Understanding Pre-existing Injury Aggravation in NSW CTP Claims
If you sustained a motor accident in Greater Sydney and your pre-existing injury was worsened by the crash, you may be entitled to compensation under the NSW Compulsory Third Party (CTP) insurance scheme. The Motor Accident Injuries Act 2017 (MAIA) governs these claims. Importantly, the law recognises that a motor accident can aggravate a pre-existing medical condition, and you may still be eligible for benefits even if the injury was not caused entirely by the accident. However, time limits apply, and they depend on the nature of the injury, the date of the accident, and whether you have previously made a claim.
Legal Framework for Aggravated Pre-existing Injuries
Under the MAIA, a person who suffers an injury as a result of a motor accident may be entitled to treatment and care benefits, weekly income payments, and, in some cases, damages. When a pre-existing injury is aggravated, the law treats the new harm as part of the injury caused by the accident. This means the CTP insurer must assess the extent of the aggravation and provide benefits accordingly. The insurer is not required to prove that the pre-existing condition was not present before the accident, but must determine the portion of the injury that resulted from the accident.
SIRA, the State Insurance Regulatory Authority, provides guidance on how to assess aggravation. The key principle is that the CTP insurer must consider the medical evidence to determine whether the accident caused or contributed to a worsening of the pre-existing condition. This assessment is made under the Motor Accident Injuries Regulation 2017 and the Motor Accident Guidelines.
Time Limits for Making a Claim
The primary time limit for making a claim under the CTP scheme is three years from the date of the motor accident. This is set out in the Motor Accident Injuries Act 2017. The three-year period applies regardless of whether the injury was new or aggravated. For example, if you were involved in a crash in Greater Sydney on 15 March 2024, you must make your claim by 15 March 2027.
However, if your injury was aggravated and you were not aware of the full extent of the harm at the time of the accident, the time limit may be extended under the principle of 'discovery'. This means the three-year period starts from when you first knew, or ought to have known, that the accident caused or contributed to a worsening of your condition. This is particularly relevant in cases where symptoms only became apparent months after the crash, or where a medical assessment later confirmed aggravation.
Evidence That Matters in Aggravation Claims
To support a claim for aggravated pre-existing injury, you must provide evidence that shows the accident caused or contributed to a worsening of your condition. Key evidence includes:
- Medical records from before and after the accident, showing the progression of the pre-existing injury.
- A medical report from a qualified practitioner, preferably a specialist, confirming that the accident caused or contributed to the aggravation.
- A record of any changes in symptoms, treatment, or functional capacity following the accident.
- Details of any treatment or rehabilitation received since the accident.
- Photographs of the accident scene, if available, and any witness statements.
SIRA notes that a claim for aggravated injury will not succeed if the medical evidence does not show a causal link between the accident and the worsening of the condition. The burden of proof lies with the claimant to demonstrate that the accident caused or contributed to the aggravation.
Practical Steps to Take
If you believe your pre-existing injury was aggravated by a motor accident in Greater Sydney, you should:
- Seek medical attention as soon as possible after the accident, even if symptoms were mild initially.
- Keep a detailed record of your symptoms, treatments, and any changes in your health.
- Notify your CTP insurer of the claim within the three-year time limit.
- Request a copy of your medical records and ensure they are properly documented.
- Do not delay seeking legal advice if the insurer disputes the claim or refuses to pay benefits.
Disputes and When to Seek Advice
If your CTP insurer refuses to accept that your pre-existing injury was aggravated, you may dispute the decision. You can request a review under the MAIA, or apply to the Civil and Administrative Tribunal (NCAT) for a determination. Disputes often arise when the insurer argues that the injury was not caused by the accident, or that the aggravation was not significant.
A common issue in Greater Sydney is that some claimants delay seeking medical treatment, which can weaken their case. The longer you wait to report symptoms, the harder it becomes to establish a direct link between the accident and the aggravation. Therefore, it is essential to act promptly.
Hypothetical Example
Consider a driver in Sydney who had a pre-existing back condition treated with physiotherapy. After a minor collision in a car park in February 2024, they began experiencing increased pain and reduced mobility. A specialist assessment in August 2024 confirmed that the accident had aggravated the pre-existing injury. The claim was made in October 2024, within the three-year limit. The CTP insurer accepted the claim based on medical evidence showing a causal link. The claimant received treatment and care benefits and was later awarded damages for the aggravated injury.
Next Steps
Every claim depends on its own facts. The time limits, medical evidence, and insurer response will determine whether a claim for aggravated pre-existing injury can proceed. The date of the accident, the nature of the injury, and the timing of medical assessments are critical factors.
