KLD Residential CC (the appellant) was given a written mandate in November 2006 to market properties in a development by Empire Earth Investments 17 (Pty) Ltd (the respondent), with commission payable upon transfer. KLD claimed R2.147 million in commission for 99 sales with transfers registered between October 2008 and November 2009. KLD issued summons in June 2013. Empire Earth raised a special plea of prescription, as more than three years had elapsed since the registration dates. On 29 July 2011, Empire Earth's attorneys wrote a 'without prejudice' letter to KLD's attorneys during settlement negotiations, acknowledging that KLD was entitled to commission of R2,105,960, and offering to settle all claims with a cheque for a reduced amount after set-off. The cheque was not banked. KLD argued that this letter constituted an acknowledgment of liability under s 14 of the Prescription Act 68 of 1969, which interrupted prescription and caused it to run afresh from that date. The matter came before the Western Cape High Court by way of a stated case on whether an acknowledgment of liability in a 'without prejudice' communication could be admitted in evidence solely for the purpose of interrupting prescription.
