Statement of Principles concerning Dupuytren disease (Balance of Probabilities) (No. 10 of 2019)

The central concept is “Dupuytren disease” as defined in section 7(2) - a benign, progressive fibroproliferative disease of the palmar and digital fascia causing puckering, thickening, nodules, cords, and possible flexion contracture. It is coded to ICD‑10‑AM M72.0 but the definition in the SoP governs, not the code. “Death from Dupuytren disease” includes death where a terminal event (pneumonia, respiratory failure, cardiac arrest, circulatory failure, or cessation of brain function) was contributed to by the disease. The term “relevant service” is defined in the dictionary and has a restricted meaning: it covers eligible war service (other than operational service) under the VEA, defence service (other than hazardous service and British nuclear test defence service) under the VEA, and peacetime service under the MRCA. This means the SoP does not apply to operational service or hazardous service, where a different SoP (Reasonable Hypothesis) would be used. The factors themselves rest on several key measurements. “Pack‑years of cigarettes” is defined as twenty tailor‑made cigarettes per day for one year (or 7,300 cigarettes), with one gram of tobacco per cigarette. For factor 9(1) (smoking) the claimant must have smoked at least ten pack‑years before onset, commenced at least five years before onset, and if they stopped, onset must occur within five years of cessation. Alcohol consumption is expressed in grams per week: 200 grams equals twenty standard drinks (Australian standard of 10g alcohol per drink). The consumption must be for at least five consecutive years within the ten years before onset. Alternatively, “alcohol use disorder” or “alcoholic liver disease” (defined as steatohepatitis or cirrhosis due to chronic heavy consumption) are separate factors. “Trauma” is defined as a significant injury with symptoms or signs lasting at least seven days or sufficiently severe to warrant medical attention. For factor 9(5), trauma must be to the hand, wrist, or forearm of the affected side within one year before onset. For bilateral disease, factor 9(7) has special timing rules: the trauma must occur before onset, the disease first develops on the traumatised side, and it develops in both hands within one year following the trauma. “Clinically significant infection” is defined as flexor tenosynovitis or palmar abscess. The manual work factor (9(8) and 9(19)) requires a cumulative ten thousand hours of repetitive, strenuous or forceful activities, or use of hand‑held vibrating/percussive tools, before onset (and if ceased, onset within five years). That is a high threshold equivalent to roughly five years of full‑time work assuming 40 hours per week, 50 weeks per year. Medical conditions covered as standalone factors include diabetes mellitus, epilepsy, and treatment with vemurafenib (a cancer drug). For clinical worsening, the same factors apply but only to material contribution or aggravation where the disease was suffered or contracted before or during (but did not arise out of) relevant service (section 10(2)). This imposes a narrower window for worsening claims. The dictionary also defines “terminal event” and “alcoholic liver disease” and cross‑references MRCA and VEA.

The primary persons affected are veterans, members of the Australian Defence Force, and their dependants who make a claim for compensation or pension in relation to Dupuytren disease under the VEA or MRCA. Because the SoP applies only to claims under section 120B VEA and section 339 MRCA, it covers claims where the standard of proof is the balance of probabilities - that is, claims based on eligible war service (non‑operational), defence service (non‑hazardous), and peacetime service. Veterans with operational service or hazardous service are not directly affected by this particular SoP; they would be assessed under a Reasonable Hypothesis SoP (which may or may not contain identical factors). The SoP also affects decision‑makers, including delegates of the Repatriation Commission, the Military Rehabilitation and Compensation Commission, and the Veterans’ Review Board. They are legally bound to apply the factors in section 9 when determining whether Dupuytren disease is service‑related. The SoP effectively strips discretion to consider other causal theories not listed, so decision‑makers must mechanically test each factor against the evidence. Medical practitioners and specialists are affected insofar as their clinical records and opinions must address the specific definitions in the SoP (e.g., whether an infection qualifies as “clinically significant” as defined, whether trauma meets the seven‑day threshold). Compensation lawyers and advocates must advise claimants on the likelihood of satisfying any of the factors given the claimant’s service history and medical history. The SoP also indirectly affects the Department of Veterans’ Affairs and the broader taxpayer, because the factors influence the approval rate for claims and therefore the cost of the compensation scheme. The high thresholds in some factors (10,000 hours of manual work, 10 pack‑years of smoking, 200g/week alcohol for five years) mean that many claimants with less severe exposures may not qualify, potentially reducing claim volumes but increasing disputes over quantification of hours or grams. The SoP does not affect the general public or private medical providers except to the extent they must supply evidence in the specific format the SoP expects. Because it replaces the 2010 SoP, it also affects existing claimants with pending or lodged claims that had not been finally determined before 28 January 2019; they must now be assessed under this instrument (section 5 applies to claims under sections 120B and 339, which would cover current and future claims). For claims already finally determined, there is no reopening unless legislative provisions allow.

The SoP imposes no direct duties on private individuals; its duties are institutional. The Repatriation Medical Authority has a statutory duty under section 196B VEA to determine SoPs based on sound medical‑scientific evidence. Having done so, the RMA’s duty is satisfied. The key duty falls on decision‑makers, who must apply the factors in section 9 when deciding whether Dupuytren disease is related to relevant service. They may not substitute their own medical opinion for the RMA’s factors. This is explicit in the framework: the factors are conclusive on the question of connection once satisfied on the balance of probabilities. However, the decision‑maker retains the obligation to assess whether each claimed factor actually exists in the person’s case and whether it is related to relevant service (section 10(1)). For clinical worsening claims, the decision‑maker must also determine whether the disease was suffered or contracted before or during (but did not arise out of) service, and then whether a worsening factor resulted in material contribution. The claimant’s right is to have their claim determined in accordance with the SoP. If they can establish, on the balance of probabilities, that at least one factor exists and is service‑related, they are entitled to a determination that the disease is connected to service. That determination may lead to compensation, medical treatment, or other benefits under the VEA or MRCA. Section 11 provides a procedural right: if a factor refers to an injury or disease covered by another SoP (e.g., alcoholic liver disease has its own SoP), then the factors from that other SoP apply. This means a claimant does not need to re‑prove the other condition; they simply need to satisfy the other SoP’s factors, and those factors then are taken to establish the original factor in the Dupuytren SoP. This cross‑referencing reduces duplication. The SoP also creates a form of right to rely on clinical worsening where the disease pre‑existed service. Subsection 10(2) limits factors 9(12) to 9(23) to material contribution or aggravation, so the claimant does not need to prove the disease arose from service, only that it worsened due to a service‑related factor. This is a significant right for members who develop Dupuytren disease before service (e.g., while in civilian life) and then experience progression during peacetime service. The burden of proof rests with the claimant, but the standard is the balance of probabilities (more likely than not). The decision‑maker must give reasons if factors are rejected. No right of appeal is created by the SoP itself, but the underlying Acts provide review mechanisms.

The SoP itself does not create any penalties. It is an evidentiary instrument, not a penal regulation. Enforcement is achieved through the claims determination process rather than through fines or sanctions. If a claimant misrepresents facts to satisfy a factor (e.g., claiming 10,000 hours of manual work that never occurred), they may face penalties under the relevant legislation: knowingly making a false statement to obtain a benefit under the VEA is an offence under section 220 of that Act, carrying imprisonment for up to 12 months. Similarly, forging medical records or giving false evidence to the Veterans’ Review Board could attract criminal liability under the Criminal Code (Cth) or the general law of perjury. For decision‑makers, failing to apply the SoP correctly is not a penal matter but may constitute a reviewable error. The Administrative Appeals Tribunal and the courts can set aside decisions that are not made in accordance with the law, and the decision‑maker risk costs (in some jurisdictions) or adverse comments. However, there is no direct penalty for the Repatriation Medical Authority if the SoP is later found to be based on insufficient evidence; the instrument remains valid until revoked or amended. The enforcement of rights under the SoP is achieved through internal review (by the Veterans’ Review Board) and external review (by the Administrative Appeals Tribunal and the Federal Court). If the SoP is challenged as ultra vires (e.g., because the RMA misapplied the “sound medical‑scientific evidence” test), the court can declare the instrument invalid, but this is a remedy under administrative law, not a penalty. For practitioners and advisors, there is no regulatory penalty for misinterpreting the SoP, but professional negligence claims could arise if poor advice leads to a lost compensation claim. The SoP therefore enforces itself through the gatekeeping of compensation: only claims meeting the factors can succeed, which acts as a form of budgetary control by limiting eligible cases. There is no separate enforcement authority monitoring compliance with the SoP; it is applied by the Commissions and reviewed on a case‑by‑case basis.

The SoP is one component of the broader veterans' compensation framework. It interacts directly with the Veterans’ Entitlements Act 1986 and the Military Rehabilitation and Compensation Act 2004. Section 120B VEA requires that for claims where the standard of proof is the balance of probabilities, the decision‑maker must be satisfied of the connection between the disease and service in accordance with the relevant SoP. The SoP effectively supplants common law tests of causation for these claims. It also interacts with other SoPs through section 11: if a factor in section 9 refers to an injury or disease that has its own SoP (e.g., alcoholic liver disease), then that SoP is incorporated by reference. This creates a chain of causation: to prove the factor, the claimant may need to prove the underlying disease by its own set of factors. This can increase the evidentiary burden. The SoP refers to ICD‑10‑AM coding (tenth edition, 2017) for classification purposes, but the definition of the disease is not tied to that code; the code merely serves as the statistical classification. Changes to the ICD‑10‑AM in later editions do not automatically update the SoP, because subsection 7(4) specifically references the tenth edition. The SoP does not interact with state workers’ compensation laws, as it is exclusively a Commonwealth instrument. For veterans who also have private insurance or superannuation claims for total and permanent disablement, the SoP may influence medical assessments but does not bind private insurers. The SoP also interacts with the Disability Pension regime under the VEA and MRCA. A claim determined under the SoP can affect the rate of pension or the award of special rate disability pension. The SoP also interacts with the Safety, Rehabilitation and Compensation Act 1988 (SRCA) to the extent that peacetime service under the MRCA is involved; the MRCA itself provides links to the SRCA for some definitions, but the SoP specifically defines its own terms. The SoP does not override the legislation; it operates within the legislative boundaries. For example, section 120B VEA specifies that the SoP must be applied, but the underlying eligibility criteria for a pension (e.g., under section 13 VEA) remain. The SoP also does not affect criminal laws or the general law of contract. It does not create any civil liability. Its interaction with human rights instruments is indirect: by delineating factors that link disease to service, it can be argued to limit access to compensation for those whose disease arises from service but whose specific causation does not match a listed factor, potentially raising issues of discrimination. However, the SoP has been upheld as a valid legislative mechanism. The 2019 SoP repealed the 2010 SoP, so any reference to the earlier instrument in case law or administrative guidelines is no longer current for claims assessed after 28 January 2019.

This SoP, No. 10 of 2019, was made on 21 December 2018 and commenced on 28 January 2019. It repealed the earlier Statement of Principles concerning Dupuytren’s disease No. 58 of 2010 (registered as F2010L01671). The name change from “Dupuytren’s disease” to “Dupuytren disease” reflects modern medical terminology. The instrument is made under subsection 196B(3) of the VEA, which is the “Balance of Probabilities” stream. The RMA evaluates medical evidence from time to time and issues new SoPs when it considers that the available evidence justifies changes. The 2019 version introduced several new factors that were not in the 2010 version or revised thresholds. For instance, the smoking factor (9(1)) requires 10 pack‑years with a five‑year window for onset after cessation; the manual work factor (9(8)) requires a cumulative 10,000 hours; the bilateral disease factors (9(7), 9(18)) are new structural additions. The 2019 version also includes vemurafenib treatment as a factor (9(11), 9(22)), reflecting emerging evidence linking the drug to Dupuytren‑like reactions. The alcohol consumption factor now uses a five‑year consecutive period within ten years before onset, a more specific requirement than the previous wording. The dictionary definitions were updated, notably the definition of “trauma” now explicitly includes chemical, electrical, and thermal burns as examples. The SoP does not list any subsequent amendments; it remains in force as published. It is important to note that the Repatriation Medical Authority may issue further SoPs at any time if new medical evidence becomes available. SoPs are legislative instruments and are registered on the Federal Register of Legislation. They are disallowable instruments and subject to parliamentary scrutiny. The 2019 SoP replaced the 2010 SoP entirely, meaning any claim decided after 28 January 2019 must be assessed under the 2019 version, even if the claim relates to events that occurred under the earlier SoP. There is no transitional provision for pending claims; section 5 applies the instrument to any claim to which sections 120B or 339 apply, and the date of the claim is generally the relevant reference point. The amendment history from 2010 to 2019 shows the RMA’s shift to more quantitative factors (e.g., pack‑years, grams of alcohol, hours of manual work) rather than qualitative descriptions. This increases precision but also raises the evidentiary bar.

The SoP itself references no cases. The instrument is a legislative determination, not a court judgment. However, SoPs in general are frequently litigated in the Administrative Appeals Tribunal (AAT) and the Federal Court of Australia, with applicants challenging decisions that reject their claims based on factor analysis. Common arguments include that the RMA failed to base the SoP on sound medical‑scientific evidence, that the factors are ultra vires, or that the decision‑maker misapplied the factors to the facts. Without naming specific cases (the source does not name any), we can observe that Dupuytren disease claims have been the subject of AAT decisions under earlier SoPs. The 2019 SoP, with its high thresholds for manual work and smoking, may reduce successful claims but also invites more challenges regarding quantification of hours, accuracy of pack‑year calculations, and the interpretation of “clinically significant infection.” The bilaterality factors (9(7), 9(18)) could be contested where the sequence of development is unclear or where evidence of first development is weak. The clinical worsening factors may generate disputes over whether the disease suffered before or during service but did not arise out of service. The definition of “inability to obtain appropriate clinical management” (factor 23) is inherently vague and may be tested in litigation; claimants may argue that lack of access to surgery or medication qualifies, while decision‑makers may apply a narrow interpretation. The Federal Court has held that SoPs are binding and that decision‑makers cannot go behind them. This limits the scope for litigation on causation but shifts focus to fact‑finding. There is also potential for constitutional challenges to the RMA’s powers under section 196B, though none have succeeded to date. The sheer number of factors (23) means that each claim presents multiple factual questions, increasing the risk of administrative error. For claimants, the cost of litigation may outweigh the benefit, particularly for mild disease. The SoP is likely to be reviewed in the AAT in a stream of cases, but no landmark case is cited in the instrument. The absence of citation does not imply absence of litigation; rather, the SoP is meant to minimise litigation by standardising the causation question. Nevertheless, the complexity of definitions (e.g., “trauma” requiring symptoms lasting at least seven days) will continue to generate disputes.

Several traps lie in the wording. First, the temporal windows are strict. For traumatic onset, the trauma must occur within one year before the first clinical signs; for infection, three months. A claimant with a ten‑year old hand injury will not qualify under factor 9(5) unless the injury triggers the disease within the one‑year window. Second, for bilateral disease, the special factors (9(7) and 9(18)) require that the disease first develops on the side affected by trauma or infection, and that the other hand is affected within one year (trauma) or three months (infection). If both hands are affected but the first affected side is not the traumatised side, the factor does not apply, and the claimant cannot use the general trauma factor for bilateral disease. Third, the cumulative manual work factor demands 10,000 hours of specific hand activities. This is a very high bar. Note that the SoP does not require that the hours be continuous, but they must be performed before the clinical onset. If the person changes jobs or retires, and onset occurs more than five years after ceasing the activities, the factor does not apply (9(8) contains a cessation condition). Fourth, the smoking factor requires onset within five years of cessation. A long‑term smoker who stopped 15 years before developing Dupuytren cannot rely on past smoking unless they restart. Also, the ten pack‑year minimum may exclude lighter smokers. Fifth, the alcohol factor is keyed to a minimum of 200 grams per week for five consecutive years within the ten years before onset. Someone who drank heavily but not for a full five consecutive years will not satisfy factor 9(2). However, they might satisfy factor 9(3) (alcohol use disorder) or 9(4) (alcoholic liver disease), which do not have a consecutive‑year requirement. Sixth, “inability to obtain appropriate clinical management” (factor 23) is a catch‑all but is likely interpreted narrowly. It probably requires evidence that the veteran sought or needed treatment that was not available due to service circumstances, such as postings to remote areas. It does not include a mere delay in private treatment. Seventh, the cross‑referencing in section 11 can be a trap: to prove alcoholic liver disease, the claimant must satisfy the SoP for that condition, which may have its own demanding factors. Eighth, the “clinically significant infection” definition is limited to flexor tenosynovitis or palmar abscess. A minor cellulitis of the palm would not qualify. Ninth, the definition of “relevant service” excludes operational service, hazardous service, and British nuclear test defence service. Claimants with those service types must look to a Reasonable Hypothesis SoP. If a delegate mistakenly applies this SoP to an operational service claim, the decision is likely invalid. Tenth, the clinical worsening factors (9(12) - 9(23)) require that the disease was suffered or contracted before or during (but did not arise out of) service. This means the veteran must already have had Dupuytren disease before service or contracted it during service from a non‑service cause. If the disease first arose during service from a service‑related cause, the onset factors should be used, not the worsening factors. Finally, the instrument does not provide any deeming provisions for service‑relatedness if the factor is proven; it still requires that the factor itself be related to relevant service (section 10(1)). A factor like diabetes mellitus (9(9)) must be shown to be service‑related (e.g., due to Agent Orange exposure or service‑related obesity). Simply having diabetes is not enough.

For decision‑makers and delegates, compliance means following the structure of the SoP precisely. First, confirm that the claim is for Dupuytren disease as defined in section 7(2) and that it is being assessed under the balance of probabilities standard (non‑operational service or peacetime service). Second, identify whether the claim is for clinical onset or clinical worsening. Third, check each factor in section 9 to see if any might apply based on the evidence. For each potential factor, verify the temporal requirements: the factor must exist before the clinical onset (or worsening) and within the specified windows (e.g., one year for trauma, three months for infection). For smoking, calculate pack‑years: total cigarettes smoked divided by 7,300; ensure onset or worsening is within five years of cessation if the person stopped. For alcohol, calculate average grams per week over any five consecutive years in the ten years before onset. Obtain medical evidence confirming the disease diagnosis and timing of first symptoms. For manual work factor, total hours must be at least 10,000; consider using records of employment or detailed statements, but be cautious about self‑reported hours. If the claimant has bilateral disease, the special bilateral factors must be considered first; only if those are not satisfied might the general factors apply, but note that general trauma and infection factors (9(5) and 9(6)) apply to the affected side; they do not automatically cover bilateral. For diabetes, epilepsy, or vemurafenib treatment, obtain independent medical proof. For factor 23 (inability to obtain appropriate clinical management), require evidence that the veteran was unable to access treatment due to service circumstances, and that this inability contributed to the progression or onset. Document all findings in reasons, identifying which factor(s) are accepted or rejected, and why. For practitioners advising claimants, the compliance approach is to gather evidence early. Obtain a history of hand injuries, infections, occupation, sports, alcohol consumption, smoking habits, and medical records for diabetes, epilepsy, and prescriptions. Calculate pack‑years and alcohol grams meticulously. If the claimant did manual work, get a detailed description of tasks and tools, and estimate hours per week and total years. Keep in mind that the SoP uses the term “cumulative period of at least 10,000 hours”, so work history over decades can be aggregated. For clinical worsening claims, ensure you can establish the disease existed before service (or during service but from non‑service causes) and that a service‑related factor caused material worsening. It may be easier to rely on the worsening factors if the disease is pre‑existing and the service involves manual work, alcohol, or smoking. For claims involving alcohol, note that alcohol use disorder may be diagnosed without quantifying grams. For trauma, remember the seven‑day threshold: a cut that heals in three days is not trauma. Seek evidence of medical treatment. Finally, practitioners should be aware that the 2019 SoP has higher thresholds than the 2010 version; older advice based on the 2010 SoP may be obsolete. Regularly check the Federal Register for any later SoPs.
