Application where rejected

4. Application where rejected.—(1) Where it appears to the Court that there is not sufficient ground for a review, it shall reject the application.
(2) Application where granted.—Where the Court is of opinion that the application for review should be granted, it shall grant the same:
Provided that—
(a) no such application shall be granted without previous notice to the opposite party, to enable him to appear and be heard in support of the decree or order, a review of which is applied for; and
