The binding legal principles established are: (1) In passing-off claims, proof requires establishing reputation, misrepresentation, and damage. (2) Reputation can be inferred from evidence of sales, advertising, longevity of trading (27 years in this case), substantial turnover (R30 million annually), and marketing expenditure (R100,000 annually). (3) A robust and common sense approach should be adopted when assessing whether reputation has been established. (4) Bare denials unsupported by evidence are insufficient to create a genuine dispute of fact in passing-off applications, particularly where the disputing party must necessarily possess knowledge of the factual matrix to provide a countervailing answer. (5) Continuing to trade under a name that is deceptively similar to an established business's name, despite undertakings to cease doing so and formal changes to the registered company name, constitutes unlawful passing-off. (6) Evidence of actual customer confusion (such as misdirected purchase orders) supports a finding of passing-off. (7) Concessions by the alleged infringer that confusion is likely (as evidenced by undertakings to change the name 'to avoid confusion') supports a finding of misrepresentation. (8) A business that has established reputation in its name is entitled to protection from having its reputation placed at the mercy of parties who have wrongly conducted themselves so as to cause confusion.
