Insurer Denial of Your CTP Claim: Understanding Your Rights 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 your CTP insurer in NSW has denied your claim for motor accident compensation, you are not without recourse. Under the Motor Accident Injuries Act 2017, you have formal dispute resolution options available through the State Insurance Regulatory Authority (SIRA). These options are designed to resolve disagreements about liability, injury assessment, or the amount of benefits payable. The process is accessible to individuals across Greater Sydney and throughout NSW, and it does not require you to immediately engage a solicitor.

The Legal Framework for Dispute Resolution

The Motor Accident Injuries Act 2017 establishes the framework for resolving disputes between claimants and CTP insurers. If an insurer denies liability or refuses to pay benefits, you may request a review through SIRA’s dispute resolution process. This process includes internal review, mediation, and, where necessary, arbitration. These steps are mandatory before you can apply to the Personal Injury Commission for a determination on a claim.

SIRA is the independent body responsible for overseeing CTP claims in NSW. It provides guidance and facilitates dispute resolution, particularly where there is disagreement about the nature or extent of injuries, the need for treatment, or whether the accident caused the injury. The process is structured to ensure fairness and to encourage resolution without litigation.

Practical Steps to Challenge a Denial

To challenge a CTP claim denial, you must act promptly and gather evidence that supports your claim. The following steps are essential:

  • Notify the insurer in writing of your disagreement with the decision, clearly stating the grounds for your objection.
  • Request a formal internal review from the insurer. This must be done within 28 days of receiving the denial notice, unless the insurer has provided a different timeframe.
  • Gather and preserve all relevant evidence, including:
  • Medical records and reports from your treating practitioner
  • Accident scene photographs and witness statements
  • Police reports, if available
  • Records of lost income or out-of-pocket expenses
  • Correspondence with the insurer

SIRA’s guidelines confirm that medical evidence is critical in disputes involving injury assessment. A medical practitioner’s report that details the nature of your injury, its connection to the accident, and the recommended treatment is often the most persuasive evidence.

Mediation and Arbitration: Formal Dispute Pathways

If the insurer’s internal review does not resolve the dispute, you may proceed to mediation. SIRA offers free mediation services to help parties reach an agreement without going to court. Mediation is voluntary and typically involves a neutral third party who facilitates discussion. It is often successful in resolving issues about liability, treatment, or benefit entitlements.

If mediation fails, you may apply for arbitration. This is a binding process where a qualified arbitrator reviews the evidence and makes a final decision. You must have exhausted the internal review process and attempted mediation before applying for arbitration. The arbitrator’s decision is legally enforceable and may cover issues such as the value of weekly payments, treatment and care benefits, or the need for future care.

When to Seek Legal Advice

While you are not required to have a solicitor to use SIRA’s dispute resolution process, seeking independent legal advice is strongly recommended, particularly if:

  • The insurer disputes liability and you believe the accident was not your fault
  • You have a threshold injury and are concerned about the 52-week limit on benefits
  • The insurer challenges the medical evidence or the connection between your injury and the accident
  • You are seeking damages for pain and suffering, and the insurer claims you do not meet the threshold for a common law claim

A solicitor can help you assess whether your claim has merit, prepare a strong submission, and represent you in mediation or arbitration. They can also advise on whether a claim for damages may be viable, particularly if you have a permanent impairment or a non-threshold injury.

Hypothetical Example: A Claim Dispute in Sydney

Consider a scenario where a cyclist in North Sydney was struck by a car at a traffic light. The insurer denied the claim on the grounds that the cyclist was not wearing a helmet and therefore contributed to the injury. The cyclist provided a medical report confirming a concussion and ongoing headaches, supported by a police report and two witness statements.

The cyclist requested an internal review, which was denied. They then applied for mediation through SIRA. During mediation, the insurer accepted that the accident occurred and that the injury was sustained, but disputed the severity. The mediator helped both parties agree on a medical assessment by an independent specialist. The specialist’s report confirmed the concussion and recommended a treatment plan. As a result, the insurer agreed to pay for treatment and weekly income payments.

This example illustrates how the dispute resolution process can lead to a resolution even when the insurer initially denies liability or the extent of injury.

Time Limits and Procedural Requirements

Time is a critical factor in CTP claims. You must request an internal review within 28 days of receiving a denial. Failure to do so may prevent you from using SIRA’s dispute resolution pathways. There is no fixed deadline for applying to the Personal Injury Commission, but delays may affect the strength of your evidence and your ability to obtain timely benefits.

The outcome depends on the strength of your evidence and the legal interpretation of the Motor Accident Injuries Act 2017. However, the process provides a structured and fair way to challenge a denial and seek the compensation you believe you are entitled to.
