[2017] NSWSC 1638
plaintiff. Decision of the Medical Assessors Review Panel dated 25 February 2017 set aside; matters remitted to the State Insurance Regulatory Authority for reallocation to a differently constituted Medical...
The insurer challenged a medical review panel's decision that raised the claimant's impairment rating above the statutory threshold for non-economic loss. The Supreme Court found the panel had made a key factual finding (that an earlier assessor had found a resolved right shoulder injury) which was unsupported by any of the assessor's certificates or other material. That false premise led the panel to decline to apply the Guidelines' rule about using the contralateral joint as a baseline; the panel also failed to explain the path of reasoning and did not properly undertake its own clinical assessment. Those errors amounted to errors of law on the face of the record. The court quashed the panel's decision and remitted the matter to be reallocated to a differently constituted panel for a fresh assessment.

A claimant, Mr Pillay, was injured in a motor vehicle accident on 7 October 2014. He underwent medical assessment processes under the Motor Accidents Compensation Act 1999 (NSW) (the MACA) to determine whole person impairment (WPI) for non-economic loss. Assessor Dr Geoffrey Boyce issued certificates (10 November 2015 and 20 September 2016) that ultimately supported a 5% WPI for cervical spine and later a 5% WPI for left shoulder. A combined certificate (29 September 2016) recorded total WPI of 10% (5% cervical + 5% left shoulder).
The claimant sought review under s 63 MACA. A Medical Assessors Review Panel (the Panel) comprised of three assessors issued a review certificate (25 February 2017) that concluded the left shoulder injury produced 6% WPI (a change from the 5%), and, when combined with the earlier cervical assessment, produced total WPI of 11%, thereby triggering entitlement to damages for non-economic loss. The Panel's reasons included statements that the right shoulder was not an 'uninjured' joint and that Assessor Boyce had 'found' a resolved right shoulder injury in his earlier certificate.
The insurer, CIC Allianz Insurance Limited, commenced judicial review in the NSW Supreme Court, alleging the Panel: (1) reached findings without evidential support; (2) failed to apply the Guidelines for the Assessment of the Degree of Permanent Impairment (1 October 2007), specifically clause 2.5; (3) failed to give adequate reasons that disclosed the path of reasoning; (4) failed to undertake its own assessment; and (5) that the court should nevertheless refuse relief on discretionary grounds. Bellew J found in favour of the insurer on the principal grounds, set aside the Panel's decision, and remitted the matter to the Authority for allocation to a differently constituted Panel for a fresh determination [orders].
Three interlocking legal principles governed the court's reasoning:
Findings must be supported by the material before the decision-maker. Bellew J found that the Panel ascribed to Assessor Boyce a finding, namely that the right shoulder injury had resolved, which did not, in fact, appear in Boyce's certificates. The Panel therefore reached a conclusion unsupported by the evidence before it. The court treated that as an error of law: a decision-maker cannot predicate conclusions on facts not found in the material before it [see the court's consideration in Ground 1].
Mandatory application of the Guidelines. Clause 1.3 of the Guidelines declares bold text as directive, and clause 2.5 is in bold. Clause 2.5 governs when the contralateral uninjured joint may serve as a baseline (and requires the rationale to be explained). The Panel declined to use the right shoulder ROM as a baseline because it concluded the right shoulder was not uninjured. Because that conclusion rested on the Panel's erroneous attribution to Assessor Boyce, the Panel failed properly to apply clause 2.5. The court treated that as an error of law (Ground 2).
Duty to give adequate reasons and conduct an independent assessment. Quoting Wingfoot, the court reiterated that a panel's written reasons must explain the actual path of reasoning so a court can see whether the opinion involves error of law. The Panel's certificate did not disclose the path of reasoning that led it to treat the right shoulder as 'not uninjured' or to reject Boyce's baseline figures; the certificate was conclusory and failed the Wingfoot standard (Ground 3). Further, s 63(3A) MACA requires a review to be a new assessment of the matters concerned; a panel must engage in clinical judgment on the material before it (Ground 4). The Panel's apparent blanket adoption of an asserted Boyce conclusion (which did not exist) demonstrated failure to engage in that fresh assessment.
Because these errors were material to the Panel's task, and because it could not be said a fresh assessment would inevitably reach the same result, the court quashed the Panel's decision and remitted the matter to a differently constituted panel rather than denying relief in the exercise of discretion [see the exercise of discretion discussion].
Before this decision the established law (as applied here) already contained the following propositions:
What this judgment emphasises and applies:
After the decision, practitioners can expect courts to scrutinise the factual basis of material findings in review panel reasons more strictly and to demand explicit application of Guidelines when the contralateral joint baseline is relevant.
"That conclusion was reached by the Panel in circumstances where there was no evidence to support it."
"The Panel's error constitutes an error of law."
Quoting Wingfoot: "The statement of reasons must explain the actual path of reasoning by which the Medical Panel in fact arrived at the opinion..."
"The Panel was required to engage in a process of clinical judgment having regard to the material which was before it."
"If the matter were remitted to a differently constituted Review Panel, that Review Panel would be required to make a fresh determination..."
(Each of the above passages is grounded in the court's analysis; the judgment records the Panel's problematic statements and Bellew J's responses at the cited analysis sections [see references to the Panel's reasons and the court's consideration].)
This decision will be engaged where:
In these scenarios, insurers or other affected parties have a strong basis to seek certiorari to quash the panel's decision and require remittal.
Within the judgment itself Bellew J applied established High Court and NSW authority (Wingfoot, Frost, Rutland, Sadsad, etc.) to articulate and apply the principles summarised above. The decision follows the line that reasons must disclose the panel's reasoning and that Guidelines are binding; it is consistent with prior NSW Supreme Court decisions (e.g., AAI v Fitzpatrick; Rutland) and will be cited subsequently as reinforcing the duty of panels not to base decisions on findings without evidential support.
Practitioners should note that courts will not treat arithmetic corrections or a single conceded error as a reason to deny relief where other identified legal errors affect the assessment process or the exercise of clinical judgment. In short, this decision strengthens earlier rulings that supervisors will quash review panel decisions where the statutory procedural and reasoning requirements are not met.
Degree of detail required in reasons for highly technical clinical judgments: Wingfoot sets a standard that the path of reasoning must be disclosed, but how granular must reasons be in every case for different specialties or complex impairment calculations? The judgment insists on more than conclusory statements but does not provide a template of minimum content.
Reliance on contemporaneous non-expert notes (e.g., osteopath records): The court emphasises that records of pain do not automatically equal 'injury' for impairment baseline purposes. However, the boundary between what constitutes sufficient evidence of a pre-existing 'injured' joint (so as to exclude use of a contralateral joint baseline) remains fact-sensitive and may require further elaboration in subsequent cases.
When is re-examination required? Bellew J accepted re-examination is not mandatory in every case. The factors that make re-examination necessary versus appropriate reliance on existing material remain to be fully articulated in a body of cases.
Remedy choice and remittal to a differently constituted panel: The court ordered remittal to a differently constituted panel. The circumstances in which a court will specify reconstitution of the decision-maker rather than remitting to the same panel require further clarification; this decision implies reconstitution is appropriate where the earlier panel's process is tainted.
Interaction with practical pressures: The decision tightens scrutiny on Panel reasons and application of Guidelines. How SIRA and panels adjust practice (longer, more detailed reasons; systematic explanations of baseline choices) and whether that imposes new resource or evidentiary burdens remains to be observed.
Conclusion
CIC Allianz Insurance Limited v Pillay is a clear reaffirmation that medical review panels operating under the MACA must base findings on material actually before them, must apply the Guidelines when mandatory, must explain the pathway of reasoning in line with Wingfoot, and must perform their own assessment by exercising clinical judgment. Failure in any of these respects can amount to error of law and justify quashing and remittal. Practitioners dealing with medical assessment reviews should ensure (a) evidential basis for all critical findings is available in the record; (b) clause 2.5 and other bolded Guideline directives are expressly considered; and (c) reasons disclose how the panel moved from evidence to conclusions.

INTRODUCTION
FACTUAL BACKGROUND
The first defendant's accident and subsequent medical assessment
The application by the first defendant for a review of the medical assessment
The determination of the Review Panel
*% WPI = percentage whole person impairment Determination Regarding the Degree of Whole Person Impairment of the Injured Person as a Result of the Injuries Cause by the Motor Accident. The total percentage whole person impairment for assessed injuries caused by the motor accident is 6%. The determination as to permanent impairment is made in accordance with the American Medical Association's Guides to the Evaluation of Permanent Impairment (Fourth Edition) and the Impairment Assessment Guidelines. Permanent impairment ratings take symptoms into account, however the percentage whole person permanent impairment is not a direct measure of disability. A finding of zero percent whole person impairment indicates that there was an injury caused by the motor accident and that there may be continuing symptoms, however, relevant Guides rate the associated impairment at zero %WPI. Permanent Impairment The Review Panel's findings in relation to the degree of permanent impairment of the injuries caused by the accident are different to the findings as stated in the Permanent Impairment Certificate issued by Assessor Boyce. The Panel found a different Permanent Impairment from the left shoulder injury. Accordingly the Review Panel has determined that this Certificate is to be revoked and a new Permanent Impairment certificate has been issued by the Review Panel.
