Tinker Tailor Pty Ltd v Commissioner for Main Roads

Tinker Tailor Pty Ltd (the appellant) appealed to the High Court of Australia against a decision of the Supreme Court of New South Wales, which had upheld a determination by the Commissioner for Main Roads (the respondent) that the appellant was liable to pay compensation under the *Main Roads Act 1924* (NSW) for the resumption of certain land. The dispute concerned the quantum of compensation payable for the compulsory acquisition of land for road purposes.

The central legal issue before the High Court was whether the appellant was entitled to compensation for the loss of a specific business advantage, namely the potential to develop the resumed land in conjunction with adjoining land owned by the appellant, for the purpose of a drive-in theatre. This involved determining whether such a potential advantage, which was not yet realised and depended on future planning and approvals, constituted an element of "market value" for the purposes of compensation under the relevant legislation.

The High Court, in a joint judgment, held that the compensation payable under the *Main Roads Act 1924* (NSW) was to be assessed by reference to the market value of the land at the date of resumption, taking into account all circumstances which would affect that value in the eyes of a willing purchaser. However, the court distinguished between the inherent potential of the land itself and a speculative advantage derived from the owner's other holdings. The court found that while the potential for development was a relevant consideration, the specific advantage of combining the resumed land with adjoining land for a drive-in theatre was too remote and speculative to be included in the market value. The reasoning was that the value of the land should reflect what a willing purchaser would pay for it as it stood, with its existing potential, rather than for a future, hypothetical development that was contingent on factors beyond the land itself.

The appeal was dismissed.
