1. The procedure for extradition of the accused and convicted persons.
Article 521
(1) If extradition of the same person is requested by several foreign countries for the same crime, the primacy will be given to the application of the country whose citizen the person is, and if that country does not request the extradition- to the application of the country on which territory the crime has been committed, and if the crime has been committed on the territory of several countries or if it is not known where it is committed- to the application of the country which has first requested for extradition .
(2) If extradition of the same person is requested by several countries for different crimes, the primacy will be given to the application of that country whose citizen the person is, and if that country does not request extradition- to the application of the country on whose region is committed the most severe crime, and if the crimes are equally severe- to the application of the country which has first requested for extradition .
3. Where a determination under paragraph 2 (a) has not been made, the requested State may, at its discretion, pending the determination of the Court under paragraph 2 (b), proceed to deal with the request for extradition from the requesting State but shall not extradite the person until the Court has determined that the case is inadmissible. The Court's determination shall be made on an expedited basis.
4. If the requesting State is a State not Party to this Statute the requested State, if it is not under an international obligation to extradite the person to the requesting State, shall give priority to the request for surrender from the Court, if the Court has determined that the case is admissible.
