Western Districts Developments Pty Ltd v Baulkham Hills Shire Council

Western Districts Developments Pty Ltd (the applicant) appealed to the NSW Court of Appeal against decisions of the Local Court and the Supreme Court of NSW. The dispute concerned economic loss suffered by purchasers of lots from a subdivider, who were subsequently required by a water supply authority to comply with certain requirements after the subdivision certificate had been issued. The applicant argued that the respondent, Baulkham Hills Shire Council, as the principal certifying authority for the subdivision, owed a duty of care to these purchasers.

The central legal issue before the Court of Appeal was whether the respondent, in its capacity as the principal certifying authority, owed a duty of care to the purchasers of subdivided lots in relation to the issue of a subdivision certificate. This question arose in the context of the respondent allegedly misexercising its statutory power by issuing the certificate despite non-compliance with a requirement from the water supply authority, leading to the purchasers incurring economic loss. The Court also considered whether the lower courts' decisions, which found no such duty of care, were erroneous in point of law, thereby conferring jurisdiction on the appellate court.

The Court of Appeal found that the decisions of the lower courts were indeed erroneous in point of law. Applying principles of negligence and the misexercise of statutory power, the Court determined that a duty of care was owed by the principal certifying authority to the purchasers of the subdivided lots. The Court reasoned that the statutory framework imposed obligations on the certifying authority that extended to protecting the interests of those who would rely on the proper issuance of such certificates.

Consequently, the Court of Appeal granted leave to appeal, upheld the appeal, and set aside the previous decisions and orders. The matter was remitted to the Local Court for the assessment of the quantum of damages, and the respondent was ordered to pay the applicant's costs.
