Placer (Granny Smith) Pty Ltd v Thiess Contractors Pty Ltd P47/2000

Placer (Granny Smith) Pty Ltd (Placer) and Thiess Contractors Pty Ltd (Thiess) were parties to a contract for the construction of a mine. A dispute arose concerning the interpretation of a clause in the contract relating to the payment of a bonus. Placer commenced proceedings in the Supreme Court of New South Wales seeking a declaration as to the proper interpretation of the clause. The Supreme Court found in favour of Thiess. Placer appealed to the High Court of Australia.

The High Court was required to determine the proper construction of clause 14.1 of the contract, which stipulated the conditions under which a bonus payment was to be made to Thiess. Specifically, the court had to consider whether the bonus was payable if the mine achieved a certain production level, even if that level was not sustained for the entire contract period, or if the level had to be maintained throughout the contract.

The High Court, in a joint judgment, held that the plain and ordinary meaning of the words in clause 14.1 indicated that the bonus was payable if the specified production level was achieved, irrespective of whether that level was sustained for the entire duration of the contract. The court emphasised the importance of construing contractual terms according to their ordinary meaning, unless the context clearly indicated a different intention. The court found no contextual indication that the production level needed to be sustained.

The appeal was allowed, and the orders of the Supreme Court of New South Wales were set aside. The High Court declared that Thiess was entitled to the bonus payment under clause 14.1 of the contract.
