Statement of Principles concerning posttraumatic stress disorder (Balance of Probabilities) (No. 98 of 2022)

This instrument is a Repatriation Medical Authority Statement of Principles (SOP) titled Statement of Principles concerning posttraumatic stress disorder (Balance of Probabilities) (No. 98 of 2022). It is made under subsection 196B(3) of the Veterans' Entitlements Act 1986 (VEA) (see section 3) and commences on 21 November 2022 (section 2). The SOP replaces the earlier Statement No. 83 of 2014 (section 4). It applies to claims “to which section 120B of the VEA or section 339 of the Military Rehabilitation and Compensation Act 2004 (MRCA) applies” (section 5). The instrument contains a DSM‑5‑TR‑derived diagnostic definition of posttraumatic stress disorder (PTSD) (section 7(2)), a definition of death from PTSD (section 7(5)), a statement of the RMA’s evidential view (section 8), an enumerated list of factors that must exist for a causal connection on the balance of probabilities (section 9), rules about how those factors relate to relevant service (section 10), and a cross‑reference rule to other SOPs (section 11). The Schedule 1 dictionary supplies key technical definitions used throughout.

Mechanically the SOP does two things. First, it fixes the clinical meaning of “posttraumatic stress disorder” for the purposes of claims governed by the VEA/MRCA by reproducing DSM‑5‑TR criteria as the instrument’s definition (section 7(2); Schedule 1 defines DSM‑5‑TR). Second, and materially for decision‑making, it identifies the specific exposure/timing/clinical factors which, if established and shown to be related to a person’s relevant service, suffice to establish on the balance of probabilities that PTSD (or death from PTSD) is connected with that service (sections 8-10). The SOP therefore functions as the RMA’s medical causation template to be applied in adjudicating eligible claims under the VEA and MRCA.

The SOP does not itself set entitlement amounts, administrative procedures for claiming, or penalties; it is a technical medical instrument intended to be applied where claim provisions of the VEA or MRCA are engaged (section 5). The RMA characterises the medical evidence as supporting the view “that it is more probable than not” that PTSD and death from PTSD can be related to relevant service (section 8). The SOP prescribes the minimum factual/medical elements (section 9) and the relationship rules to service (section 10) that decision‑makers should apply when deciding causation questions under the designated claim provisions.

The SOP organises its medical and causal logic around several core concepts: the DSM‑5‑TR diagnostic criteria for PTSD; a closed list of qualifying stressors grouped into category 1A and category 1B; thresholds for repeated or extreme aversive exposure; temporal windows tied to clinical onset or clinical worsening; and a rule that the enumerated factors must be “related to the relevant service” (sections 7-10). These concepts are defined and cross‑referenced in Schedule 1.

Diagnostic concept: PTSD is defined in subsection 7(2) using language taken from DSM‑5‑TR, reproduced within the instrument. The definition contains the full cluster structure: exposure criterion, intrusion symptoms (Criterion B), avoidance (Criterion C), negative alterations in cognition and mood (Criterion D), alterations in arousal and reactivity (Criterion E), duration >1 month (Criterion F), clinically significant distress/impairment (Criterion G), and exclusion for substance or another medical condition (Criterion H). The SOP explicitly states that, while PTSD attracts ICD‑10‑AM code F43.1, the applied meaning is the DSM‑5‑TR‑derived definition (sections 7(2)-(3); 7(4) explains the ICD‑10‑AM cross‑reference).

Exposure categories: The SOP distinguishes severe traumatic events into category 1A stressors and category 1B stressors (Schedule 1). Category 1A includes life‑threatening events, serious physical attack/assault (including sexual offences), and threats with weapon, captivity, kidnapping or torture. Category 1B covers killing/maiming another person, eyewitnessing killing or critical injury, witnessing atrocities, clearing corpses/critically injured casualties, or viewing a corpse/critically injured casualty as an eyewitness (Schedule 1 definitions).

Aversive detail/occupational exposure: “Being exposed to repeated or extreme aversive details of severe traumatic events” is defined to include frontline work such as first responders collecting human remains, police repeatedly exposed to child abuse details, drone operators viewing planned strikes, or repeatedly listening to detailed personal accounts. The definition expressly includes media exposure only where viewing the images is a work requirement (Schedule 1).

Timing and temporal windows: Section 9 requires that at least one of the enumerated factors exist before the clinical onset of PTSD (items 1-6) or before clinical worsening (items 7-12), with specific temporal windows for some items: having a significant other experience a category 1A stressor within 1 year before clinical onset/worsening (items 3 and 9), and experiencing the traumatic death of a significant other within 2 years before onset/worsening (items 4 and 10). The duration criterion in the DSM‑derived definition requires disturbance duration of more than one month (section 7(2)F).

This SOP directly impacts claimants and decision‑makers in the VEA and MRCA administrative systems. By section 5, the SOP “applies to a claim to which section 120B of the VEA or section 339 of the MRCA applies.” That means veterans, eligible former members of the Defence Forces and serving members who lodge claims invoking those provisions are affected because this SOP supplies the medical causation criteria used in adjudicating whether PTSD or death from PTSD is connected with relevant service.

Claimant population. The instrument addresses persons who can establish the DSM‑5‑TR criteria for PTSD and who also can demonstrate at least one of the factors listed in section 9 related to their relevant service (section 9 and section 10(1)). Relevant service is defined in Schedule 1 to include 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. The scope therefore covers a wide range of veterans and members, including those whose exposures occurred in non‑combat and peacetime contexts where the MRCA applies.

Decision‑makers and medical advisors. The RMA is the instrument‑maker (section 3). The SOP is intended to be used by authorities deciding claims under the VEA and MRCA. While the instrument does not name specific adjudicating agencies, its application clause (section 5) makes it clear that decision‑makers responsible for applying sections 120B VEA and 339 MRCA will use this SOP to determine causal connection. Medical assessors who apply diagnostic criteria must follow the DSM‑5‑TR‑derived definition in section 7(2) as reproduced in the SOP; Schedule 1 defines DSM‑5‑TR as the 2022 text revision.

Third parties and evidence providers. The SOP’s focus on specific exposure categories and temporal windows makes military records, unit reports, operational logs, witness statements, medical records, and civilian employment records (if exposure occurred in a work role that involved viewing media imagery as a work requirement) directly relevant. For example, a drone operator’s operational logs showing viewing of planned strikes are a factual node that corresponds to the Schedule 1 example of aversive exposure. The definition of “significant other” is broad and includes close family or close personal relationships, so evidence regarding the experiences or death of such persons within the temporal windows (1 year or 2 years) will be material.

Legal actors. Practising lawyers and advocates preparing claims must align submissions with the SOP’s enumerated factors and definitions. The SOP affects the construction of evidentiary strategies: establish DSM‑5‑TR diagnostic features (section 7(2)); show the timing of clinical onset or clinical worsening; demonstrate an applicable section 9 factor and, critically, show that the factor is related to relevant service per section 10(1). Where a factor refers to another SOP’s injury or disease, section 11 requires application of that other SOP, meaning counsel must track cross‑references among SOPs.

This SOP establishes normative medical criteria that interact with statutory duties and rights under the VEA and MRCA, but the instrument itself does not create independent administrative duties or entitlements beyond defining diagnostic and causal standards. The principal legal duties and rights to bear in mind are allocated as follows.

Duty to apply the SOP in relevant claims. Section 5 makes the SOP applicable to claims falling under section 120B of the VEA or section 339 of the MRCA. Administrative decision‑makers responsible for those claims have the duty to apply the medical causation framework set out here when assessing whether PTSD or death from PTSD is connected with relevant service. The instrument is made under subsection 196B(3) of the VEA (section 3), which empowers the Repatriation Medical Authority to determine Statements of Principles; the duty to have regard to this RMA instrument in adjudication is implicit in the statute’s architecture.

Duty to establish relation to relevant service. Even where a claimant can establish one of the section 9 factors, subsection 10(1) requires that “the existence in a person of any factor referred to in section 9, must be related to the relevant service rendered by the person.” That is a substantive connection requirement that decision‑makers must test,factual linkages between the exposure event and the person’s service record are necessary.

Differential rule for pre‑existing PTSD. Subsection 10(2) imposes a narrower application for the factors in subsections 9(7)-9(13): they “apply only to material contribution to, or aggravation of, posttraumatic stress disorder where the person's posttraumatic stress disorder was suffered or contracted before or during (but did not arise out of) the person's relevant service.” That creates a duty on decision‑makers to distinguish between service that “arose out of” and service that only contributed or aggravated pre‑existing PTSD, and to apply the appropriate subset of factors accordingly.

Rights to use other SOPs where relevant. Section 11 gives rights‑bearing effect to other SOPs: if a factor in section 9 refers to an injury or disease covered by another SOP made under s196B(3), then that other SOP’s factors apply “in accordance with the terms of that Statement of Principles as in force from time to time.” Decision‑makers and claimants must therefore know the current text of those other SOPs; there is a duty to cross‑apply relevant instruments.

Medical diagnostic right/obligation. The SOP prescribes the DSM‑5‑TR structure for diagnosing PTSD for the purposes of these claims (section 7(2) and Schedule 1). Medical practitioners and assessors preparing reports for claims must use (or map to) the DSM‑5‑TR criteria set out in the SOP when offering opinions on whether the person meets the required diagnostic threshold.

The Statement of Principles is a technical medical instrument and does not itself create criminal penalties, civil fines, or enforcement mechanisms. The instrument contains no express sanctions, administrative penalty provisions, or enforcement procedures. Its legal effect operates through its prescribed use in adjudicating claims under the VEA and MRCA (section 5), not by creating independent enforcement powers.

Operational enforcement and application. Enforcement in the sense of effecting outcomes (acceptance or rejection of claims, conferral of entitlements, or denial of benefits) will occur through the administrative processes and decision‑making provisions set out in the VEA and MRCA to which the SOP applies. For example, when decision‑makers apply the SOP’s factors and DSM‑5‑TR diagnosis to a claimant’s file, the SOP informs whether a claimant meets the statutory causation tests that trigger entitlement under those statutes. The SOP does not itself specify which administrative body takes the final decision or the remedies available for adverse decisions; those procedural arrangements are in the VEA/MRCA.

No criminal or civil enforcement language. The instrument contains no sections that create offences, pecuniary penalties, compliance notices, or authorised officer powers. There is no provision for injunctive relief, enforcement orders, or statutory fines within the SOP text supplied. Any compliance failures or disputes about the application of the SOP will be resolved through existing administrative review and judicial review mechanisms inherent in the VEA and MRCA frameworks, but the SOP itself does not stipulate those mechanisms.

Monitoring and application risk. The RMA’s statement in section 8 that on the available medical‑scientific evidence it is more probable than not that PTSD and death from PTSD can be related to relevant service is a policy/evidentiary pronouncement rather than an enforcement mechanism. The practical “enforcement” of that view depends on the administrative bodies, medical assessors, and courts giving effect to the SOP in claim determinations. Implementation risk includes inconsistent application by decision‑makers, divergent medical opinion, or jurisprudential challenge, but the SOP contains no enforcement instruments to correct or sanction misapplication.

Cross‑instrument consequences. Section 11’s rule that factors referring to another SOP must be dealt with according to that other SOP can produce consequential enforcement outcomes: incorrect identification of the applicable SOP could lead to misapplication and consequent acceptance/denial of entitlements. Again, the remedy for misapplication is procedural review under the governing statutes rather than a sanction contained in the SOP.

The instrument is expressly made under subsection 196B(3) of the Veterans' Entitlements Act 1986 (section 3) and is designed to be applied in the adjudication of claims governed by the VEA and the Military Rehabilitation and Compensation Act 2004 (MRCA) (section 5). Its primary interaction is therefore with the statutory causation and entitlement frameworks of those Acts.

Application to VEA and MRCA claims. Section 5 makes the SOP applicable to claims to which section 120B of the VEA or section 339 of the MRCA applies. That locates the SOP functionally within the statutory causation regime: the SOP supplies the medical criteria and list of factors that adjudicators should use when determining causation issues under those sections. The SOP does not itself replace or amend the VEA or MRCA, nor does it specify the benefits, entitlements, or procedural avenues contained in those Acts; it operates as an evidentiary instrument referenced by them.

Relationship with other Statements of Principles. Section 11 sets a cross‑instrument rule: where a factor in section 9 refers to an injury or disease covered by another SOP made under subsection 196B(3) of the VEA, “the factors in that Statement of Principles apply in accordance with the terms of that Statement of Principles as in force from time to time.” Practically, that means adjudicators must cross‑check whether the factual or medical factor being invoked is already covered by a different SOP and then apply that SOP’s factors. The cross‑reference rule imports the contemporaneous text of other SOPs, so changes to those SOPs will affect application. That mechanism creates an inter‑SOP dependency structure that requires decision‑makers to maintain current versions of multiple SOPs.

DSM/ICD interaction. Section 7(2) adopts DSM‑5‑TR criteria for PTSD. Section 7(3) and (4) note that PTSD attracts ICD‑10‑AM code F43.1 but that for application of this SOP the meaning is as given in subsection 7(2) (DSM‑5‑TR). This expresses a clear hierarchy: diagnostic meaning is DSM‑5‑TR‑based even where ICD coding applies elsewhere. Decision‑makers and medical assessors must therefore map clinical documentation to the DSM‑5‑TR terms reproduced in the SOP, not merely to ICD‑10‑AM coding.

Evidence standards vis‑à‑vis other legislation. The SOP is explicit that the standard of proof is balance of probabilities: the RMA’s view in section 8 is that “on the sound medical‑scientific evidence available” it is more probable than not that PTSD and death from PTSD can be related to relevant service, and section 9 frames the factors as what “must exist before it can be said that, on the balance of probabilities” a connection is made. That aligns with the civil standard used in administrative determinations under the VEA and MRCA. Any interaction with laws employing different standards of proof would require careful mapping; the SOP itself does not purport to alter standards in other statutes.

This instrument records one immediate amendment action: repeal of the prior PTSD Statement of Principles No. 83 of 2014. Section 4 states: “The Statement of Principles concerning posttraumatic stress disorder No. 83 of 2014 … is repealed.” The instrument itself is dated 21 October 2022 (cover text) and commences on 21 November 2022 (section 2), so the current SOP took effect on that commencement date and replaced the 2014 instrument from that date.

No other amendments, schedules of prior amendments, or transitional provisions are set out in the text provided. The SOP is self‑standing and incorporates the DSM‑5‑TR definition (Schedule 1) and a suite of definitions that differ in detail from earlier versions; for example, the DSM‑5‑TR reference is explicitly to the 2022 Text Revision (Schedule 1). Because section 11 permits factors to be linked to other SOPs “as in force from time to time,” the instrument contemplates future amendment activity in other SOPs affecting its application, but it contains no mechanism within its own text for staged transition or retrospective application beyond the repeal of the 2014 SOP.

Administrative provenance. The instrument indicates it was executed under the authority of the Repatriation Medical Authority with the Common Seal affixed at the direction of the Chairperson (cover page), and section 3 records the statutory power used (subsection 196B(3) of the VEA). The instrument therefore follows the RMA’s standard administrative practice for issuing SOPs under the VEA and its amendments.

Practical consequence of repeal. Where cases or claims were assessed under the 2014 SOP prior to 21 November 2022, the 2014 instrument governed those determinations at that time. From the commencement date, the 2022 SOP governs new applications and ongoing claims to which the cited sections of the VEA and MRCA apply, subject to any transitional rules in the VEA/MRCA or departmental practice which are not contained within this text. Because no explicit transitional arrangements are included here, practitioners should assume the new SOP applies to claims within the statute’s operation from the commencement date unless the parent Acts or relevant administrative directions state otherwise.

No recorded later amendments. The instrument text provided contains no subsequent amendment history, schedules, or addenda. Users must check the official consolidated FROl or RMA publications for any later modifications to this SOP or to any SOPs cross‑referenced under section 11.

The text supplied contains no judicial decisions, case summaries, or references to litigation concerning this SOP. The instrument does not name or summarise any cases; it is a standalone RMA determination. There is no litigation history recorded in the body of the instrument, and no footnotes or notes cite any tribunal or court decisions.

Implications for litigators. The absence of litigation history in the instrument means that, as of the instrument text, there are no judicially settled points provided within the SOP itself to guide interpretation. Practitioners should therefore expect that interpretation issues arising from the SOP’s definitions and factor lists (for example, the meaning of “clinical onset”, the threshold for “severe childhood abuse”, the scope of “being exposed to repeated or extreme aversive details” in modern operational contexts, or the application of subsection 10(2)) may be litigated and that persuasive authority will develop in administrative tribunals and courts over time. However, that future litigation is outside the instrument’s text.

Common dispute nodes likely to generate litigation. While not recorded in this SOP, particular aspects of the instrument are predictable flashpoints for dispute and thus likely future litigation (these are observations about likely areas of contest rather than reports of existing cases): the temporal relation tests required by section 9 (timing of factor relative to clinical onset or worsening); the “related to the relevant service” requirement in subsection 10(1); the boundaries of “being exposed to repeated or extreme aversive details” (and whether certain media exposure qualifies absent a work requirement); the interpretation of “severe childhood abuse” (for example, threshold of “serious” harm and identity of perpetrator); the scope of the corpse definition (explicitly excludes closed body bags and open‑casket viewing); and the application of section 11 when factors invoke other SOPs. Any of these issues could give rise to contested administrative decisions and judicial review or merits review proceedings under the VEA/MRCA.

Need for external research. Because the instrument does not contain litigation references, legal teams preparing to litigate or advise on claims based on this SOP must compile precedents from the relevant administrative tribunal and court databases after the commencement date. They must track how decision‑makers apply DSM‑5‑TR diagnostic language to Australian administrative processes and how courts treat the SOP’s cross‑referencing rules and timing windows.

In summary, the instrument contains no litigation history within its text. The potential for litigation is inherent in several interpretive points, but existing case law is not provided here and must be sourced externally by practitioners.

This SOP contains multiple technical features and definitional choices that can materially affect claim outcomes. The following are concrete items to watch for; each point references the relevant provision in the instrument.

1. DSM‑5‑TR as the controlling diagnostic text. Section 7(2) reproduces DSM‑5‑TR criteria and Schedule 1 defines DSM‑5‑TR as the 2022 Text Revision. Decision‑makers must therefore map clinical records to DSM‑5‑TR language. If a practitioner submits evidence based on an older DSM edition or solely on ICD‑10‑AM coding, that mismatch can create evidentiary friction. Section 7(3) explicitly says that despite ICD‑10‑AM code F43.1 being associated with PTSD, the applied meaning is the DSM‑5‑TR definition in subsection 7(2).

2. The balance of probabilities standard and the RMA’s evidential posture. Section 8 states the RMA’s view that, on the medical‑scientific evidence, it is more probable than not there is a connection between PTSD and relevant service in appropriate cases. But section 9 frames the requirement that “at least one” of the enumerated factors must exist before causation can be said to be established on the balance of probabilities. Practically, this means claimants must prove a listed factor and relation to service on the civil standard; medical opinion alone will not substitute for the enumerated factor.

3. Narrow temporal windows. Several factors require specified windows,for example, a significant other’s category 1A stressor must occur within 1 year before clinical onset/worsening (items 3 and 9 of section 9), and traumatic death of a significant other within 2 years (items 4 and 10). Claims relying on delayed onset beyond those windows may not satisfy the SOP even if the causal connection is plausible.

4. “Related to the relevant service” requirement. Subsection 10(1) requires that any factor in section 9 be “related to the relevant service rendered by the person.” This is a substantive nexus test independent of the existence of the factor. Practitioners must establish how a particular stressor in a person’s life connects to their service record.

5. Distinct treatment of pre‑existing PTSD. Subsection 10(2) confines subsections 9(7)-9(13) to material contribution or aggravation of PTSD that was “suffered or contracted before or during (but did not arise out of) the person's relevant service.” That distinction is delicate: a claimant whose PTSD arose out of service cannot rely on those factors for contribution or aggravation; conversely, those factors apply only in the narrower context of pre‑existing or concurrent non‑service‑arising PTSD.

For claimants, clinicians, advocates and decision‑makers, compliance with this SOP is primarily evidentiary and interpretive: align diagnosis and causal evidence with the SOP’s specific definitions, factors, and temporal rules. Practical steps follow, grounded in the instrument’s text.

1. Use DSM‑5‑TR language in clinical reports. The SOP makes DSM‑5‑TR the controlling diagnostic set (section 7(2); Schedule 1). Clinicians preparing assessments should explicitly diagnose PTSD against the DSM‑5‑TR criteria reproduced in subsection 7(2): document exposure criterion, intrusion symptoms (B), avoidance (C), negative alterations (D), alterations in arousal and reactivity (E), duration >1 month (F), functional impairment (G), and exclusion (H). Explicit mapping of the patient’s symptoms to DSM‑5‑TR items removes ambiguity at adjudication.

2. Establish one or more section 9 factors with precise temporal evidence. Section 9 lists 13 discrete factors. A compliant claim must show at least one such factor “before the clinical onset” (items 1-6) or “before the clinical worsening” (items 7-12) as relevant. For each invoked factor, provide documentary or witness evidence tying the event to the claimant (for example: service records confirming presence at an event; witness statements for eyewitness exposure; operational logs for drone viewing; coroner reports for traumatic death of a significant other). Where a factor invokes the experiences of a “significant other”, produce evidence showing the relationship and the timing of the other person’s stressor or death relative to clinical onset/worsening (items 3-4 and 9-10).

3. Demonstrate relation to relevant service. Subsection 10(1) requires the factor be “related to the relevant service rendered by the person.” To comply, produce service records, unit deployment reports, duty rosters, mission orders or employer directives that show the stressor occurred in the course of relevant service (see Schedule 1 definition of “relevant service”). If the stressor occurred outside service but close in time, medical opinion linking onset/worsening to service events will be necessary.

4. For pre‑existing PTSD, follow subsection 10(2). If the claimant had PTSD before or during service that did not “arise out of” service, subsections 9(7)-9(13) can be used only to prove material contribution or aggravation. Provide baseline medical records documenting pre‑service PTSD, then document the aggravating exposure during service with timing and objective evidence.
