Christmas Island Resort Pty Ltd v Geraldton Building Co

The dispute in *Christmas Island Resort Pty Ltd v Geraldton Building Co* concerned a contract for the construction of a resort on Christmas Island. Christmas Island Resort Pty Ltd (the appellant) engaged Geraldton Building Co (the respondent) as the builder. A dispute arose regarding the interpretation of a clause in the contract that dealt with the calculation of the contract price, specifically concerning the inclusion of a sum for "escalation". The matter came before the High Court of Australia.

The central legal issue before the High Court was the proper construction of clause 10.1 of the building contract. This clause stipulated that the contract price was to be calculated by adding to a base sum an amount for "escalation". The appellant contended that this escalation amount was to be calculated by reference to a specific formula provided in an annexure to the contract, which would result in a lower figure. The respondent argued that the escalation was to be calculated by reference to a different, more favourable method, effectively meaning the escalation was to be added to the base sum without the application of the formula in the annexure.

The High Court, in a joint judgment delivered by Toohey, Gaudron and Gummow JJ, held that the contract was to be construed according to its plain language. Their Honours found that the annexure, which contained the formula, was intended to provide a method for calculating the escalation amount, and that the appellant's interpretation was consistent with the overall scheme of the contract. The court emphasised the importance of giving effect to the clear and unambiguous terms of a written contract, even if one party might have intended a different outcome. The appeal was allowed.
