who and at what stage applies the measure of restrain in the form of taking into custody for an internationally wanted person. The answers received provide grounds for improving the regulations governing the declaration of an international search for a person in the Russian Federation with a view to arrest and extradition, as well as the practice of their application.
