Chengcheng (Aust) Enterprise Melbourne Pty Ltd v Mansfield Corporation Pty Ltd

Chengcheng (Aust) Enterprise Melbourne Pty Ltd (the appellant) appealed to the Court of Appeal of the Supreme Court of New South Wales against a decision of the primary judge concerning a design and construction contract with Mansfield Corporation Pty Ltd (the respondent). The dispute centred on the interpretation of a clause that entitled the contractor to reimbursement of loss or expense at a specified daily rate if the progress of the works was delayed or disrupted by "a Variation". The appellant argued that the primary judge erred in finding the clause applicable, contending that there was no actual delay to the works because an extension of time had been approved, or alternatively, that there was already an agreement as to the cost consequences of the variation.

The Court of Appeal was required to determine whether the primary judge had correctly interpreted the contract clause in question. Specifically, the court had to consider whether the clause’s entitlement to reimbursement for loss or expense due to a variation was contingent on proof of actual delay to the works, or whether the approval of an extension of time satisfied this requirement. Furthermore, the court had to assess whether a pre-existing agreement on the cost consequences of a variation precluded the application of this specific reimbursement clause.

The Court of Appeal found no error in the primary judge’s interpretation of the contract. The judges reasoned that the clause did not require proof of actual delay to the works, but rather that the delay or disruption was *caused* by a variation. The approval of an extension of time was considered evidence of such causation. The court also held that the existence of an agreement on the cost consequences of a variation did not necessarily exclude the operation of the loss or expense clause, particularly where the agreement did not encompass all the losses or expenses contemplated by that clause. Consequently, the appeal was dismissed.

In addition, the Court of Appeal refused the appellant leave to file an amended defence in the District Court proceedings and refused the respondent leave to cross-appeal, with both applications dismissed with costs.
