The appellant bank (FirstRand Bank) advanced a loan of R2.1 million to the second and third respondents (the Maharajs) in September 2006 to purchase immovable property secured by a mortgage bond. The monthly instalment was R20,335.07, inclusive of interest at 10.05% per annum, which was variable. In 2010, the Maharajs applied for debt review under section 86 of the National Credit Act 34 of 2005 (NCA). On 25 November 2011, the magistrate's court granted a debt review order under section 86(7)(c)(ii) of the NCA, declaring the respondents over-indebted and reducing their monthly instalments to R8,185.50 per month with the period extended to 261 months at an interest rate of 12.55% per annum. However, this monthly instalment was insufficient to cover even the monthly interest (which would have been approximately R22,000 per month), let alone reduce the capital debt. The respondents complied with this order until June 2017. Following the judgment in Nedbank Limited v Jones (2017 (2) SA 473 (WCC)), which held that such debt review orders were void, the bank applied for rescission of the debt review order on the basis that it was void ab origine. The magistrate granted the rescission, which was appealed to the High Court. The High Court set aside the magistrate's rescission order, leading to this appeal to the Supreme Court of Appeal.
