The Minister of Trade and Industry, acting under s 15A of the Usury Act 73 of 1968, exempted certain micro-lending transactions from the Act on condition that lenders register with an approved regulatory institution. The appellant, the Micro Finance Regulatory Council (a s 21 company), was approved as such a regulatory institution. Its memorandum of association empowered it to make and enforce rules binding on registered micro-lenders. Lenders who registered contractually undertook to comply with the Council’s rules. The Council introduced revised rules, including a requirement that lenders submit loan information to a national loans register. The first respondent, a registered micro-lender, objected to the revised rules and applied to the High Court to have both the initial and revised rules set aside, arguing that the Council was unlawfully exercising public legislative power without statutory authority and that certain rules infringed the constitutional right to privacy. The High Court upheld the challenge and set aside the rules, leading to an appeal to the Supreme Court of Appeal.
