Mayor, Councillors and Burgesses of the Town of Williamstown v Box

The Mayor, Councillors and Burgesses of the Town of Williamstown (the Municipality) appealed to the High Court of Australia from a decision of the Supreme Court of Victoria. The Municipality had sued Percy Harold Box to recover costs associated with the construction of Home Road, a street set out on private land. Mr. Box defended the claim by alleging an agreement with the Municipality that his liability would be determined by the outcome of a test case brought against another landowner on the same street, which had been decided in favour of that other landowner.

The legal issues before the High Court were whether a binding agreement existed between the Municipality and Mr. Box that would preclude the Municipality from pursuing its claim, and if so, the scope of that agreement. The Supreme Court had found that such an agreement existed and barred both of the Municipality's alternative claims against Mr. Box. The High Court was therefore required to determine the existence and effect of this alleged agreement.

The High Court, comprising Isaacs and Higgins JJ., found that the evidence did not establish a binding agreement between the Municipality and Mr. Box. Their Honours reasoned that the arrangement, while practical for managing potential litigation, was merely a loose, informal business arrangement and lacked the certainty and intention required to form a legally binding contract. The Court noted the vagueness of the evidence regarding the terms of any such agreement, the lack of express commitment from the Council, and the informal nature of the discussions. Consequently, the Court concluded that the defence based on the alleged agreement failed.

By consent of the parties, the appeal was allowed, and the judgment of the County Court was varied. Judgment was entered for the Municipality on its second alternative claim, relating to a special improvement charge, including interest. Each party was ordered to bear its own costs in all courts.
