Where an appeal procedure is prescribed by statute or regulation with specific procedural steps, strict compliance with those procedures is mandatory for a valid appeal to exist. In the context of the Police (Trials and Boards of Inquiry) Regulations, 1965, an appellant must give notice of intention to appeal to the Officer Commanding within 24 hours and lodge written notice with grounds of appeal with the Officer Commanding within seven days. Failure to follow this prescribed procedure means there is no valid appeal, and consequently, the automatic suspension provisions of section 51 of the Police Act cannot apply. An application for a declaratur is not the appropriate remedy where the substantive relief sought (such as reinstatement following discharge) is more properly the subject of review proceedings.
