law: Code of Criminal Procedure Act, 1973
  
  401.High Courts powers of revision.-
  (1) In the case of any proceeding the record
  
  of which has been called for by itself or which otherwise comes to its
  
  knowledge, the High Court may, in its discretion, exercise any of the powers
  
  conferred on a Court of Appeal by sections 386, 389, 390 and 391 or on a Court
  
  of Session by section 307 and, when the Judges composing the Court of revision
  
  are equally divided in opinion, the case shall be disposed of in the manner
  
  provided by section 392.
  (2) No order under this section shall be made to the prejudice of the accused
  
  or other person unless he has had an opportunity of being heard either
  
  personally or by pleader in his own defense.
  (3) Nothing in this section shall be deemed to authorize a High Court to
  
  convert a finding of acquittal into one of conviction.
  (4) Where under this Code an appeal lies and no appeal is brought, no
  
  proceeding by way of revision shall be entertained at the instance of the party
  
  who could have appealed.
  (5) Where under this Code an appeal lies but an application for revision has
  
  been made to the High Court by any person and the High Court is satisfied that
  
  such application was made under the erroneous belief that no appeal lies
  
  thereto and that it is necessary in the interests of justice so to do, the High
  
  Court may treat the application for revision as a petition of appeal and deal
  
  with the same accordingly.
