How SIRA Handles Contributory Negligence in NSW CTP Claims

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

If you were injured in a motor accident in NSW and are seeking compensation, contributory negligence could affect your claim. The New South Wales Motor Accident Injuries Act 2017 and the State Insurance Regulatory Authority (SIRA) determine how shared fault impacts compensation outcomes. This article explains how SIRA interprets contributory negligence in Western Sydney cases, focusing on practical steps, evidence requirements and legal boundaries.

What Is Contributory Negligence in CTP Claims?

Contributory negligence refers to situations where the injured person also contributed to the accident. Under NSW law, SIRA assesses whether the claimant’s actions or decisions played a role in causing or worsening the injury. For example, if a pedestrian jaywalked into the path of a vehicle, SIRA may reduce compensation based on the claimant’s degree of fault.

SIRA’s approach is outlined in its guidelines for motor accident claims. It considers factors such as the claimant’s awareness of risks, adherence to traffic rules, and whether they took reasonable steps to avoid harm. The key is whether the injured person’s actions were a ‘contributory cause’ of the injury, as defined by the Motor Accident Injuries Act 2017.

How SIRA Applies Contributory Negligence in Western Sydney

SIRA’s interpretation of contributory negligence in Western Sydney cases is consistent with its national framework but may reflect regional practices. For instance, SIRA considers local traffic patterns, road conditions and common accident scenarios when assessing fault. A 2023 SIRA case summary noted that claimants who failed to use pedestrian crossings in busy areas were often found to have contributed to their injuries.

In practice, SIRA evaluates contributory negligence by reviewing:

  • Medical records showing the injury’s nature and severity
  • Police reports or accident statements
  • Witness statements
  • Evidence of the claimant’s actions before, during and after the accident

Practical Steps for Claimants

To support your CTP claim, gather evidence that demonstrates:

  • The full circumstances of the accident, including traffic conditions and vehicle movements
  • Your actions and decisions at the time of the incident
  • Any injuries or damages sustained
  • Medical treatment records and expert opinions

SIRA may also request additional information if it suspects contributory negligence. For example, if a cyclist was riding against traffic, SIRA might investigate whether they followed local cycling laws.

Time Limits and Dispute Resolution

NSW CTP claims must be submitted within 52 weeks of the accident, unless an extension is granted. If contributory negligence is disputed, SIRA provides a formal review process. Claimants can request a review of the decision, and in some cases, escalate to the NSW Civil and Administrative Tribunal (NCAT) for further assessment.

When to Seek Legal Advice

Contributory negligence assessments can be complex, especially when multiple factors are involved. If you’re unsure how your actions might affect your claim, or if SIRA has reduced your compensation, it’s important to consult a legal professional. A solicitor can help you understand your rights and ensure all evidence is properly presented.
