During 1998, a predecessor of the appellant Municipality concluded an agreement with Quill Associates (Pty) Ltd (Quill) to purchase a software program (the BIQ program) with annual support and maintenance. In 2004, a new agreement was entered into after a name change. In July 2011, the Municipality's predecessor gave notice to terminate the agreement but continued using the BIQ program on a month-to-month basis without paying licence fees. Quill instituted action in the High Court for copyright infringement under section 24(1) of the Copyright Act 98 of 1978. On 31 July 2015, the trial court (Potterill J) found copyright infringement and granted interdictory relief plus a monetary judgment for reasonable royalty with 'interest on the said amounts at a rate of 15.5% per annum ad tempore morae; VAT if VAT is payable on the amounts so ordered.' The appellant made certain payments. Quill then caused a writ of execution to be issued by the Registrar for the balance outstanding, claiming interest from date of service of summons calculated and compounded monthly, and including VAT. The Deputy Sheriff executed the writ on 10 July 2018, attaching R7,965,470.56 from the Municipality's bank account. The Municipality applied to set aside the writ on the basis that it was not in accordance with the trial court order, particularly regarding the date from which interest ran, compound interest, and VAT.
