The Commonwealth of Australia of Dept of Defence v East Coast Brokers Pty Ltd & Anor

The Commonwealth of Australia, Department of Defence, appealed to the High Court of Australia against a decision of the Full Federal Court concerning a dispute with East Coast Brokers Pty Ltd and another party. The core of the disagreement revolved around the interpretation and enforceability of a contract for the supply of goods, specifically relating to the Department's obligation to pay for services rendered by East Coast Brokers.

The High Court was required to determine whether the Department of Defence had validly terminated the contract and, consequently, whether it was liable to pay East Coast Brokers for services performed prior to the purported termination. A key issue was whether the Department's actions constituted a repudiation of the contract, thereby entitling East Coast Brokers to accept the repudiation and claim damages for breach of contract.

Callinan and Heydon JJ found that the Department's conduct, particularly its failure to make payments as stipulated by the contract and its subsequent communication, amounted to a repudiation of the agreement. Their Honours reasoned that the Department's persistent breaches of its payment obligations demonstrated an intention no longer to be bound by the essential terms of the contract. Consequently, East Coast Brokers was entitled to treat the contract as discharged and to sue for damages. The appeal was dismissed.
