How NSW CTP Insurers Assess Liability Under the Motor Accident Injuries Act 2017

A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).

Under the Motor Accident Injuries Act 2017, NSW insurers assess liability for CTP claims by determining fault in a motor accident. This process involves evaluating whether the accident was caused by a negligent or unlawful act, and whether the injured person meets the legal criteria for compensation. Fault is a central factor, but insurers also consider contributory fault, the nature of injuries, and whether the claimant is eligible for statutory benefits.

Key Factors in Liability Assessments

NSW insurers evaluate several factors when determining liability under the 2017 Act. These include:

  • Fault: Whether the accident was caused by a breach of duty of care by a driver, pedestrian, or other party.
  • Contributory fault: If the claimant contributed to the accident, this may reduce the compensation amount.
  • Threshold injury: Injuries must meet the definition of a 'threshold injury' under the Motor Accident Guidelines to qualify for statutory benefits.
  • Spinal nerve-root injury: A spinal nerve-root injury producing neurological signs may still count as a soft-tissue injury, even if it does not meet the radiculopathy criteria.
  • Evidence: Medical records, accident reports, witness statements, and police reports are critical to support the claim.

Insurers also apply the 52-week statutory benefit rule. If a claimant's only injuries are threshold injuries, weekly benefits and treatment benefits are generally limited after 52 weeks. This does not apply to claims involving whole-person impairment or long-term care needs.

Role of SIRA Guidelines

The State Insurance Regulatory Authority (SIRA) provides authoritative guidance on assessing liability and determining compensation under the 2017 Act. SIRA's guidelines clarify how insurers evaluate injuries, including:

  • Defining 'threshold injuries' based on clinical signs and symptoms.
  • Calculating weekly benefits for treatment and care.
  • Determining whether a claimant is eligible for lifetime care or additional compensation.

SIRA also outlines how insurers must handle disputes, including the right of claimants to request a review of a decision. This ensures consistency in how liability is assessed across NSW.

Practical Steps for Claimants

If you've been injured in a motor accident in Bathurst, take these steps to support your claim:

  • Seek immediate medical attention to document injuries and establish a medical record.
  • Preserve evidence such as accident reports, photographs, and witness details.
  • Notify your insurer as soon as possible to avoid missing time limits.
  • Keep records of income and expenses to support claims for weekly benefits.

Insurers typically have 28 days to respond to a claim under the 2017 Act. If they deny your claim, you may request a review or seek independent legal advice.

When to Seek Legal Advice

While insurers must follow the 2017 Act and SIRA guidelines, disputes can arise over the interpretation of fault, injury severity, or eligibility for benefits. Legal advice is essential if:

  • You believe the insurer has misapplied the guidelines.
  • You have suffered a whole-person impairment or long-term injury.
  • You are unsure whether your injuries meet the threshold injury definition.

Legal professionals can help you understand your rights under the Act and ensure your claim is assessed fairly.
