Dispute Resolution under the Motor Accident Injuries Act 2017 in NSW

If you have a motor accident in Greater Sydney and are dissatisfied with a decision made by your CTP insurer under the Motor Accident Injuries Act 2017 (MAIA), you have several formal dispute resolution options. These options are available whether the dispute concerns a denial of treatment and care benefits, a reduction or cessation of weekly income payments, a disagreement over the assessment of your impairment, or a refusal to pay damages. The process is governed by the MAIA and administered by the Motor Accident Commission (MAC) and the Personal Injury Commission (PIC), which is part of the State Insurance Regulatory Authority (SIRA). The dispute resolution pathway is the same across NSW, including Greater Sydney, and is designed to provide a structured and timely way to resolve disagreements without immediately resorting to court.

How Dispute Resolution Works for CTP Claims in NSW

The first step in resolving a dispute under the MAIA is to request an internal review from your CTP insurer. This must be done within 60 days of receiving the insurer’s decision. The insurer is required to review the decision and notify you of the outcome within 30 days. If the insurer upholds its original decision, you may then apply to the Personal Injury Commission (PIC) for a review. The PIC is an independent body that assesses disputes on the merits of the law and the evidence. You must apply to the PIC within 60 days of receiving the insurer’s internal review outcome. The PIC will consider all relevant evidence, including medical reports, treatment records, income documentation, and any correspondence with the insurer.

If you disagree with the PIC’s decision, you may apply to the NSW Civil and Administrative Tribunal (NCAT) for a review. This is the final step in the statutory dispute resolution pathway. An application to NCAT must be made within 30 days of receiving the PIC’s decision. NCAT has the authority to confirm, vary, or set aside the PIC’s decision. The outcome of a dispute depends on the strength of the evidence and the application of the MAIA and the Motor Accident Injuries Regulation 2017.

Key Considerations in CTP Dispute Resolution

Several factors influence the outcome of a dispute under the MAIA. First, the nature of the injury matters. If your injury is a threshold injury (such as a soft tissue injury), the insurer may apply the 52-week rule, which limits statutory benefits to 52 weeks from the date of the accident, unless the injury results in a permanent impairment. For injuries that exceed the threshold, the insurer must assess your whole person impairment (WPI) using the Motor Accident Guidelines. A medical assessment by a qualified independent medical practitioner is required for this process.

Second, the quality and timeliness of medical evidence are critical. The insurer must accept a medical report from your treating practitioner unless it is inconsistent with accepted medical standards. If the insurer disputes the medical evidence, you may request a second opinion or apply to the PIC to review the assessment. The PIC may also order a new medical assessment if it finds the evidence insufficient or contradictory.

Third, the timing of your claim and any prior claims may affect eligibility. If you have previously made a claim under the MAIA, the insurer may consider your claim history when assessing your current dispute. This includes whether you have previously received benefits, whether you were assessed as having a threshold injury, or whether you have been involved in a dispute over impairment.

Practical Steps and Evidence That Matter

To strengthen your position in a dispute, you should gather and preserve the following evidence:

  • A copy of the insurer’s decision letter, including the reasons for denial or reduction.
  • All medical records related to the accident, including GP notes, specialist reports, imaging results, and treatment plans.
  • Records of any treatment and care benefits received, including invoices and receipts.
  • Proof of income loss, such as payslips, tax returns, or a letter from your employer.
  • Photographs of the accident scene, vehicle damage, or any visible injuries.
  • Details of any witnesses, including contact information.
  • All correspondence with the insurer, including emails, letters, and call logs.

If your dispute involves a disagreement over impairment, you must ensure that the medical assessment was conducted by a qualified independent medical practitioner and that the assessment followed the Motor Accident Guidelines. The PIC will not accept a report that does not comply with the guidelines.

When to Seek Advice and the Role of Legal Representation

Disputes under the MAIA can be complex, particularly when they involve medical assessments, impairment calculations, or questions about fault. While you are not required to have a solicitor to make a claim or dispute a decision, legal advice can significantly improve your chances of a favourable outcome. A solicitor can help you understand your rights under the MAIA, prepare a strong application to the PIC, and represent you at NCAT if necessary.

The process is not guaranteed to result in a change of decision. The PIC and NCAT will make decisions based on the law and the evidence, not on the strength of your argument alone. However, a well-documented dispute with accurate medical and financial evidence is more likely to succeed.

Hypothetical Example

A pedestrian in Sydney’s inner west was struck by a car in a crosswalk in May 2024. The insurer initially approved treatment and care benefits but later refused to pay weekly income payments on the grounds that the injury was a threshold injury and that the 52-week limit had been reached. The injured person had ongoing pain and limited mobility, supported by medical reports from a physiotherapist and a specialist. After requesting an internal review, the insurer maintained its decision. The person then applied to the PIC, submitted updated medical evidence, and requested a review of the impairment assessment. The PIC agreed to a new medical assessment and, after reviewing the evidence, ordered the insurer to resume weekly payments and reassess the WPI. This example illustrates how a structured dispute process can lead to a change in outcome when supported by strong evidence.
