A challenge to a criminal conviction on the basis that a guilty plea was improperly induced raises a question of law and must be pursued by way of appeal rather than review. A review application under the court's general powers of review must comply with the procedural requirements of Order 33 r 256 of the High Court Rules, including proper citation of respondents and clear statement of grounds for review. For a review to succeed on grounds of irregularity, the irregularity must be so gross as to vitiate the proceedings and be apparent ex facie the record. Where an applicant challenges the conviction itself rather than the propriety of the procedure used by the magistrate, the appropriate remedy is appeal, not review.
