Section 69. Revision

The Chief Commissioner may, either suo-moto or on an application, call for and examine the records of any proceedings in which no appeal lies to the Chief Commissioner under section 63 for the purpose of satisfying himself as to the legality or propriety of any decision, award or order made and if in any case it shall appear to the Chief Commissioner that any such decision, award or order should be modified, annulled or revised, the Chief Commissioner may, after giving the party to be affected thereby an opportunity of being heard, pass such order thereon as he may deem fit.
