Statement of Principles concerning benign paroxysmal positional vertigo (Balance of Probabilities) (No. 57 of 2017)

The central organising concept is the definition of BPPV itself. Subsection 6(2) requires both symptom and sign: recurrent vertigo episodes of less than one minute, provoked by specific head movements; and either the observation of nystagmus during a provoking manoeuvre (such as the Dix-Hallpike test) or evidence of response to treatment with repositioning manoeuvres (such as the Epley manoeuvre). This definition excludes positional vertigo that lasts more than one minute (such as central positional nystagmus) and vertigo that is not provoked by head movements. It also excludes cases where no nystagmus is seen and no response to repositioning is documented, even if the clinical history is otherwise typical. For claims purposes, a diagnosis of BPPV by a treating doctor is insufficient unless the diagnostic criteria in subsection 6(2) are met.

The instrument distinguishes between clinical onset and clinical worsening. The factors in subsections 8(1) to 8(7) apply to the first appearance of BPPV. The factors in subsections 8(8) to 8(14) apply to a material contribution to or aggravation of pre-existing BPPV, but only if the BPPV was suffered or contracted before or during (but did not arise out of) relevant service. This is a significant limitation: a person whose BPPV first arose during operational service (which is excluded from the definition of relevant service) would not be covered by this statement and would instead rely on a separate statement under the reasonable hypothesis standard. The instrument therefore divides service history into compartments.

The factor list itself reveals the medical assumptions underlying the statement. Most factors involve a direct mechanical or disease insult to the vestibular system. For example, head trauma within 30 days before onset (factor 1) or surgery transmitting vibration to the inner ear within three months (factor 2) point to a clear temporal relationship. Factor 7 requires physical activity at a rate of at least six METs with sudden head turning, jolting or vibration of the body within seven days before onset. This is a high threshold: six METs is roughly equivalent to brisk walking at 6 km/h or moderate cycling, and the activity must involve the specific movements described. The MET definition in the schedule (1 MET = 3.5 ml oxygen per kg per minute) is a standard physiological measure, but applying it to a specific veteran’s activity may require expert evidence. Factor 15, inability to obtain appropriate clinical management, is open-ended. It is the only factor that does not require a discrete event before onset or worsening; it could cover situations where a veteran’s service prevented access to repositioning therapy, but the instrument does not define what constitutes “appropriate clinical management” or whose inability is relevant. This vagueness creates both a potential avenue for claims and a risk of inconsistent interpretation.

The concept of “relevant service” is defined in the schedule to mean 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 a residual category: it captures service that is not the most hazardous type. The RMA chose to issue this statement under the balance of probabilities standard, which applies to all non-operational claims. Operational service, hazardous service and British nuclear test defence service are governed by the reasonable hypothesis standard under separate statements. The effect is that a veteran with operational service who develops BPPV must meet a lower evidentiary threshold (reasonable hypothesis) but uses a different statement; the present statement only applies to less risky service. The statement’s reach is therefore narrower than a reading of the title might suggest.

The primary population subject to this statement is veterans and members of the Australian Defence Force who have rendered relevant service and who claim compensation for BPPV or death contributed to by BPPV. Relevant service is limited to eligible war service (other than operational service), defence service (other than hazardous service and British nuclear test defence service), and peacetime service under the MRCA. This excludes the majority of combat veterans, who typically have operational service. The statement therefore affects a narrower subset of claimants than might be expected: those with garrison duties, peacetime training, or home-front service. It also applies to former members who served only during peacetime under the MRCA.

Beyond claimants, the instrument directly binds delegates of the Repatriation Commission and the Military Rehabilitation and Compensation Commission who determine liability for BPPV. These decision-makers must apply the statement as a binding template: if a factor exists and is related to service, they must accept the connection. They cannot substitute their own medical opinion that BPPV is related to service on other grounds not listed. Conversely, if no listed factor is present, they must deny the claim even if they believe BPPV is service-related. This creates a rigid administrative framework that reduces discretion but also risks unfairness where medical science advances beyond the factor list.

Medical practitioners assessing BPPV for compensation purposes are indirectly affected. They need to document the specific diagnostic criteria in subsection 6(2): nystagmus on provocation or response to repositioning. A letter simply stating “BPPV” without objective evidence may not satisfy the claim. For veterans, this changes the incentive structure: they are better off seeking specialist assessment during an attack rather than relying on a GP diagnosis from history alone. The MET requirement for factor 7 also places a premium on activity logs and service records.

Legal professionals and advocates must understand the factor list thoroughly. They need to identify which factor potentially applies, gather evidence of timing (e.g., head trauma within 30 days before onset), and ensure the factor relates to relevant service. The inability to obtain appropriate clinical management factor (15) is a wildcard: it could apply in situations where a veteran serving in a remote location could not access a vestibular therapist, but the statement does not define the standard of “appropriate” or who determines it. This creates uncertainty and potential for conflicting decisions.

The general public is not directly affected. The instrument does not alter the law of torts, workplace health and safety, or NDIS coverage. Its effect is entirely within the military compensation system. However, the RMA’s determination may influence clinical guidelines or other compensation schemes indirectly if the medical evidence findings are cited.

The statement imposes no duties on private individuals except that claimants bear the burden of establishing at least one factor exists and that the factor relates to the person’s relevant service. Section 9(1) explicitly requires that the existence of any factor referred to in section 8 must be related to the relevant service rendered by the person. This is an additional step: even if a factor exists, the causal link between the factor and service must be shown. For example, a veteran who suffered head trauma in a car accident two years after discharge cannot rely on factor 1 because the trauma is not related to service. The duty is on the claimant to adduce evidence of both the factor and the service connection.

The instrument creates a right: if the claimant satisfies the factor and service connection, the decision-maker must treat BPPV as connected with service on the balance of probabilities. That right is enforceable through the usual review mechanisms under the VEA and MRCA, including internal review, review by the Administrative Appeals Tribunal, and judicial review. The statement also gives the RMA the right to determine the medical-scientific basis on which claims are decided, subject to legal constraints such as reasonableness and procedural fairness.

Decision-makers have a duty to apply the statement as in force at the time of the decision. They cannot ignore a factor that is actually present. They also have a duty, under section 10, to apply any other Statement of Principles that covers an injury or disease referred to in the factors. For example, factor 4 requires having Meniere’s disease on the affected side before onset. The existence of Meniere’s disease must itself be determined under its own Statement of Principles. If the Meniere’s disease is not compensable under its own statement, factor 4 cannot be used. This cross-referencing creates a chain of dependencies that can complicate claims.

The RMA’s duty under section 7 was to make the statement “on the sound medical-scientific evidence available”. The statement itself asserts that the RMA is satisfied this standard is met. However, the instrument does not provide for any right to challenge the scientific basis of the factor list within the statement itself. Any challenge would have to be brought by way of judicial review arguing that the RMA’s decision was irrational or not based on the evidence. No such challenges are recorded in this source, but the duty exists as a legal standard.

Importantly, the statement does not confer a right to compensation. It only establishes the evidentiary link. Entitlement to the actual pension or medical treatment depends on other provisions of the VEA or MRCA, including the assessment of impairment and the date of effect. The statement is a necessary but not sufficient condition for payment.

The instrument itself contains no penalty provisions, no offences, and no enforcement mechanisms. It is a purely evidentiary rule. However, its application has financial consequences: claimants who cannot satisfy the factors lose entitlement to compensation. In that sense, the denial of benefits operates as a de facto penalty for failure to meet the evidentiary standard. There is no criminal liability for making a claim that does not succeed, but intentionally providing false evidence to establish a factor could attract charges under the Criminal Code (e.g., obtaining a financial advantage by deception) or under section 137 of the VEA, which penalises false statements. Those penalties are not in this instrument but are triggered if a claimant or witness lies.

The Repatriation Medical Authority does not enforce the statement. Enforcement is carried out by the Repatriation Commission and the Military Rehabilitation and Compensation Commission through the claims process. If a decision-maker suspects that a claimed factor does not exist or is not related to service, they can request further evidence, refer the matter for medical review, or refuse the claim. There is no independent compliance officer for this specific statement.

The risk of strategic behaviour is present. Because factor 15 (inability to obtain appropriate clinical management) is vague, it could be exploited by claimants arguing that they could not get repositioning because of service demands, even if treatment was available but not accessed. The Commission would need to test such claims carefully. Conversely, the closed list of factors means that a claimant with a genuine but idiosyncratic cause (e.g., an explosion causing blast injury to the ear but no direct head trauma) may be denied even though the connection is plausible. This creates an incentive for claimants to fit their story into one of the prescribed factor boxes, which may encourage selective memory or exaggeration.

From an economic perspective, the statement reduces the cost of decision-making by providing a checklist rather than requiring a full medical investigation of causation. The cost savings accrue to the government, but the costs of compliance (gathering evidence of timing, METs, nystagmus) fall on the claimant. If the cost of proving a factor exceeds the expected benefit of the claim, some claimants will not pursue legitimate claims. This is a typical compliance burden effect.

The statement is subordinate to the VEA and MRCA. It is made under subsection 196B(3) of the VEA, which authorises the RMA to determine Statements of Principles on the balance of probabilities for non-operational service. Section 120B of the VEA and section 339 of the MRCA require decision-makers to apply such statements when determining claims. The statement therefore operates as a mandatory direction within the compensation framework.

Section 10 of the instrument provides a crucial interaction: if a factor refers to an injury or disease covered by another Statement of Principles, that other statement applies in accordance with its terms as in force from time to time. This means the present statement is not self-contained. For example, factor 4 requires Meniere’s disease on the affected side. The existence of Meniere’s disease must be proved by applying the relevant SoP for Meniere’s disease. If that SoP is amended, the reference in this statement automatically picks up the amendment. This dynamic cross-referencing reduces the need for the RMA to update this statement every time a related SoP changes, but it also means that a claimant who would have satisfied a factor under an earlier version of the Meniere’s SoP might find that factor unavailable after an amendment. The statement also interacts with the ICD-10-AM classification system: subsection 6(3) assigns code H81.1 but makes clear that the statement’s own definition prevails. A claim that matches the ICD code but not the statement’s definition would fail.

The statement does not interact directly with state or territory workers’ compensation schemes, motor accident compensation, or common law damages. A veteran could potentially pursue compensation under both the military system and a civil claim (e.g., against a third party who caused the head trauma), but this statement only governs the military claim. There is no double-dipping prohibition in this instrument; that would be found in the VEA or MRCA.

For medical practitioners, the statement interacts with clinical standards. The definition requiring observation of nystagmus or response to repositioning aligns with accepted clinical practice for diagnosing BPPV, so it does not create a conflict. However, the statement may influence medico-legal reports: doctors asked to provide a report for a compensation claim should record whether they performed a Dix-Hallpike test and the result, not just a diagnosis. The MET factor (7) may require the doctor to estimate the metabolic equivalent of an activity described by the claimant, which is not a standard part of a vertigo assessment.

Finally, the statement interacts with other RMA determinations. The RMA issues separate statements for other vestibular conditions (e.g., Meniere’s disease, vestibular neuritis). A claimant with multiple conditions may need to satisfy multiple statements. The system is cumulative.

The instrument records that it was made on 18 August 2017 and commences on 18 September 2017. It is numbered No. 57 of 2017. The source text does not include any earlier versions or amending instruments. There is no indication of whether this statement replaced an earlier statement concerning BPPV. Based solely on the source, the only amendment history is that this is the original instrument with no subsequent amendments reflected. Users should be cautious: the absence of amendment history in the source does not guarantee that no amendments have been made after the source date. Practitioners must check the current Federal Register of Legislation for any amending instruments.

The statement was made by the RMA under subsection 196B(3) of the VEA. That provision was inserted by the Veterans’ Affairs Legislation Amendment Act 1994, but that is not an amendment to this instrument. The statement itself has a single operation date. Under section 2, it commences on 18 September 2017, being the day after 60 days from the date of making (assuming standard tabling and disallowance periods). No transitional provisions are included.

From an economic perspective, the infrequency of amendment reduces compliance costs for decision-makers who can rely on a stable set of factors. However, it also means that if medical science changes (e.g., new evidence linking BPPV to other causes such as migraine or autoimmune disease), the statement becomes outdated. Claimants with newly accepted causal pathways cannot benefit until the RMA issues a new statement. This lag imposes costs on those claimants and may encourage rent-seeking activities such as lobbying for a new statement. The stability of the factor list also creates certainty for the government in budgeting for claims.

The source text does not mention any cases, decisions of the Administrative Appeals Tribunal, or judicial review proceedings. It is not possible from this source to determine whether the statement has been challenged or interpreted in litigation. Based solely on the instrument, the litigation history is a blank slate.

That said, the statement’s structure suggests likely points of legal contest. The definition of BPPV in subsection 6(2) may be challenged as being too restrictive, particularly the requirement for observed nystagmus or response to repositioning. A claimant who has classic symptoms but no objective documentation could argue that the RMA exceeded its power by adding an evidentiary requirement beyond the clinical diagnosis. However, the RMA’s power under s196B(3) is to determine the kind of injury that can be related to service; defining the injury is within its discretion. Any challenge would have to be on administrative law grounds such as unreasonableness or error of law.

The MET factor (7) is another potential litigation target. The definition of MET in the schedule is a scientific unit, but applying it to a specific activity (e.g., “digging trenches” or “carrying a stretcher”) may require expert evidence. Disputes could arise whether an activity reached six METs and whether it involved “sudden head turning, jolting or vibration of the body.” The word “sudden” is not defined, leaving room for argument.

Factor 15, inability to obtain appropriate clinical management, is the most likely source of litigation. The phrase “inability to obtain” implies that clinical management was available but the person could not get it because of service circumstances. What constitutes “appropriate” clinical management? If the standard repositioning manoeuvre (Epley) was not available at a remote base, is that inability? The statement does not specify whose inability matters (the person’s actual inability, or the system’s failure to provide?). Some claimants may argue that the person’s ignorance of treatment constitutes inability. A broad interpretation could expand entitlement significantly. Conversely, a narrow interpretation might require evidence that the person sought treatment and was denied. The lack of definition creates unpredictable litigation risk.

Given the absence of cited case law, this section must be read as a prediction of possible issues, not as a history. The instrument’s legal effect is to channel interpretation of causation, and courts and tribunals will resolve ambiguities over time.

1. Definition trap. Subsection 6(2) requires either “observation of nystagmus during a provoking manoeuver” or “evidence of response to treatment with repositioning manoeuvers.” Many general practitioners do not perform provoking manoeuvres; they diagnose based on history. A claim relying solely on a GP’s diagnosis letter will likely fail. Claimants should ensure a specialist (ear, nose and throat, neurologist, or vestibular physiotherapist) documents objective findings.

2. The 30-day window for trauma factors (1 and 8) is very tight. Most concussive trauma is triaged and documented, but a mild whiplash injury might not be reported. Any delay in seeking medical attention for vertigo beyond 30 days from the trauma invalidates the factor. Claimants must produce evidence of the exact date of trauma and the date of onset of vertigo.

3. Factor 7 requires METs of at least 6 plus sudden head turning, jolting or vibration of the body. Many service activities (marching, running, sitting in a vehicle) may meet the MET threshold but lack the sudden head movement. Driving a truck over rough terrain might involve vibration, but does it involve “sudden head turning”? The word “sudden” implies a rapid, unexpected motion. A claimant who simply turned over in bed (a common BPPV trigger) would not meet the factor because that is not a service activity related to relevant service.

4. Surgery factors (2, 3, 9, 10) cut off at three months or three years. Dental surgery involving vibration (e.g., drilling) is specifically included. However, many dental procedures do not transmit percussive forces to the inner ear; only those like implant placement or wisdom tooth extraction with a hammer and chisel would qualify. The claimant must provide evidence from the dentist about the forces used.

5. Factor 15 is a double-edged sword. It appears to be a catch-all, but it requires that the claimant was unable to obtain appropriate clinical management. If the veteran was aware of treatment but chose not to seek it, or if treatment was available but not accessed, the factor may not be satisfied. The phrase “inability to obtain” suggests an external barrier. The RMA did not define this, leaving it to decision-makers to interpret. This creates uncertainty and a risk of inconsistent outcomes.

6. The worsening factors (8 to 14) apply only if the BPPV was “suffered or contracted before or during (but did not arise out of) the person’s relevant service” (section 9(2)). If the BPPV arose out of operational service (which is not relevant service), the worsening factors do not apply, and a separate statement would govern. If the BPPV arose out of a different period of service (e.g., during peacetime service), the worsening factors might apply but only if the worsening occurred during further relevant service. Complex service histories can defeat claims based on worsening.

7. The statement does not cover death from BPPV unless the death was contributed to by BPPV (subsection 6(5)). BPPV is rarely fatal; death from BPPV would usually be from a fall caused by vertigo. The definition of terminal event in the schedule is a closed list (pneumonia, respiratory failure, cardiac arrest, circulatory failure, cessation of brain function). A fall causing a subdural haematoma that leads to cardiac arrest could qualify, but the chain of causation must be proven. This is a very high bar.

8. Cross-referencing under section 10 means that a claimant might need to satisfy multiple Statements of Principles for the underlying condition (e.g., Meniere’s disease or vestibular neuritis). Those statements have their own factor lists and timing requirements. If the underlying condition is not compensable, the BPPV factor cannot be used.

For claimants: the first step is confirming the diagnosis meets subsection 6(2). Obtain a specialist report that describes a positive Dix-Hallpike test or a successful Epley manoeuvre. The report should state the date of onset of vertigo episodes and note that the vertigo lasts less than one minute. Next, identify which factor from section 8 matches the person’s circumstances. Production of service medical records is critical to establish timing. For trauma factors, obtain the accident report, hospital admission notes, and any diagnosis of head injury with a date. For surgery factors, obtain the surgeon’s notes showing that vibration or percussive forces were transmitted to the inner ear. For factor 7, the claimant must describe the specific physical activity, estimate its intensity (can be done with a MET table), and prove it involved sudden head turning, jolting or vibration. Service records such as training logs, operational orders, or fitness assessments can help. For factor 15, the claimant must demonstrate that appropriate clinical management (i.e., vestibular rehabilitation or repositioning) was not available or could not be accessed because of service circumstances. This might require evidence of remote posting, unavailability of specialists, or delays in access. A statement from a treating physiotherapist explaining that the claimant could not attend appointments due to service demands would be useful.

For decision-makers: verify that the diagnosis matches subsection 6(2) by reviewing clinical notes for nystagmus description or response to repositioning. Do not accept a diagnosis of BPPV from a GP who simply recorded symptoms. Request specialist reports if necessary. For each factor, confirm the timing windows exactly. For factor 7, consider using the Compendium of Physical Activities or a similar reference to assess METs. If the claimant relies on factor 15, require evidence of what “appropriate clinical management” would have been, who would have provided it, and why it was not obtained. Do not assume that inability is established merely by the claimant saying they could not find a therapist.

For medical practitioners providing reports: document your examination technique. If you performed a Dix-Hallpike manoeuvre, note the presence and direction of nystagmus, its latency, and its duration. If you performed a repositioning manoeuvre, note the patient’s response. If you are asked to comment on a factor, state whether the timing and clinical details match the factor. Avoid giving opinions on service connection unless you are familiar with the instrument’s requirements. Be aware that the statement defines BPPV differently from general clinical practice; use the statement’s definition when writing for compensation purposes.

For advocates: build a chronology of the claimant’s service, the onset and any worsening of symptoms, and the occurrence of any factor events. Identify all possible factors, even weak ones, because section 8 requires at least one factor. If the claimant had multiple episodes, determine whether the first onset or a worsening is the relevant event. Check whether the worsening factors are permissible under section 9(2). If a factor refers to an underlying condition like Meniere’s disease, ensure a separate claim or evidence for that condition. Keep copies of the current version of any cross-referenced Statements of Principles, as they may change. Challenge any decision that seems to ignore objective evidence of nystagmus or response to treatment, and if the claim is denied on the basis that a factor is not related to service, ask for a detailed explanation of why the service connection is missing.

For the RMA itself: comply by maintaining the statement on the Federal Register of Legislation and by reviewing it periodically to ensure the factors reflect current sound medical-scientific evidence. The statement’s continued validity depends on the RMA’s ongoing satisfaction that the basis in section 7 remains sound. If new evidence emerges (e.g., linking BPPV to migraine), the RMA should consider amendment. Failure to update could lead to claims being wrongly denied or wrongly granted.
