Gumland Property Holdings Pty Limited v Duffy Bros Fruit Market (Campbelltown) Pty Limited & Ors

The High Court of Australia considered a dispute between Gumland Property Holdings Pty Limited (the appellant) and Duffy Bros Fruit Market (Campbelltown) Pty Limited and others (the respondents) concerning a retail lease. The core of the disagreement revolved around the interpretation of a rent review clause within the lease agreement.

The central legal issue before the High Court was whether the rent review clause, which stipulated that rent should be reviewed to "market rent" at the end of each five-year term, required the landlord to provide evidence of the market rent at the time of the review, or if the tenant bore the onus of proving the rent was not the market rent.

The High Court held that the onus rested on the landlord to establish that the proposed rent represented the market rent. The Court reasoned that the landlord, seeking to increase the rent, bore the burden of proving that the conditions for such an increase under the lease had been met. This involved demonstrating, with evidence, what the market rent was at the relevant review date. The Court emphasised that a rent review clause is a mechanism for adjusting rent to reflect current market conditions, and the party seeking to invoke that adjustment must provide the necessary substantiation.

The appeal was dismissed, with the High Court affirming the decision of the New South Wales Court of Appeal.
