When a Court in India seeks to execute a Warrant to arrest a person or production of documents or things or all and such scheme requires to be executed in a Contracting State [other Country where the Accused or the Witness stays] then the Court that seeks such person or things or both may issue a Warrant in duplicate in such form to the Judge or Magistrate of that Court and send it through such Authority as the Central Government has notified and make it executed. 

While in the course of investigation by an Officer or his Superior Officer, it was found desirable to subject the person who is in a Contracting State for such investigation or to secure documents or things in his custody or in his power, and, if the Court is satisfied, it may issue Warrant or Summons to comply with the procedure established under Law by addressing to the concerned Magistrate or Judge to execute it on the person through the Central Government notified authority.
