Dispute resolution under the SIRA Motor Accident Guidelines

Part 7 of the Guidelines supports the administration of the CTP scheme by establishing clear processes for dispute resolution. It aims to ensure that disputes are resolved as quickly, fairly, and cost-effectively as possible.

Before a dispute reaches the PIC, the Guidelines usually require the insurer to undertake a formal internal review of their original decision to see if the dispute can be resolved early.

When a claimant requests an internal review, the insurer is bound by the Guidelines to respond within specific timeframes (commonly acknowledging the request within two business days). The Guidelines state that the review must be conducted by someone with the appropriate skills and experience, and crucially, the reviewer must not have been involved in making or advising on the initial decision.

During the review, the insurer must consider any new information provided. The Guidelines set out strict maximum periods for completing the review (often 14 to 21 days depending on the dispute type, though extensions can apply if new information is requested).

The Guidelines require insurers to notify the claimant of the outcome of an internal review in writing. This notice must clearly state the reviewer’s decision, the reasons for that decision (with reference to the evidence relied upon), and the consequences of the decision on the claimant’s entitlements.

Importantly, the insurer must also provide information about the claimant’s right to lodge a dispute with the Personal Injury Commission if they remain dissatisfied.

If the internal review does not resolve the issue, or if the insurer fails to complete the review within the required timeframe, the Guidelines and the Act provide pathways to escalate the dispute to the PIC. The PIC handles various matters including merit reviews and medical assessments.

The Guidelines do not reward volume for its own sake. A better dispute bundle usually matches the evidence to the exact insurer reason. That can mean attaching the decision notice, a short chronology, treating records that answer the stated issue, and any focused documents about earnings, certificates, or treatment requests.

If the dispute is about stopped weekly payments, include the cessation letter, current certificates, and earning records. If it is about treatment refusal, include the treating recommendation and records that explain why the treatment is reasonable and necessary. If it is about threshold injury, make sure the medical material actually addresses the statutory definition and the insurer's stated reasoning.

Useful next-step pages include weekly payments stopped, treatment refused, threshold injury dispute, capacity for work disputes, and PAWE calculation.

Sometimes the real problem is not just the original insurer decision but the insurer's failure to complete the internal review properly or on time. That matters because missed review timeframes can affect when and how the matter can move to the PIC.

In practice, it helps to preserve the review request itself, proof of when it was sent, any acknowledgement, and any later correspondence showing silence, adjournment requests, or incomplete reasons. If weekly benefits are being affected while the review stalls, move quickly and align the file with internal review, PIC, and the correct dispute stream guidance.

A practical problem in many NSW CTP disputes is not lack of evidence but putting the dispute into the wrong bucket. The review and PIC pathway can change depending on whether the real issue is treatment, work capacity, PAWE, threshold injury, WPI, or another medical question.

That matters because the best evidence for one stream may do very little work in another. Earnings documents help with PAWE and weekly payments, but they do not replace medical reasoning in a threshold or WPI dispute. Likewise, a strong specialist report may still leave a merit-review problem underprepared if the earnings records, chronology, or insurer decision notices are missing.

Before escalating, it is usually worth cross-checking the matter against merit review vs medical assessment, weekly payments stopped, capacity for work disputes, threshold injury disputes, and WPI disputes so the escalation is built around the issue that actually needs deciding.

The handoff point between internal review and PIC is often where otherwise decent disputes lose momentum. A stronger handoff usually includes the original decision, the review request, the review outcome or delay evidence, a short chronology, and a bundle organised around the exact issue the PIC is being asked to decide.

That sounds simple, but many files still arrive with too much general claim history and not enough issue-specific structure. For example, a threshold dispute should usually foreground the diagnosis and classification evidence, while a PAWE or weekly-payments dispute should foreground certificates, work history, and earnings records. The more clearly the bundle tells the decision-maker what the fight is about, the better.

Useful pathway pages for building that handoff include internal review, internal review process steps, PIC overview, and PIC filing guidance.

Some insurer letters appear to be one decision but in substance contain several issues at once. A stopped-benefits notice may rely on work-capacity reasoning, certificate criticism, and threshold or treatment commentary all in the same document. If the claimant answers only one of those points, the dispute can remain underprepared even if some evidence is strong.

That is why mixed disputes usually need to be broken into their real parts early. Weekly-benefits and PAWE issues often need merit-review style thinking, while threshold, WPI, and some treatment issues usually need more medical-pathway discipline. Keeping the evidence separated avoids the common mistake of sending excellent medical material into an earnings fight, or vice versa.

To untangle those problems, it often helps to work across weekly payments stopped, capacity for work disputes, treatment refused, PAWE calculation, and merit review vs medical assessment before deciding how the escalation should be framed.

Before lodging with the PIC, it helps to prepare a one-page dispute map. Keep five rows: the insurer's exact reason, the legal test being applied, your best evidence answering that test, what outcome you seek, and what deadline now applies. That format quickly exposes where the file is still thin.

In many cases this one-page map is where claimants discover that a strong medical narrative has been filed into an earnings dispute, or that good earnings evidence has been filed without answering a threshold classification issue. Fixing that mismatch before escalation usually saves weeks of avoidable delay.
