The binding legal principles established are: (1) Leave to appeal should be granted where there is a sound, rational basis for the conclusion that there are realistic prospects of success on appeal; (2) The right to a fair trial under section 35(3) of the Constitution can constitute a valid ground for granting leave to appeal, even if not previously raised as a ground before the lower court; (3) A judicial officer must conduct trials in a manner that demonstrates both subjective and objective impartiality - fairness and impartiality must be both subjectively present and objectively demonstrated to the informed and reasonable observer; (4) A presiding officer should not question witnesses in a manner that may intimidate or disconcert them, unduly influence the quality or nature of their replies, or impair their credibility; (5) Where the conduct of a trial sustains the inference that the presiding judge was not open-minded, impartial, or fair, an appellate court may intervene and grant appropriate relief; (6) Judicial officers must accord all officers of the court, witnesses, and accused persons the dignity and respect they are entitled to; (7) While judicial officers are not passive umpires and may intervene to ensure fairness and justice, it is only when prejudice is caused to an accused that intervention becomes an irregularity that vitiates proceedings.
