Heonig agreed to decorate Isaacs's flat for £750. Isaacs was not satisfied with the work, and offered only £400, so Hoenig sued for the balance. Isaacs claimed that the contract was for the whole job, and Hoenig had not finished it properly. At most, it was argued, he was entitled to an award of QuantumMeruit for the work done. However, the court ruled that the contract was substantially complete, and the Hoenig should be paid the full price less the amount it would cost to finish the job (estimate at £55).
