On 16 May 2006 the South African Transport and Allied Workers’ Union (SATAWU) organised a protest march in Cape Town arising from a strike in the security sector. The gathering, regulated under the Regulation of Gatherings Act 205 of 1993, degenerated into a riot causing extensive damage to vehicles, shops and property, and injury to individuals. Several affected individuals sued the Union in the Western Cape High Court for damages in terms of section 11 of the Act, which imposes statutory liability on organisers of gatherings that result in riot damage. SATAWU defended the action and raised a constitutional challenge to section 11(2)(b) of the Act, arguing that it imposed an onerous and illusory defence, infringing the right to freedom of assembly in section 17 of the Constitution. The High Court separated and determined the constitutional issue, rejecting the challenge. SATAWU appealed to the Supreme Court of Appeal.
