Summers v The Commonwealth

In an action before the High Court of Australia, Charles Francis Summers and Ellen Peterson (as assignee) sued the Commonwealth for damages arising from the alleged wrongful refusal to accept marble supplied under a contract. Summers sought damages for breach of contract, alternatively a quantum meruit, and the return of a security deposit. Peterson, as assignee, also claimed the deposit and quantum meruit payment. The Commonwealth counterclaimed for damages for breach of a covenant against assigning the contract.

The central legal issues before the court were: first, whether the contract required the supply of marble blocks of specific dimensions from which the final pieces could be worked, or whether it permitted the supply of larger blocks from which multiple specified pieces could be cut; second, whether the plaintiff had demonstrated readiness and willingness to perform the contract according to its terms; and third, whether the parties, through their conduct, had mutually abandoned or abrogated the contract. The court also considered the validity of the plaintiff's claim for a quantum meruit and the entitlement to the return of the security deposit.

Isaacs J. held that the contract required the supply of marble blocks of dimensions sufficient to be worked and polished to the specified sizes, not larger blocks from which multiple specified pieces could be cut. This interpretation was based on the express wording of the specification and schedule, which were inconsistent with any implied trade usage permitting the latter method. The court found that the marble tendered by Summers did not comply with these requirements and was therefore rightly rejected. Furthermore, the evidence indicated that Summers was not ready and willing to perform the contract as interpreted by the Commonwealth, and that his persistent maintenance of an untenable construction of the contract was inconsistent with a continuing intention to observe his obligations. The court also concluded, based on the parties' conduct and correspondence, that the contract had been mutually abandoned or abrogated. Consequently, the claim for damages and quantum meruit failed.

The court ordered judgment for the plaintiff Peterson for £25, representing the return of the security deposit, on the basis that the contract had been terminated by mutual abandonment, which included the abandonment of the right to retain the deposit. On the Commonwealth's counterclaim for breach of the covenant against assigning, judgment was entered for the defendant for 1s., as the Commonwealth had indicated it would not press the counterclaim if no damages were awarded on the plaintiff's claim.
