LEGISLATIVE BACKGROUND
11 By s 13(1) of the Act, the Commonwealth is liable to pay a pension to a veteran who has become disabled from war-caused injury or disease. Section 9(1) of the Act sets out the circumstances where the injury or disease is taken, for the purposes of the Act, to be "war‑caused". Relevantly, this will occur when:
"(a) the injury suffered, or disease contracted, by the veteran resulted from an occurrence that happened while the veteran was rendering operational service; [and]
(b) the injury suffered, or disease contracted, by the veteran arose out of, or was attributable to, any eligible war service rendered by the veteran …"
12 The question of whether a veteran is suffering from an injury or disease, and the diagnosis of that injury or disease is to be determined to the "reasonable satisfaction of the decision-maker": see s 120(4) of the Act; Benjamin v Repatriation Commission (2001) 34 AAR 270 at [54]-[55].
13 For a disability claim to be accepted by the Commission, the disability must be related, by a reasonable hypothesis, to operational war service: s 120(3). Section 120A(3) provides that a hypothesis connecting a person's injury or disease with his or her service is only reasonable where there is in force a Statement of Principles ("a SoP"), and the hypothesis is consistent with the SoP: Repatriation Commission v Deledio (1998) 83 FCR 82 at 86; Deledio v Repatriation Commission (1997) 47 ALD 261 at 275.
14 The relevant parts of ss 120 and 120A of the Act are set out below:
"120(1) Where a claim …. for a pension in respect of the incapacity from injury or disease of a veteran … relates to the operational service rendered by the veteran, the Commission shall determine that the injury was a war-caused injury, that the disease was a war-caused disease … as the case may be, unless it is satisfied beyond reasonable doubt, that there is no sufficient ground for making that determination.
(2)…
(3) In applying subsection (1) or (2) in respect of the incapacity of a person from injury or disease, … related to service rendered by the person, the Commission shall be satisfied, beyond reasonable doubt, that there is no sufficient ground for determining:
(a) that the injury was a war-caused injury or a defence-caused injury;
(b) that the disease was a war-caused disease or a defence-caused disease;
…
as the case may be, if the Commission, after consideration of the whole of the material before it, is of the opinion that the material before it does not raise a reasonable hypothesis connecting the injury, disease or death with the circumstances of the particular service rendered by the person.
…
120A(1) …
(2) …
(3) For the purposes of s 120(3), a hypothesis connecting an injury suffered by a person, a disease contracted by a person or the death of a person with the circumstances of any particular service rendered by the person is reasonable only if there is in force:
(a) a Statement of Principles determined under subsection 196B(2) or (11); or
(b) a determination of the Commission under subsection 180A(2):
that upholds the hypothesis.
…"
Reference should be also made to parts of s 196B. Sub-section (2) provides:
"(2) If the [Repatriation Medical] Authority is of the view that there is sound medical-scientific evidence that indicates that a particular kind of injury, disease or death can be related to:
(a) operational service rendered by veterans;
…
the Authority must determine a Statement of Principles in respect of that kind of injury, disease or death setting out:
(d) the factors that must as a minimum exist; and
(e) which of those factors must be related to service rendered by a person.
before it can be said that a reasonable hypothesis has been raised connecting an injury, disease or death of that kind with the circumstances of that service."
Sub-section (14) relevantly provides:
"(14) A factor causing, or contributing to, an injury, disease or death is related to service rendered by a person if:
(a) it resulted from an occurrence that happened while the person was rendering that service; or
(b) it arose out of, or was attributable to, that service; or
(c) …
(d) it was contributed to in a material degree by, or was aggravated by, that service;
(e) …
(f) …
(g) …"
15 The method by which these provisions are to be applied was explained by the Full Court in Repatriation Commission v Deledio at 97-98. a four stage process is involved:
"1. The Tribunal must consider all the material which is before it and determine whether that material points to a hypothesis connecting the injury, disease or death with the circumstances of the particular service rendered by the person. No question of fact finding arises at this stage. If no such hypothesis arises, the application must fail.
2. If the material does raise such a hypothesis, the Tribunal must then ascertain whether there is in force an SoP determined by the Authority under s 196B(2) or (11). If no such SoP is in force, the hypothesis will be taken not to be reasonable and, in consequence, the application must fail.
3. If an SoP is in force, the Tribunal must then form the opinion whether the hypothesis raised is a reasonable one. It will do so if the hypothesis fits, that is to say, is consistent with the "template" to be found in the SoP. The hypothesis raised before it must thus contain one or more of the factors which the Authority has determined to be the minimum which must exist, and be related to the person's service (as required by ss 196B(2)(d) and (e)). If the hypothesis does contain these factors, it could neither be said to be contrary to proved or known scientific facts, nor otherwise fanciful. If the hypothesis fails to fit within the template, it will be deemed not to be "reasonable" and the claim will fail.
4. The Tribunal must then proceed to consider under s 120(1) whether it is satisfied beyond reasonable doubt that the death was not war-caused, or in the case of a claim for incapacity, that the incapacity did not arise from a war-caused injury. If not so satisfied, the claim must succeed. If the Tribunal is so satisfied, the claim must fail. It is only at this stage of the process that the Tribunal will be required to find facts from the material before it. In so doing, no question of onus of proof or the application of any presumption will be involved."
16 The Full Court further held that, where a SoP applies, it prescribes the essential content of a reasonable hypothesis pursuant to s 120(3), and, in order to satisfy ss 120(3) and 120A(3) of the Act, the hypothesis must incorporate each element that the SoP prescribed in order to make the hypothesis reasonable.
17 All features of a disease as relevantly defined in the applicable SoP must be present in order to connect that disease with a person's service: Repatriation Commission v Gosewinckel (1999) 59 ALD 690 at [55]; Lees v Repatriation Commission (2002) 125 FCR 331 at [16]; Repatriation Commission v Codd [2005] FCA 888 at [37]; Repatriation Commission v Warren (2008) 167 FCR 511 at [25].
18 An hypothesis connecting a condition defined in the relevant SoP and the eligible service is to comprise a number of factors each of which is consistent with one or more SoPs: Repatriation Commission v McKenna (1998) 52 ALD 72 at 80; approved by the Full Court in McKenna v Repatriation Commission; (1999) 86 FCR 144 at [20]. The factors which must be present to connect a condition to service are those set out in the relevant SoPs. The factors must be related to the service in one or more of the ways listed in s 196B (14) of the Act: Repatriation Commission v Money (2009) 173 FCR 410 at [5].
19 SoPs are made, amended and revoked from time to time. A decision maker who is called upon, in the course of a review of a decision of the Commission, to apply provisions of an SoP, is required, first, to have regard to the SoP in force at the time at which the review decision is made. If that SoP does not uphold the connecting hypothesis, the decision maker is required to consider and apply the SoP which was in force at the time of the Commission's decision: see Repatriation Commission v Gorton (2001) 110 FCR 321 at [44], [64]-[65].
20 McKenna provides a good example of the application of these principles. Mr McKenna had applied for a disability pension for ischaemic heart disease and atherosclerotic peripheral vascular disease. The claim was rejected by the Commission but was allowed by the Board and the Tribunal. The Commission appealed to the Court. At the time at which he made his claim Mr McKenna was already in receipt of a disability pension for incapacity caused by essential hypertension. This diagnosis had been made in 1964 and his claim in relation to this complaint was made in 1984. The onset of Mr McKenna's ischaemic heart disease occurred in 1987 and the onset of his atherosclerotic peripheral vascular disease occurred in 1990.
21 Each of the SoPs for ischaemic disease and for atherosclerotic peripheral vascular disease prescribed as one of the factors which had to be established as the presence of hypertension before the clinical onset of the condition. The SoP for hypertension did not include as a factor, stress on service, which was the basis of Mr McKenna's initial successful claim.
22 The Commission submitted that the Tribunal had failed to consider whether the particular hypothesis raised by the material was upheld not only by the SoPs concerning the two diseases, but also by the SoPs concerning hypertension. It objected that the Tribunal had failed to take into account the fact that the relevant SoP for hypertension prescribed a number of factors which "must as a minimum exist" before it could be said that a reasonable hypothesis had been raised connecting hypertension with the circumstances of military service. Those factors did not include stress, anxiety or psychiatric disturbance. This meant, so it was submitted, that the chain had been broken because there was no link between Mr McKenna's service and hypertension which, in turn, was the condition (factor) on which he relied to establish his new claims.
23 These submissions were upheld by Goldberg J. His Honour said (at 80-82) that:
"For the purposes of s 120A(3) of the Act the hypothesis which has to be upheld by a Statement of Principles is the hypothesis which connects the disease suffered by a veteran with the circumstances of his service. So stated, the hypothesis has to point to a connection which starts with the disease in respect of which the application is made and ends with the service. That connection will comprise a number of links or factors each of which must be upheld by a Statement of Principles and, if need be, by more than one Statement of Principles. In the instant case the relevant links or factors are:
(a) ischaemic heart disease and atherosclerotic peripheral vascular disease
(b) hypertension
(c) stress, anxiety or a psychiatric condition
(d) operational service.
When the hypothesis is identified this way it is then necessary, consistently with the course identified by the full court in Deledio … to ask and answer the question in accordance with s 120A(3)(a) of the Act - is there in force a Statement of Principles that upholds the hypothesis, that is to say the hypothesis connecting each of the diseases contracted by the respondent with the circumstances of his operational service? It is therefore necessary to identify whether there is in force a Statement of Principles which upholds the whole, and not just part, of this hypothesis. This is achieved as between ischaemic heart disease and atherosclerotic peripheral vascular disease and hypertension by the Statements of Principles concerning ischaemic heart disease and atherosclerotic peripheral vascular disease but it is not achieved by reference to the Statement of Principles concerning hypertension. Putting the matter another way, in order to uphold the hypothesis it is necessary to identify a causal link or connection between ischaemic heart disease and atherosclerotic peripheral vascular disease, hypertension and operational service. The lacuna occurs at the point between hypertension and operational service because there is no Statement of Principles which upholds the hypothesis that there is a factor which exists which indicates that a reasonable hypothesis has been raised connecting hypertension with the circumstances of operational service.
…
A hypothesis can only exist for the purpose of connecting an injury suffered or disease contracted by a veteran with the circumstances of the veteran's service if there is a factor, or there are factors, which underpin the hypothesis. In order for a hypothesis to be reasonable, s 120A(3) requires a Statement of Principles to uphold the hypothesis and that Statement of Principles is determined under s 196B(2) or (11). In this case the court is concerned with s 196B(2) which requires a Statement of Principles to set out:
(a) the factors which must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting a disease with the circumstances of a veteran's service
(b) which of those factors must be related to service rendered by the veteran.
When analysed this way it can be seen that the connection of any factors between disease and service rendered must be upheld by one or more Statements of Principles. To say that the hypothesis must be upheld by a Statement of Principles is to say no more than that the relevant factors along the connecting chain, that is to say the links, between the disease the subject of the application and the veteran's service must be supported by a Statement of Principles.
If the respondent's submission was correct he would be left in the present situation with the existence of a factor - hypertension - and the requirement that it be related to his operational service but with a link in the chain of his hypothesis, namely that his hypertension was war-caused, not supported or rather, upheld by any Statement of Principle. If the question is put - how are the diseases war-caused, the answer must be because they are caused by hypertension which may be brought on by stress or psychiatric disturbances. It is this final link in the chain which is not upheld by any Statement of Principle."
