1. Section 7(2) of the Admission of Advocates Act 74 of 1964 does not unconstitutionally grant a society of advocates jurisdiction over non-member advocates; it merely confers standing to apply to court for disciplinary action, with disciplinary powers remaining with the court. 2. When a constitutional matter involves the development of the common law rather than direct application of constitutional provisions, it is ordinarily not in the interests of justice for the Constitutional Court to exercise direct appellate jurisdiction without the matter first being considered by the Supreme Court of Appeal, which has expertise in common law matters. 3. The regulation of the legal profession and determining the fitness of members to practice is a matter in respect of which the Supreme Court of Appeal has inherent common law jurisdiction and particular expertise. 4. Under section 167(6) of the 1996 Constitution, leave to appeal directly to the Constitutional Court requires demonstration that it is in the interests of justice to do so, considering factors beyond mere constitutional characterization, including the nature of the dispute and the appropriate forum for its resolution.
