When the Supreme Court of Appeal refuses leave to appeal, an application for leave to appeal to the Constitutional Court is not an appeal against the SCA's refusal but an appeal against the original High Court decision itself, and therefore rule 18 (not rule 20) of the Constitutional Court rules applies. The question of whether democratically elected municipal council members should be held personally liable for costs arising from their conduct during council deliberations is a constitutional matter that engages: (1) the constitutional protection of privileges and immunities for municipal council members under section 161 of the Constitution and section 28 of the Local Government: Municipal Structures Act; (2) freedom of speech of members of elected deliberative bodies; and (3) the constitutional principle of separation of powers between the judiciary and the legislative and executive branches of government.
