Paulsen and Another v Slip Knot Investments 777 (Pty) Limited

Winskor 139 (Pty) Ltd, a company whose shares were held by trustees of the Paulsen Family Trust, sought finance to purchase properties in Brooklyn, Pretoria, for resale at a profit. In 2006 Winskor concluded a loan agreement with Slip Knot Investments 777 (Pty) Ltd, a provider of short-term bridging finance to large-scale property developers. Slip Knot advanced R12 million to Winskor repayable within 12 months with interest at 3% per month from the seventh month. The Paulsens (Ms Margaretha Paulsen and Mr André Paulsen) bound themselves as sureties and co-principal debtors with Winskor. Due to an economic downturn in 2007, Winskor defaulted. By the time litigation commenced on 10 January 2010, interest had accumulated to R12 million (capped by the in duplum rule). Slip Knot claimed the capital sum plus interest, and further interest at 3% per month from institution of proceedings to judgment. The Paulsens defended on three grounds: (1) the loan agreement was invalid because Slip Knot was not registered as a credit provider under the National Credit Act 34 of 2005; (2) the in duplum rule limited interest to R12 million; and (3) as sureties, their liability could not exceed that of the principal debtor against whom no proceedings were instituted.

• Whether Slip Knot was required to register as a credit provider under section 40 of the National Credit Act 34 of 2005, despite providing loans that fell within the exclusions in section 4 of the Act
• Whether failure to register as a credit provider rendered the loan agreement invalid under sections 40(4) and 89(2)(d) of the National Credit Act
• Whether the in duplum rule, which caps accumulated interest at an amount equal to the capital debt, applies during the pendency of litigation (pendente lite)
• Whether the decision in Oneanate v Standard Bank of South Africa Ltd 1998 (1) SA 811 (SCA), which held that the in duplum rule is suspended during litigation, should be overruled
• Whether sureties can be held liable for more interest than the principal debtor when proceedings have not been instituted against the principal debtor
• Whether post-judgment interest runs at the contractual or statutory rate, and on what amount

1. Leave to appeal granted. 2. The orders of the Western Cape High Court, Cape Town dated 24 February 2012 and 12 February 2013 are set aside. 3. The appeal against the Supreme Court of Appeal order is upheld only to the extent reflected in paragraph 4. 4. The applicants (Paulsens) are ordered to pay the respondent (Slip Knot), jointly and severally: (a) R12 million (capital); (b) interest on that sum at 3% per month from 21 July 2007 to 10 January 2010, capped at R12 million; (c) interest on R24 million at 3% per month from 24 March 2015 (date of judgment) to date of payment, capped at R24 million. No order as to costs in all courts.

1. Under section 167(3)(b)(ii) of the Constitution, this Court has jurisdiction where a matter raises an arguable point of law (one with some prospects of success), of general public importance (transcending the parties and affecting a significant part of the public), which ought to be considered by the Court (in the interests of justice). 2. Section 40(1) of the National Credit Act requires registration only by credit providers whose business involves credit agreements subject to the Act; credit providers who exclusively provide loans falling under the section 4 exclusions need not register. 3. Section 89(2)(d) of the NCA, which renders credit agreements unlawful where the credit provider is unregistered, applies only to credit agreements "to which the Act applies", not to excluded agreements under section 4. 4. The in duplum rule, which caps accumulated arrear interest at an amount equal to the outstanding capital, continues to apply during the pendency of litigation (pendente lite), contrary to the holding in Oneanate. 5. Where competing public policy considerations do not clearly indicate the proper development of the common law, courts should defer to the Legislature to avoid usurping the legislative function in violation of separation of powers. 6. The suspension of the in duplum rule pendente lite impermissibly inhibits debtors' constitutional right of access to courts under section 34 by potentially subjecting them to financially ruinous interest accumulation merely for defending claims in good faith. 7. Post-judgment interest runs from the date of judgment of the final court (Constitutional Court) at the contractual rate on the whole judgment debt, capped by the in duplum rule at an amount equal to the judgment debt.

The majority judgment noted that South Africa's socio-economic realities involve vast capital disparities, with most credit consumers being far less financially resourced than large corporate credit providers. The judgment observed that entrepreneurship and economic advancement of those previously disadvantaged is essential for a meaningful democracy. The majority commented that while some debtors may be "stout-boned" and financially sophisticated, many are not, and even apparently strong borrowers may be financially precarious. The Court noted that mechanisms such as summary judgment and punitive costs awards exist to address vexatious litigation by debtors. The majority observed that uncapped interest pendente lite could incentivise creditors to abuse the litigation process against financially endowed debtors. The Court emphasized that the in duplum rule fulfills an economic function of helping debtors in financial distress and is far from an anachronism in daily economic life. The concurring judgment (Moseneke DCJ) noted that even after a court develops the common law, Parliament remains free to alter it provided the change does not offend the Constitution. The dissent (Cameron J) emphasized that contractual autonomy advances constitutional values of freedom and dignity, and that the capacity to contract freely must have its place in common law development. The dissent noted that the in duplum rule came into operation when credit markets functioned differently and inflation was much lower than today. The dissent observed that before Oneanate, the rule imposed costs on lenders by allowing inflation to erode the value of debts during litigation.

This case is the first by the Constitutional Court to grant leave to appeal under section 167(3)(b)(ii) (arguable point of law of general public importance) following the Constitution Seventeenth Amendment Act. The Court established criteria for determining when it has jurisdiction under this provision, including that the point must be arguable (have some prospects of success), be of general public importance (transcending the parties' interests and affecting a significant part of the public), and ought to be considered by the Court (interests of justice). The judgment clarifies the interpretation of sections 4, 40 and 89 of the National Credit Act regarding registration requirements and the validity of credit agreements. Most significantly, it overrules the long-standing precedent in Oneanate regarding the suspension of the in duplum rule during litigation. The majority held that courts should not develop the common law where competing public policy considerations do not clearly indicate the proper path, as this would usurp the legislative function and violate separation of powers. The case emphasizes that the constitutional right of access to courts (section 34) must be considered when developing common law rules affecting litigation. It also illustrates the Court's approach to developing the common law under section 39(2) of the Constitution, with different views expressed on when and how such development is appropriate. The judgment provides important guidance on balancing contractual autonomy (pacta sunt servanda) with consumer protection and access to justice in commercial lending relationships.
