Dispute Resolution Options for CTP Claims Involving Vehicle Modifications 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've been injured in a motor vehicle accident and require vehicle modifications such as hand controls or mobility aids, you may have questions about how to resolve disputes over your CTP claim. In New South Wales, the dispute resolution process for CTP claims involving vehicle modifications is governed by the Motor Accident Injuries Act 2017 and the decisions of the State Insurance Regulatory Authority (SIRA). This article explains your options for resolving such disputes.

The NSW CTP Rules Behind Vehicle Modifications Claims

In NSW, CTP claims are governed by the Motor Accident Injuries Act 2017. This law ensures that injured parties receive compensation for injuries resulting from motor vehicle accidents, including the cost of vehicle modifications. SIRA plays a key role in determining the level of compensation and the type of modifications that are eligible.

When a claim involves vehicle modifications, the focus is on whether the modification is necessary due to a disability caused by the accident. SIRA assesses whether the modification meets the criteria outlined in the Motor Accident Guidelines. These guidelines define what constitutes a 'threshold injury' and what modifications are considered reasonable and necessary.

Practical Steps and Evidence That Usually Matter

To resolve a dispute over vehicle modifications, you must provide evidence that the modification is both necessary and reasonable. This includes:

  • Medical reports confirming your injury and the need for the modification.
  • Evidence of the modification's cost and the type of modification.
  • Documentation showing the modification was made after the accident.
  • Any correspondence with your insurer or SIRA.

It is important to ensure that your evidence clearly links the modification to your injury and demonstrates that it was necessary for your recovery.

Time Limits, Disputes and When to Seek Advice

Disputes over vehicle modifications can arise if your insurer or SIRA does not agree with the type or cost of the modification. In such cases, you have the right to challenge the decision. However, time limits apply. You must submit your claim within a reasonable time after the accident, and any dispute must be resolved within the timeframes set by SIRA.

If your claim is denied or you are unsatisfied with the outcome, you may need to seek legal advice. A solicitor can help you challenge the decision and ensure your rights are protected.

How SIRA Handles Disputes Related to CTP Claims Involving Vehicle Modifications

SIRA has a structured process for handling disputes. If your claim is denied, you can request a review. During the review, SIRA will consider your evidence and may request additional information. If the review does not resolve the dispute, you may have the option to escalate the matter to the Personal Injury Commission.

SIRA has the final authority on whether a modification is reasonable and necessary. Therefore, it is crucial to ensure your evidence is strong and well-supported.

A Hypothetical Example

Imagine you were involved in a car accident and suffered a spinal injury. As a result, you needed hand controls installed on your car. You submitted a claim to your insurer, but they denied the request, stating the modification was not necessary. You then contacted SIRA and provided your medical reports, which confirmed your injury and the need for the modification. After a review, SIRA approved your claim.

This example illustrates the importance of providing clear evidence and following the correct process when disputing a CTP claim involving vehicle modifications.

When to Seek Legal Advice

Disputes over vehicle modifications can be complex, and the outcome often depends on the strength of your evidence and your understanding of the legal process. If you are unsure about your options or your claim has been denied, it is advisable to seek legal advice. A solicitor can help you challenge the decision and ensure your rights are protected.

Next Steps

Disputes over CTP claims involving vehicle modifications can be resolved through SIRA and the Personal Injury Commission. However, the outcome depends on the strength of your evidence and your understanding of the legal process. If you are unsure about your options or your claim has been denied, it is advisable to seek legal advice.
