The Micro Finance Regulatory Council (the appellant) was a section 21 company incorporated as a private regulator for the micro-lending industry. In 1999, the Minister of Trade and Industry issued an exemption notice under section 15A of the Usury Act 73 of 1968, exempting micro-lending transactions from interest rate restrictions on condition that lenders register with an approved regulatory institution. The Minister approved the appellant as such an institution. The appellant's memorandum of association empowered it to make and enforce rules to be complied with by registered micro-lenders. Lenders who registered with the appellant contractually agreed to abide by both the ministerial exemption notice and the appellant's rules. The first respondent, AAA Investment (Pty) Limited, was a micro-lender that registered with the appellant. In June 2001, the appellant introduced revised rules including requirements for lenders to submit data to a national loans register and to satisfy themselves that borrowers could make repayments before granting loans. The first respondent objected and launched an application in the Pretoria High Court to invalidate both the initial and revised rules on constitutional grounds, arguing that the appellant was purporting to exercise public regulatory powers without legislative authority, and that the data submission requirement violated the constitutional right to privacy under section 14.
