Attachmate Corporation, a US-based software supplier, entered into a software licence agreement and a related maintenance and support agreement with the Department of Water and Environmental Affairs in June 2005. The Department initially acquired 300 licences for Attachmate’s software and later regularised a further 360 licences, totalling 660 licensed copies. Despite contractual prohibitions, the Department continued to install and use additional copies without obtaining licences. An audit conducted by KPMG in 2009 revealed 1 564 unlicensed copies. Attachmate claimed licence fees for these unlicensed copies under an audit clause in the licence agreement and also claimed maintenance fees for the same copies under the maintenance agreement. The High Court limited the licence fee to a discounted rate and dismissed the maintenance fee claim. Attachmate appealed to the Supreme Court of Appeal.
