Whether the outcome might have been different if the Tribunal had addressed the employer's argument
61 It remains necessary to consider the merits of the argument that the Tribunal failed to deal with. That is because, as Bennett J explained in Australian Postal Corporation v Sellick [2008] FCA 236 at [35]:
If the particular submission…would not have affected the outcome, failure to advert to it in the reasons does not mean that the matter was not considered and does not give rise to error of law.
62 The employer's argument before the Tribunal involved the proposition that the termination of Mr Dale's employment for wilful misconduct, as a matter of construction of s 19(4) of the Act, necessarily had the consequence that the amount he was able to earn in suitable employment should be regarded as the amount he was earning before the termination. This would mean that AE was equal to NWE under the formula in s 19(2) and that no amount of compensation was payable. It followed, on the employer's argument, that the medical, occupational therapy and other evidence concerning Mr Dale's post injury capacity for employment was irrelevant to the question of his ability to earn income in suitable employment.
63 In my opinion, the employer's argument misconceives the purpose and operation of s 19 of the Act and is wrong, as I will explain. This explanation requires consideration of the statutory provisions in some detail.
64 Part II of the Act has the heading, "Compensation". Section 14, which is found in Division 1 of Part II, provides that Comcare (or a licenced insurer) is liable to pay compensation in accordance with the Act in respect of an injury (as defined) if the injury results in death, incapacity for work, or impairment.
65 Division 3 of Part II has the heading, "Injuries resulting in incapacity for work". Section 19 is then headed, "Compensation for injuries resulting in incapacity". Section 19(1) states that the section applies to an employee "who is incapacitated for work as a result of an injury". The expression "incapacity for work", defined in s 4(9), refers to the employee's incapacity, as a result of an injury, to engage in any work or to engage in work at the same level as immediately before the injury. Accordingly, incapacity for work may be total or partial.
66 Section 19(2) of the Act provides a mechanism for the determination of whether compensation for an employee's loss of earnings due to incapacity for work is payable and, if so, in what amount: Telstra v Slater [2001] FCA 149 at [56]. The evident purpose of the provision is to make Comcare (or a licenced corporation) liable, subject to Part II, to pay a weekly amount of compensation to an employee for the employee's loss of earnings due to incapacity for work as a result of an injury. The provision also describes the way the amount of compensation is to be calculated, namely by applying the formula, NWE minus AE.
67 NWE is the amount of the employee's "normal weekly earnings". Under s 8, an employee's normal weekly earnings are, in essence, the employee's pre-injury weekly earnings. The NWE component is not affected by any subsequent termination of an employee's employment.
68 Under s 19(2) of the Act, AE is defined as the greater of any amount per week that the employee actually earns from employment and any amount per week that the employee "is able to earn in suitable employment". Since the formula requires the greater of the two amounts to be applied, it is always necessary to make an assessment of what employment, if any, is suitable employment for the employee and the amount, if any, the employee is able to earn in such employment. That is not to say that it is always necessary to determine a precise amount: Telstra v Slater at [55].
69 The concept of incapacity for work is crucial under s 19(2) of the Act, but so too is capacity. The phrase "is able to earn" in the definition of "AE" refers to the capacity of the employee to earn income from suitable employment. The definition of "suitable employment" is also concerned with the capacity of an employee to earn income from employment. Section 19(2) requires an assessment of the employee's post-injury ability, or capacity, to earn income from suitable employment.
70 Under s 19(2) of the Act, the amount of compensation payable reflects the difference between an employee's pre-injury earnings and the greater of the employee's post-injury earnings and the amount the employee is able to earn in suitable employment. The provision envisages that in some cases, the earning capacity of an injured employee will be greater that the employee's actual earnings. This is reinforced by paras (b) to (f) of s 19(4). The legislative policy is that an injured employee's underutilisation of his or her earning capacity will, in appropriate circumstances, result in reduction of the amount of weekly compensation payable. That is because compensation under s 19(2) is payable only for loss of earnings due to incapacity for work.
71 The definition of "suitable employment" in s 4(1) of the Act requires that where an employee is no longer employed by the Commonwealth or a licenced corporation, suitable employment is to be assessed by reference to "any employment". There must be an assessment of "work for which the employee is suited". That assessment must have regard to the four categories of matters specified, namely: the employee's age, experience, training, language and other skills; suitability for rehabilitation or vocational training; whether it is reasonable to expect the employee to change his or her place of residence; and any other relevant matter. It is implicit that other relevant matters will include the nature and extent of the employee's injury and the effect of the injury upon the employee's ability to work. The availability of work is also a relevant factor: Martin v Australian Postal Corporation (2000) 32 AAR 199 at [34]-[35]. The exercise of assessing what is suitable employment, and the amount per week that an employee is able to earn from such employment, involves evaluation of all the relevant matters and the exercise of judgment.
72 Section 19(4) of the Act also requires Comcare (or a licensed corporation) to have regard to the matters set out in paras (a)-(g) in determining the amount per week the employee is able to earn in suitable employment. The matters in paras (a)-(f) are factors that can operate to reduce the weekly amount of compensation payable for incapacity (including to zero in appropriate cases). Paragraph (g), which refers to "any other matter that Comcare considers relevant", can operate to reduce the amount of compensation payable or, conversely, to increase the compensation payable notwithstanding paras (a) to (f): see Woodbridge v Comcare (1994) 20 AAR 196 at 205. Again, an evaluative judgment is required.
73 Section 19(4) of the Act provides guidance for the evaluative judgment as to the amount the employee is able to earn in appropriate employment, but does not purport to control that judgment. The requirement is only that the decision-maker "must have regard to" the specified matters. If any of the paragraphs of s 19(4) are found to apply, that does not automatically mean that there must be a reduction of the amount of compensation - no single factor is necessarily determinative: see Woodbridge v Comcare at 206-207; and, on appeal, Woodbridge v Comcare (1995) 21 AAR 201 at 202-203. Nor does s 19(4) purport to control the extent of any reduction.
74 In every case, it is left to the decision-maker to determine the amount per week that the employee is able to earn in suitable employment, taking into account the range of factors set out in the definition of "suitable employment" and in s 19(4) of the Act. No single factor, such as the termination of an employee's employment for misconduct, necessarily determines the answer.
75 The termination of an employee's employment, whether voluntarily or because of dismissal for misconduct, redundancy or some other reason, is a factor that may well be relevant. The precise relevance and significance of the termination will depend upon the circumstances of the case.
76 The judgments in Telstra Corporation v Lyons and Comcare v Line recognise that the possibility of an employer defeating the policy objectives of the Act by terminating an injured employee's employment is relevant to the construction of s 19(4) of the Act. In Comcare v Line, RD Nicholson J observed at [40] that the Act was intended to improve the benefits to employees as a trade off against the removal of the common law right to sue, and that injured employees were to be protected by, inter alia, being provided with rehabilitation and employment. A construction of s 19(4) such that termination of an employee's employment for wilful misconduct must result in the employee receiving no compensation would render it to an employer's advantage to terminate the employment. Such a construction should not readily be adopted.
77 Against this, the employer argues if its construction is not adopted, an injured employee whose employment is terminated for wilful misconduct would be better off than an uninjured employee whose employment is terminated for the same reason. The employer submits that it would be required to pay the equivalent of weekly wages in circumstances where it would not otherwise have been required to pay wages. It argues that such a result would be absurd and could not have been intended by the legislature.
78 The employer's argument conflates the payment of wages with the payment of compensation for incapacity for work. They are not the same. That misconception seems to stem from the employer's conflation of its position as an employer with its liability as a licenced corporation under the Act. In respect of the latter, the employer acts as a self-insurer: see ss 108, 108A, 108B and 108C of the Act. It is not correct to say that because the employer terminates the employment of an employee and is not obliged to pay wages, it is also not obliged to pay compensation. The employer's liability as a self-insurer depends on the statutory requirements.
79 It must be remembered that the object of s 19(2) of the Act is to provide for compensation for an injured employee's loss of earnings due to incapacity for work as a result of injury. An injured and incapacitated employee remains injured and incapacitated following the termination of his or her employment. An uninjured employee whose employment is terminated retains his or her full capacity to earn income by obtaining other employment. An injured employee whose employment is terminated for wilful misconduct is not better off than an uninjured employee terminated for wilful misconduct in any relevant sense. The employer is correct to say that termination of an employee's employment may be a relevant matter. However, the employer's argument that termination of employment for wilful misconduct must result in the amount the employee is able to earn in suitable employment being taken to be the amount earned in his or her employment before the termination, with the consequence that no compensation is payable under s 19(2), must be rejected.
