Dispute Resolution for NSW CTP Claims Under the Motor Accident Injuries Act 2017

This article explains dispute resolution options for NSW CTP claims under the Motor Accident Injuries Act 2017, including internal reviews, mediation, and the Personal Injury Commission. It outlines practical steps, evidence requirements, and time limits for disputing compensation decisions in Bankstown.

Current as at 2 October 2026

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

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 disputing a compensation decision for a NSW Compulsory Third Party (CTP) motor accident claim, understanding your options under the Motor Accident Injuries Act 2017 is critical. This article explains the formal dispute resolution pathways available in Bankstown, including how to challenge a decision and what evidence matters. It also outlines time limits and when to seek legal advice.

Legal Framework for Disputing CTP Claims

Under the Motor Accident Injuries Act 2017, disputes over CTP compensation must follow specific procedures. The New South Wales government’s State Insurance Regulatory Authority (SIRA) oversees claims and provides guidelines for resolving disagreements. Key principles include:

  • Internal review: Insurers must first review disputed claims internally before external action is taken.
  • Mediation: SIRA offers a free mediation service to resolve disputes without litigation.
  • Personal Injury Commission (PIC): If mediation fails, claims can be escalated to the PIC for formal review.

The Motor Accident Injuries Regulation 2017 outlines timeframes for these steps, ensuring claims are resolved efficiently. For example, insurers must respond to disputes within 28 days of receiving a written request.

Practical Steps for Challenging a CTP Decision

To dispute a compensation decision, follow these steps:

  1. Review the insurer’s decision: Check the reasons provided for rejecting or adjusting your claim. Look for discrepancies between your evidence and the insurer’s assessment.
  1. Gather supporting evidence: This includes:
  • Medical records confirming your injury and treatment
  • Accident reports and witness statements
  • Income records to support claims for lost wages
  • Correspondence with the insurer
  1. Request an internal review: Write to the insurer formally disputing the decision. SIRA guidelines require claims to include specific details about the dispute.
  1. Seek mediation: If the insurer refuses to adjust the claim, apply for SIRA-mediated dispute resolution. Mediators will assess whether the insurer’s decision aligns with the Motor Accident Guidelines.
  1. Escalate to the PIC: If mediation fails, submit a formal application to the Personal Injury Commission. The PIC will review your case and may order the insurer to reconsider its decision.

Time Limits and When to Seek Advice

Disputes must be resolved within strict timeframes. For example:

  • Insurers must respond to disputes within 28 days (Motor Accident Injuries Regulation 2017 s 13)
  • Applications to the PIC must be made within 6 months of the insurer’s final decision

Missing these deadlines can permanently bar you from challenging a decision. If you’re unsure whether your claim is time-barred, seek legal advice immediately. Delays in gathering evidence or understanding your rights can jeopardize your ability to dispute.

Example: Disputing a Threshold Injury Claim

Suppose you were in a Bankstown car accident and received a claim for soft-tissue injuries. The insurer denied further benefits after 52 weeks, citing the Motor Accident Injuries Act 2017 s 4.4. You may dispute this by:

  • Providing medical evidence that your injury exceeds the 'threshold injury' definition
  • Arguing that your condition has worsened beyond the initial assessment
  • Seeking a second medical opinion to challenge the insurer’s conclusion

This example highlights how disputes often hinge on interpreting medical evidence and statutory definitions.

Next Steps

CTP disputes can be complex, especially when dealing with medical assessments and statutory deadlines. If you’re in Bankstown and facing a disagreement with your insurer, it’s essential to act promptly. Every claim depends on its own facts, and the available options may vary based on the accident date, injury type, and insurer response.
