Nothing in this Act, shall be deemed to limit or otherwise affect the inherent power of the Revenue Court to make such orders as may be necessary for the ends of justice or to prevent 1[or to correct]1 the abuse of the process of the Revenue Court.
[Provided that the inherent power to review may be exercised suo motu or on an application by petitioner or respondent in the case within a period of six months from the date of the order, on the discovery of new and important matter or evidence which was not within the knowledge of the Revenue Court when the order was made, or where some mistake or error apparent on the face of the record is found, including exercise of powers without jurisdiction or misapplication of legal provision or on any analogous ground not amounting to be an error on merit.]1
