Section 81(1) ought to be construed as imposing a prima facie absolute obligation upon an employer to pay compensation in accordance with the Act whenever an employer receives a claim which, in its terms, is a claim for compensation in relation to an injury to a worker employed by him. The following sub-sections of s.81 confirm that construction, and, in particular, militate against construing the reference to "a claim for compensation in relation to an injury to a worker employed by him in respect of which the employer is liable to pay compensation in accordance with this Act" as enabling the employer at any time to go behind the assertions made in the form of claim. If any issue is to be raised by the employer by way of disputing liability to pay compensation at all (as distinct from a right to terminate a weekly payment) then subs.(2) and (3) of s.81 provide the exclusive method of doing so. If an employer avails himself of the provisions of s.81(2), the Commissioner has the powers referred to in s.81(3) and that provision is to be taken as exhaustively providing for the matters which may be dealt with by the Commissioner upon a reference under s.81(2)(b). The "matter" referred to in s.81(2)(b) does not encompass the dispute. The determination of the Commissioner upon such a reference determines the question as to whether weekly payments are to be made pending a resolution of the dispute. It does not involve a resolution of that dispute. Even if the effect of a determination by the Commissioner under s.81(3) is that weekly payments are to continue, the dispute remains unresolved. The claim for compensation has not then been settled by agreement. The Commissioner may resolve the dispute but only if his jurisdiction is further invoked by a party making another application. It would be open to a party to the dispute to refer the matter to the Commissioner under s.42(1). It might be thought that if the Commissioner had determined that s.81(1) should apply notwithstanding the dispute, then the employer or the licensed insurer would be motivated to apply. On the other hand, if the Commissioner determined that s.81(1) should not apply, the worker would have an incentive to apply under s.42. As an alternative to a reference under s.42 a party is entitled to refer such a dispute to the Secretary under s.40. The provisions of s.81(4) lend support to these propositions, in that a determination that s.81(1) should apply is not to be taken into account "in any other proceedings", indicative of a legislative intent that separate action be taken to actually resolve the dispute which action is to be taken under s.40 or under s.42. In summary:
