Section 17(2)(f) of the Superior Courts Act 10 of 2013 operates as a proviso that takes exceptional cases out of the general rule that decisions of two judges refusing leave to appeal are final. The existence of "exceptional circumstances" is a jurisdictional fact and prerequisite that must be established before the President of the Supreme Court of Appeal may exercise discretion to refer a refusal of leave to appeal to the full Court for reconsideration. "Exceptional circumstances" means something out of the ordinary, uncommon, rare or different - something excepted from the general rule. The threshold is higher than that for ordinary leave to appeal or special leave to appeal. The provision is not intended to afford disappointed litigants a further opportunity to re-argue matters already considered and rejected, but rather to prevent grave injustice where matters of importance may have been overlooked. Where arguments merely rehearse contentions already advanced, considered and rejected, and there are no reasonable prospects of success, no important legal question, no factual dispute requiring reconsideration, no manifest denial of justice, and no special public significance, exceptional circumstances are not established and the application must fail.
