Tribunal's findings on compensability
8 The Tribunal then considered whether either of the conditions was compensable under the 1988 Act. It did so on the basis that the applicant's claim for compensation had been lodged on 24 May 1996. It found that as at that date:
"the applicant claimed compensation under the 1988 Act in respect of "osteoathrosis" in the "left knee/ left middle finger" which became symptomatic in 1987 (in the case of the left knee) and the early to mid 1990s (in the case of the left middle finger) and which he attributed to the motor cycle accident in which he was involved in January 1952."
9 In relation to the left knee condition, in respect of which the applicant at first suffered osteoarthritis in 1987, the question was whether that condition was compensable under the 1988 Act which in turn depended on whether it was compensable under the Compensation (Commonwealth Government Employees) Act 1971 ("the 1971 Act"): see s 124 of the 1988 Act. That in turn made the Commonwealth Employees' Compensation Act 1930 ("the 1930 Act") relevant. The Tribunal referred to the relevant statutory provisions as follows:
"49. Under s27(1) of the 1971 Act personal injury was, subject to and in accordance with the Act, compensable by the Commonwealth in the case of an injury caused to an employee "arising out of or in the course of the employment of [the] employee by the Commonwealth". Section 29 of that Act relevantly provided:
"(1) Where -
(a) an employee contracts a disease…; and
(b) any employment of the employee by the Commonwealth was a contributing factor to the contraction of the disease…,
the succeeding provisions of this section have effect.
(2) If -
…
(e) the total or partial incapacity for work of the employee,
results from the disease … then, for the purposes of this Act, unless the contrary intention appears -
(f) the contraction of the disease … shall be deemed to be a personal injury to the employee arising out of the employment of the employee by the Commonwealth; and
(g) … the date of the commencement of the incapacity or the date on which the medical treatment was first obtained, whichever is the earlier, shall be deemed to be the date of injury."
In s5(1) of the 1971 Act the term "disease" was defined to include
"any physical or mental ailment, disorder, defect or morbid condition, whether of sudden onset or gradual development"
and the term "injury" was defined, relevantly, to mean "any physical or mental injury" but, subject to s29, not to include a disease."
10 In applying these provisions the Tribunal concluded as follows in respect of the left knee condition:
"50. The applicant's left knee condition of progressive degenerative osteoarthritis is clearly a "disease" as defined in s5(1) of the 1971 Act. Accordingly, that condition would have been compensable under s29 of the Act provided that the applicant's employment by the Commonwealth was "a contributing factor" to the contraction of that disease. The Tribunal has already found (see paragraphs 42-43 above) on the basis of the medical evidence before it that the applicant's knee condition is not related to or the consequence of, and does not arise out of, his motor cycle accident in January 1952 or his employment by the Commonwealth. Accordingly, the Tribunal finds that the applicant's motor cycle accident in January 1952 or his employment by the Commonwealth was not a contributing factor to the contraction of his present left knee condition. That condition would not, therefore, have been compensable under the 1971 Act. It follows that that condition is not compensable under the 1988 Act."
11 In relation to the left middle finger condition, the arthritis had first been suffered in the early to mid 1990s so that the question whether the condition was compensable fell to be determined under the provisions of the 1988 Act alone. The Tribunal reasoned as follows in relation to this aspect:
"52. The relevant provisions of the 1988 Act - namely s14(1) and the definitions of "ailment", "disease", "injury" and "impairment" in s4(1) - have already been set out in paragraph 45 above.
53. The applicant's left middle finger condition is clearly an "ailment", as defined in s4(1) of the 1988 Act. In order to constitute an "injury" (being a "disease"), within the meaning of the definitions of those terms in s4(1) of the 1988 Act, however, that condition (or "ailment") must be one that "was contributed to in a material degree" by the applicant's employment by the Commonwealth. In order to constitute an "injury (other that a disease)", within the meaning of the definition of the term "injury" in s4(1) of the 1988 Act, on the other hand, that condition must constitute a physical injury "arising out of, or in the course of," the applicant's employment. The Tribunal has already found (see paragraphs 42-43 above) on the basis of the medical evidence before it that the applicant's left middle finger condition is not related to or the consequence of, and does not arise out of, his motor cycle accident on 24 January 1952 or his employment by the Commonwealth. Likewise, the Tribunal finds that the applicant's left middle finger condition or "ailment" was not "contributed to in a material degree", or at all, by his motor cycle accident in January 1952 or his employment by the Commonwealth. That condition is, therefore, neither an "injury" (being a "disease") nor an "injury (other than a disease)", as defined in s4(1) of the 1988 Act and is, accordingly, not compensable under s14(1) of that Act."
12 Accordingly, the Tribunal affirmed the decision under review and it was not necessary for it to consider other issues raised by the parties.
