The appellants, owners or assignees of copyright in the musical work ‘Umoja’, sued the respondents in the South Gauteng High Court for copyright infringement. They alleged infringements both within South Africa (relying on the Copyright Act 98 of 1978) and in 19 foreign countries, relying on the copyright laws of those countries. The respondents raised an exception, contending that South African courts lacked jurisdiction to adjudicate alleged infringements of foreign copyright. The High Court upheld the exception in respect of the foreign copyright claims, and the appellants appealed to the Supreme Court of Appeal.
