For an application for leave to appeal to succeed under section 17(1)(a)(i) of the Superior Courts Act 10 of 2013, the applicant must demonstrate reasonable prospects of success, meaning there must be a sound rational basis to conclude that a court of appeal could reasonably arrive at a different conclusion from the trial court. A mere possibility of success or an arguable case is insufficient. Where a party has been afforded a fair and reasonable opportunity to adduce evidence and make submissions on issues properly raised on the pleadings and argued by opposing parties, and where the party was represented by counsel with adequate resources and opportunity to respond, there is no breach of audi alteram partem even if the court's ultimate interpretation was not the party's preferred position. Issues are properly before the court when they are raised on the pleadings (including affidavits where those constitute the pleadings by agreement), canvassed in evidence, and argued by the parties.
