The appellant, a local software development company, instituted action proceedings in 2008 against the respondent, a German software company, claiming damages of €609 803 145 for alleged unlawful interference with a software distribution agreement. In 2010, the respondent applied under s 13 of the Companies Act 61 of 1973 for security for costs. Although the 1973 Companies Act was repealed and replaced by the Companies Act 71 of 2008 (effective 1 May 2011) while the application was pending, the Full Court in 2012 ordered the appellant to furnish security of R4 million based on the transitional provisions. The appellant eventually furnished the security after unsuccessful appeals to the SCA and Constitutional Court. In 2018, the appellant applied to have the R4 million security released, alleging material changes in circumstances: (1) the repeal of s 13 of the 1973 Act (which had no equivalent in the 2008 Act), and (2) the joinder of its litigation funder, Ungani Investments, which allegedly had sufficient assets to cover adverse costs. The respondent simultaneously applied to confirm its right to increase the security amount and to join Ungani and its shareholder Mr Mufamadi in the main action.
