SACTWU Investments Group (Pty) Ltd (SIG) lent R150 million to Sekunjalo Independent Media (Pty) Ltd (SIM) in August 2013 under a loan agreement providing for quarterly interest, with unpaid interest to be capitalised. No interest was paid, and by 2017 SIG sought to exit the loan. This coincided with plans by SIM and its holding company to merge assets into Sagarmatha Technologies Ltd, intended to list on the JSE and NYSE. A sale agreement was concluded in November 2017 for SIG’s loan claim and shares in SIM to be exchanged for Sagarmatha shares, subject to listing. Around the same time, a subordination agreement was signed by Mr Andre Kriel, a director of SIG, subordinating SIG’s loan claim in favour of other creditors until SIM’s assets exceeded its liabilities. The Sagarmatha listing failed, the sale agreement became ineffective, and the loan was not repaid. SIG sued for repayment. SIM relied on the subordination agreement as a defence, contending that SIG could not enforce the loan until solvency was restored. SIG disputed the validity of the subordination agreement, alleging lack of authority, mistake or misrepresentation, and also disputed the application of the in duplum rule to capitalised interest.
