The Anshun principle applies to preclude parties from raising grounds in administrative review proceedings that could and should have been raised in earlier proceedings, including allegations of fraud discovered through failure to read earlier tribunal reasons. A party's failure to read reasons for decision, whether through negligence, inadvertence or accident, constitutes the kind of omission contemplated by the Anshun principle. The Tribunal's obligation under s 42B(1) is to determine whether the application before it is itself frivolous or vexatious, not merely whether there is a long history of litigation.
