The appellants were the only two trustees of a family business trust. The first appellant, acting alone and without the written authority or participation of the second trustee, concluded an advance contract on 9 May 2001 for the sale of 900 tons of yellow maize to a close corporation. The contract was later ceded to the respondent, Vrystaat Mielies (Edms) Bpk. The trust deed required unanimous decisions where there were two trustees. When maize prices rose sharply, the trustees refused to perform, alleging that the contract was null and void because the first trustee lacked authority to bind the trust. The respondent sought to enforce the contract, relying inter alia on the Turquand rule.
