Specialist Diagnostic Services Pty Ltd v Healthscope Ltd

Specialist Diagnostic Services Pty Ltd brought an action against Healthscope Ltd concerning a lease agreement for premises in a hospital, where Healthscope was the landlord and Specialist Diagnostic Services was the tenant operating a pathology laboratory. The dispute arose when Healthscope sought to alter the physical form of the hospital premises, which Specialist Diagnostic Services argued would interfere with their business operations and breach a restraint of trade clause in the lease. The case was heard in the Supreme Court of New South Wales.

The primary legal issues before the court were whether the restraint of trade doctrine applied to the lease of premises in a hospital to a pathology laboratory, the reasonableness of the restraint, and the implications of Healthscope's proposed alterations on the tenant's business. The court also needed to determine whether the restraint clause could be enforced and, if so, whether it could be modified under the Restraint of Trade Act 1976 (NSW). Additionally, the court considered whether an implied term regarding the non-derogation from the grant of the leased premises could be read into the lease.

The court found that the restraint of trade doctrine was applicable in this context, as the lease restricted Healthscope from carrying on a similar business to that of Specialist Diagnostic Services. The restraint was deemed reasonable as it protected a legitimate interest of the covenantee. The court held that the restraint clause in the lease ran with the land and was enforceable. However, it was necessary to read down the restraint clause to prevent it from being substantially detrimental to Specialist Diagnostic Services' business. The court also found that Healthscope's proposed alterations to the hospital premises constituted a breach of an implied term not to derogate from the grant and would interfere substantially with Specialist Diagnostic Services' use of the premises. Consequently, Healthscope was restrained from proceeding with the alterations and a constructive trust was imposed over the contractual obligation.

The court ordered Healthscope to refrain from making the proposed alterations to the hospital premises and to compensate Specialist Diagnostic Services for any losses incurred as a result of the proposed alterations. The court also directed that a constructive trust be imposed over the contractual obligation, ensuring that Healthscope's actions did not infringe upon the legitimate business interests of Specialist Diagnostic Services.
