Landmark NSW Ruling: New Risks for Construction Liability Insurance

Court Decision Eliminates Proportionate Liability Defence for Builders and Developers

Landmark NSW Ruling: New Risks for Construction Liability Insurance?w=400

The information on this website is general in nature and does not take into account your objectives, financial situation, or needs. Consider seeking personal advice from a licensed adviser before acting on any information.

Recent developments in New South Wales have significantly altered the liability landscape for construction professionals.
A landmark court ruling in the Pafburn case has removed the proportionate liability defence previously relied upon by developers and head contractors, thereby increasing their exposure to claims related to building defects.

The Design and Building Practitioners Act 2020 (DBP Act) introduced a statutory duty of care aimed at protecting property buyers from construction defects. This duty is non-delegable, retrospective, and applies to all participants in the construction process, including individual employees and directors.

The Pafburn case clarified that breaches of this statutory duty create a vicarious-like liability, meaning that builders and developers are now fully responsible for the entire cost of rectifying defects, regardless of subcontractor involvement. This places the onus on them to pursue subcontractors through separate legal actions.

Given these changes, it is imperative for construction companies and professionals to reassess their professional indemnity (PI) insurance policies to ensure they provide adequate coverage for the increased risks. Additionally, strategic management of complex multi-party litigation, such as initiating cross-claims, will be essential in allocating remediation costs appropriately among responsible parties.

These developments underscore the need for heightened diligence and comprehensive risk management strategies within the construction industry to navigate the evolving legal landscape effectively.
