The binding legal principles established are: (1) An amicus curiae may, in appropriate circumstances where public interest is involved, have legal standing to seek leave to appeal, applying Campus Law Clinic factors including whether there is another reasonable and effective manner to bring the challenge, the nature of relief sought, vulnerability of affected persons, and nature of rights infringed. (2) The audi alteram partem principle is an indispensable condition of fair proceedings that must be observed regardless of whether hearing the other party would likely change the outcome - the 'no difference' approach is generally anathema to natural justice. (3) When exercising discretion to grant a postponement, a court must judicially exercise that discretion by considering all relevant factors including timeliness of application, full explanation, prejudice to all parties, opposition, and broader public interest - not just the interests of immediate parties. (4) A court's failure to allow parties opportunity to file answering affidavits and present evidence constitutes a miscarriage of justice and procedural unfairness. (5) However, the Constitutional Court will intervene in unconcluded lower court proceedings only in cases of great rarity where grave injustice threatens and intervention is necessary to attain justice - not where a matter is proceeding to hearing within a reasonable timeframe.
