6.9.3 Grounds for review
A review can be filed by any person aggrieved by an order or decree of the Controller or court from which an appeal is allowed, but no appeal has been preferred, or from which no appeal is allowed:
and who, from the discovery of new and important matter or evidence which, after the exercise of due diligence was not within his knowledge or could not be produced by him at the time when the decree was passed or order made, or on account of some mistake or error apparent on the face of the record or for any other sufficient reason, desires to obtain a review of the decree passed or order made against him.239
An application for review must be accompanied by a statement setting forth the grounds on which the review is sought. Where the decision in question concerns any other person in addition to the applicant, the Controller shall forthwith transmit a copy of the application and the statement to the other person concerned.
