For purposes of this application for leave to appeal: (1) The test for granting leave to appeal under section 17(1)(a)(i) of the Superior Courts Act requires that the judge be of the opinion that the appeal would have a reasonable prospect of success, meaning there must be a sound rational basis to conclude that a court of appeal could reasonably arrive at a different conclusion; (2) An issue is properly before the court if it is raised on the pleadings (which in this case were constituted by the affidavits in the intervention application), canvassed in evidence, and addressed in submissions; (3) The audi alteram partem principle requires that parties be afforded a fair and reasonable opportunity to state their case, including the opportunity to lead evidence and make submissions on issues properly raised on the pleadings; (4) Where parties are represented by counsel, have ample opportunity to lead evidence and make written and oral submissions, including post-hearing submissions, and the issue is squarely raised on the pleadings and addressed by opposing parties, there is no violation of audi alteram partem even if a party does not extensively develop arguments on a particular point.
