When Can a CTP Insurer Change the Assessor?

Under the Motor Accident Injuries Act 2017 (MAIA), a CTP insurer may replace an assessor if there is a legitimate reason to believe the current assessor’s findings are unreliable, biased, or unsuitable for the claim. This includes situations where the assessor has a conflict of interest, lacks the necessary expertise, or the claimant has raised concerns about the assessment process. However, insurers must act within the legal framework to ensure fairness and transparency.

Legal Protections for Claimants

Claimants have the right to challenge an assessor change if they believe it is done without justification. Under the MAIA, insurers must provide a clear explanation for any change and ensure the new assessor has the appropriate qualifications. If a claimant feels the change undermines their claim, they may request a review or escalate the matter to the NSW Civil and Administrative Tribunal (NCAT) or the NSW Supreme Court.

Practical Steps and Evidence

When an assessor change occurs, claimants should:

  • Request a written explanation from the insurer detailing the reason for the change.
  • Verify the new assessor’s credentials and experience.
  • Document any concerns or discrepancies in the assessment process.
  • Seek independent medical opinions if the new assessment contradicts prior findings.

Evidence such as medical records, correspondence with the insurer, and witness statements may be crucial in disputes. SIRA guidelines emphasize that claimants must be treated fairly and have access to all relevant information.

Time Limits and Dispute Options

There is no specific time limit for disputing an assessor change, but delays can impact the claim’s progress. Claimants should act promptly to challenge decisions, especially if the new assessment reduces benefits or alters the claim’s outcome. Disputes may also arise if the insurer fails to follow proper procedures, such as not providing adequate notice of the change.

Real-World Example

In a 2023 case, a claimant contested an assessor change after the insurer replaced their independent medical expert without prior notice. The court ruled in the claimant’s favor, emphasizing that insurers must justify changes and ensure claimants are not disadvantaged. This highlights the importance of transparency and procedural fairness.

When to Seek Advice
