The case arose from a criminal prosecution in which a father was convicted in the Johannesburg Magistrates’ Court of assaulting his 13-year-old son. On appeal, the Gauteng Local Division of the High Court, mero motu, declared the common law defence of reasonable and moderate parental chastisement unconstitutional, holding that it infringed children’s constitutional rights. None of the original parties challenged this declaration. Freedom of Religion South Africa, which had participated as amicus curiae in the High Court, sought standing to intervene and applied directly to the Constitutional Court for leave to appeal against the declaration of invalidity, arguing that parents should retain a defence allowing reasonable and moderate corporal punishment grounded in common law, culture, and religion.
