Judgment
1BASTEN JA: The applicant, Mr Robert Lennon, has been employed as a driver by TNT Australia Pty Ltd ("TNT") for some 15 years. During the course of that employment he was exposed to loud noise and now suffers a binaural hearing loss, which constitutes a permanent impairment.
2On 24 March 2011 the applicant made a claim for lump sum compensation under the Workers Compensation Act 1987 (NSW) ("the 1987 State Act"). The claim was resisted on the basis that from 1 July 2008 TNT had been licensed under the Safety, Rehabilitation and Compensation Act 1988 (Cth) ("the Commonwealth Act") to make compensation payments in accordance with the scheme provided by the Commonwealth Act. An application was made to the Workers Compensation Commission (NSW) to resolve the dispute. The President, acting pursuant to s 351 of the Workplace Injury Management and Workers Compensation Act 1998 (NSW) ("the Workplace Injury Act"), accepted a question of law for determination as a preliminary issue.
3The question was identified in the proceedings before the President of the Commission as follows:
"Whether by operation of s 17(1)(a)(i) of the Workers Compensation Act 1987 (the 1987 Act), the applicant's binaural hearing loss is deemed to have occurred on 30 June 2008 when the employer ceased to be insured under the New South Wales Workers Compensation Acts or on 24 March 2011 when the claim for compensation was made, at which time the employer was insured under the Safety, Rehabilitation and Compensation Act 1988 (Cth)."
4In Lennon v TNT Australia Pty Ltd [2012] NSWWCCPD 18, delivered on 30 March 2012, the President answered the question as follows:
"By operation of s 17(1)(a)(i) of the Workers Compensation Act 1987, the applicant's binaural hearing loss is deemed to have happened on 24 March 2011, when the claim for compensation was made."
5The present appeal is brought from the answer to that question. The decision being interlocutory, the applicant required leave to appeal: Workplace Injury Act, s 353(4). For the reasons accepted by the President as warranting determination of the question as a preliminary issue in the Commission, and because there are arguable grounds to challenge the correctness of the reasoning in the Commission, a grant of leave is appropriate. It appears to have been assumed that the effect of the answer was that no claim was available under the 1987 State Act. Whether or not that is so, no order has yet been made dismissing the claim. It would have been preferable had the question been formulated in a way which allowed final orders to be made in the event that the question was so answered.
6The question was, however, misconceived for another reason. The formulation of the question no doubt led the President to deal with the matter under the 1987 State Act. Yet it is not in dispute that the applicant is entitled to the compensation claimed under the 1987 State Act, unless that Act is inoperative because inconsistent with a Commonwealth law, pursuant to s 109 of the Constitution. The answer to that question will depend primarily on the scope and operation of the Commonwealth Act.
7The Commonwealth Act provides for workers' compensation for Commonwealth employees, but also allows corporations in competition with Commonwealth authorities or former Commonwealth authorities to enjoy the same conditions in respect of workers compensation as their competitors: Attorney-General (Vic) v Andrews [2007] HCA 9, 230 CLR 369 at [33]-[42]. The liability of TNT under the Commonwealth law depends on the terms of the licence and the terms of the Commonwealth Act. The power to grant licences is vested in the Safety, Rehabilitation and Compensation Commission, established under s 89A of the Commonwealth Act, and is contained in ss 103 and 104. The importance of the terms of the licence flows from s 108(3), which permits the Commission to grant a licence by which the licensee accepts liability in respect of an injury to an employee "occurring at a time before the licence came into force": s 108(1) and s 108A(1).
8The licence was not tendered before the Commission, but it is a public document and a copy, extracted from the Commonwealth of Australia Gazette of 25 June 2008, was provided to the Court by consent. The critical provision, identified in cl 4, authorised the licensee to accept liability in respect of all injuries of any employees of a licensee "where such injuries ... occur within the period of this licence". The licence was expressed to operate for a period of two years from 1 July 2008 until 30 June 2010, but again by agreement of the parties, the Court was invited to assume that the licence has remained in force, pursuant to renewals on similar terms.
9On the basis that the licence covered the kind of injury suffered by the applicant and covered the applicant as an employee of TNT, the critical provisions of the Commonwealth Act were to be found in s 108A, and read as follows:
108A The consequences of a licensee's authorisation to accept liability
(1) If:
(a) a licensee is authorised to accept liability to pay compensation and other amounts under this Act in respect of particular injury, loss or damage suffered by, or in respect of the death of, some or all of its employees; and
(b) such injury, loss, damage or death occurs;
then:
(c) the licensee is liable to pay compensation and other amounts under this Act in respect of that injury, loss, damage or death; and
(d) Comcare is not liable to pay compensation or other amounts under this Act in respect of that injury, loss, damage or death.
...
(7) If a licensee who is a corporation is authorised to accept liability to pay compensation and other amounts under this Act in respect of a particular injury, loss or damage suffered by, or in respect of the death of, some or all of its employees after the licence comes into force then:
(a) no law of a State or Territory relating to workers compensation applies to a licensee in respect of such injury, loss, damage or death; and
(b) any liability or obligation of the corporation under a law of a State or Territory in respect of such injury, loss or damage suffered, or death occurring, before the licence came into force is unaffected.
10The references to "loss or damage" can be ignored; in relation to compensation payments, the Act uses these terms to refer primarily to property damage: ss 14 and 15. The first question raised by s 108A(1)(b) is when the injury "occurs" for the purposes of the Commonwealth Act. Injury includes a "disease": s 5A. "Disease" is defined:
5B Definition of disease
(1) In this Act:
disease means:
(a) an ailment suffered by an employee; or
(b) an aggravation of such an ailment;
that was contributed to, to a significant degree, by the employee's employment by ... a licensee.
11"Ailment" is defined to mean "any physical or mental ailment, disorder, defect or morbid condition (whether of sudden onset or gradual development)": s 4(1), ailment. The time at which an employee sustains an injury, being a disease, is dealt with in s 7:
7 Provisions relating to diseases
...
(4) For the purposes of this Act, an employee shall be taken to have sustained an injury, being a disease, or an aggravation of a disease, on the day when:
(a) the employee first sought medical treatment for the disease, or aggravation; or
(b) the disease or aggravation resulted in the death of the employee or first resulted in the incapacity for work, or impairment of the employee;
whichever happens first.
12It is clear that the hearing loss has not resulted in the applicant's death or incapacity for work; accordingly the date on which the injury was sustained must be either the date when the applicant first sought medical treatment for his hearing loss or the date of the "impairment", whichever happened first. The evidence as to the application of s 7(4) of the Commonwealth Act was limited. A statement made by the applicant dated 5 July 2010 said that he "first noticed [his] hearing loss a couple of years ago": paragraph 14. There was also evidence of an assessment of permanent impairment undertaken on 1 March 2011. No finding has been made (or could satisfactorily be made absent evidence directly addressing the issues) as to when either of these events occurred. Accordingly, the Court must proceed on the basis of contingencies.
13Section 108A(7) adopts different language from that used in s 7(4): it provides that no State law relating to workers compensation applies to a licensee in respect of an injury "suffered by" its employees after the licence comes into force. There being no submission to the contrary, the Court should assume that references in the Commonwealth Act to an injury occurring, being sustained or being suffered all convey the same meaning.
14There was a difference of view as to the proper construction of s 108A(7). Counsel for the Attorney General for New South Wales submitted that the phrase at the end of the chapeau, "after the licence comes into force" applied to the time at which the licensee was authorised to accept liability to pay compensation (and thus came under an obligation to pay it), without backdating under s 108(3). That is an awkward reading of the language, suggesting that the words "after the licence comes into force" should have followed immediately upon the words of obligation to pay amounts "under this Act". The alternative construction is that the temporal clause applies to the time the injury is suffered. As s 108(3) permits liability to extend to injury occurring before the licence came into force, on any view the latter construction is preferable.
15It would follow that a similar construction should apply to the temporal clause "before the licence came into force" at the end of paragraph (b). Not only does that clause follow immediately upon the reference to injuries suffered, but, if it were intended to qualify the liability or obligation of the corporation under State law, it would be necessary to insert the words "which arose" before the temporal clause, in order to give it grammatical effect. The preferable reading is that paragraph (b) refers to an injury which was suffered before the licence came into force.
16As a separate element of the construction of s 108A(7), the phrase "such injury" in each of paragraphs (a) and (b) must refer back to the kind of injuries covered by the licence, as identified in the chapeau, without picking up the temporal clause "after the licence comes into force".
17If, by application of the Commonwealth Act, the injury occurred after the licence took effect on 1 July 2008, the State Act did not apply: s 108A(7)(a). If the injury had, by application of the Commonwealth Act, arisen before the licence came into force, then that Act would not apply to it: that is, s 108A(1) and (7) read together do not envisage a licence applying except in respect of an injury suffered after it comes into force.
18However, if the Commonwealth Act did not apply, it would not be inconsistent with a State Act. Because the tests under s 7(4) of the Commonwealth Act and 17(1) of the 1987 State Act differ, a single injury of gradual onset could be taken to have occurred at different dates under each provision. If, for the purposes of the Commonwealth Act, the applicant first sought medical treatment for his hearing loss or the impairment arose before the date of the licence, the Commonwealth Act would not apply to that injury. According to the President, under the State Act the applicant's loss was deemed to have happened on 24 March 2011, when the claim for compensation was made. If that were correct, the State Act applied in its terms, and TNT was an employer subject to liability under the State Act, regardless of the existence of the Commonwealth licence. Because the State and Commonwealth Acts must each be applied in its own terms, the result is not anomalous.
19The opposite disparity could also arise; that is, the Commonwealth law might determine that the injury occurred after the licence came into force, but under the State law an entitlement may have arisen prior to the licence coming into force, thus creating a liability in the employer under the State law, preserved by s 108A(7)(b). Double compensation is avoided in such circumstances by the Commonwealth Act withdrawing its benefits: s 118(1).
