The appellant, Golden Fried Chicken (Pty) Ltd, was the franchisor of the Chicken Licken fast-food outlet. The first respondent, Sirad Fast Foods CC, was one of its franchisees. A franchise agreement was concluded on 24 October 1988, effective from 1 November 1988 for a period of ten years, with provision for a five-year extension subject to conditions including: (a) written notice by the franchisee at least six months before expiry, and (b) execution of a new agreement in the then-standard form. Sirad failed to give the required notice, and the initial agreement terminated on 31 October 1998. However, both parties continued their business relationship under exactly the same conditions: Sirad continued trading as a Chicken Licken outlet, making royalty payments, undergoing weekly quality control tests, receiving supplies, and even complied with the appellant's August 1999 request to renovate premises. On 25 August 1999, the appellant relied on the expired agreement and gave Sirad notice to cease trading as a Chicken Licken outlet by 1 October 1999. The appellant then sought an interdict to prevent Sirad from using its trademarks.
