Roundabout collisions often lead to disputes over injury severity, fault and compensation under NSW's Compulsory Third Party (CTP) scheme. This article explains how claimants can resolve disagreements with insurers or the State Insurance Regulatory Authority (SIRA) through formal processes. Key options include internal reviews, mediation and legal challenges, with practical steps to support your case.

How CTP Disputes Arise in Roundabout Collisions

Disputes typically occur when claimants believe their injuries are more severe than classified, or that the insurer has undervalued their claim. Roundabout accidents may involve complex factors like speed, visibility and right-of-way, leading to disagreements over fault or injury thresholds. SIRA's guidelines on 'threshold injuries' and 'whole person impairment' are critical in determining entitlements.

SIRA's Role in Resolving CTP Disputes

SIRA handles claims under the Motor Accident Injuries Act 2017. If you disagree with an insurer's assessment, you can:

  • Request an internal review of the claim decision
  • Submit a formal objection to SIRA
  • Seek mediation through the NSW Civil and Administrative Tribunal (NCAT)

SIRA's 'What you can claim' page outlines benefits for soft tissue injuries, including weekly income payments and treatment costs. Disputes over these benefits often require medical evidence showing the injury meets the 'spinal nerve-root' criteria in the Motor Accident Guidelines.

Practical Steps for Roundabout Collision Claims

  1. Document the accident: Obtain police reports, witness statements and photographs of the scene. Roundabout collisions may involve multiple vehicles, so detailed records of vehicle positions and traffic signs are crucial.
  2. Medical evidence: Secure medical records from GPs, specialists and physiotherapists. For soft tissue injuries, ensure doctors note neurological signs like radiculopathy as required by the guidelines.
  3. Claim forms: Complete SIRA's claim forms accurately, specifying all injuries and treatment received. Disputes often arise from incomplete or ambiguous submissions.

Time Limits and Dispute Resolution Pathways

CTP claimants have 52 weeks from the accident date to claim certain benefits under the Act. After this period, weekly payments may stop unless the injury meets whole person impairment thresholds. If disputes persist, claimants can:

  • Apply for an internal review within 28 days of the decision
  • Lodge a formal objection with SIRA within 28 days
  • Request mediation through NCAT

The Personal Injury Commission (PIC) may also review medical disputes. However, challenges to SIRA decisions do not guarantee a change. Claimants should note that the PIC's role is to assess medical evidence, not to overturn SIRA's financial decisions.

Hypothetical Example: Dispute Over Soft Tissue Injury

A cyclist collides at a roundabout and sustains a bruised hamstring. The insurer classifies this as a 'threshold injury' under the 52-week benefit rules. The claimant argues the injury caused ongoing pain and reduced mobility, meeting the 'whole person impairment' threshold. To resolve this, the claimant must provide medical evidence showing the injury meets the spinal nerve-root criteria in the guidelines. SIRA may then refer the case to a medical expert for review.

When to Seek Legal Advice

Disputes over fault, injury classification or benefit amounts often require legal input. A solicitor can help draft formal objections, challenge medical assessments or negotiate with insurers. However, legal action is typically a last resort under the CTP scheme.

Next Steps for Claimants

If you're facing a dispute over your roundabout collision claim, the first step is to request an internal review of the insurer's decision. Gather all medical records, accident reports and correspondence with the insurer. For complex disputes, legal advice may be necessary to challenge SIRA's assessment or pursue additional remedies.
