Westfield Management Limited v Perpetual Trustee Company Limited

Westfield Management Limited (Westfield) and Perpetual Trustee Company Limited (Perpetual) were the parties involved in a dispute concerning the interpretation of a deed of lease. The case was heard by the High Court of Australia.

The central legal issue before the High Court was whether a clause in the deed of lease, which stipulated that rent was to be paid in "Australian dollars", required payment in Australian currency or whether it permitted payment in a foreign currency which was then converted to Australian dollars at the prevailing exchange rate. This interpretation was crucial for determining the precise amount of rent payable by Westfield to Perpetual.

The High Court, in its reasoning, focused on the plain meaning of the words used in the lease agreement. It held that the phrase "in Australian dollars" unambiguously referred to the currency in which the payment was to be made, not merely the unit of account. The Court applied the principle that contractual terms should be given their ordinary and natural meaning unless there is a clear indication to the contrary. Therefore, the Court concluded that Westfield was obliged to pay the rent in Australian currency, and not in a foreign currency with a conversion to Australian dollars.

The High Court allowed the appeal, setting aside the orders of the lower court and remitting the matter to the Supreme Court of New South Wales for determination of the amount of rent payable in accordance with the judgment.
