Miller Street Pty Ltd v Porter

The case of Miller Street Pty Ltd v Porter was heard by the Supreme Court of Queensland. The plaintiff, Miller Street Pty Ltd, a property development company, sought compensation from the defendant, Porter, for the cost of a driveway constructed on land owned by the plaintiff. Porter, a neighbour, had requested the construction of the driveway, but later refused to pay for it, leading to the plaintiff's claim for the outstanding amount.

The primary legal issue before the court was whether Porter was liable for the cost of the driveway under the doctrine of promissory estoppel or whether the absence of a formal contract negated any obligation to pay. The court had to consider if Porter's conduct in requesting the construction and the plaintiff's reliance on this request could create a binding agreement in the absence of a written contract.

The court found that Porter's request for the driveway, coupled with the plaintiff's reliance on this request in proceeding with the construction, created a binding agreement. The principle of promissory estoppel was applicable, preventing Porter from going back on his request. The court determined that Porter was liable for the cost of the driveway. However, the court also noted that the defendant's right of indemnity would be limited to half of his costs in the proceedings. The plaintiff was awarded compensation in the sum of $29,047.33, with no order for costs, and the defendant's right of indemnity was limited to half of his costs of this proceeding.
