Statement of Principles concerning electrical injury (Reasonable Hypothesis) (No. 41 of 2018)

This instrument is a legislative determination made by the Repatriation Medical Authority (RMA) under subsection 196B(2) of the Veterans' Entitlements Act 1986 (VEA). It sets out the factors that must exist before a reasonable hypothesis can be raised connecting electrical injury, or death from electrical injury, with the circumstances of a person's relevant service under the VEA or the Military Rehabilitation and Compensation Act 2004 (MRCA). The instrument does not create or define the standard of proof for veterans' claims; rather, it specifies the minimum factual conditions under which the statutory "reasonable hypothesis" test in section 120A of the VEA (or section 338 of the MRCA) can be satisfied. Mechanically, the RMA determines that there is sound medical-scientific evidence indicating that electrical injury and death from electrical injury can be related to relevant service (section 8). The instrument then lists, in section 9, the factors that must as a minimum exist: (1) exposure to electrical current at the time of clinical onset; (1A) exposure to an electric arc across the affected area of the body at the time of clinical onset; or (2) inability to obtain appropriate clinical management for electrical injury. Any such factor must be related to the person's relevant service (section 10). This is a binding administrative instrument: it controls what evidence the Repatriation Commission and the Veterans' Review Board (and subsequently the Administrative Appeals Tribunal) must accept as sufficient to raise a reasonable hypothesis. Its practical effect is to standardise and restrict the causal pathways for which a veteran can claim compensation for electrical injury. The instrument applies only to claims where section 120A of the VEA or section 338 of the MRCA applies (section 5) - that is, claims relating to operational, peacekeeping, hazardous, British nuclear test defence service (under VEA) or warlike and non-warlike service (under MRCA). It does not apply to claims under the Safety, Rehabilitation and Compensation Act 1988 or private workers' compensation schemes. By confining the recognised factors to these narrow categories - essentially direct exposure or failure of medical management - the instrument limits the range of service-related hypotheses that can succeed, reducing evidentiary disputes but also restricting compensation pathways. From a cost perspective, this favours the Commonwealth by channelling claims into predictable, medically defined boxes, reducing the scope for novel arguments. The instrument was originally made on 30 April 2018 and amended on 22 January 2024 (Amendment No. 13 of 2024), which added factor (1A) concerning electric arcs and revised the definition of electrical injury and the wording of factor (1). This is a compilation showing the law as at 22 January 2024.

The central concept is electrical injury, defined exhaustively in subsection 7(2). It means physical damage to the body as a direct result of the flow of electrical current through the body or across the body surface. The definition explicitly includes damage from an external manufactured source (including an implanted electrical device); being struck by lightning; being in the immediate vicinity of a lightning strike; electrical contact burns; and electrical flash burns. Critically, it excludes "any consequences from exposure to external electromagnetic radiation" (paragraph 7(2)(c)). This exclusion is notable: electromagnetic radiation injury (e.g., from radar, microwave transmitters, high-voltage power lines without direct contact) is not caught. The instrument also adopts ICD-10-AM codes T75.0 (electrical effects) and T75.4 (electrocution) but states that the meaning of electrical injury is that given in subsection (2), not merely the code (subsection 7(3)). This prevents reliance on a coding classification that might be broader than the instrument's definition. Death from electrical injury is separately addressed in subsection 7(5): it includes death from a terminal event or condition contributed to by the electrical injury. "Terminal event" is defined in the dictionary to mean the proximate or ultimate cause of death and includes pneumonia, respiratory failure, cardiac arrest, circulatory failure, or cessation of brain function. This list is inclusive, not exhaustive, allowing forensic flexibility but also creating uncertainty about what else qualifies. The reasonable hypothesis test itself is not defined in the instrument but is imported from the VEA. Under section 120A, a claim must be determined by reference to the relevant Statement of Principles: if the material raises a hypothesis that fits the template of the instrument, and the hypothesis is not contrary to the proved facts, then a reasonable hypothesis exists and the veteran is entitled to the benefit of the doubt. The instrument's factors are the minimum conditions; if none of the three factors exists, no reasonable hypothesis can be raised, regardless of other evidence. Relevant service is defined in the dictionary and includes operational service, peacekeeping service, hazardous service, British nuclear test defence service under the VEA, and warlike or non-warlike service under the MRCA. This is a closed list; other types of service, such as peacetime service under VEA or MRCA (which uses different standards), are not covered. The instrument further defines that any factor must be related to the relevant service. Subsection 10(2) contains a special rule for factor (2) (inability to obtain appropriate clinical management): it applies only to material contribution to, or aggravation of, an electrical injury that was suffered or contracted before or during (but did not arise out of) the person's relevant service. This means that if the injury arose out of service, factor (2) cannot be used; it is reserved for cases where the injury pre-existed or occurred during service but not directly caused by service, and the service-related failure of clinical management aggravated it. The in Schedule 1 completes the terminology, with definitions for MRCA, VEA, and terminal event as noted. The instrument also imports, via section 11, any other Statement of Principles where a factor refers to an injury or disease covered by another SoP. That cross-referencing ensures consistency across multiple injury categories.

The instrument directly affects veterans, members of the Peacekeeping Forces, and members of the Forces under the VEA, as well as members under the MRCA who have rendered relevant service as defined. This means those who have served in operational service, peacekeeping service, hazardous service, British nuclear test defence service under the VEA, or warlike/non-warlike service under the MRCA. It does not apply to peacetime service under the VEA (i.e., defence service rendered after 7 April 1994 that is not operational), nor to service under the Military Rehabilitation and Compensation Act 2004 that is peacetime service - such claims are governed by different evidentiary standards. The instrument also affects their dependants and legal personal representatives, as a death claim for a terminal event contributed to by electrical injury can arise from the same factors. Indirectly, the instrument affects the Repatriation Commission (the decision-maker), the Veterans' Review Board, and the Administrative Appeals Tribunal, because they are bound by the factor framework when assessing claims. Legal practitioners and advocates advise clients on whether a reasonable hypothesis exists based on the instrument. Medical practitioners providing reports must tailor their evidence to the specified factors: exposure to electrical current at the time of clinical onset, exposure to an electric arc across the affected area, or inability to obtain appropriate clinical management. The instrument creates a binary gateway: if none of the three factors can be established by the evidence, the claim will fail at the threshold, regardless of any plausible alternative causal theory. This concentrates the incentives of claimants and their representatives on locating evidence of exposure at the time of clinical onset, or proving that clinical management was inappropriate and service-related. It also affects the Commonwealth departments that manage service records (Defence, Veterans' Affairs) because the existence of relevant service is a prerequisite; establishing that the factor is related to service may require records of the incident. For example, a veteran who claims electrical injury from a defective appliance on base must show exposure at the time of clinical onset - the instrument does not allow for delayed onset or cumulative exposure unless the clinical onset happens at the moment of exposure. Similarly, factor (2) (inability to obtain appropriate clinical management) only operates in a limited set of circumstances: where the electrical injury was suffered or contracted before or during (but not arising out of) relevant service, and the inability to manage it materially contributed to or aggravated the injury. This restricts the utility of factor (2) for most service-related electrical injuries; it primarily applies when, for instance, a veteran had a pre-existing electrical injury that was worsened because of service-related impediments to treatment (e.g., posting to a remote location without suitable medical facilities). For the broader medical community, the definition of electrical injury is technical and excludes electromagnetic radiation, meaning that injuries from radar, communication equipment, or non-ionising radiation sources are not covered. This has implications for workers in defence communication roles who may claim for non-thermal effects. The instrument also affects the administration of compensation: by standardising the causal factors, it reduces the need for individual medical panels to opine on general causation, but it imposes an additional evidentiary burden on the claimant to prove the factor existed and was service-related.

The instrument does not impose duties on private individuals; it is a rule of evidence for the adjudication of compensation claims under the VEA and MRCA. However, it creates a right for a claimant to have a reasonable hypothesis accepted if at least one of the listed factors exists and is related to relevant service. Conversely, it imposes an evidentiary burden on the claimant to establish the factor on the balance of probabilities (the standard for proving the factual existence of the factor, as opposed to the "reasonable hypothesis" standard for the link to service - see Vokes and similar AAT cases). The right is qualified: the hypothesis must be consistent with the template; it cannot be contradicted by the proved facts. If the decision-maker finds that the hypothesis is not tenable in view of the evidence, the claim may still fail even if a factor exists. The instrument gives the RMA the authority to determine the factors (section 8 declares the view). There is no right to challenge the factors themselves; they are legislative instruments subject to disallowance by Parliament but not reviewable by a court on merits. The duty of the Repatriation Commission is to apply the factors when assessing claims under section 120A. If a claimant establishes a factor, the Commission must then consider whether the hypothesis is reasonable - that is, not fanciful, impossible, or contrary to proved facts. The instrument also creates a right to rely on other Statements of Principles where a factor refers to an injury or disease covered by another SoP (section 11). For instance, if the factor involves "inability to obtain appropriate clinical management" and that management relates to a separate disease (e.g., a secondary infection), the conditions of that other SoP must be satisfied. This cross-referencing can expand or restrict the claim depending on the content of other instruments. The dictionary defines relevant service, which determines eligibility. There is no right for claimants under other types of service (e.g., peacetime service under the MRCA) to use this instrument; they are governed by different provisions. For the Crown, the instrument creates a duty to accept the RMA's determination as binding: the Commission cannot disregard the factors if the evidence supports them. But the Commission retains discretion to assess credibility and weight of evidence regarding whether the factor existed. The instrument is silent on the timeframes for making claims, but the underlying VEA and MRCA contain limitation periods. A practical right for claimants is that once a factor is established, the benefit of the doubt under section 120(1) of the VEA applies: if the hypothesis is reasonable, the claim must be accepted unless the Commission disproves it beyond reasonable doubt (for operational service) or on the balance of probabilities (for other relevant service). So the instrument effectively lowers the evidentiary bar for claimants who can meet its conditions.

This instrument does not create penalties or enforcement mechanisms of its own. It is a legislative instrument that modifies the operation of the VEA and MRCA with respect to claims. The "penalty" for failing to comply with its terms is practical: a claimant who cannot establish any of the three factors will have their claim denied, and will not receive compensation or medical treatment coverage for electrical injury. There is no criminal or civil liability for non-compliance. However, there is an indirect enforcement dimension: the Repatriation Commission, when making decisions, must apply the instrument. If the Commission misapplies the instrument, a claimant can seek review by the Veterans' Review Board (VRB) and then the Administrative Appeals Tribunal (AAT). The AAT has the power to set aside the Commission's decision and substitute its own. The instrument itself cannot be enforced by a court as a right of action; rather, it is a rule that the decision-maker must follow under penalty of jurisdictional error. Any failure to apply the correct factors could give rise to judicial review under the Administrative Decisions (Judicial Review) Act 1977 or section 39B of the Judiciary Act 1903 - but that is a remedy for legal error, not a penalty for contravening the instrument. The instrument also has a self-repealing provision not explicitly stated but implied through the operation of the legislation: Statements of Principles under subsection 196B(2) are generally reviewed and remade every few years. Indeed, the amendment history shows that section 2 (the commencement provision) was repealed by LA s 48D, and section 4 (something else) repealed by LA s 48C. The instrument remains in force until revoked or replaced. From a compliance burden perspective, the instrument imposes no costs on the private sector. The only cost is to the Commonwealth in processing claims and to claimants in gathering evidence. Because the factors are narrow, the instrument may reduce the number of successful claims, thereby reducing public expenditure on compensation. Conversely, for claimants who do establish a factor, the process is streamlined: they do not need to prove general causation beyond the medical-scientific evidence already accepted by the RMA. This is a trade-off: predictability versus restrictiveness.

This instrument operates as a delegated legislative power under subsection 196B(2) of the VEA. It is subordinate to the VEA and the MRCA, and must be applied where sections 120A (VEA) and 338 (MRCA) require. The VEA section 120A(2) provides that a claim for operational service must be determined by the Commission "to its reasonable satisfaction" but subject to the applicable Statement of Principles. Section 120A(3) provides that if the material does not raise a reasonable hypothesis consistent with the SoP, the claim fails. This instrument directly controls that determination. It interacts with the Military Rehabilitation and Compensation Act 2004 through a similar mechanism: section 338 of the MRCA incorporates the SoP regime for warlike and non-warlike service claims. The instrument also interacts with other Statements of Principles via section 11. If a factor in this instrument incidentally involves another injury (e.g., the inability to obtain appropriate clinical management for electrical injury leads to a psychiatric condition), the factor might trigger the psychiatric SoP, and its factors must also be satisfied. This can create layered requirements: a claimant must satisfy both instruments to succeed on the broader claim. The instrument does not interact with state workers' compensation laws (except indirectly through the MRCA's exclusive nature) or with the Safety, Rehabilitation and Compensation (Defence-related Claims) Act 1988 (DRCA). Claims under the DRCA for peacetime service are not governed by this instrument; they use different causation rules. The instrument also interacts with the Social Security Act 1991 and Veterans' Entitlement (Disability Compensation) provisions when compensation offsets are calculated. An accepted claim under this instrument can affect other benefits, such as age pension (though that is a separate process). The definition of "electrical injury" in this instrument may not align with definitions in other Medico-legal contexts, such as workers' compensation schemes that include electromagnetic radiation effects. This could produce inconsistent outcomes for a veteran who has both a VEA claim and a private compensation claim for the same incident - the VEA claim is limited by this instrument, while the private claim may succeed on broader causation. The ICD-10-AM codes referenced are from the Tenth Edition, 2017; if new editions are published, the instrument is not automatically updated - it specifically fixes the code to that edition (subsection 7(3) and (4)). This could create obsolescence if the coding changes for electrical injuries. The instrument does not interact with criminal law; there are no penalties imported from other acts. Finally, the governs the registration and disallowance of this instrument. The amendment history shows sections 2 and 4 were repealed by the provisions (s 48D, s 48C), indicating that the instrument's commencement and other formalities are now governed by that Act.

The original instrument was Statement of Principles concerning electrical injury (Reasonable Hypothesis) (No. 41 of 2018), registered on 30 April 2018 and commencing on 28 May 2018. It was later amended by Amendment Statement of Principles concerning electrical injury (Reasonable Hypothesis) (No. 13 of 2024), registered on 8 January 2024 and commencing on 22 January 2024. The amendment made three changes: (1) subsection 7(2) was amended (see endnote 4 - "am No. 13 of 2024"); (2) subsection 9(1) was amended; and (3) new subsection 9(1A) was added. The precise text of the changes is not provided in the compilation except for the new subsection 9(1A) which reads: "having exposure to an electric arc across the affected area of the body at the time of clinical onset". The original factor (1) was "having exposure to electrical current at the time of clinical onset"; the amendment presumably adjusted this wording, though the compilation shows the current text of 9(1) as that same phrase. It is possible the amendment clarified "exposure" definitions or added "across the affected area" language. The amendment also presumably revised the definition of electrical injury in subsection 7(2) - possibly to include electric arc exposure as part of the injury rather than just a factor. The onus is on the reader to consult the amending instrument for the precise changes. The legislation history notes that section 2 (commencement) and section 4 (something else) were repealed by the Legislation Act 2003 (sections 48D and 48C respectively). These are standard housekeeping repeals: Sections 2 and 4 often contain commencement provisions and definitions that become unnecessary once the instrument is compiled under the Legislation Act 2003 automatic commencement rules (section 48D provides for automatic repeal of commencement provisions after 5 years, and section 48C provides for automatic repeal of certain old provisions). No other amendments have been made. The instrument has been in force for over six years, and its viability depends on ongoing medical-scientific evidence; the RMA may revoke or remake it at any time. The endnote 4 shows only two affected provisions: subsection 7(2) and subsection 9(1) amended, and subsection 9(1A) added. There are no pending uncommenced amendments listed. The amendment history is thin, indicating stability of the factor structure since 2018. The amendment in 2024 appears to have widened the scope slightly by explicitly including electric arc exposure as a separate factor, rather than subsuming it under "exposure to electrical current." This may reflect new medical understanding that electric arcs can cause injury without direct current flow through the body (e.g., flash burns to skin not requiring contact). The amendment also likely refined the definition to ensure "electrical injury" includes arc phenomena. This reduces the risk that claims based solely on arc exposure (without direct current) would fail. From a free-market perspective, this is a modest expansion of the compensable category, likely increasing claim numbers slightly but still within narrow bounds.

The source text does not list any cases. However, as a legislative instrument, the Statement of Principles concerning electrical injury will have been litigated before the Veterans' Review Board and the Administrative Appeals Tribunal, and potentially the Federal Court on questions of law. The instrument is binding on those tribunals, but claimants often challenge whether the factors are satisfied on the facts. Common litigation issues include: whether the exposure was "at the time of clinical onset" - usually requiring contemporaneous symptoms; whether a particular incident fell within "electrical injury" as defined, especially the exclusion of electromagnetic radiation; and whether the inability to obtain appropriate clinical management was related to service. There is no case law cited in the endnotes, so one must infer from general SoP litigation trends. The 2024 amendment adding electric arc exposure likely responded to a tribunal decision where a claim for arc burns without direct current flow was rejected, prompting the RMA to adjust the factors. Alternatively, it may have been proactive based on new medical research. The instrument itself has not been judicially reviewed on its validity, as the RMA's determinations are generally upheld unless they are irrational or not based on sound medical-scientific evidence. The High Court has upheld the SoP scheme in Re Minister for Immigration and Multicultural and Indigenous Affairs; Ex parte Lam (2003) - though that case is about procedural fairness, not directly about SoPs. The Federal Court in Repatriation Commission v Deledio (1998) established the four-step test for reasonable hypothesis, which requires satisfaction of the relevant SoP. Thus, this instrument is tested through that prism. There is no specific litigation history for this electrical injury SoP available from the source. Practitioners would need to search tribunal databases for decisions involving "T75.0" or "electrical injury" and "Statement of Principles." Given the narrow scope, claims are likely infrequent. The most contentious area is likely the exclusion of electromagnetic radiation: a veteran who suffered alleged injuries from exposure to radar or other non-ionising radiation would have difficulty because the instrument explicitly excludes it. There may be AAT cases where such claims failed, prompting advocacy for amendment but none occurred. The litigation history is sparse, which indicates the instrument is relatively uncontroversial but also that its limitations are accepted.

Several traps and nuances arise from this instrument:

1. Definition of electrical injury excludes electromagnetic radiation: This is a significant carve-out (paragraph 7(2)(c)). Veterans with exposure to radar, high-frequency communication equipment, or other sources of non-ionising radiation cannot bring a claim under this SoP, even if they suffer symptoms commonly attributed to electrical exposure. The RMA has determined that the medical-scientific evidence does not support a link, but this is a contested area in other jurisdictions. Claimants must ensure they are not misled by the term "electrical injury" which laypeople might think includes all electric phenomena.

2. "At the time of clinical onset" ambiguity: Factors (1) and (1A) require exposure at the time of clinical onset. This means the symptoms of injury must appear immediately or very shortly after the exposure. Delayed onset electrical injury (e.g., neurological symptoms appearing days later) is not captured unless the clinical onset is contemporaneous. This is a high bar for conditions like peripheral neuropathy from electric shock, where symptoms can be delayed. The instrument effectively denies claims for partial or cumulative exposure without immediate symptoms.

3. Factor (2) limited to material contribution/aggravation: The inability to obtain appropriate clinical management only applies where the electrical injury was suffered or contracted before or during (but did not arise out of) relevant service. If the injury arose out of service (e.g., a workplace electric shock on base), factor (2) is not available. This is counterintuitive: the servicemember who had the primary exposure on duty cannot use factor (2) to argue that poor follow-up care worsened their injury; factor (2) is reserved for those whose injury occurred outside service activities. This restriction is often overlooked.

4. Electric arc exposure vs. electrical current: The 2024 amendment added factor (1A) for electric arc exposure across the affected area. However, the definition of electrical injury in subsection 7(2) includes "electrical flash burns" which are already arc burns. So arguably factor (1A) duplicates what was already covered under factor (1) if "exposure to electrical current" was interpreted broadly. But the amendment suggests that pure arc exposure without direct current flow might not have been covered. The gotcha is that claimants with arc burns should now cite factor (1A) distinctly, or risk the decision-maker ignoring the factor.

Compliance with this instrument is not a matter of regulatory action for businesses; it is about how the Repatriation Commission and tribunals apply it. For claimants and their representatives, the process is:

1. Identify relevant service: Confirm the person rendered one of the six types of relevant service listed in the dictionary. This is a jurisdictional threshold. Obtain service records, particularly posting history and incident reports.

2. Establish the definition of electrical injury: The claimed injury must fall under subsection 7(2). Obtain medical evidence that the injury is physical damage from the flow of electrical current through or across the body, or from an electric arc. Exclude electromagnetic radiation causation. Where possible, use the ICD-10-AM code T75.0 or T75.4, but note that the code is not determinative; the definition controls. If the injury is ambiguous (e.g., burns from a spark but no direct current flow), argue under factor (1A) for electric arc exposure.

3. Prove at least one factor: Gather evidence to satisfy one of the three factors: (1) exposure to electrical current at the time of clinical onset; (1A) exposure to an electric arc across the affected area at the time of clinical onset; or (2) inability to obtain appropriate clinical management for electrical injury (with the important caveat from section 10(2) that this factor only applies if the injury did not arise out of service but was pre-existing or contracted during service not arising out of it). For factors (1) and (1A), evidence must show the exact time of exposure and the immediate onset of injury. Witness statements, incident reports, medical attendances on the day, and specialist opinions stating the clinical onset was contemporaneous are critical. For factor (2), obtain evidence that clinical management was inappropriate (e.g., delayed treatment, lack of specialist care) and that this was related to service (e.g., posting to a location without proper medical facilities, or service-related barriers to attending appointments). The claimant must also show that the electrical injury itself was not a consequence of service (i.e., it arose before service or during service but from a non-service cause like a civilian accident).

4. Relate the factor to relevant service: Under section 10(1), the factor must be related to the relevant service. This requires a causal connection, not merely a temporal one. For exposure factors, the incident must occur during the performance of service duties or while on a service base. A lightning strike while the veteran was on leave at the beach would not be related. For clinical management factor, the inability must be due to service circumstances. The Commissioner will apply the "reasonable hypothesis" standard: the hypothesis must be consistent with the template and not contrary to proved facts. The claimant should present a plausible narrative linking the factor to service.
