Australian Postal Corporation (T/as Australia Post) v A J Dowse

The Australian Postal Corporation, trading as Australia Post, appealed to the New South Wales Court of Appeal against a decision of the Supreme Court of New South Wales. The dispute concerned the interpretation of a clause within a lease agreement between Australia Post and the respondents, A J Dowse and another party, relating to the calculation of a rent review.

The primary legal issue before the Court of Appeal was whether the rent review clause, which stipulated that rent should be reviewed to "market rent" at the end of a five-year term, required the landlord to provide evidence of comparable market rents to justify the proposed increase. Specifically, the court had to determine if the landlord bore the onus of proving that the proposed rent was indeed the market rent, or if the tenant was required to demonstrate that it was not.

The Court of Appeal held that the lease agreement did not impose an express obligation on the landlord to provide evidence of comparable market rents. It reasoned that the clause simply required the rent to be reviewed to market rent, and it was for the parties to negotiate this figure. If agreement could not be reached, the dispute resolution mechanism within the lease would be invoked. The court applied the principle of contractual interpretation that terms are to be given their ordinary and natural meaning, and that an obligation to provide evidence of market rent would need to be clearly stipulated.

The appeal was allowed, and the Supreme Court's decision was set aside. The Court of Appeal remitted the matter back to the Supreme Court for further determination in accordance with its judgment.
