  12. Power to appoint Joint Judges.-
  The Governor of Bombay in Council may, with the previous sanction of the Governor General of India in Council, appoint in any District a Joint Judge who shall be invested with co-extensive powers and a concurrent jurisdiction with the District Judge, except that he shall not keep a file of civil suits and shall transact such civil business only as he may receive from the District Judge, or as may have been referred to the Joint Judge by order of the High Court. When the appointment of a Joint Judge shall have been sanctioned by the Governor General of India in Council, the Governor of Bombay in Council may, so long as such sanction continues in force, appoint a successor to such Joint Judge in case his office becomes vacant, or transfer such Joint Judge from one District to another; and in such other District the Joint Judge so transferred shall have the same powers as he had in the former District.
