What is not at issue here is the Constitutional right of Witches to identify as Witches, to profess to have knowledge of Witchcraft, and to practice Witchcraft.
The Constitutional rights to freedom of religion, belief and association, do not protect any right to practice magical rituals designed to curse others, whether to protect an innocent from harm, or to avenge a wrong. The Witchcraft Suppression Act prohibits the practice of harmful magic intended to curse another.
South African law expressly prohibits the practice of magic in such a way as to cause harm, or to harass another in such a way as to inspire the reasonable belief that harm may be caused, or to utter or convey a threat which might induce a fear of being harmed through the use of witchcraft.
