and, in the opinion of the Commission, the injury or disease was contributed to in a material degree by, or was aggravated by, any eligible war service rendered by the veteran, being service rendered after the veteran suffered that injury or contracted that disease;
but not otherwise.
(2) For the purposes of this Act, where any incapacity of a veteran was, in the opinion of the Commission, due to an accident that would not have occurred, or due to a disease that would not have been contracted, but for his or her having rendered eligible war service or but for changes in the veteran's environment consequent upon his or her having rendered eligible war service:
(a) if that incapacity was due to an acident - that incapacity shall be demed to have arisen out of the injury suffered by the veteran as a result of the accident and the injury so suffered shall be deemed to be a war-caused injury suffered by the veteran; or
(b) in the incapacity was due to a disease - the incapacity shall be deemed to have arisen out of that disease and that disease shall be deemed to be a war-caused disease contracted by the veteran.
(3) Paragraph (1)(a), (b), (c) or (d) does not apply to an injury suffered, or disease contracted, by a veteran if the injury or disease:
(a) resulted from the veteran's serious default or wilful act; or
(b) arose from:
(i)a serious breach of discipline committed by the veteran; or
(ii)an occurrence that happened while the veteran was
committing a serious breach of discipline.
(4) Subsections (1) and (2) do not apply to an injury suffered, or disease contracted, by a veteran if the incapacity of the veteran from that injury or disease resulted from the serious default or wilful act of the veteran that hapened after the veteran ceased, or last ceased, to render eligible war service.
(5) Paragraph (1)(c) does not apply:
(a) to an accident that occurred while the veteran was travelling on a journey from the veteran's place of work in a case where the veteran had delayed commencing the journey for a substantial period after he or she ceased to perform duty at that place (otherwise than for a reason connected with the performance of the veteran's duties) unless, in the circumstances of the particular case, the nature of the risk of sustaining an injury, or contracting a disease, was not substantially changed, and the extent of that risk was not substantially increased, by that delay or by anything that happened during that delay;
(b) to an accident that occurred while the veteran was travelling on a journey, or a part of a journey, by a route that was not reasonably direct having regard to the means of transport used unless:
(i)the journey, or that part of the journey, was made by that routefor a rason connected with the performance of the veteran's duty; or
(ii)in the circumstances of the particular case, the nature of the risk of
sustaining an injury, or contracting a disease, was not substantially changed, and the extent of the risk was not substantially increased, by reason that the journey, or that part of the journey, was made by that route; or
(c) to an accident that occurred while the veteran was travelling on a part of a journey made after a substantial interruption of the journey, being an interruption made for a reason unconnected with the performance of the veteran's duties, unless, in the circumstances of the particular case, the nature of the risk referred to in subparagraph (b)(ii) was not substantially changed, and the extent of that risk was not substantially increased, by reason of that interruption.
(6) Paragraph (1)(e) does not apply to an injury suffered, or disease contracted, by a veteran (being an injury or disease that has been contributed to in a material degree by, or aggravated by, eligible war service rendered by the veteran):
(a) if the aggravation of the injury or disease:
(i)resulted from the veteran's serious default or wilful act;
(ii)arose from a serious breach of discipline committed by the veteran; or
(b) unless the veteran had rendered operational service or the period of
eligible war service rendered by the veteran that so contributed to the injury or disease, or by which the injury or disease was aggravated, was 6 months or longer."
It may be noted that in s9 the draftsperson has not used a constant expression to describe the degree of causal connection to be shown between the injury or disease and the service rendered and the words used to describe that connection include "resulted from", "attributable to", "arose out of", and "arose from". The words "resulted from an occurrence that happened while the veteran was rendering operational service" used in para9(1)(a) suggest a temporal connection between the suffering of injury and the rendering of operational service. The words "arose out of, or was attributable to, any eligible war service rendered by the veteran" in para9(1)(b) suggest a causal connection between the suffering of injury and the rendering of eligible war service.
Sub-sections 9(3), 9(5) and 9(6) qualify the scope of the definitions contained in sub-s9(1) by excluding the operation of that sub-section in circumstances which relate to the suffering of the injury or contraction of the disease or the aggravation thereof. Sub-section 9(4) further excludes the operation of sub-s9(1) where the incapacity from the injury or disease has "resulted from" the circumstances
described in that sub-section. By implication, the meaning of the words "incapacitated from a war-caused injury or war-caused disease" used in s13 of the Act is qualified by the terms of sub-s9(4).
By the combined operation of sub-ss9(1) and 9(3) an injury suffered by a veteran from an occurrence that happened while the veteran was rendering operational service is not an injury to which para9(1)(a) applies, and therefore not a war-caused injury, if the injury resulted from the veteran's serious default, or wilful act, or arose from a serious breach of discipline committed by the veteran, or from an occurrence that happened while the veteran was committing such a breach of discipline.
The wilful act referred to in the expression "serious default or wilful act" is to be taken to be serious misconduct that warrants severe condemnation. (See: McPherson v Repatriation Commission (1989) 87 ALR 275 at 280; Girlock (Sales) Proprietary Limited v Hurrell (1982) 149 CLR 155 per Stephen J at 163.)
The Tribunal did not determine whether the applicant had suffered an injury or contracted a disease but on the material before the Tribunal it appeared to be appropriate for the Tribunal to conclude that the applicant suffered an injury. The word "injury" is defined in sub-s5D(1) of the Act
as any physical or mental injury.
The applicant contends that he suffered a war-caused injury according to the terms of para9(1)(a) of the Act. The Commission contends that the injury suffered by the applicant resulted from the applicant's serious default or wilful act in discharging his rifle to cause the death of the two sergeants.
The Tribunal was satisfied that the material relevant to the applicant's claim was sufficient to suggest that the applicant was incapacitated by an illness, described as "a post traumatic stress disorder", which resulted from an occurrence that happened while the applicant was rendering operational service. A majority of the Tribunal decided that they were "satisfied beyond reasonable doubt that the applicant had sufficient awareness of what he was doing for the collecting and discharging of the firearm to be a wilful act under s9(3)(a)(i) [sic] and also that the discharging of the firearm in an Army camp was a serious breach of discipline committed by the veteran under s9(3)(a)(ii) [sic]" and, therefore, "sub-s120(1) of the Act does not apply to the applicant and his condition is therefore not war-caused".
In referring to sub-paras9(3)(a)(i) and 9(3)(a)(ii) the Tribunal intended to refer to para9(3)(a) and sub-para9(3)(b)(i) respectively. It appears that the Tribunal acted on the assumption that pursuant to the terms of s120 of
the Act the Tribunal had to be satisfied beyond reasonable doubt that the injury suffered by the applicant resulted from the applicant's serious default or wilful act.
The nub of the applicant's contention on "appeal" was that although the Tribunal's understanding that the connection between the injury and a serious default or wilful act or serious breach of discipline had to be proved beyond reasonable doubt was correct, it was contrary to the evidence and, therefore, an error in law for the Tribunal to find that it was satisfied beyond reasonable doubt that the applicant had sufficient awareness of what he was doing for his acts to be wilful acts and for him to understand that he was committing a serious breach of discipline.
The terms of s120 of the Act apply to a claim for a pension under s13 of the Act and the relevant parts of the section read as follows:
"120(1) Where a claim under Part II for a pension in respect of the incapacity from injury or disease of a veteran, or of the death 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.
...
(3) In applying subsection (1) ... in respect of the incapacity of a person from injury or disease, or in respect of the death of a person, 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 ...
(b) that the disease was a war-caused disease ... or
...
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 [or] disease ... with the circumstances of the particular service rendered by the person.
(4) Except in making a determination to which subsection (1) ... applies, the Commission shall, in making any determination or decision in respect of a matter arising under this Act or the regulations, including the assessment or re-assessment of the rate of a pension granted under Part II or Part IV, decide the matter to its reasonable satisfaction.
(5) Nothing in the provisions of this section, or in any other provision of this Act, shall entitle the Commission to presume that:
(a) an injury suffered by a person is a war-caused injury ...
(b) a disease contracted by a person is a war-caused disease ...
...
(d) a claimant or applicant is entitled to be granted a pension, allowance or other benefit under this Act.
(6) Nothing in the provisions of this section, or in any other provision of this Act, shall be taken to impose on:
(a) a claimant or applicant for a pension or increased pension, or for an allowance or other benefit, under this Act; or
(b) the Commonwealth, the Department or any other person in relation to such a claim or application;
