The recent Queensland Supreme Court decision in Dennison v Brisbane City Council [2026] QSC 83 is a significant authority on the liability of public authorities in negligence, particularly the operation of s 36 of the Civil Liability Act 2003 (Qld) (CLA). The case clarifies that this provision provides a broad and powerful defence to councils, even where ordinary negligence principles would otherwise establish liability.
Until recently, plaintiffs pursuing negligence claims against councils have relied on the decade-old authority of Hamcor Pty Ltd v State of Queensland [2014] QSC 224. In that case, Dalton J held that s 36 of the Civil Liability Act 2003 (Qld) was confined to claims for breach of statutory duty, drawing heavily on the section’s heading, which refers to proceedings “based on breach of statutory duty.”
However, Dennison v Brisbane City Council marks a decisive departure from that interpretation. Crowley J declined to follow Hamcor, instead adopting the broader approach developed by the New South Wales Court of Appeal in Seqwater v Rodriguez & Sons Pty Ltd (2021) 393 ALR 162. In Rodriguez, it was held that provisions equivalent to s 36 are not limited by their headings, and extend to negligence claims arising out of the exercise of statutory functions.
In reaching this conclusion, Crowley J undertook a detailed examination of the text, context, and legislative history of the Civil Liability Act, including the explanatory notes to the Civil Liability Bill 2002. His Honour ultimately found that s 36 was intended to operate more broadly, providing a general protective framework for public authorities performing statutory functions, rather than being confined to a narrow category of statutory duty claims.
The practical consequence of this interpretation is significant. Plaintiffs can no longer succeed merely by establishing negligence in the conventional sense. Instead, they must meet the far more demanding “Wednesbury unreasonableness” standard – demonstrating that the authority’s conduct was so unreasonable that no reasonable public authority in the same position could have regarded it as a proper exercise of its functions.
What does this mean for you?
This represents a recalibration of the liability landscape in Queensland. While it remains to be seen whether the decision will be tested on appeal, the immediate effect is clear: public authorities, particularly local councils and road authorities, are now equipped with a significantly strengthened defence. That said, the decision does not close the door on claims altogether. Where the evidence demonstrates a serious failure in risk management, or conduct falling well outside acceptable standards, plaintiffs can still succeed – and the clarified framework may in fact sharpen the focus of claims and strengthen well‑founded cases.
