Australian Provincial Assurance Association Ltd v Roddy

The High Court of Australia heard an appeal from the Supreme Court of New South Wales concerning the interpretation of Section 15(1) of the Landlord and Tenant (Amendment) Act 1948-1952 (NSW). The dispute arose when Australian Provincial Assurance Association Ltd. was convicted of receiving rent exceeding the fair rent for certain premises. The core of the issue was how to determine the "rent payable" on 1 March 1949, particularly when the original lease stipulated rent as a percentage of the lessee's gross receipts, a variable amount, rather than a fixed monetary sum.

The legal questions before the court were whether a rent calculated as a percentage of gross receipts constituted a "rent payable" for the purposes of Section 15(1), and if so, how such a rent should be quantified and compared to a later, fixed rent. Specifically, the court had to determine if the phrase "rent payable... at 1st March 1949" referred to a fixed monetary amount or a formula that yielded a variable amount, and whether the comparison required by the section was possible between these two types of rent.

The High Court affirmed the decision of the Supreme Court, holding that the phrase "the rent payable on 1st March 1949" connoted a sum expressed as a fixed monetary figure, not a sum expressed solely as a variable formula. The court reasoned that Section 15(1) was designed to establish a fixed standard of rent that could not be exceeded in subsequent periods. While acknowledging that rent could be calculated by a formula, the court found that for the purpose of comparison under Section 15(1), the rent payable on the specified date must be ascertainable as a definite sum. The court concluded that the rent payable on 1st March 1949, derived from the percentage of gross receipts for the relevant week, was £109 13s. 1d., and this sum served as the benchmark against which the later, fixed rent was to be compared. The appeal was dismissed.
