How SIRA Determines Permanent Impairment Thresholds for CTP Claims
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 New South Wales law, a claimant must demonstrate a permanent impairment of at least 10% whole person impairment (WPI) to access damages under the Motor Accident Injuries Act 2017. This threshold is enforced by the State Insurance Regulatory Authority (SIRA), which assesses claims using clinical guidelines and medical evidence. In Bega, as elsewhere in NSW, SIRA applies this standard to determine whether a claimant qualifies for compensation beyond statutory benefits.
The Legal Framework Behind the Threshold
The 10% WPI threshold is defined in Schedule 1 of the Motor Accident Injuries Act 2017. It is a statutory benchmark that separates claims for statutory benefits (such as weekly payments and treatment benefits) from claims for damages. SIRA's role is to evaluate whether a claimant's injuries meet or exceed this threshold using the Motor Accident Guidelines. For example, a spinal nerve-root injury with neurological signs may qualify as a threshold injury, while radiculopathy requires specific clinical signs under the guidelines.
Practical Steps and Evidence for Claimants
To support a claim for damages, injured claimants in Bega must provide:
- Medical reports from registered medical practitioners detailing the nature and permanence of the injury
- Evidence of how the injury affects daily activities or employment
- Documentation of treatment received and its outcomes
SIRA may request additional assessments from independent medical experts if the initial evidence is unclear. Claimants should ensure all records are comprehensive and directly link the injury to the accident.
Time Limits and Dispute Resolution
Claims must be made within 52 weeks of the accident if the injury is classified as a 'threshold injury' under the Act. If the injury exceeds the 10% threshold, there is no time limit for pursuing damages. Disputes over SIRA's assessment can be escalated to the NSW Civil and Administrative Tribunal (NCAT) for review. Claimants should seek legal advice promptly if they believe SIRA's evaluation is incorrect or incomplete.
When to Seek Independent Legal Advice
Claimants in Bega should consult a solicitor if:
- They are unsure whether their injury meets the 10% WPI threshold
- They disagree with SIRA's assessment of their impairment
- They need assistance navigating the claims process
Legal professionals can help interpret SIRA's guidelines, challenge incorrect assessments, and ensure claimants understand their rights under the Motor Accident Injuries Act 2017.
Final Considerations
The 10% WPI threshold is a critical legal boundary in NSW CTP claims. While SIRA provides authoritative guidance, claimants must ensure their evidence clearly demonstrates how their injury meets or exceeds this standard. Time limits and procedural requirements vary depending on the nature of the injury, making it essential to seek legal advice early.
