Statement of Principles concerning occipital neuralgia (Balance of Probabilities) (No. 74 of 2025)

The central concept is occipital neuralgia, defined in subsection 6(2) with considerable specificity. The definition requires unilateral or bilateral paroxysmal attacks of severe pain of shooting, stabbing or sharp quality, in the posterior scalp distribution of the greater, lesser and/or third occipital nerves, lasting seconds to minutes. The pain must be associated with dysaesthesia (unpleasant sensation) and/or allodynia (pain from innocuous stimulation such as brushing hair). There must be tenderness over affected nerve branches or trigger points at the emergence of the greater occipital nerve or in the distribution of the second cervical nerve. Critically, the definition explicitly excludes cervicogenic headache, cluster headache, migraine, tension-type headache, and trigeminal neuralgia. This means a claimant who presents with migraine-like features or tension headache will not meet the SoP definition, even if a clinician labels the condition occipital neuralgia. The ICD-10-AM code M54.81 is noted, but the SoP definition overrides that code for application purposes (subsection 6(3)-(4)).

Death from occipital neuralgia is defined in subsection 6(5) to include death from a terminal event or condition contributed to by the person’s occipital neuralgia. “Terminal event” is defined in the Schedule 1 Dictionary and includes pneumonia, respiratory failure, cardiac arrest, circulatory failure, or cessation of brain function. This broadens the chain of causation but only if the occipital neuralgia itself contributed to the death.

Factors are listed in section 8. They include: concussion or moderate to severe traumatic brain injury within 3 months before clinical onset or worsening; trauma to the neck or back of the head within 3 months; surgery involving the upper neck or base of skull within 6 months; cervical spondylosis involving upper cervical spine; a mass lesion compressing, displacing or infiltrating the upper cervical spinal cord, spinal nerves or occipital nerve; acute herpes zoster involving the affected occipital nerve within 6 months; a list of diseases involving the upper cervical spinal cord (Behcet syndrome, infarction, multiple sclerosis and clinically isolated syndrome, myelitis, neuromyelitis optica); rheumatoid arthritis of the upper cervical spine; and inability to obtain appropriate clinical management for occipital neuralgia before clinical worsening.

Relevant service is defined in the Dictionary as 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, or peacetime service under the MRCA. This is critical: the SoP does not apply to operational veterans who have the higher “reasonable hypothesis” standard under their own SoPs.

Balance of probabilities is not defined in the instrument but is the standard the RMA has applied in making its determination under section 7. This standard applies to the claim determination as well: the claimant must prove, on the balance of probabilities, that at least one factor exists and is related to service.

Clinical onset and clinical worsening are not separately defined in the instrument, but the factors refer to “clinical onset or clinical worsening” as the timing trigger. Under subsection 9(2), the clinical worsening aspect only applies to material contribution to or aggravation of occipital neuralgia where the condition was suffered or contracted before or during (but did not arise out of) relevant service. This means a pre-existing occipital neuralgia can only be accepted if one of the factors materially worsened it during service.

This instrument directly affects three groups: claimants, decision-makers, and the medical professionals who provide evidence.

Claimants are veterans or members of the Forces who rendered “relevant service” as defined. That includes veterans with eligible war service that is not operational service, defence service that is not hazardous service or British nuclear test defence service, and peacetime service under the MRCA. Veterans with operational service (e.g., service in a declared war or warlike operations) are not covered by this SoP; they fall under a separate reasonable hypothesis framework. This creates a two-track system: the same condition may be accepted more easily for operational veterans because the standard is lower and the factors may be broader. Claimants with non-operational service must satisfy the precise factors on balance of probabilities. Spouses and dependants claiming death benefits are also affected because the SoP defines when death is from occipital neuralgia.

Decision-makers include the Repatriation Commission (Department of Veterans Affairs), the Military Rehabilitation and Compensation Commission, and any reviewer or tribunal (Veterans’ Review Board, Administrative Appeals Tribunal, and the Federal Court on judicial review). They are bound to apply the factors and definitions exactly as written. They cannot add or remove factors, nor can they rely on general medical opinion outside the SoP. The instrument reduces their discretion and standardises outcomes, but it also imposes a heavy evidentiary burden: they must confirm the precise temporal relationships (e.g., within 3 months, within 6 months) and the anatomical specificity (upper cervical levels C1-C3). This may lead to more denials at first instance if medical records are incomplete.

Medical professionals who provide reports for claimants must understand the definition in subsection 6(2) , not just the clinical diagnosis but whether the pain pattern matches paroxysmal attacks, associated dysaesthesia/allodynia, and tenderness. They must also address the exclusion of other headache disorders. If a doctor diagnoses occipital neuralgia but describes features of migraine or cervicogenic headache, the report may be insufficient. Similarly, evidence of trauma, surgery, spondylosis or mass lesions must be localised and timed.

Other stakeholders include the RMA itself, which will monitor the instrument for future review, and compensation insurers (e.g., Comcare) indirectly, because the VEA and MRCA are standalone schemes.

The instrument imposes no duties directly on private individuals. Its legal effect is to define the criteria that must be used when adjudicating claims. The text creates a right for claimants to have their claim determined in accordance with the SoP if the claim is covered by section 120B of the VEA or section 339 of the MRCA. That means the decision-maker must apply the definition in section 6(2) and the factors in section 8. If a claimant satisfies a factor and shows it is related to service, the decision-maker must accept the connection (subject to section 10 cross-referencing). The decision-maker cannot refuse on the basis of a personal medical opinion that the condition is not related.

The instrument also creates a limited right to rely on cross-referenced Statements of Principles. Section 10 provides that if a factor in section 8 refers to an injury or disease for which another SoP has been determined under subsection 196B(3) of the VEA, then the factors in that other SoP apply in accordance with its terms as in force from time to time. For example, factor 8(7) refers to “multiple sclerosis and clinically isolated syndrome”. That is a condition likely covered by its own SoP. To satisfy this factor, the claimant must also satisfy the factors of that SoP to establish that the multiple sclerosis is service-related. This creates a cascading burden of proof.

The duty of the decision-maker is to apply the instrument strictly and accurately. There is no discretion to waive any factor or to accept a factor outside the list. If the claimant does not produce evidence of one of the listed factors, the claim must be refused. This duty is imposed by the VEA itself, reinforced by the binding nature of the SoP under section 196B(14) of the VEA.

The duty of the claimant is to provide evidence that establishes both the existence of the condition as defined and the existence of a factor, with timing and relationship to service. While not a legal duty in the instrument (which is not directed at claimants), failure to do so will result in a refusal. In practice, the evidentiary burden falls on the claimant.

The instrument does not create any rights to review. Those rights arise under the VEA and MRCA separately. The SoP itself is not reviewable on its merits, but the RMA’s decision to make it can be challenged in the Federal Court for jurisdictional error, albeit with a high threshold.

This instrument does not itself contain any penalty provisions. It is a legislative instrument made under the VEA, not a penal statute. However, enforcement mechanisms arise indirectly through the claims system.

If a claimant provides false or misleading information in support of a claim that relies on this SoP, they may be subject to penalties under the VEA (e.g., section 205 for obtaining a payment by false statements) or under the Criminal Code (e.g., offences relating to false information given to a Commonwealth entity). The instrument does not refer to these, but practitioners should be aware that the specific factors and definitions create clear benchmarks. A claimant who falsely asserts they had concussion within 3 months before clinical onset may be caught if records contradict that. Similarly, a medical practitioner who knowingly certifies a condition meeting the definition when it does not may face professional discipline or fraud charges.

Enforcement of the SoP’s application is through the internal and external merits review system. If a decision-maker incorrectly applies the SoP (e.g., by misinterpreting the definition or ignoring a factor), the claimant can seek review by the Veterans’ Review Board, and then the Administrative Appeals Tribunal. The AAT is bound to apply the SoP as a legislative instrument. If the AAT errs in law, judicial review in the Federal Court is available under the Administrative Decisions (Judicial Review) Act 1977 or the Judiciary Act 1903, but the Court cannot substitute its own opinion on the medical factors.

The RMA itself has no enforcement role once the instrument is made. The instrument is enforced through the decision-making hierarchy. There is no penalty for a decision-maker who misapplies the SoP, but the claimant’s rights are enforceable through the review system. The cost of an erroneous denial is borne by the claimant in terms of delay and legal expense, creating an incentive for decision-makers to get it right the first time. However, the lack of direct penalties for erroneous decisions may contribute to a cautious approach by decision-makers, potentially requiring more evidence than the SoP strictly demands.

The instrument sits within a complex legal framework. It is made under subsection 196B(3) of the VEA, which gives the RMA the power to determine a Statement of Principles for the purposes of claims under sections 120B (balance of probabilities for non-operational service) and 339 of the MRCA (which mirrors the VEA standard). This specific SoP does not apply to claims under section 120 (reasonable hypothesis for operational service) or analogous sections of the MRCA. Those claims have their own SoPs or must be assessed under the general test.

Interaction with other SoPs: Section 10 is the key cross-referencing provision. If a factor in section 8 refers to an injury or disease for which an SoP has been determined, then the factors in that other SoP apply. For example, factor 8(4) refers to “cervical spondylosis involving the upper cervical spine”. That condition is likely covered by a separate SoP (e.g., SoP concerning cervical spondylosis). To satisfy factor 8(4), the claimant must not only have cervical spondylosis but also have that condition itself related to service under its own SoP. This creates a chain of causation: the claimant must prove the spondylosis is service-related, then its temporal relationship to occipital neuralgia. This can multiply evidentiary burdens.

Interaction with the VEA and MRCA: The SoP does not override the substantive provisions of those Acts. For example, a claim must still meet the general requirements of the VEA for a pension or allowance. The SoP only determines the question of medical causation. Other issues such as date of effect, rate of payment, and offsets are governed by the Acts and regulations. Also, the definition of “relevant service” in this SoP is narrower than the full definitions in the VEA and MRCA; it excludes hazardous service and British nuclear test defence service, meaning those veterans will have their claims assessed under a different SoP or the general law.

Interaction with state workers’ compensation: The VEA and MRCA are Commonwealth schemes. This SoP does not affect state or territory laws. However, a veteran’s claim under a state scheme may use this SoP as persuasive authority, but not binding.

Interaction with other Commonwealth compensation: The Safety, Rehabilitation and Compensation Act 1988 (SRCA) covers Commonwealth employees. Veterans may also be covered under the SRCA for some conditions. The SoP does not apply to SRCA claims directly, but the RMA’s findings may be used evidentially.

Interaction with tort law: A third party who caused the trauma (e.g., a motor vehicle accident) could be sued. The SoP is irrelevant to liability but the veteran’s compensation from the VEA may need to be repaid if common law damages are recovered (via the VEA’s recovery provisions). The SoP’s definition of occipital neuralgia may also be used in personal injury litigation as part of medical causation analysis, but it is not binding on courts.

The source text for this instrument does not contain any amendment history. The instrument is numbered No. 74 of 2025 and is dated 22 August 2025. By convention, the RMA issues new SoPs that revoke and replace earlier SoPs on the same condition, effective from the commencement date. However, the text of this instrument does not state which prior instrument it revokes, or indeed any amendments it makes. The absence of an amendment history clause is typical for stand-alone SoPs; they are often listed as new instruments that revoke earlier ones by notice in the Federal Register of Legislation. Practitioners should verify the legislative status by checking the register. If a prior SoP on occipital neuralgia existed (possibly under a different number or year), it would have been revoked either by this instrument or by a separate amending instrument. Because the source does not mention any prior instrument, it is safest to assume this is a new SoP that applies to claims made on or after 22 September 2025. It may also apply to claims already in progress if the legislation allows (section 120B of the VEA provides for application of SoPs in force at the time of determination, subject to transitional provisions). The instrument does not contain any transitional savings for claims lodged before commencement.

The instrument itself does not refer to any previous litigation concerning occipital neuralgia or any challenge to earlier SoPs. The source provides no information about court decisions that have interpreted this specific instrument or its predecessors. However, it is well known that SoPs are frequently the subject of judicial review in the Federal Court, typically on grounds that the RMA failed to comply with procedural requirements under the VEA (e.g., failure to consider available medical-scientific evidence, or making a determination not supported by the evidence). The Full Federal Court has established that the RMA’s decisions are reviewable for jurisdictional error, but not on merits. The High Court has also considered SoP issues, particularly in Repatriation Commission v McKenna (1999) 86 FCR 441 and Repatriation Commission v Williams (2003) 75 ALD 697, though these are not cited in the source.

Given that this instrument is brand new (2025), there is no litigation history specific to it. Practitioners should search for decisions of the Veterans’ Review Board and the AAT that apply this SoP, as those decisions may clarify the interpretation of the definition or the factors. The absence of litigation history does not mean the instrument is uncontroversial; its narrow definition and the exclusion of common headache disorders are likely to generate disputes. Claimants whose symptoms overlap with migraine or cervicogenic headache may argue that the RMA’s definition is unduly restrictive, but the instrument is clear on its face. Any challenge on that basis would need to be a judicial review attack on the reasonableness of the RMA’s determination, which is difficult to mount if the RMA followed its statutory procedures.

The instrument contains several traps for the unwary.

Narrow definition: The definition in subsection 6(2) is more restrictive than a standard clinical diagnosis. A neurologist may diagnose occipital neuralgia based on tenderness and response to nerve blocks, even if the pain is not strictly paroxysmal or does not have the specific associated features. The SoP requires all subparagraphs (a), (b) and (c) of subsection 6(2) to be met, plus the exclusions in (d). Many claimants with what is commonly called occipital neuralgia will not satisfy this definition if their pain resembles chronic tension-type headache or if it is continuous rather than paroxysmal. The note says “occipital nerve entrapment is an example” but that does not relax the definition’s criteria.

Exclusions: The explicit exclusions of cervicogenic headache, cluster headache, migraine, tension-type headache, and trigeminal neuralgia are absolute. A claimant who has any of these conditions cannot rely on the SoP, even if they also have occipital neuralgia. The decision-maker must exclude those diagnoses based on the clinical evidence. If a doctor notes features of migraine (e.g., photophobia, unilateral throbbing pain) alongside occipital pain, the claim may fail.

Time limits: Many factors in section 8 have precise windows: concussion or traumatic brain injury within 3 months before clinical onset or worsening (factor 8(1)); trauma to neck/head within 3 months (factor 8(2)); surgery within 6 months (factor 8(3)); herpes zoster within 6 months (factor 8(6)). These are strict. If the trauma occurred 4 months before onset, the factor is not satisfied. There is no allowance for slow progression. The “before clinical worsening” aspect for pre-existing conditions also requires careful dating.

“Inability to obtain appropriate clinical management” is a factor only for clinical worsening (factor 8(9)), not for onset. It also requires that the inability be demonstrated , merely lacking treatment is not enough; there must be a reason related to service (e.g., service prevented access to treatment). This is a high bar and often difficult to prove.

Relationship to service: Even if a factor exists, section 9(1) requires it to be “related to the relevant service rendered by the person”. For example, a veteran may have cervical spondylosis, but if the spondylosis is due to ageing and not service, the factor fails. The claimant must prove that the factor itself is service-related, not just that the occipital neuralgia is claimed to arise from it. This is similar to a two-step causation.

Cross-referencing trap (section 10): If the factor refers to another condition (e.g., multiple sclerosis, rheumatoid arthritis), the claimant must also satisfy the factors of that condition’s SoP. That SoP may itself have restrictive criteria. The practitioner must trace the chain. If the other SoP has a factor that requires trauma or a particular service event, the claimant may fail to link the root cause.

Relevant service limitation: Only non-operational, non-hazardous, peacetime service qualifies. If a claimant has both operational and non-operational service, the decision-maker must determine which standard applies. The SoP cannot be used for operational claims, which may have more generous factors under a reasonable hypothesis SoP.

Death claims: The definition of “death from occipital neuralgia” requires contribution to a terminal event. This is worded broadly but may be difficult to prove if the occipital neuralgia was not a direct cause of death (e.g., if death was from cancer, but occipital neuralgia was a comorbid condition). The terminal event list is broad but requires evidence that the occipital neuralgia contributed, not just coexisted.

For a decision-maker (claims officer or tribunal member):

1. Determine whether the claim is made under section 120B of the VEA or section 339 of the MRCA, and whether the person’s service is “relevant service” as defined. If the person has operational or hazardous service, this SoP does not apply; use the reasonable hypothesis SoP instead.

2. Determine whether the claimed condition meets the definition in subsection 6(2). Obtain medical reports that clearly address each element: paroxysmal attacks, distribution, quality, duration, associated dysaesthesia/allodynia, tenderness over nerve branches or trigger points, and exclusion of the listed headache disorders. If the definition is not satisfied, the claim must be refused even if one of the factors exists.

3. If the definition is satisfied, identify which factor or factors in section 8 the claimant relies on. For each factor, require evidence of the specific medical condition or event (e.g., concussion diagnosis, imaging of cervical spondylosis, surgical records) and evidence of the timing relative to clinical onset or worsening.

4. Ensure the factor itself is related to the person’s relevant service. For example, if relying on trauma to the neck, the trauma must have occurred during or be attributable to service. The same applies for all factors: the underlying condition must be service-related, not just the occipital neuralgia.

5. If the factor refers to another injury or disease covered by another SoP (e.g., multiple sclerosis), apply that SoP as if the claimant had made a claim for that condition. Only if that SoP’s factors are satisfied can the original factor be deemed to exist.

6. Consider the clinical worsening provisions under subsection 9(2) if the condition was pre-existing. Require evidence that the factor resulted in material contribution to or aggravation of the occipital neuralgia, and that the aggravation is more than a temporary fluctuation.

7. Document all reasoning, citing the specific paragraphs of the instrument relied on.

For a claimant or legal representative:

1. Obtain a diagnosis that strictly aligns with the SoP definition. Ask the specialist to specifically comment on the paroxysmal nature, distribution, associated dysaesthesia/allodynia, tenderness, and exclusion of other headache disorders. A generic diagnosis may be insufficient.

2. Gather records that establish one or more factors. For concussion or traumatic brain injury, obtain medical records of the event and diagnosis. For trauma to neck or head, get ambulance, hospital or GP records showing the time and nature of injury. For surgery, obtain operation notes. For cervical spondylosis, get imaging reports and a specialist opinion that it involves upper cervical levels (C1-C3). For mass lesions, get radiology and pathology.

3. Prove the timing. Each factor has a specific window. If the trauma occurred 4 months before onset, the claim fails. Consider whether a different factor (e.g., cervical spondylosis that pre-existed) might apply.

4. For clinical worsening claims, obtain evidence that the occipital neuralgia existed before or during service but did not arise out of service, and that one of the factors caused material worsening during service.

5. Address the cross-referencing trap. If relying on multiple sclerosis, for example, obtain evidence that the multiple sclerosis itself meets its own SoP factors and is service-related.

6. Keep records of any inability to obtain appropriate clinical management if that factor is used.

7. Be aware that the SoP may be subject to judicial review if the RMA made an error, but this is a long shot. Focus on fitting within the criteria.

Compliance is essentially evidentiary. The instrument rewards meticulous medical documentation and penalises vague or inconsistent reporting. Decision-makers should not accept a claim that does not match the definition even if it seems medically reasonable. The SoP is binding, and the only safe path is to apply its terms strictly.
