Statement of Principles concerning moderate to severe traumatic brain injury (Reasonable Hypothesis) (No. 94 of 2018)

This instrument is a Statement of Principles (SoP) determined by the Repatriation Medical Authority (RMA) about moderate to severe traumatic brain injury (TBI) and death from such injury. It is made under subsection 196B(2) of the Veterans’ Entitlements Act 1986 (the VEA) and commences on 26 November 2018 (see sections 2 and 3). The instrument repeals the prior Statement of Principles concerning moderate to severe traumatic brain injury No. 62 of 2012 (section 4). It is expressly made to be applied in claims to which section 120A of the VEA or section 338 of the Military Rehabilitation and Compensation Act 2004 (MRCA) applies (section 5).

Mechanically, the SoP does three things. First, it specifies the medical definition of the condition for the purposes of claims: “moderate to severe traumatic brain injury” is defined by objective clinical thresholds and exclusions (section 7(2)). Second, it sets the evidentiary factors that must be present, as a minimum, to raise a reasonable hypothesis that the condition is connected with relevant service; at least one of two enumerated factors must exist (section 9). Third, it sets the relationship test to relevant service: any factor relied on must be related to the person’s relevant service, and the “inability to obtain appropriate clinical management” factor (section 9(2)) has a limited temporal application where the TBI was suffered or contracted before or during, but did not arise out of, relevant service (section 10).

The SoP is declaratory, not penal. It expresses the RMA’s view that there is “sound medical‑scientific evidence” indicating a connection may exist between moderate to severe TBI and relevant service (section 8). The instrument also cross‑references other SoPs where brain trauma can lead to different diagnosed diseases; it thus sets out how overlapping disease SoPs interact (section 7(2) note; section 11). The Schedule (Schedule 1) supplies definitions of key terms used throughout, including “specified event”, “relevant service” and “terminal event”.

In short, the instrument defines the medical condition at particular clinical thresholds, prescribes the minimal factual/clinical factors that must be shown to raise a reasonable hypothesis of service connection for claims under the VEA or MRCA, limits one of those factors to particular temporal circumstances, and requires that the factors be related to the person’s relevant service. It does not create offences, monetary liabilities or administrative penalties within its text; it operates as an RMA SoP to be applied in the statutory claim processes referenced.

The instrument is structured around a small set of tightly defined legal-medical concepts. The principal concepts, and where they appear, are:

• Moderate to severe traumatic brain injury: Defined in section 7(2). The definition is clinical: damage to the brain resulting from transfer of kinetic energy from external physical forces, manifested by at least one of five objective criteria , loss of consciousness for more than 30 minutes (section 7(2)(a)(i)), anterograde amnesia longer than 24 hours (7(2)(a)(ii)), an intracranial lesion including an abnormality attributable to the injury seen on conventional MRI or CT (7(2)(a)(iii)), penetration of the dura mater (7(2)(a)(iv)), or a Glasgow Coma Scale (GCS) score of less than 13 (7(2)(a)(v)). The definition expressly excludes injury from radiation, electricity, heat and surgery (7(2)(b)).

• Death from moderate to severe TBI: The SoP treats death that is “from” the TBI to include death from a terminal event or condition that was contributed to by the person’s moderate to severe TBI. “Terminal event” is defined in the Schedule to include pneumonia, respiratory failure, cardiac arrest, circulatory failure or cessation of brain function (section 7(3) and Schedule 1).

• Specified event: A defined triggering occurrence that, if experienced at the time of clinical onset, can raise the reasonable hypothesis. The Schedule defines specified events to include the head being struck by an object, the head striking an object, acceleration/deceleration movement without direct external head trauma, a foreign body penetrating the brain, or an explosion or explosive blast (Schedule 1).

• Relevant service: The SoP applies only where a person rendered “relevant service”, a defined term in the Schedule referencing various service categories under the VEA and MRCA: operational service, peacekeeping, hazardous service, British nuclear test defence service (all under the VEA), and warlike or non‑warlike service under the MRCA (Schedule 1).

• Factors that must exist for reasonable hypothesis: Section 9 sets the evidentiary minima. At least one of the following must be present: (1) experiencing a specified event at the time of clinical onset (9(1)); or (2) inability to obtain appropriate clinical management for moderate to severe TBI (9(2)). The instrument requires that any such factor be related to the person’s relevant service (section 10(1)).

• Interaction with other SoPs: The instrument recognises that trauma to the brain can cause other diseases or injuries and lists examples in a Note to section 7(2). Section 11 provides that if a factor in this SoP refers to an injury or disease covered by another SoP determined under subsection 196B(2) of the VEA, then the factors in that other SoP apply in accordance with its terms.

The explicit statutory reach of the instrument is narrow and defined by reference to the claims processes under the VEA and the MRCA. Section 5 states the instrument “applies to a claim to which section 120A of the VEA or section 338 of the Military Rehabilitation and Compensation Act 2004 applies.” Those cross-references mean, operationally, that the instrument will affect:

• veterans and former members (and those qualifying under the MRCA and VEA regimes) who lodge claims where moderate to severe traumatic brain injury or death from such injury is alleged to be connected to their relevant service (section 5 and Schedule 1 definition of “relevant service”).

• decision-makers within the Department and the statutory decision processes who must apply RMA SoPs when assessing whether a reasonable hypothesis exists linking the condition to service. The instrument is made under subsection 196B(2) of the VEA (section 3), the provision authorising the RMA to determine SoPs to be applied in claims.

The Schedule’s definition of “relevant service” identifies operational service, peacekeeping, hazardous service and British nuclear test defence service under the VEA, and warlike and non‑warlike service under the MRCA. Therefore the SoP affects claimants whose qualifying service falls within any of those categories (Schedule 1). The SoP also reaches dependants and estates where the claim concerns death from moderate to severe TBI, because the instrument expressly includes death from a terminal event or condition that was contributed to by the TBI (section 7(3)).

Two groups whose position is clarified by the instrument’s text are:

• Claimants relying on an inability to obtain appropriate clinical management: section 9(2) is limited to material contribution to, or aggravation of, moderate to severe TBI where the person’s TBI was suffered or contracted before or during (but did not arise out of) the person’s relevant service (section 10(2)). That limits the class of claimants who can rely on health‑system access issues to those with pre‑existing TBIs that were present prior to or during service but not caused by the service.

• Persons with brain trauma that has led to other diagnosed diseases: the instrument signals that many other SoPs cover conditions that may arise from brain trauma (note to section 7(2)). Those persons may be required to engage the separate SoPs for those specific diseases when making claims.

The instrument does not purport to create new entitlements; it supplies medically‑framed predicates to be used in existing claims processes. It neither creates new administrative actors nor removes existing ones; the RMA’s role is to issue the SoP (section 3), and the SoP is then applied in claims under the VEA and MRCA frameworks (section 5).

The SoP does not set out statutory duties, fees or criminal offences. Instead it prescribes the minimum factual and clinical factors that must be present to raise a reasonable hypothesis connecting moderate to severe TBI (or death from such TBI) to relevant service. The practical legal effect is to shape evidentiary obligations and the scope of decision-maker inquiry in claims under the VEA and MRCA.

Key legal-functional points in the instrument that translate to duties or evidentiary requirements are:

• Minimum factor requirement: Section 9 requires that at least one of the two enumerated factors must exist before a reasonable hypothesis can be said to be raised. That is an evidential threshold that claimants must meet. Those factors are: experiencing a specified event at the time of clinical onset (9(1)); or inability to obtain appropriate clinical management for the TBI (9(2)).

• Relation to relevant service: Section 10(1) mandates that a factor relied on under section 9 must be related to the person’s relevant service. That imposes a legal requirement that the causal or circumstantial fact relied upon be linked temporally and causally to the relevant service as defined in the Schedule.

• Temporal limitation on inability to obtain appropriate clinical management: Section 10(2) restricts reliance on the inability-to-treat factor (9(2)) to those cases where the TBI was suffered or contracted before or during, but did not arise out of, the person’s relevant service. In other words, inability to obtain appropriate clinical management is available only to claimants with pre-existing or contemporaneous but non-service-origin TBIs, and then only for material contribution or aggravation.

• Cross-application of other SoPs: Section 11 provides that where a factor in this SoP refers to an injury or disease covered by another SoP determined under subsection 196B(2) 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.” That imposes an expectation that decision-makers and claimants must combine relevant SoPs when the factor invoked references other injuries/diseases, and that those SoPs govern their own applicable factors.

• Clinical thresholds set evidentiary content: The definition of moderate to severe TBI in section 7(2) is not open-ended. It requires at least one of explicit clinical criteria (LOC > 30 minutes; anterograde amnesia > 24 hours; intracranial lesion/structural imaging abnormality; penetration of the dura mater; GCS < 13). Those criteria supply the clinical evidentiary content that decision-makers will expect to be demonstrated when assessing claims.

The instrument contains no provisions establishing criminal penalties, civil fines, administrative sanctions, or direct enforcement mechanisms. Its operative function is declaratory and evidentiary: it sets the RMA’s medical-scientific view and the minimum factors to be applied by decision-makers when determining whether a reasonable hypothesis has been raised connecting moderate to severe TBI, or death from it, with relevant service (sections 3, 8 and 9).

Enforcement, in the sense of application, occurs through the claims processes under the VEA and MRCA. Section 5 expressly states the SoP “applies to a claim to which section 120A of the VEA or section 338 of the Military Rehabilitation and Compensation Act 2004 applies.” Therefore the instrument’s legal “teeth” are exercised by administrative officers and decision-makers deciding entitlement claims under those statutes, who must apply RMA SoPs in making findings. The instrument does not include procedural enforcement language,no notice or compliance directions,so its effect is to guide adjudication rather than to impose independent sanctions.

Because the SoP defines clinical thresholds and the factors that must exist, the primary enforcement effect is evidential: claimants who cannot demonstrate at least one of the factors in section 9 or cannot establish that the factor relates to relevant service under section 10 will not have a reasonable hypothesis raised for purposes of the claim. The instrument also specifies that where a factor refers to an injury or disease covered by another SoP, the factors in that other SoP apply (section 11). That places an operational requirement on decision-makers to cross-apply and enforce the terms of multiple SoPs where relevant.

In short: there are no criminal or civil penalties in the instrument. The instrument is enforced through its application to claims under the VEA and MRCA, influencing entitlement and benefit determinations by shaping the legal-medical predicates required to advance a claim.

The instrument is explicitly tied to two statutory claim frameworks. Section 3 records that the instrument is made under subsection 196B(2) of the VEA; section 5 states it applies to claims to which section 120A of the VEA or section 338 of the MRCA applies. Those cross-references make the SoP an implementing medical opinion that feeds into the VEA and MRCA claim determination regimes.

The Schedule’s definition of “relevant service” anchors the instrument in the service categories recognised by the VEA and MRCA. It lists operational service, peacekeeping service, hazardous service and British nuclear test defence service under the VEA, and warlike or non‑warlike service under the MRCA (Schedule 1). The SoP therefore applies only where the claimant’s factual situation brings the claim within those statutory categories.

The instrument also establishes interaction with other RMA SoPs. The Note to section 7(2) states that trauma to the brain can cause other diseases or injuries and identifies a non‑exhaustive list of other SoPs in which brain trauma is listed as a risk factor (for example, epilepsy, cerebrovascular accident, Parkinson’s disease and parkinsonism, dementia pugilistica, subdural haematoma, and suicide and attempted suicide). Section 11 formalises the cross-SoP interaction: if a factor in this SoP refers to an injury or disease covered by another SoP determined under subsection 196B(2) of the VEA, then the factors in that other SoP apply according to its terms.

Mechanically, that means decision-makers applying this SoP must:

• Apply the clinical thresholds and factors in this SoP when the claim asserts moderate to severe TBI as the primary condition (section 7 and 9).

• Identify when a fact relied upon is itself the subject of another SoP (for example, if the factor refers to epilepsy or the sequelae of TBI), and then apply the other SoP’s factors in combination as required by section 11.

The instrument also repeals an earlier SoP (No. 62 of 2012) by section 4. That repeal is a direct legal interaction with the earlier instrument; the new SoP replaces the 2012 version for the purposes of the relevant statutory claims.

The SoP is silent about interaction with State or other Commonwealth laws outside the VEA and MRCA. It does not address issues such as workers’ compensation, general tort litigation, or social security entitlements. Its legal role is bounded: it is a statutory SoP made under a specified VEA power and to be applied in the statutory claim contexts cited.

The instrument contains limited explicit amendment history within its own text. It records a commencement date of 26 November 2018 (section 2). It also expressly repeals the previous Statement of Principles concerning moderate to severe traumatic brain injury No. 62 of 2012, referring to the Federal Register of Legislation number for that earlier instrument (section 4). Beyond that, the instrument does not include historical notes, transitional provisions, or a schedule of prior amendments.

What can be drawn from the instrument is therefore narrow and documentary: as of the date given on the instrument (signed 26 October 2018 and commencing 26 November 2018), the RMA replaced the 2012 SoP with this 2018 instrument (sections 1, 2 and 4). The Schedule confirms definitions used within the instrument and those definitions may reflect updating of terms such as “relevant service” and “specified event” relative to prior versions, but the instrument itself does not provide a textual comparison or annotation describing changes from the 2012 instrument.

For users needing to trace change over time, the one explicit amendment event in the instrument is the repeal of SoP No. 62 of 2012 (section 4). Any other amendments, subsequent replacements, or modifications after commencement are not recorded in the text provided. The instrument does not include savings or transitional clauses for claims in progress at commencement; it simply states that it applies to claims to which the specified provisions of the VEA or MRCA apply (section 5). Practically, that means one must consult the VEA/MRCA claims processes and the timing rules those Acts contain if transitional or retrospective treatment is material, but the instrument itself does not set those transitional rules.

In short, the instrument’s own amendment history within the text is limited to its commencement and the repeal of the 2012 SoP; no other amendments or historical layering are provided in the document supplied.

The instrument as supplied contains no information about litigation, case law, judicial consideration, or administrative appeals that interpret or test its terms. It is the RMA’s determination under subsection 196B(2) of the VEA and is intended to be applied within the statutory claims processes established by the VEA and the MRCA (section 5). The text itself does not record any decisions or disputes that have arisen over its content or application.

Because the instrument is designed to be applied in claims under statutory schemes, disputes about its application , for example, whether a particular factual matrix meets the clinical criteria in section 7(2) or whether a specified event or an inability to obtain appropriate clinical management exists and is related to relevant service under section 10 , would, if they occurred, arise in the claims and review avenues provided by the VEA and MRCA. The instrument does not, however, describe or evidence any such litigation outcomes.

Users seeking judicial or administrative decisions that apply or interpret this SoP should not expect to find that material inside the instrument itself. Instead, they must look to decisions arising in the relevant statutory appeal channels (the VEA and MRCA frameworks) and to any reported decisions that cite RMA SoPs. The instrument does not identify any reported decision or provide a litigation timeline; the only procedural history it records is the replacement of the 2012 SoP by this 2018 SoP (section 4). The document is therefore silent on litigation history.

The instrument contains several textual features and limitations that can produce practical pitfalls for claimants and decision-makers. These are points that often cause disputes in claims processes because of their narrow wording and cross-references:

• Clinical thresholds are binary and narrow: The definition of moderate to severe TBI requires at least one of five specific criteria (section 7(2)(a)(i)-(v)). A claimant with a traumatic brain injury that does not meet any one of those five indicators will not meet the definition in this SoP. For example, an individual with a GCS of 13 or higher and no documented loss of consciousness beyond 30 minutes, and without anterograde amnesia exceeding 24 hours and no structural imaging abnormality, falls outside this SoP’s defined condition even if they have a history of head trauma (section 7(2)). The Note recognises other consequences of brain trauma are covered by other SoPs, but a failure to satisfy these specific thresholds will be decisive for this SoP.

• Exclusions: The definition expressly excludes injury from radiation, electricity, heat and surgery (section 7(2)(b)). If the asserted brain injury was the result of any of those mechanisms, the SoP’s definition does not apply.

• Timing of specified event: Section 9(1) requires “experiencing a specified event at the time of the clinical onset of moderate to severe traumatic brain injury.” The Schedule defines specified events tightly (head struck by object, head striking object, acceleration/deceleration movement without direct external trauma, foreign body penetration, explosion or blast). The instrument therefore demands that a specified event temporally coincide with the clinical onset; cases where a specified event precedes onset by some interval, or where the event is uncertain, may raise difficult factual questions for decision-makers (section 9(1) and Schedule definition of “specified event”).

• Narrow availability of inability-to-treat factor: Section 9(2) provides an alternative factor , inability to obtain appropriate clinical management , but section 10(2) confines its application to material contribution/aggravation where the TBI was suffered or contracted before or during, but did not arise out of, the person’s relevant service. That means claimants whose moderate to severe TBI arose during service as a result of service cannot rely on the inability-to-treat factor if the injury in question “arose out of” service. The statutory wording creates a potential trap for claimants and advisers who may expect health‑system access issues to be available in more circumstances than the SoP permits.

Compliance in this context means preparing and presenting a claim for moderate to severe TBI (or death from it) so that the minimum factors and the clinical definition in the SoP are satisfied for the purpose of raising a reasonable hypothesis linking the condition to relevant service. The SoP itself sets the minimum content; the steps below follow directly from the instrument’s requirements.

1. Identify whether the condition falls within the SoP definition: Use the clinical criteria in section 7(2). Ensure the claim demonstrates at least one of:

   • Loss of consciousness longer than 30 minutes (section 7(2)(a)(i));
   • Anterograde amnesia longer than 24 hours (7(2)(a)(ii));
   • Intracranial lesion, including abnormality attributable to the injury seen on conventional MRI or CT (7(2)(a)(iii));
   • Penetration of the dura mater (7(2)(a)(iv));
   • Glasgow Coma Scale score less than 13 (7(2)(a)(v)).

   If none of those clinical features can be established, the injury does not meet this SoP’s definition and a different SoP may be applicable (note to section 7(2)).

2. Determine which factor under section 9 you will rely upon:

   • If relying on a specified event at the time of clinical onset (9(1)), ensure the event matches the Schedule’s definition of a “specified event” (Schedule 1): head struck by an object; head striking an object; brain undergoing acceleration/deceleration without direct external trauma; foreign body penetrating the brain; or explosion/explosive blast.
   • If relying on inability to obtain appropriate clinical management (9(2)), confirm that the TBI was suffered or contracted before or during, but did not arise out of, the person’s relevant service (section 10(2)). This factor is therefore only available in limited circumstances.

3. Establish the relationship to relevant service:

   • Section 10(1) requires any factor relied upon under section 9 to be related to the person’s relevant service. Use the Schedule’s definition of “relevant service” to confirm the service category (operational, peacekeeping, hazardous service, British nuclear test defence service under the VEA, or warlike/non-warlike under the MRCA). The claimed event or treatment access issue must be tied to that service period or circumstances.

4. For claims involving death, link the terminal event:
