PRINCIPLES OF CONSTRUCTION
14 In Australian Securities and Investment Commission v DB Management Pty Limited (2000) 199 CLR 321 at 338 [34]-[35] Gleeson CJ, Gaudron, Gummow, Hayne and Callinan JJ said:
'[34] In Project Blue Sky Inc v Australian Broadcasting Authority ((1998) 194 CLR 355 at 384, per McHugh, Gummow, Kirby and Hayne JJ), after pointing out that the duty of a court is to give the words of a statutory provision the meaning that the legislature is taken to have intended them to have, the majority said:
"Ordinarily, that meaning (the legal meaning) will correspond with the grammatical meaning of the provision. But not always. The context of the words, the consequences of a literal or grammatical construction, the purpose of the statute or the canons of construction may require the words of a legislative provision to be read in a way that does not correspond with the literal or grammatical meaning."
[35] It may be added that, if a party contends that a provision, by reason of such considerations, should not be given its literal meaning, then such a contention may lack force unless accompanied by some plausible formulation of an alternative legal meaning.'
15 Earlier, in Project Blue Sky Inc v Australian Broadcasting Authority (1998) 194 CLR 355 at 381 [69] McHugh, Gummow, Kirby and Hayne JJ said that the primary object of statutory construction was to construe the relevant provision so that it is consistent with the language and purpose of all of the provisions of the statute. They approved what Dixon CJ had said in Commissioner for Railways (NSW) v Agalianos (1955) 92 CLR 390 at 397, namely that:
'… the context, the general purpose and policy of a provision and its consistency and fairness are surer guides to its meaning than the logic with which it is constructed.'
16 And, in Public Transport Commission (NSW) v J Murray-Moore (NSW) Pty Limited (1975) 132 CLR 336 at 350 Gibbs J said that where two meanings were open '…it is proper to adopt that meaning that will avoid consequences that appear irrational and unjust'. Inconvenience or improbability of result may assist the Court in preferring, to the literal meaning, an alternative construction which is reasonably open and more closely conforms to the legislative intent: CIC Insurance Ltd v Bankstown Football Club Ltd (1997) 187 CLR 384 at 408 per Brennan CJ, Dawson, Toohey and Gummow JJ. They noted that both the common law and s 15AB of the Acts Interpretation Act 1901 (Cth) enabled the Court to have regard to reports of law reform bodies to ascertain the mischief to which a provision was directed. There is no relevant explanatory material which might throw light on the obscurity of factor 5(b).
17 The Commission argued that construction placed on factor 5(b) by the Tribunal in Re Schubinski and Repatriation Commission [2005] AATA 1273 at [100] was correct. It argued that, in effect, the last clause of factor 5(b) involves there being no choice for the applicant but to consume an average of not less than 300 grams per week of alcohol. What was meant by 'no choice' was left unexplained.
18 I am of opinion that factor 5(b) should not be construed in this way. The Repatriation Medical Authority had power to determine factor 5(b) pursuant to s 196B(3) of the Act where it was of the view that on sound medical scientific evidence available it was more probable than not that a particular kind of injury, disease or death can be related to eligible war service rendered by veterans. The authority was then obliged to determine a statement of principles in respect of that kind of injury, disease or death. It had to set out the factors that must exist and which of those factors must be related to service rendered by a person before it could be said that, on the balance of probabilities, an injury, disease or death of that kind is connected with the circumstances of that service. Thus, there already had to be in existence sound medical scientific evidence, as defined in s 5AB(2) of the Act, that it was more probable than not that consuming an average of at least 300 grams per week of alcohol for a continuous period of at least six months immediately before the clinical onset of hypertension which can be related to the eligible war service rendered by a veteran.
19 The medical condition of hypertension is defined by factor 2(b) and involves permanently elevated or 'high' blood pressure. Factor 5(b) requires the existence of the consumption of a minimum average amount of alcohol for not less than the six month period immediately before the clinical onset of the disease. Next, 5(b) qualifies the foregoing requirements by adding a further one using the present tense ('which cannot be decreased') in respect of past acts. The objective facts of a person's consumption of alcohol over a period of past history are identified as factors to be established by the first clause in factor 5(b). The other factors set out in factor 5 of the statement of principles all appear to identify factual events (e.g. suffering from chronic renal failure at the time of the clinical onset of hypertension (factor 5(e)), being obese at the time of the clinical onset of hypertension (factor 5(a)), or suffering from sleep apnoea at the time of the clinical onset of hypertension (factor 5(a))).
20 The word 'cannot' in factor 5(b) is used in the present tense. The Oxford English Dictionary defines 'can' as meaning:
'To be able; to have the power, ability or capacity. (Said of physical as well as mental, and of natural as well as acquired ability.)'
21 In its natural and ordinary meaning in factor 5(b) the word 'cannot' means that it is not possible to decrease the quantity. In other contexts the word 'cannot' has a natural and ordinary meaning of excluding the possibility of something occurring. So, in 29 Equities Ltd v Bank Leumi (UK) Ltd [1986] 1 WLR 1490 at 1496G-H Dillon LJ said that it was a simple question of fact to be decided in the light of common sense whether at the date on which a vendor purported to rescind a contract of sale a licence 'cannot be obtained'. And, in The Newbattle (1885) 10 PD 33 the English Court of Appeal held that a statutory provision referring to a ship which 'cannot be arrested' connoted that it was impossible to arrest the ship. In Rhymney Iron Company v Gelligaer District Council [1917] 1 KB 589 at 594, Viscount Reading CJ had to construe a provision empowering a local authority to service a notice on an owner or occupier where the person responsible for a nuisance 'cannot be found'. He said that having regard to the public health purpose in the legislation, the authority had only to be unable to ascertain, in its then state of knowledge, who was responsible for the nuisance.
22 Each of these cases, of course, is on a different phrase or statutory provision and shows that the word 'cannot' must be construed in accordance with the principles of statutory construction to which I have referred.
23 Factor 5(b) does not refer to concepts of alcoholism, alcohol abuse or alcohol dependency. Each of those concepts may involve the need to establish a state of mind on the part of an applicant in which the consumption of alcohol is or is not involuntary, or can or cannot be controlled.
24 A strict literal reading of factor 5(b) suggests that even where a veteran is suffering from a form of addiction to alcohol but could, if he or she chose, reduce the intake (e.g. by being admitted to an institution at which alcohol dependency could be treated and at which no alcohol was permitted) but did not do so would not be capable of satisfying the conditions. Any possibility of a person consuming less than the average 300 grams of alcohol per week would negate a claim which had been medically established by the actual consumption of that quantity. In effect, a person who was caused by his or her service to the nation to embark on a drinking habit of consuming more than 300 grams of alcohol per week, and who became sick with hypertension, would not be able to receive a benefit because it was logically possible for him or her not to have drunk as much. Such a construction is, in the absence of express words, one which produces consequences which are irrational and unjust (Public Transport Commission (NSW) v J Murray-Moore (NSW) Pty Limited (1975) 132 CLR 336 at 350 per Gibbs J.
25 There is no textual indication in factor 5(b) as to the degree of possibility involved in the concept of 'cannot be decreased' on the construction posited by the Commission. Many veterans would miss out on having their claims considered if a standard were applied of such a draconian kind in its absolute terms. The tribunal noted, drawing on the reasoning on the Full Court of this Court in Repatriation Commission v Tuite (1993) 39 FCR 540 at 541 and 545, Mr Cotton's introduction to alcohol occurred during his service from his being involved with other recruits and trainees as well as others in a service environment. The Tribunal was particularly well constituted to make such a finding, having as its members Rear Admiral Horton AO and Dr Thorpe. It would be perfectly possible to frame a factor under s 196B(3)(c) by reference to precise medical conditions. Indeed, a previous statement of the principles concerning hypertension (instrument No 32 of 2001) did so.
26 However, what the present factor 5(b) says that it is a condition that a minimum amount of alcohol be consumed and that it cannot be decreased. Even if one were to construe the word 'cannot' as meaning that it was not possible at the time of the consumption to decrease the amount consumed, the inclusion within the same definition of the two concepts leads to a real risk of circulatory. It must always be possible to reduce one's consumption of alcohol. It would be odd for the factor to prescribe a level of consumption and then to deny it having an effective operation by using a criterion, if it could be read as the Commission suggests, which would always render reference to the factor to be pointless.
27 Here, the purpose of a statement of principles, and in particular the obligation of the authority to set out 'the factors that must exist' (s 196B(3)(c)), show that the construction put forward by the Commission is of such an indefinite character that it would not fulfil the requirements of the statute. The authority eschewed the identification of a particular medical condition or other precise state of facts in using the expression 'which cannot be decreased' in factor 5(b). That removed any objective standard by reference to which an hypothesis could be understood if the last clause is to be read as relevant to the applicant, his or her conduct or state of mind. If a literal reading is appropriate it clearly requires that there be no logical possibility of decreasing alcohol consumption below 300 grams per week. Then no-one could satisfy it. Nor is the standard suggested in Re Schubinski and Repatriation Commission [2005] AATA 1273 at [100] satisfactory. The Tribunal's view in that decision that the words referred to a 'compulsion to drink', does not arise out of the natural and ordinary meaning of the concluding clause of factor 5(b). Moreover, what a 'compulsion to drink' is has been left undefined. It seems to go beyond a recognised illness such as alcoholism. Rather, it connotes incurable alcoholism. If there were a possibility that the alcoholism could have been cured within the period of six months or could have been so affected that the consumption could have been reduced below the threshold in factor 5(b) then the claimant would fail. Moreover, even an incurable alcoholic can be kept in an institution in which that person is not allowed to drink. That is a logical possibility. Any person could be kept in such a condition and therefore every person must fail the test if it is to be construed in a literal way.
28 I am of opinion that the proper construction of factor 5(b) recognises that the present tense is used in the verb 'cannot' to emphasize to the decision-maker that the consumption of an average of at least 300 grams per week of alcohol for the continuous period of at least six months immediately preceding the clinical onset of hypertension is not to be ignored under any circumstances. Thus, even where the medical evidence might demonstrate that the veteran consumed less than 300 grams per week of alcohol immediately before the clinical onset of the hypertension and that that consumption was, as matter of fact, clinically causative of the condition, the concluding clause excludes the exercise of that clinical conclusion from consideration by the decision-maker.
