Grounds for review under Order 33 rule 257 of the High Court Rules must be stated shortly and clearly, but applicants are not required to use the exact wording of section 27 of the High Court Act. A ground for review is "clear" when it portrays an obvious meaning, is devoid of ambiguity, is easily understood from the plain language used, and is free from confusion. The failure to use exact statutory wording does not render a review application fatally defective, provided the grounds are otherwise short and clear and fall within the recognized grounds for review under section 27 of the High Court Act.
