The binding legal principles established are: (1) A superior court will only exercise its review powers over unterminated proceedings in exceptional cases where grave injustice might otherwise result or where justice might not by any other means be attained; (2) A trial officer's indication that detailed reasons for dismissing a discharge application will be provided in the final judgment does not constitute a gross irregularity or procedural impropriety warranting review; (3) The proper procedure for challenging police disciplinary proceedings is to complete the trial and thereafter utilize sections 31-34 of the Police Act for review or appeal, rather than seeking review of interlocutory rulings; (4) Review proceedings concern the validity and method of trial, not the correctness of decisions on facts or law, which are matters for appeal; (5) Section 198(3) of the Criminal Procedure and Evidence Act applies to police disciplinary proceedings by virtue of section 35(1) of the Police Act, which requires proceedings to be as near as may be the same as those prescribed for criminal cases in courts.
