How to Resolve Disputes Over CTP Claims in NSW

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).

If you're involved in a Compulsory Third Party (CTP) claim under the Motor Accidents Compensation Act 1999 (MA 1999), disputes over compensation or benefits are resolved through specific legal and administrative processes. This article explains the options available to claimants and insurers, including SIRA's role, mediation, and legal boundaries.

Understanding the Dispute Process

Disputes over CTP claims in NSW are governed by the MA 1999 and the Motor Accident Injuries Act 2017 (MAIA). While the MA 1999 applies to claims before 1 December 2017, disputes under this scheme are resolved through a structured pathway. Key steps include:

  • Mediation: SIRA offers mediation to resolve disputes without court involvement. This process allows claimants and insurers to discuss issues like injury assessments, benefit calculations, or treatment coverage.
  • Internal Review: If mediation fails, claimants can request an internal review of SIRA’s decision within 28 days. This review considers new evidence or reassesses the claim based on updated information.
  • Legal Action: If disputes persist, claimants may pursue legal remedies, such as filing a claim in the NSW Civil and Administrative Tribunal (NCAT) or the District Court. However, legal action is typically a last resort and requires meeting strict procedural requirements.

SIRA's Role in Dispute Resolution

SIRA (State Insurance Regulatory Authority) administers CTP claims under the MA 1999. When disputes arise, SIRA follows these steps:

  1. Initial Assessment: SIRA evaluates claims based on medical evidence, accident reports, and policy terms. Claimants receive a written decision outlining the benefits awarded.
  2. Dispute Notice: If a claimant disagrees with the decision, they must notify SIRA in writing within 28 days. This triggers an internal review.
  3. Internal Review Process: SIRA reviews the claim, considering new evidence or clarifications. The review must be completed within 28 days of the dispute notice.
  4. Final Decision: If the review does not resolve the dispute, SIRA may issue a final decision. Claimants can then seek legal advice to challenge the decision.

Legal Boundaries and Practical Considerations

Disputes under the MA 1999 are subject to specific legal limits. For example:

  • Threshold Injuries: Claims for soft-tissue injuries (threshold injuries) are limited to 52 weeks of weekly benefits under the MA 1999. After this period, claimants may need to pursue other avenues, such as common law damages.
  • Time Limits: Most disputes must be resolved within 28 days of the initial decision. Missing these deadlines may prevent claimants from challenging SIRA’s decision.
  • Evidence Requirements: SIRA requires medical records, accident reports, and other evidence to support claims. Disputes often arise when evidence is incomplete or contested.

A Hypothetical Example

Imagine a claimant who sustained a soft-tissue injury in a car accident. SIRA initially awards 52 weeks of weekly benefits. The claimant disputes this, arguing the injury meets the threshold injury definition. SIRA conducts an internal review but upholds the decision. The claimant then seeks legal advice, exploring options like NCAT review or common law damages.

When to Seek Legal Advice

Disputes over CTP claims can be complex. Claimants should consider legal assistance if:

  • SIRA’s decision is final and not appealed.
  • The claim involves long-term injuries or disputes over impairment assessments.
  • There are overlaps with other schemes, such as workers’ compensation.

Legal professionals can help navigate procedural requirements, challenge SIRA decisions, and explore alternative remedies.

Next Steps

Disputes over CTP claims under the MA 1999 require careful navigation of administrative and legal processes. While SIRA provides mediation and internal review options, claimants must act within strict time limits. Every claim depends on its own facts.
