Laugh It Off Promotions CC produced and sold T-shirts for profit bearing altered versions of South African Breweries’ well-known CARLING BLACK LABEL trade marks. The alterations replaced the original wording with phrases such as “Black Labour”, “White Guilt” and “Africa’s lusty lively exploitation since 1652”, conveying social and political criticism. SAB, the registered trade mark owner, contended that this unauthorised use in the course of trade diluted and tarnished its marks in contravention of section 34(1)(c) of the Trade Marks Act 194 of 1993. The High Court granted an interdict against Laugh It Off, and the Supreme Court of Appeal upheld the finding of infringement. Laugh It Off sought leave to appeal to the Constitutional Court, relying on the constitutional right to freedom of expression under section 16 of the Constitution.
