The parties concluded a written contract on 6 August 2004 for the sale and delivery of groundnuts at R4 300 per ton. The contract described the goods as “hand cleaned farmer’s grade groundnuts”. Amanita Premier Oils Ltd (the supplier/plaintiff) delivered 926.54 metric tons, of which the buyer, Praysa Trade 1069 CC t/a Jumbo Peanuts (the defendant), used or on-sold most, rejecting only two loads and setting aside about 40 tons. The defendant paid part of the invoiced amount but withheld the balance, alleging that the groundnuts were of sub-standard quality, contained wet and mouldy bags, and had unacceptable aflatoxin levels. The plaintiff sued for the outstanding balance. The High Court granted absolution from the instance, finding that the plaintiff had failed to prove that the goods complied with the agreed quality. The plaintiff appealed to the Supreme Court of Appeal.
