Lange v Queensland Building Services Authority

Lange v Queensland Building Services Authority involves a dispute between Lange, a builder, and the Queensland Building Services Authority (QBSA). The QBSA, as the statutory body overseeing building services, provided insurance coverage to the homeowners under the Queensland Building Industry Services Authority Act 1991 (Qld). The homeowners terminated a contract with Lange due to incomplete work and claimed $200,000 from the QBSA under the insurance policy. The QBSA subsequently sought indemnity from Lange under the same Act, arguing that an exclusion clause in the insurance policy applied. The central legal issue before the court was whether this exclusion clause barred the QBSA from making a claim against Lange. This required the court to interpret the meaning of "residential construction work" within the policy and the Act and to determine whether certain legislative provisions and amendments could inform this interpretation.

The court held that the exclusion clause in question did not apply to the facts of this case. It found that the clause was intended to cover specific types of buildings and not to create nonsensical results that would allow the QBSA to escape liability. The court noted that the policy was a statutory instrument, and thus, its interpretation should best achieve the purpose of consumer protection as set out in the Act. Furthermore, the court found that "residential construction work" had the same meaning in the Act, the QBSA Regulation, and the policy. The court also observed that the purpose of the Act was consumer protection, and the policy should be construed to best achieve this purpose. The court rejected Lange’s argument that a later legislative amendment could inform the interpretation of the policy, holding that such amendments could not be used to retrospectively alter the meaning of the policy.

The appeal was dismissed with costs, and Lange was ordered to pay the QBSA’s costs. The court concluded that the QBSA was correct in its interpretation that the exclusion clause did not apply and that the homeowners were entitled to payment. The court further held that the purpose of the legislation and the policy was to protect consumers, and the interpretation that best achieved this purpose should be preferred. The court also noted that if the legislature had intended for the exclusion clause to apply in circumstances such as these, it would have been relatively simple to incorporate this into the clause.
