(1) Subject to this section and section 9A, for the purposes of this Act, an injury suffered by a veteran shall be taken to be a war - caused injury, or a disease contracted by a veteran shall be taken to be a war - caused disease, if:
(a) the injury suffered, or disease contracted, by the veteran resulted from an occurrence that happened while the veteran was rendering operational service;
(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;
(c) the injury suffered, or disease contracted, by the veteran resulted from an accident that occurred while the veteran was travelling, while rendering eligible war service but otherwise than in the course of duty, on a journey to a place for the purpose of performing duty or away from a place of duty upon having ceased to perform duty;
(d) the injury suffered, or disease contracted, by the veteran is to be deemed by subsection (2) to be a war - caused injury or a war - caused disease;
(e) the injury suffered, or disease contracted, by the veteran:
(i) was suffered or contracted while the veteran was rendering eligible war service, but did not arise out of that service; or
(ii) was suffered or contracted before the commencement of the period, or last period, of eligible war service rendered by the veteran, but not while the veteran was rendering eligible war service;
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 accident--that incapacity shall be deemed 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) if 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 happened 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 route for a reason 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.
(7) Despite subsection (1), the injury or disease of a veteran is taken not to have been war - caused if that injury or disease is related to the veteran's eligible war service only because:
(a) in the case of a veteran who had not used tobacco products before 1 January 1998--the veteran used tobacco products after 31 December 1997; or
(b) in the case of a veteran who had used tobacco products before 1 January 1998--the veteran increased his or her use of tobacco products after 31 December 1997.
