[2013] NSWSC 629
defendant. Proceedings dismissed; plaintiff (Fire & Rescue NSW) to pay the first defendant's costs of the proceedings as agreed or assessed (see [37]).
The employer challenged a workers compensation medical appeal panel decision confirming a 10% permanent impairment award to a former firefighter, arguing the panel should have deducted for impairment 'due to any pre-existing condition' under s 323 because of the worker's pre-employment sun exposure. The Supreme Court held that s 323 requires evidence of a diagnosable pre-existing condition or abnormality that actually contributed to the impairment; mere prior exposure to sunlight or predisposition is not a 'pre-existing condition' for that purpose. The Court also held the panel's succinct reasons were adequate. Proceedings were dismissed and the employer ordered to pay costs.

Fire & Rescue New South Wales (the employer) challenged the decision of a medical appeal panel of the Workers Compensation Commission that confirmed an approved medical specialist's assessment awarding the former firefighter, Mr Clinen, 10% whole person impairment for disfigurement caused by skin cancer. The employer argued the panel erred in law or committed jurisdictional error by failing to make a deduction under s 323 of the Workplace Injury Management and Workers Compensation Act 1998 (NSW) (WIM) for any portion of impairment 'due to any pre-existing condition or abnormality'. The registrar had referred the AMS certificate to an appeal panel because the initial certificate did not provide adequate reasons on the s 323 point. The appeal panel considered the evidence (including the AMS, both parties' expert reports, and the worker’s history of sun exposure), concluded that although there was evidence of early-life sun exposure there was no evidence of a diagnosable prior injury or pre-existing condition of the skin prior to employment, and confirmed the AMS certificate (see [11], [15], [17]-[23], [27]-[31]). The employer brought judicial review in the Supreme Court seeking to set aside the panel's decision; Campbell J dismissed the proceedings and ordered the employer to pay the first defendant's costs (see [1]-[3], [31], [37]).
4 cited instruments linked from this judgment.
Two linked legal questions drove the decision. First, what does 'pre-existing condition or abnormality' mean in s 323 WIM: does it extend to facts such as prior exposure to a causal agent (sunlight) or to a predisposition, or does it require an identifiable diagnosable condition that pre-existed the employment? Second, were the appeal panel's reasons adequate such that the Supreme Court could not intervene for error on the face of the record or jurisdictional error?
Campbell J concluded that s 323 is engaged only where there is an established prior injury or a pre-existing 'condition or abnormality' that actually contributes to the impairment. That requires evidentiary support; assumption or mere antecedent circumstances are insufficient ([32]). The Court drew a distinction between causal circumstances (exposure to sunlight) and a clinical condition. While exposure is causative of skin cancer in a general medical-causal sense, s 323's ordinary statutory context, juxtaposed with 'previous injury', points to a more restricted meaning: a medical or like condition that is diagnosable and established prior to the employment in question ([34]-[35]). The appeal panel had asked and answered the relevant question on the evidence, it accepted there was early-life sun exposure but found no prior diagnosable skin condition nor treatment for such prior to the relevant employment, and so its conclusion that no deduction under s 323 was warranted was legally open and correct ([29]-[31], [33]-[35]).
On reasons, Campbell J applied established authority that reasons need only be sufficient to make clear the legal and factual foundations of the decision. The panel’s succinct reasons identified the statutory test, addressed the evidence, and explained why the evidence did not establish a pre-existing condition or abnormality; those reasons were adequate to discharge the panel’s legal duty ([36]).
Because the Court found no jurisdictional error and no error on the face of the record, relief was refused and the employer was ordered to pay costs ([31], [36]-[37]).
Before this decision, authorities such as Cole v Wenaline and Matthew Hall v Smart were canvassed in the context of what factual and causal connections were required under s 323 (see [15], [29], [32]-[33]). The Court accepted Schmidt J’s approach in Cole that s 323 requires a conclusion as to whether any proportion of impairment resulted from a previous injury or pre-existing condition and that the evidence must support any such connection ([32]).
After Campbell J’s decision in Fire & Rescue NSW v Clinen, the position is clarified, in this jurisdiction, that 'pre-existing condition' in s 323 should be read in the statutory context to mean a diagnosable medical condition or abnormality that contributed to the impairment. Mere exposure to a causal agent, or a predisposition, does not automatically engage s 323 without evidence of a pre-existing clinical condition that contributed to impairment ([34]-[35]). The decision reinforces the evidentiary threshold: a panel must be shown evidence of a prior condition that actually contributed to the assessed impairment before applying a deduction under s 323 ([32], [33]).
"[I]t is necessary to find a pre-existing abnormality or condition ... actually contributing to the impairment before s. 323 WIM is engaged. This conclusion has to be supported by evidence to that effect. Assumption will not suffice." ([32])
"The meaning of 'condition' in ordinary language may extend to include a prerequisite to something else... But the word 'condition' in the present statutory context, in my judgment, has a more limited meaning." ([34])
"The natural meaning in that restricted context of 'condition' is 'medical or like condition' in the sense of a diagnosable, or established, clinical entity." ([35])
"In my judgment the medical panel made the ground of its decision legally and factually clear in the appropriately succinct reasons provided. Those reasons are more than adequate to discharge the legal duty." ([36])
The decision governs cases where:
Under this precedent, a s 323 deduction will only be available where evidence supports a prior diagnosable condition or injury that actually contributed to the impairment. Mere evidence that the worker engaged in activities that contributed to causation (for example outdoor sporting activities, gardening, or early-life sun exposure) will not alone trigger a deduction ([22]-[23], [32]-[35]).
The judgment itself does not catalogue subsequent treatment by later courts. The decision engages familiar statutory interpretation and administrative law principles (necessity of identifying jurisdictional error, adequacy of reasons) and applies those principles to the particular statutory language of s 323 WIM. Any subsequent judicial treatment or citation post-dating this decision is not discussed in the judgment and would need to be researched separately in later reported decisions or citators.
The judgment establishes key interpretive points but leaves several practical and borderline issues unresolved:
In practice, employers and insurers seeking s 323 deductions should ensure robust pre-employment or pre-injury medical evidence is available that identifies and quantifies any pre-existing diagnosable condition or abnormality and its contribution to current impairment. Claimants and panels can rely on this decision to resist deductions founded merely on antecedent exposure or predisposition absent established clinical evidence.
Judgment 1The plaintiff employed the first defendant in work to the nature of which skin cancer may be due. I will refer to the plaintiff as the employer and the first defendant as the worker. 2The employer seeks to have the decision of a medical appeal panel (the second defendant), constituted under s 328 Workplace Injury Management and Workers Compensation Act 1998 (NSW) ("WIM"), set aside, and also seeks remitter of the matter to the Registrar of the Workers Compensation Commission (the third defendant), for further reference to an appeal panel for determination according law. 3In accordance with convention, the second and third defendants have filed submitting appearances. 4The error identified, according to the employer's argument, is an error of law at Glass JA's "third stage" as discussed in Azzopardi v Tasman UEB Industries Ltd (1985) 4 NSWLR 139, by reference, inter alia, to Hope v Bathurst City Council (1980) 144 CLR 1 at 7. His Honour explained the position as follows at 157: At the third stage when the law correctly stated is applied to the facts found in order to produce a conclusion error may intrude again. An erroneous conclusion that facts properly determined fail to satisfy a statutory test, for example, injury arising out of the cause of employment, substantial interruption to journey, or failure to provide suitable employment will ordinarily be an erroneous conclusion of fact. It is only in marginal cases that the statutory test is satisfied or not satisfied as a matter of law, because no other application is reasonably open (citations omitted). Accordingly this Court will not entertain unexplained perversity of result as a ground for intervention although it will correct perverse or unreasonable applications of law to the facts found. 5That statement was made in relation to the Court of Appeal's powers on an appeal from the former Workers Compensation Commission limited to a grievance "in point of law". In the present context, the employer has to establish that the error, if made good at all, is either jurisdictional error or error on the face of the record. 6Alternatively, the employer relies upon inadequacy of the reasons given by the appeal panel for its decision. Basten JA has suggested that because the record includes the reasons for the impugned decision (s 69(4) Supreme Court Act 1970 (NSW)) a successful challenge on this ground "will inevitably be an error of law on the face of the record": Allianz Australia Insurance Ltd v Kerr [2012] NSWCA 13; 60 MVR 194 at 209 [61]; Campbelltown City Council v Vegan [2006] NSWCA 284; 67 NSWLR 372 at 399 [130]. 7It needs to be borne in mind, as Mason J put it in Hope at 7, that "special considerations apply when we are confronted with a statute which on examination is found to use words according to their common understanding and the question is whether the facts as found fall within these words". In such a case the question will be one of fact, not law. Such a conclusion in the present case would exclude error of law on the face of the record, but not necessarily jurisdictional error.
Legislative framework 8Medical disputes and workers compensation claims are, in the first instance, resolved by assessment by an approved medical specialist, giving a certificate under s 325 WIM. (See part 7 ss.319 to 331 WIM). A medical dispute, as defined by s 319 WIM, extends to a dispute between a worker and an employer about "the degree of permanent impairment of the worker as a result of an injury" and, "whether any proportion of permanent impairment is due to any previous injury or pre-existing condition or abnormality, and the extent of that proportion": s 319(c),(d) WIM. 9Section 323 WIM is in the following terms: (1) In assessing the degree of permanent impairment resulting from an injury, there is to be a deduction for any proportion of the impairment that is due to any previous injury (whether or not it is an injury for which compensation has been paid or is payable under Division 4 of Part 3 of the 1987 Act) or that is due to any pre-existing condition or abnormality. (2) If the extent of a deduction under this section (or a part of it) will be difficult or costly to determine (because, for example, of the absence of medical evidence), it is to be assumed (for the purpose of avoiding disputation) that the deduction (or the relevant part of it) is 10% of the impairment, unless this assumption is at odds with the available evidence. Note. So if the degree of permanent impairment is assessed as 30% and subsection (2) operates to require a 10% reduction in that impairment to be assumed, the degree of permanent impairment is reduced from 30% to 27% (a reduction of 10%). (3) The reference in subsection (2) to medical evidence is a reference to medical evidence accepted or preferred by the approved medical specialist in connection with the medical assessment of the matter. (4) The WorkCover Guidelines may make provision for or with respect to the determination of the deduction required by this section. ... Note. Section 68B of the 1987 Act makes provision for how this section applies for the purpose of calculating workers compensation lump sum benefits for permanent impairment and associated pain and suffering in cases to which section 15, 16, 17 or 22 of the 1987 Act applies. This provision is central to the issue between the employer and the worker in the present case. Section 68B Workers Compensation Act 1987 (NSW) ("WCA"), so far as material, provides: (2) When determining the compensation payable by an employer in a case in which section 15 applies (disease of such a nature as to be contracted by a gradual process), section 323 of the 1998 Act applies to that compensation subject to the following: (a) there is to be no deduction under section 323 of the 1998 Act for any proportion of the permanent impairment that is due to the worker's employment in previous relevant employment (as defined in paragraph (b)) except any such proportion for which compensation under this Division (as in force at any time) or section 16 of the former Act has been paid or is payable, (b) for the purposes of paragraph (a), "previous relevant employment" is employment to the nature of which the disease was due by a previous employer who is liable under section 15 to contribute in respect of the compensation being determined (or who would be so liable if the requirement to contribute were not limited to employers who employed the worker during a particular period), (c) in the case of permanent impairment of the back, neck or pelvis, a reference in this subsection to previous relevant employment is limited to employment after the commencement of this Act. (3) When determining the compensation payable by an employer in a case in which section 16 applies (an injury that consists in the aggravation, acceleration, exacerbation or deterioration of a disease), section 323 of the 1998 Act applies to that compensation subject to the following: (a) there is to be no deduction under section 323 of the 1998 Act for any proportion of the impairment that is due to the worker's employment in previous relevant employment (as defined in paragraph (b)) except any such proportion for which compensation under this Division (as in force at any time) or section 16 of the former Act has been paid or is payable, (b) for the purposes of paragraph (a), "previous relevant employment" is employment that was a substantial contributing factor to the aggravation, acceleration, exacerbation or deterioration by a previous employer who is liable under section 16 to contribute in respect of the compensation being determined (or who would be so liable if the requirement to contribute were not limited to employers who employed the worker during a particular period), (c) in the case of permanent impairment of the back, neck or pelvis, a reference in this subsection to previous relevant employment is limited to employment after the commencement of this Act. (Emphasis in the original) 10I will deal with the background facts in a little more detail below, but it is convenient to point out now that the employer and the worker were not in dispute about the question of whether the worker suffered permanent impairment resulting from an injury. Rather, their dispute was whether any portion of the worker's impairment was "due to any pre-existing condition or abnormality". 11In the first instance that dispute had been resolved by an approved medical specialist, Dr. Allan Mears, in favour of the worker. He certified that the worker suffered from a whole person impairment of 10 per cent made up of 5 per cent whole person impairment relating to facial disfigurement, and 5 per cent whole person impairment relating to bodily disfigurement. In the course of his reasons he answered a question about the applicability of s 323 WIM in the following terms: There is no loss of efficient use or Whole Person Impairment due to a previous injury, pre-existing condition or abnormality [reasons at 8(e)]. 12Section 327 WIM permits an appeal against a medical assessment if certain conditions expressed in the section are satisfied. The available grounds are limited, but include a complaint that "the medical assessment certificate contains a demonstrable error": s 327(3)(d) WIM. 13An appeal is to be made by application to the Registrar of the Workers Compensation Commission, and "is not to proceed unless the Registrar is satisfied that, on the face of the application and any submissions made to the Registrar, at least one of the grounds for appeal specified in subsection (3) has been made out": s327(4) WIM. 14In the present case, the Registrar was satisfied that the medical assessment certificate contained a demonstrable error in that the s 323 finding I have referred to above was not supported by adequate reasons. The appeal was referred to a medical appeal panel in accordance with s328 WIM, constituted by two approved medical specialists and one arbitrator, each of whom was "chosen by the Registrar", or rather in this case, the Registrar's delegate.
The decision of the medical appeal panel 15Arbitrator Eraine Grotte, Dr Susanne Freeman, and Dr William Walker constituted the appeal panel. After reviewing the evidence and submissions provided by each of the parties, the appeal panel, in their unanimous decision, made certain findings and gave certain reasons. The central part of their reasoning process, relevant for present purposes, may be found at [27] - [31]: 27. Section 323(1) of the 1998 Act provides there is to be a deduction for "any proportion of the impairment that is due to any previous injury... or that is due to any pre-existing condition or abnormality" 28. In order to make a deduction the Panel must be satisfied the pre-existing condition, injury or abnormality is an ingredient in the overall permanent impairment (Moran v Thompson Adsett & Partners Pty Ltd (1996) 13 NSWCCR 484 and D'Aelo v Ambulance Service of New South Wales (1996) NSWCCR 139). This principle was confirmed by [her] Honour Justice Schmidt in Cole v Wenaline Pty Ltd (2010) NSWSC 78 where [her] Honour stated "Section 323 requires that a conclusion be reached as to whether or not any proportion of permanent impairment resulted from an earlier injury, pre-existing condition or abnormality". 29. Whilst there may be evidence of exposure to the sun in Mr Clinen's early years, there is no evidence of an earlier injury, pre-existing condition or abnormality. There is no evidence before the Panel, nor was there any evidence before the AMS, of any injury, condition or abnormality in respect of Mr Clinen's skin on his face or body that occurred prior to the commencement of his employment with the Appellant Employer. There is no evidence before the Panel, nor was there any evidence before the AMS, that Mr Clinen received any treatment for skin cancers/disorders/ disfigurement prior to his employment with the Appellant Employer. 30. The Panel is satisfied that there is no basis to make any deduction under section 323 of the 1998 Act. 31. For these reasons, the Panel has therefore determined that the Medical Assessment Certificate dated 30 August 2012 given in this matter should be confirmed. 16The panel's powers under s 328 WIM include the power to confirm the certificate of assessment given in connection with the medical assessment appealed against, which is the power exercised in this particular case.
Short factual background 17The worker was born on 23rd August 1930 and accordingly was 82 years of age on the date of the decision of the appeal panel. He joined the employer's service on 1st April 1955 at the age of 24 and retired on 26th February 1988. During his 33 years service he mainly worked on Sydney's northern beaches and worked outdoors most of the time. He was rostered on rotating shifts including evening and night work, but as part of his daytime uniform he used to wear short-sleeved shirts and shorts. During the period of his service no broad brimmed hat was supplied, rather he wore a peaked cap, and sun block was not provided nor used by him. 18The worker had attained the rank of Station Officer during the last 18 years of his service. 19The worker was first referred to a dermatologist in the late 1970s or early 1980s. A skin cancer was removed from the worker's forehead. Cancer treatment became "an ongoing job". 20A claim for lump sum compensation for permanent impairment was made on behalf of the worker by his solicitor's letter dated 11th April 2011. The claim was based upon the "disease provisions" (see ss.15 and 16 WCA) and the date of the claim was said to be the deemed date of injury: see ss.15(1)(a)(ii) and 16(1)(a)(ii) WCA. A specialist medical report of Dr. Derrick J Adendorff was provided in support of the claim. 21It was not clear which of the disease provisions was relied upon. The answers given by Dr. Adendorff to certain rolled up questions were ambiguous to the extent the expert's affirmative answer to questions seemed to accept that the worker's injury was both "a disease of gradual process" and "an aggravation of a disease of gradual process" arising from the worker's work duties. 22The worker was examined by Dr. Stephen Shumack at the request of the employer. The history recorded by Dr. Shumack included the following: He undertook the usual outdoor activities as a child in Ashfield, including cricket and football. He likes swimming and did a fair bit of gardening up until recent years. He does have an outdoor pool in his house at North Curl Curl. 23Dr. Shumack regarded the worker's condition as "attributable to accumulated sun exposure". 24Dr. Shumack attributed most of that accumulated sun exposure to non-work activities. He was asked the following question and provided the answer below: 8. Is there evidence of a pre-existing condition? If so, has this condition been exacerbated by [the worker's] employment? Please provide details. The pre-existing condition is pre-existing sun exposure. So in other words, further sun exposure sustained in the workplace environment has exacerbated [the worker's] underlying condition associated with pre-existing sun exposure prior to and away from his workplace environment. (Emphasis added.)
The submissions of the parties 25The main arguments of Mr. J.L. Sharpe of counsel, who appeared for the employer, have been summarised at [4] - [6] above. He also relied upon two decisions of Schmidt J: first, Cole v Wenaline Pty Ltd [2010] NSWSC 78 at [29] - [30]; secondly, Elcheikh v Diamond Formwork (NSW) Pty Ltd (in liq) [2013] NSWSC 365 at [88] - [89] and [95]. He argued that the error of law he had identified was jurisdictional error, at least in the sense, by reference to the passage from the reasons I have set out above at [15], that the appeal panel, if his argument was accepted, had either asked itself the wrong question or identified a wrong issue. 26To the extent to which the argument was based upon the inadequacy of the appeal panel's reasons, learned counsel acknowledged that the natural remedy for failure to exercise a statutory power to provide reasons for a decision was an order in the nature of mandamus. Although no such relief was sought in the amended summons, the plaintiff relied upon Rule 36.1 Uniform Civil Procedure Rules 2005. 27Mr. T.R. Edwards of counsel, who appeared for the worker, argued that the plaintiff had not demonstrated jurisdictional error or error on the face of the record. Counsel reminded the Court that the supervisory jurisdiction is essentially concerned with whether the appeal panel had properly applied the law and not with the process of making the particular findings of fact upon which the appeal panel had acted: Attorney General (NSW) v Quin [1990] HCA 21; 170 CLR 1 at [35] - [36] per Brennan J (as his Honour then was). 28Learned counsel argued that the appeal panel's conclusion at [29] of its reasons (see [15] above) that exposure to the sun prior to the worker's employment with the employer did not equate with a pre-existing condition or abnormality was legally correct. As it happens, said Mr Edwards, the conclusion was also factually correct, although that consideration may not be germane to the exercise of the Court's powers. 29Mr. Edwards relied upon Matthew Hall Pty Ltd v Smart [2000] NSWCA 284; 21 NSWCCR 34 at [29] - [33] and [37], in particular, the statement by Giles JA at [37] that "a genetic pre-disposition to [a disease] is not the same as [the disease] condition.... for the purpose of [s 323]." 30Mr. Edwards argued that there was no inadequacy in the appeal panel reasons.
Determination 31In my judgment, the argument of the worker is correct. 32As Schmidt J pointed out in Cole and Elcheikh, it is necessary to find a pre-existing abnormality or condition, here the latter, actually contributing to the impairment before s. 323 WIM is engaged. This conclusion has to be supported by evidence to that effect. Assumption will not suffice. 33This case is a little different from Cole. There Schmidt J was concerned with the causal connection connoted by the phrase "due to". Her Honour made the pertinent observation that it was necessary for the evidence acceptable to the appeal panel to actually support the connection between a previous injury (here, pre-existing abnormality or condition) and the overall degree of impairment in the instant case. Here, as Mr. Edwards pointed out, I am concerned with a logically anterior question: did the evidence of Dr. Shumack, which the appeal panel seemed to accept, that there was exposure to the sun in the worker's early years, mandate a finding of pre-existing condition or abnormality within s 323 WIM as the only legally sustainable conclusion? In my judgment, it did not. 34The analysis of Giles JA in Smart, to which I have referred, supports a legal distinction between a medical condition and the circumstance giving rise to it. The meaning of "condition" in ordinary language may extend to include a prerequisite to something else. The worker's exposure to sunlight in his youth, in that broad sense, is a pre-existing condition. But the word "condition" in the present statutory context, in my judgment, has a more limited meaning. In the context of legal causation, as with the meaning of the phrase "due to", one may refer to any one of the necessary "conditions" giving rise to a consequence as a cause, or prerequisite, of it. As a matter of causation, the worker's skin cancer is due to his exposure to sunlight, including during his youth before the commencement of his employment with the employer. But causation is not the presently relevant context. 35The context here is provided by s 323 and arises from the juxtaposition of words "previous injury", with "pre-existing condition or abnormality". The natural meaning in that restricted context of "condition" is "medical or like condition" in the sense of a diagnosable, or established, clinical entity c.f. Simeon Wines Ltd v. Bobos [2004] NSWCA 342 at [17] per Sheller JA, Santow JA and Young CJ in Eq. (as he then was) agreeing. This, in effect, is what the medical appeal panel decided in the portion of its reasons set out above at [15]. This conclusion involves no jurisdictional error in the sense of either identifying a wrong issue, or posing the wrong question; or error of law on the face of the record, by misapplying the law. Far from being an error of law at Glass JA's third stage, in my view the appeal panel's decision was not only legally open, but also legally correct. For what it is worth, the contrary conclusion, for which the employer contended before the appeal panel was not open on the evidence as the appeal panel, in my view correctly, decided. 36The legal duty of the medical panel to give reasons for it's decisions and its content are discussed by Basten JA in Vegan from 391 [98] to 399 [129], especially at 397 at [121] - [122]. It is not necessary to rehearse that discussion to decide the present case. In my judgment the medical panel made the ground of its decision legally and factually clear in the appropriately succinct reasons provided. Those reasons are more than adequate to discharge the legal duty. 37My orders are: (1)Proceedings dismissed; (2)Plaintiff to pay the first defendant's costs of the proceedings after they have been agreed or assessed.
