Pre-existing Injury Aggravation in NSW CTP Claims

If you have a pre-existing injury that worsens after a motor accident in New South Wales, you may be eligible for compensation under the Compulsory Third Party (CTP) scheme. However, disputes often arise over whether the aggravation is a direct result of the accident. Understanding the legal framework and dispute resolution options is critical to protecting your claim.

Legal Framework for Pre-existing Injury Aggravation

  • Under the Motor Accident Injuries Act 2017 (MAIA), a pre-existing injury is considered 'aggravated' if the accident causes a
  • material worsening* of the condition. This includes increased pain, reduced mobility, or a need for additional treatment. The key legal test is whether the accident caused a
  • significant change in the injury's severity* compared to its state before the crash.

SIRA (State Insurance Regulatory Authority) clarifies that aggravation claims must demonstrate a direct link between the accident and the worsened condition. Medical evidence is essential to establish this connection. For example, a pre-existing back injury that required a new MRI after the accident could support a claim for aggravation.

Dispute Resolution Options

1. Internal Review by the CTP Insurer

If your claim is denied or disputed, the first step is to request an internal review with the CTP insurer. You must submit a written objection within 28 days of the decision. The insurer will reassess the claim based on updated evidence, such as medical reports or expert opinions.

2. Personal Injury Commission (PIC) Review

If the insurer's decision remains unchanged, you can apply for a review by the Personal Injury Commission (PIC). This body evaluates disputes over the nature and extent of injuries and may request additional medical assessments. The PIC's decision is binding unless appealed.

3. Legal Action

In complex cases, legal action may be necessary. A solicitor can help challenge the insurer's interpretation of the aggravation. However, legal proceedings are costly and time-consuming, so they are typically a last resort. The court will assess whether the aggravation meets the legal threshold under the MAIA.

Practical Steps for Claimants

To strengthen your case, take the following steps:

  • Document the pre-existing injury: Provide medical records, diagnosis dates, and treatment history before the accident.
  • Seek immediate medical attention: Document how the accident worsened your condition. For example, a new MRI or X-ray showing increased damage.
  • Preserve accident evidence: Keep records of the crash, witness statements, and any police reports.
  • Notify the insurer: Inform the CTP insurer of the aggravation within the required time limits (usually 28 days from the accident date).

Time Limits and When to Seek Advice

CTP claims must be submitted within two years of the accident date. However, disputes over aggravation may extend this deadline if the injury's worsening is discovered later. For example, a delayed diagnosis of a spinal injury could justify a longer claim period.

If you face a dispute, seek legal advice promptly. Delays can jeopardize your ability to prove the aggravation, especially if medical evidence is time-sensitive. A solicitor can also help challenge the insurer's interpretation of the MAIA.

Hypothetical Example

Consider a scenario where a person with a pre-existing knee injury (diagnosed in 2023) experiences increased pain and swelling after a 2025 car accident. The insurer denies the claim, arguing the worsening is unrelated. The claimant submits a new MRI showing cartilage damage caused by the accident. After an internal review and PIC assessment, the claim is approved as the aggravation meets the legal threshold.

Next Steps

Disputes over pre-existing injury aggravation require careful navigation of the CTP scheme. While the MAIA provides a pathway for compensation, the process involves proving a direct link between the accident and the worsened condition. If you are facing a dispute, seek legal advice to ensure your claim is assessed fairly.
