The Supreme Court adopted the Court of Appeal's
description of the position
under standard contract law (see Lord Clarke's judgment at para 20): ordinarily where the terms are in writing and there are no oral terms then the written terms will, prima facie, represent the whole of the parties» agreement; the parties are
bound by the written terms when they sign the contract; the written terms will stand unless they do not accurately reflect what was agreed because of a mistake (generally common to the parties); and no terms which conflict with the express terms can be implied into the contract.
