How to Challenge an NSW CTP Insurer Decision

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're in Ashfield and your insurer has denied or limited your motor accident compensation claim, you may be able to challenge their decision through the State Insurance Regulatory Authority (SIRA). This guide explains how to dispute an insurer's decision under NSW's Compulsory Third Party (CTP) scheme, including what evidence to gather and when to seek help.

Understanding the Legal Framework

NSW's Motor Accident Injuries Act 2017 governs CTP claims. Under this law, insurers must assess claims based on medical evidence and the Motor Accident Guidelines. If an insurer denies a claim or limits benefits, claimants can challenge the decision by lodging a complaint with SIRA.

SIRA oversees the CTP scheme and resolves disputes between claimants and insurers. This includes reviewing whether an insurer applied the correct legal standards, such as whether a threshold injury was properly assessed or if a claimant is eligible for weekly payments.

Practical Steps to Challenge an Insurer Decision

To challenge an insurer's decision, follow these steps:

  • Gather evidence: Collect all documents related to your claim, including medical records, accident reports, witness statements, and correspondence with the insurer.
  • Review the insurer's decision: Carefully read the insurer's letter explaining their decision. Note any specific reasons given, such as a claim being denied due to a 'threshold injury' or a dispute over treatment costs.
  • Lodge a complaint with SIRA: Complete SIRA's complaint form and submit it within 28 days of the insurer's decision. You can find the form on SIRA's website or request it by phone.
  • Include supporting documents: Attach copies of all relevant evidence to your complaint. This helps SIRA understand your case and assess whether the insurer applied the correct legal standards.

Time Limits and Dispute Resolution

You must lodge a complaint with SIRA within 28 days of the insurer's decision. If you miss this deadline, you may lose the right to challenge the decision. SIRA typically aims to resolve complaints within 28 days, but complex cases may take longer.

If SIRA upholds the insurer's decision, you may need to escalate the matter further. For example, you could request a review by the Personal Injury Commission (PIC) if there's a dispute over medical evidence. The PIC can also mediate disputes between claimants and insurers.

When to Seek Advice

Challenging an insurer's decision can be complex. Consider seeking legal advice if:

  • The insurer has denied your claim outright.
  • You're unsure whether your injury meets the 'threshold injury' definition.
  • You need help understanding the Motor Accident Guidelines.
  • You want to dispute a decision about weekly payments or treatment benefits.

A solicitor can help you prepare your complaint, ensure you meet all deadlines, and represent you if the matter escalates to a formal review.

Example Scenario

Imagine you were in a car accident in Ashfield and suffered a soft-tissue injury. Your insurer denied your claim, stating it was a 'threshold injury' and not eligible for weekly payments. You could challenge this decision by:

  1. Reviewing the insurer's letter to understand their reasoning.
  2. Gathering medical evidence to show your injury meets the threshold injury criteria.
  3. Lodging a complaint with SIRA, explaining why you believe the insurer's decision was incorrect.

Final Steps

If you're unsure whether you can challenge an insurer's decision, contact SIRA directly for guidance. Remember, you have the right to dispute a decision if you believe it was made incorrectly. For further assistance, complete the quick, no obligation enquiry form.

Next Steps

If you're in Ashfield and need help challenging an insurer's decision, take these actions:

  1. Gather all documents related to your claim.
  2. Review the insurer's decision letter.
  3. Lodge a complaint with SIRA within 28 days.
  4. Seek legal advice if the insurer's decision is upheld.

By following these steps, you can better understand your options under NSW's CTP scheme and challenge an insurer's decision if needed.
