The binding legal principles established are: (1) An application for the Constitutional Court to delay handing down judgment in matters already heard and decided, in order to hear arguments in a related case brought by a party that was aware of but did not participate in the original proceedings, will not be granted in the absence of compelling justification; (2) A party seeking to participate in constitutional litigation of which it is aware must utilize proper procedures such as applying for admission as amicus curiae under rule 9, and cannot circumvent this by later seeking to delay judgment; (3) In determining whether to grant leave to appeal directly to the Constitutional Court, the critical issue is an evaluation of what is in the interests of justice, with key considerations including whether the issues raise constitutional matters of importance, whether direct appeal will result in saving of costs and time, and whether the Constitutional Court is the appropriate forum for final determination; (4) Where a positive certificate has been granted under rules 18(2) and 18(6), constitutional issues of fundamental importance to a statutory scheme are raised, and expeditious finality is necessary to remove uncertainty, these factors support granting leave to appeal directly to the Constitutional Court; (5) Where judgment in related proceedings may affect the issues on appeal, an applicant should be given opportunity to supplement its application to define the matters it wishes to pursue.
