Macnamara v Martin

This case involved an appeal from the Supreme Court of New South Wales concerning a dispute between a hotelkeeper (the respondent) and a commission agent (the appellant). The agent had been employed to find a purchaser for the hotel's goodwill and lease on specific terms for a commission of £50. The agent introduced a ready and willing purchaser, but the hotelkeeper subsequently instructed the agent to cease dealings with that purchaser and offered new terms. Despite these instructions, the agent induced the purchaser to sign a contract on the original terms and claimed his commission. The hotelkeeper refused to pay, leading to the agent suing for commission and initially succeeding in the District Court. The Supreme Court, however, set aside this verdict.

The central legal issues before the High Court were whether the agent, having introduced a suitable purchaser before his authority was effectively revoked or altered, was entitled to remuneration despite subsequent actions that contravened the vendor's instructions, and whether the trial judge's direction to the jury was appropriate. Specifically, the court had to consider if the agent's actions after receiving new instructions constituted misconduct that disentitled him to any commission or damages, and if the jury should have been directed to consider a quantum meruit for services rendered rather than a fixed commission.

The High Court reasoned that the agent had fulfilled his contractual obligation by introducing a bona fide purchaser ready and willing to buy on the proposed terms before his authority was revoked. Therefore, he was entitled to remuneration, either the agreed commission if a sale had occurred, or a quantum meruit for the value of his services if no sale resulted. The court held that any subsequent actions by the agent, even if they prejudiced the principal, would not disentitle him to remuneration already earned, unless those actions caused damage to the principal. The court found that the trial judge's direction, while not perfectly precise as it did not explicitly account for a quantum meruit, was acceptable given that the entire contest at trial was whether the agent was entitled to the full £50 or nothing. The court also noted that the alleged misconduct occurred after the agent had earned his entitlement and did not cause demonstrable harm to the vendor.

Consequently, the High Court allowed the appeal, discharged the order of the Supreme Court, dismissed the motion for a new trial, and restored the judgment of the District Court. The respondent was ordered to pay the costs of the appeal.
