appointment of commiosner

I am assuming you're asking about appointment of law commissioner. So here is the process -

The provisions relating to appointment of Commissioner is set out in Civil Procedure code. Under “Incidental proceedings” section 75 and Order XXVI Rules 1 to 22 of the Code deal with it. The aspect of Advocate Commissioner is dealt under section 75 and Order XXVI rule 9 of Code. Civil Rules of Practice from rules 134 to 141 also deal with it. As per section section 75 of the Code subject to conditions and limitations as may be prescribed, the court may issue a commission in following aspects namely –
 a) To examine any person;
 b) To make a local investigation;
 c) To examine or adjust accounts; or
 d) To make a partition;
 e) To hold a scientific, technical, or expert investigation;
 f) To conduct sale of property which is subject to speedy and natural decay
 and which is in the custody of the Court pending the determination of the
 suit.
