Statement of Principles concerning varicocoele (Reasonable Hypothesis) (No. 79 of 2019)

The instrument introduces and defines several key concepts. The central concept is "varicocoele", which is defined in subsection 7(2) as an abnormal tortuosity and dilatation of the veins of the pampiniform plexus within the spermatic cord in the scrotum. The spelling (varicocoele rather than varicocele) is a deliberate change from the repealed 2011 SoP. The definition is narrower than the ICD‑10‑AM code classification: while the code I86.1 is referenced, the instrument states that the meaning in subsection 7(2) governs. This is a potential gotcha for anyone relying solely on the ICD code.

"Death from varicocoele" is defined in subsection 7(5) to include death from a terminal event or condition contributed to by the person's varicocoele. The Schedule 1 Dictionary defines "terminal event" to include pneumonia, respiratory failure, cardiac arrest, circulatory failure, or cessation of brain function. This expands the scope of compensable death beyond direct varicocoele complications.

"Relevant service" is defined in the Dictionary to mean (a) operational service under the VEA, (b) peacekeeping service under the VEA, (c) hazardous service under the VEA, (d) British nuclear test defence service under the VEA, (e) warlike service under the MRCA, or (f) non‑warlike service under the MRCA. This definition limits the instrument's application to those categories of service; peacetime service under the VEA is not covered.

"Clinical onset" and "clinical worsening" are not explicitly defined but are implicit in section 9: subsections 9(1) to (5) apply to "clinical onset", while subsections 9(6) to (13) apply to "clinical worsening". The distinction is important because the worsening factors only apply where the person's varicocoele was suffered or contracted before or during (but did not arise out of) the person's relevant service (subsection 10(2)). This prevents a claim based solely on aggravation from earning a fresh connection to service if the original condition was not service related.

The "reasonable hypothesis" concept is central to the VEA regime. The instrument's own basis, stated in section 8, is that the Repatriation Medical Authority considers there to be sound medical‑scientific evidence that varicocoele can be related to relevant service. The factors in section 9 are the minimum that must exist for the hypothesis to be raised. They are not exhaustive of the evidence that can be considered, but they are gatekeepers: no factor, no hypothesis.

Other defined terms include "occlusion or stenosis" (complete or partial obstruction from thrombosis, tumour invasion, or external compression), "MET" (a unit of measurement of physical exertion, defined as 1 MET = 3.5 ml oxygen per kg per minute or 1.0 kcal per kg per hour), "increased intra‑abdominal pressure as specified" (acute elevation from lifting, trauma, straining, or manual tools), and "arteries supplying the testis" (cremasteric, deferential, external pudendal, testicular). These definitions are critical for interpreting the factors correctly.

The instrument directly affects two main groups: eligible claimants and decision makers within the veterans' compensation system.

Claimants are veterans, members of Peacekeeping Forces, members of the Forces under the VEA, and members under the MRCA who have rendered "relevant service". This includes those who served in operational, peacekeeping, hazardous, British nuclear test defence, warlike, or non‑warlike capacities. It does not cover peacetime service under the VEA or Defence Force members who served only in a permanent or reserve capacity outside those categories. The instrument also affects their dependants if a death claim is made.

Claimants who suffer from varicocoele and who seek to establish that the condition is service related must satisfy one of the thirteen factors in section 9. For example, a veteran who underwent nephrectomy within one year before developing varicocoele will need to show that the nephrectomy factor is met. A veteran who has ankylosing spondylitis will need to rely on that factor. A veteran whose varicocoele worsened after physical activity of at least 6 METs for six hours per week for four weeks will need to document that activity. Those who cannot point to any factor will likely face rejection of their claim.

Decision makers affected include the Repatriation Commission (the primary claim‑deciding body), the Veterans' Review Board, the Administrative Appeals Tribunal, and the Federal Court. These bodies are bound to apply the instrument as a legislative standard. The instrument reduces their discretionary scope by compelling them to find a reasonable hypothesis raised only when a factor is present. It also requires them to cross‑reference other Statements of Principles when a factor refers to another condition (section 11). This imposes a compliance burden on decision makers to ensure they are using the correct version of each SoP.

Medical practitioners who provide reports in support of claims are indirectly affected. They may need to conduct specific investigations to establish factors such as occlusion or stenosis of the testicular venous drainage system, which may require imaging. The MET factor requires an accurate history of physical activity, which may be difficult to reconstruct for worsening that occurred years after service.

Legal practitioners representing claimants must be familiar with the instrument's structure, the distinction between onset and worsening, and the cross‑reference mechanism. They must also be aware that the instrument only applies if the claim is made under section 120A of the VEA or section 338 of the MRCA; claims under other provisions may not engage this SoP.

The instrument may also affect medical professionals who treat veterans, as they may be asked to provide opinions on whether a factor like "inability to obtain appropriate clinical management" exists. That factor is not defined further and could be contentious.

The instrument does not impose duties directly on individuals, but it creates duties on decision makers and confers procedural rights on claimants.

The primary duty is on the Repatriation Commission, the Veterans' Review Board, and any tribunal or court reviewing a decision to apply the instrument when determining whether a reasonable hypothesis exists connecting varicocoele to relevant service. Section 9 requires that at least one factor must exist before the hypothesis can be raised. This is a strict duty: the decision maker cannot conclude that a reasonable hypothesis exists in the absence of a factor listed in section 9. This shifts the burden of proof from the claimant (who must point to a factor) to the decision maker (who must then consider whether there is contrary proof beyond reasonable doubt).

The duty also extends to considering the relationship between the factor and service under section 10. For initial onset factors (subsections 9(1) to (5)), the factor must be related to the relevant service. For worsening factors (subsections 9(6) to (13)), the factor must also be related to service, but additionally the instrument only applies if the varicocoele was suffered or contracted before or during (but did not arise out of) the relevant service. This means the decision maker must determine the timing and origin of the condition.

Claimants have the right to have their claim assessed in accordance with the instrument. If they satisfy a factor and can show it is related to service, a reasonable hypothesis is raised. If the decision maker then cannot disprove the hypothesis beyond reasonable doubt, the claim must succeed. This right is procedural rather than substantive: the instrument does not guarantee compensation, but it structures the inquiry.

Section 11 creates a duty on decision makers when a factor refers to an injury or disease covered by another Statement of Principles. For example, if the factor is "having ankylosing spondylitis", the decision maker must apply the current SoP for ankylosing spondylitis to determine if that condition is itself service related. This can create a chain of dependencies that complicates the claim.

There is an implied duty on the Repatriation Medical Authority to base the instrument on sound medical‑scientific evidence, as stated in section 8. However, the instrument itself does not create a right for a claimant to challenge the RMA's determination of what constitutes sound evidence. That challenge must occur through judicial review of the SoP itself, which is a legislative instrument.

The instrument does not create any rights regarding other claims, such as those under the Safety, Rehabilitation and Compensation Act 1988 (SRCA) or state workers' compensation schemes. It is confined to the VEA and MRCA.

This instrument does not create criminal offences or civil penalties. There are no fines, imprisonment, or infringement notices for non‑compliance. Enforcement is indirect, through the claims process.

The practical penalty for a claimant who fails to satisfy one of the factors in section 9 is that the claim for compensation for varicocoele will be rejected. This is a significant financial consequence, as compensation may include disability pension, medical expenses, and other benefits under the VEA or MRCA. For dependants claiming death benefits, the penalty is the denial of bereavement payments.

For decision makers, failure to apply the instrument correctly can lead to the decision being set aside on review. If the Veterans' Review Board or the Administrative Appeals Tribunal finds that the Repatriation Commission did not consider a relevant factor or misinterpreted a factor, the matter may be remitted for fresh determination. In extreme cases of jurisdictional error, the Federal Court may quash the decision. There is no financial penalty on the decision maker individually; the cost is borne by the Commonwealth if compensation is wrongly awarded or denied.

The instrument does not have its own enforcement provisions. It operates within the existing review framework under the VEA and the Administrative Appeals Tribunal Act 1975. The Repatriation Medical Authority has no enforcement role regarding individual claims; its role is limited to issuing and revising SoPs.

Potential for abuse exists if claimants fabricate factors such as physical activity levels or increased intra‑abdominal pressure. However, the instrument does not create an offence for false claims; any such fraud would be dealt with under the Criminal Code provisions on obtaining a financial advantage by deception. The instrument itself simply sets the medical standard; it does not police it.

The compliance burden falls mainly on decision makers to ensure correct interpretation of terms like "occlusion or stenosis", "MET", and "increased intra‑abdominal pressure as specified". Misinterpretation can lead to inconsistent outcomes and increased litigation. The instrument's dictionary attempts to reduce ambiguity, but terms like "physical activity" and "manual tools requiring excessive force" leave room for discretion.

The instrument is made under subsection 196B(2) of the VEA and applies to claims under section 120A of the VEA and section 338 of the MRCA. These sections govern the standard of proof for claims relating to service from eligible service. The instrument does not apply to claims under divisions that use a different standard (for example, the "beyond reasonable doubt" standard for certain post‑1994 claims). Its interaction with other laws is primarily through its cross‑reference mechanism and through the broader compensation framework.

Section 11 explicitly provides that where a factor in section 9 refers to an injury or disease for which a Statement of Principles exists under subsection 196B(2) of the VEA, then the factors in that other SoP apply according to its terms as in force from time to time. This creates a chain of legislative instruments. For example, if a claimant relies on factor 4 (having ankylosing spondylitis at the time of clinical onset), the decision maker must consult the current SoP for ankylosing spondylitis to determine if that condition is itself related to the person's service. This can result in multiple SoPs being relevant to a single claim.

The instrument interacts with the MRCA and VEA provisions on the standard of proof. Section 120A of the VEA and section 338 of the MRCA specify that a reasonable hypothesis is raised only if the relevant SoP upholds the hypothesis. The SoPs are therefore integral to the legislative scheme. If the Repatriation Commission or a tribunal misapplies the instrument, the error is a question of law reviewable by the Federal Court under the Administrative Decisions (Judicial Review) Act 1977 or the jurisdiction of the Federal Court under the VEA itself.

The instrument may also interact with evidence laws. The rules of evidence do not apply strictly in Veterans' Review Board proceedings, but the instrument imposes a de facto evidentiary threshold: the claimant must produce evidence that establishes a factor on the balance of probabilities (or perhaps the civil standard implicit in "exists"). Medical reports must be framed with reference to the instrument's definitions.

There is no direct interaction with state workers' compensation laws or motor vehicle accident compensation laws. A veteran who also has a civilian claim for varicocoele would not be bound by this instrument in that context, though a medical practitioner might find the instrument's definitions influential.

The instrument replaces the earlier SoP No. 3 of 2011. Any claims made before 23 September 2019 would have been determined under the old SoP. The repeal in section 4 means that the old instrument no longer applies, but transitional provisions in the VEA may preserve certain rights. The instrument does not contain transitional rules, so the general rule is that the law in force at the time of decision applies.

The instrument (No. 79 of 2019) was made on 23 August 2019 and commenced on 23 September 2019. It repeals the Statement of Principles concerning varicocele No. 3 of 2011 (F2010L03250). The repeal is explicit in section 4. The instrument is the current version; there is no indication in the source that it has been amended since commencement.

The 2011 SoP used the spelling "varicocele"; the 2019 instrument adopts "varicocoele". This may reflect a change in medical nomenclature or a correction of a typographical error. The ICD code I86.1 remains the same. The 2011 instrument likely had a different set of factors, but the source does not reproduce that instrument, so a comparison is not possible from this document.

The authority for making the instrument is subsection 196B(2) of the VEA. That subsection empowers the Repatriation Medical Authority to determine a Statement of Principles about a kind of injury, disease, or death if the Authority is of the view that there is sound medical‑scientific evidence that the condition can be related to relevant service. The Authority must publish the instrument in the Federal Register of Legislation and it is a legislative instrument subject to disallowance by either House of Parliament. No disallowance motions were successful for this instrument.

The instrument includes a "Note" under section 7(2) that varicocoele is associated with male infertility. This note is not binding but may inform interpretation. The inclusion of infertility as an associated issue could affect claims for impotence or infertility under other provisions.

The instrument was made by the Repatriation Medical Authority as then constituted, with Professor Nicholas Saunders AO as Chairperson. The Authority's composition has since changed, but the instrument remains in force until amended or repealed.

There is no sunset clause. The Authority can revoke or replace it at any time if new medical evidence emerges. Given the relatively slow pace of change in understanding varicocoele, the instrument may remain current for many years.

The source does not refer to any litigation specifically concerning this instrument. Because the instrument is a relatively recent legislative determination (2019), it has likely been considered in a number of Administrative Appeals Tribunal and Veterans' Review Board decisions, but no prominent Federal Court decisions are referenced in the instrument itself.

The instrument's predecessor (No. 3 of 2011) may have been litigated. The earlier use of "varicocele" rather than "varicocoele" could have been a point of contention if claimants argued that the spelling difference indicated a different medical condition. The 2019 instrument resolves this by clearly defining the condition in subsection 7(2) and stating that the ICD code I86.1 is not controlling.

The interpretation of "occlusion or stenosis" may give rise to litigation. The definition includes external compression from conditions like "nutcracker syndrome" (left renal vein entrapment). A claimant may argue that a particular anatomical variant qualifies as a stenosis, while the Commission may take a different view. The note listing examples is not exhaustive, so disputes about whether a particular cause falls within the definition are likely.

The "physical activity" factor (factor 11) requires at least six METs for six hours per week for at least four weeks before clinical worsening. The MET definition is given, but estimating historical activity levels is difficult. Litigation may focus on whether self‑reported activity meets the threshold and whether the activity was "continuous" or could be aggregated in short bursts.

The "increased intra-abdominal pressure as specified" definition lists manual tools requiring excessive force such as "pulling forcefully on a large spanner". This is a specific example that could be argued as either in or out of scope. Courts may need to determine whether equivalent activities not listed fall within the meaning.

The cross‑reference mechanism in section 11 could be litigated if a claimant's factor depends on another SoP that itself is under review. For example, if the SoP for ankylosing spondylitis is amended after the claim is lodged but before it is decided, the decision maker must apply the current version. This raises issues of timing and retrospectivity.

Overall, the instrument has not been the subject of a landmark court decision, but it is actively used in claims. Any significant litigation would likely involve the Federal Court and would be reported.

Several aspects of this instrument are easy to overlook.

First, the spelling change: "varicocoele" versus "varicocele". The repealed instrument used "varicocele". If a claimant or practitioner uses the old spelling, a decision maker might argue that the condition is not the same. The instrument is deliberate: it uses the less common spelling throughout. The dictionary and section 7(2) define it, so relying on the ICD code alone is insufficient.

Second, the definition of varicocoele is narrower than common clinical understanding. It requires "abnormal tortuosity and dilatation of the veins of the pampiniform plexus within the spermatic cord in the scrotum". Not all scrotal swellings qualify. A simple varicocele without dilatation or tortuosity might not meet the definition. This could be a trap for claimants who have a diagnosis of varicocele but no imaging evidence of tortuosity.

Third, the distinction between onset and worsening factors. Section 10(2) restricts subsections 9(6) to (13) to situations where the varicocoele was suffered or contracted before or during (but did not arise out of) relevant service. This means that if varicocoele arose out of service, the worsening factors cannot be used to claim further compensation for aggravation. The only factors available for such a case would be the onset factors, but since the condition already arose from service, this may be academic. However, if a veteran had varicocoele before service and it worsened during service, the worsening factors apply.

Fourth, the physical activity factor (factor 11) applies only to clinical worsening, not onset. A claimant cannot rely on physical activity to establish initial onset. The MET threshold of six METs is relatively low; brisk walking is around 5‑6 METs. Six hours per week is about 51 minutes per day. But the activity must be sustained for at least four weeks. This may be difficult to prove if the worsening occurred after a single episode.

Fifth, factors 12(a) and (b) apply only to rupture of varicocoele. Not all cases of varicocoele involve rupture. If the condition is unruptured, these factors are irrelevant. The instrument makes this explicit by prefacing factor 12 with "for rupture of varicocoele only".

Sixth, the cross‑reference in section 11 means that the SoP does not stand alone. To establish ankylosing spondylitis as a factor, the claimant must satisfy the SoP for that condition. That SoP may require its own factors, such as presence of HLA‑B27 or radiographic changes. Claimants may not realise they need to prove the factor condition as service related.

Seventh, "inability to obtain appropriate clinical management" (factor 13) is not defined. This is a broad and potentially vague factor. It could cover situations where the veteran could not access surgery or embolisation due to location, cost, or other obstacles. The difficulty is proving that the inability caused clinical worsening. The factor does not require that the inability be related to service; it just must exist at the relevant time.

Eighth, the note under section 7(2) mentions male infertility. This is not a factor but could be used in claims for infertility as a separate condition. The instrument does not address infertility directly.

Compliance with this instrument is primarily the responsibility of decision makers, but claimants and their representatives must also understand its requirements to present a successful claim.

For the Repatriation Commission, compliance means applying the instrument from the moment a claim for varicocoele is lodged. The decision maker must:

• Confirm that the claimant rendered "relevant service" as defined in the Dictionary.
• Determine whether the claim relates to initial clinical onset or clinical worsening, and apply the appropriate subsections of section 9.
• Identify which factor(s) the claimant asserts.
• Seek medical evidence to support that factor. For example, if the factor is occlusion or stenosis, the decision maker should obtain imaging reports confirming venous blockage.
• For onset factors (9(1)‑(5)), verify that the factor was present before clinical onset. For occlusion or stenosis, this means before the varicocoele developed.
• For worsening factors (9(6)‑(13)), verify that the varicocoele existed before the worsening event and that the worsening is material. Also satisfy that the varicocoele did not arise out of service if the worsening factor is used.
• If a factor involves another condition (e.g., ankylosing spondylitis), consult the current SoP for that condition and determine whether that factor is satisfied under that SoP.
• If a factor is established, confirm that it is related to the person's service. This may require evidence that the occlusion, nephrectomy, arteriovenous fistula, or other condition was caused by service.
• If multiple factors are present, note that only one is required.

For claimants and their representatives, compliance requires proactive gathering of evidence. The following steps are recommended:

1. Obtain a formal diagnosis of varicocoele as defined in the instrument. The diagnosis should be made by a specialist (urologist or radiologist) and should specify tortuosity and dilatation of pampiniform plexus veins.

2. Determine whether the claim is for onset or worsening. Review the timeline of service and varicocoele development.

3. Identify any potential factors. For example, if the claimant had a nephrectomy, check whether the nephrectomy was within one year before onset and on the same side (ipsilateral). If the claimant has ankylosing spondylitis, obtain confirmation of that diagnosis and its connection to service.

4. For the physical activity factor, document the type, intensity, frequency, and duration of activity for at least four consecutive weeks before worsening. Use the MET definition: 6 METs corresponds to activities like jogging, heavy gardening, or carrying moderate loads. Keep logs or obtain witness statements.

5. For the increased intra-abdominal pressure factor, document the specific activity (e.g., lifting heavy weights, trauma, straining from constipation) and the resulting scrotal haematoma. Factor 12 requires the haematoma to occur within seven days before clinical worsening.

6. If relying on factor 13 (inability to obtain appropriate clinical management), provide evidence of what clinical management was considered appropriate, why it was not obtained, and how that caused worsening. This is the most open‑ended factor and may need detailed medical opinion.

Medical practitioners providing reports should use the instrument's definitions and specifically mention the factor being addressed. For example, a report on occlusion should state the vessel affected and the degree of obstruction. A report on physical activity should state the MET value and duration.

Legal representatives should file a submission that maps the evidence to the specific factor and explains the relationship to service. The submission should also address any cross‑referenced SoPs if applicable.

Compliance also involves staying current. The instrument can be amended or repealed. Practitioners should check the Federal Register of Legislation for any updates. The instrument does not have a sunset date, so it remains in force until superseded.
