Hoenig v Isaacs [1952]

Hoenig v Isaacs [1952] EWCA Civ 6 is a notable English contract law case that delves into the concept of substantial performance of an entire contractual obligation.

Mr Hoenig had undertaken the task of decorating and furnishing Mr Isaacs' flat for a contracted sum of £750. Upon completion of the work, issues arose with a bookcase and wardrobe, requiring an additional expenditure of £55 for rectification. Mr Isaacs, however, refused to pay the outstanding amount of £350.

The judgment, delivered by Somervell LJ, upheld the decision of the Official Referee, His Honour Sir Lionel Leach, who initially heard the case. Somervell LJ emphasised the case's dependency on the construction of the contract and found that substantial compliance had indeed occurred. He clarified that when there is substantial performance of the contract, payment is mandatory. In this context, the completion of the work had taken place, and the issues with the bookcase and wardrobe constituted a damages claim rather than a failure to fulfill the contract. While acknowledging that the case was close to the borderline of substantial performance, Somervell LJ dismissed the appeal.

Denning LJ, in his judgment, also rejected the appeal and provided additional insights into the interpretation of contracts involving specific sums to be paid upon the completion of specified work. He argued against a construction that would entirely deprive the contractor of payment due to defects or omissions. Denning LJ emphasised that the promise to complete the work should be viewed as a term of the contract, not as a condition. Not every breach of this term absolves the employer from the obligation to pay the agreed price. Only breaches that go to the root of the contract, such as an abandonment of the work when only partially completed, would allow the employer to resist payment. In cases where the breach does not go to the core of the matter, the employer is obligated to pay the agreed price but may bring a cross-claim for the defects or set them up to diminish the price. Denning LJ explained that the measure for such situations is the amount by which the work's value is diminished due to the defects and omissions, typically calculated by the cost of rectification.

In summary, the court affirmed that substantial performance was sufficient to entitle the contractor to payment, allowing for deductions for defects. The judges stressed the principle that not every breach would absolve the employer from their payment obligation, and the measure of compensation would be the amount the work was diminished by the defects and omissions. The parties, however, retained the ability to make entire performance a condition precedent through express contractual terms.
