Hall v Busst

The High Court of Australia considered an appeal in *Hall v Busst*. The dispute concerned the interpretation and enforceability of a restrictive covenant contained within a deed of conveyance of land. The covenant purported to restrict the purchaser from using the land for any purpose other than a private dwelling house, and also stipulated that the vendor, or their successors in title, would have a right of pre-emption to repurchase the land at a specified price should the purchaser wish to sell. The purchasers sought a declaration that the covenant was void and unenforceable.

The central legal issues before the High Court were whether the restrictive covenant, in its entirety, was void for uncertainty and repugnance, and whether the right of pre-emption constituted an unlawful restraint on alienation. Specifically, the court had to determine if the covenant created an unreasonable fetter on the free disposition of the land, and if the terms of the pre-emption clause were sufficiently clear and certain to be legally effective.

The High Court, by majority, held that the covenant was void and unenforceable. The majority reasoned that the right of pre-emption, as drafted, imposed an unlawful restraint on the alienation of property. This was because the price stipulated for repurchase was fixed and did not take into account any potential increase in the land's value, thereby creating an unreasonable impediment to the owner's ability to sell the land on the open market. The court distinguished this from valid restrictive covenants that regulate the use of land, finding that the pre-emption clause went beyond mere regulation and amounted to an unlawful fetter on the fundamental right to dispose of property.

Consequently, the High Court allowed the appeal and ordered that the covenant be declared void and unenforceable.
