Dura (Australia) Constructions Pty Ltd v Hue Boutique Living Pty Ltd

The case between Dura (Australia) Constructions Pty Ltd and Hue Boutique Living Pty Ltd involved a dispute regarding the interpretation of a building contract. The appellant, Dura, was engaged by the respondent, Hue, to construct a building. The contract included a clause allowing the proprietor to take over the works and complete them, with the Supervisor determining the cost to complete and certifying the amount payable. The central issue was whether the Supervisor's certificate complied with the contract, whether the builder could challenge the certificate, and if the contractual dispute resolution procedures were mandatory. The case also considered the presumption of consistent meaning when interpreting contractual terms.

The court had to interpret the contractual language, particularly the term 'ascertain', and whether it allowed for any discretion by the Supervisor. The court noted that if the word 'ascertain' was used consistently throughout the contract, it should be interpreted in the same way each time. The court found that the Supervisor's role was to determine the cost based on the information available at the time, and this interpretation was consistent with the contract's language. The court also considered whether the builder's right to challenge the certificate was limited by any election or waiver, and found that the builder had not waived its right to challenge the certificate. The court concluded that the contractual dispute resolution procedures were not mandatory and that the builder could challenge the certificate without following these procedures.

The court dismissed the appeal, upholding the decision that the Supervisor's certificate was valid and that the builder had not complied with the contractual dispute resolution procedures. The court's interpretation of the contract terms, particularly the word 'ascertain', was pivotal in reaching this decision. The court's reasoning highlighted the importance of consistent interpretation of contractual language and the builder's right to challenge a certificate without being bound by dispute resolution procedures. The final orders of the court upheld the decision of the lower court, affirming that the Supervisor's certificate was valid and that the builder's challenge was not precluded by any election or waiver.
