Specialist Diagnostic Services Pty Ltd v Healthscope Ltd

Specialist Diagnostic Services Pty Ltd (SDS) brought proceedings against Healthscope Ltd (Healthscope), alleging breaches of covenant, breaches of contract and seeking declarations in relation to the sale of its business to Healthscope. The case was heard in the Federal Court of Australia. The primary dispute involved the interpretation and enforceability of certain restraints of trade clauses in a lease agreement and the implications of these clauses on the sale of SDS's business to Healthscope. The court had to determine the validity of the restraint of trade provisions, whether they were enforceable, and whether Healthscope breached any implied obligations of good faith in the context of the sale.

The legal issues centred around the enforceability of the restraint of trade clauses in the lease and whether these clauses were reasonable and enforceable under Australian law. The court needed to consider whether the restraints were inherently limited geographically, whether they failed the "existing freedom" and "trading society" tests, and if the duration of the restraints was reasonable. Additionally, the court examined whether Healthscope breached any implied obligations of good faith or an implied covenant not to derogate from the grant, and whether the purchaser of SDS's business was bound by the lease's covenants and obligations.

The court found that the restraint of trade provisions were unreasonable as they did not have an inherent geographic limit and failed both the "existing freedom" and "trading society" tests. The duration of the restraints was also considered unreasonable. The court held that the restraints were not justified by any legitimate interest and were therefore unenforceable. Regarding the implied obligations of good faith, the court held that such obligations apply to leases and that Healthscope did not breach an implied obligation not to derogate from the grant as its conduct did not render SDS's business "uneconomic". The court further found that the purchaser of SDS's business was not bound by the lease's covenants and obligations unless the vendor intended to hold the benefit of those promises on trust for the tenant.

The court declared that the restraint of trade provisions in the lease were unenforceable and that Healthscope did not breach any implied obligations of good faith. The court also found that the purchaser of SDS's business was not bound by the lease's covenants and obligations.
