18 HWT also submitted that it had been denied natural justice, it having had no notice before the direction was made. The learned trial Judge did not consider it necessary to rule on this submission, on the ground that the proceeding had been commenced only to obtain answers to the questions of statutory construction.
The appeal: statutory construction
19 In this Court, HWT renewed its contentions as to the proper construction of s.146(4)(b). Its first submission was that, once a request for access to a file had been made, the Tribunal simply had no power to give a direction to the contrary. The alternative submission was that, even if the power subsisted after the access request was made, it was exercisable only if a party to the proceeding sought such a direction.
20 According to HWT, s.146 on its proper construction confers on a non-party a right, upon payment of the prescribed fee, to be granted immediate inspection of a proceeding file. Once the fee is paid, so it is argued, the entitlement to access is indefeasible, whether under s.146(4)(b), (c) or (d). This is said to be the natural and ordinary meaning of the words used. The phrase "on paying the prescribed fee" is said to import a temporal element, to connote "a concept of immediacy". HWT contends that s.146(4)(b) is a provision "designed to derogate from the open administration of justice" and must therefore be construed strictly and narrowly.[8]
21 On the alternative submission, HWT draws attention to the fact that the Act confers on the Tribunal a number of powers which are expressed to be exercisable on the Tribunal's own initiative.[9] HWT argues that a "careful choice" appears to have been made by the legislature, between those powers exercisable on the Tribunal's own initiative and those exercisable only on the application of a party. There being no indication in s.146(4)(b) that the Tribunal may act on its own initiative in giving a contrary direction, it must follow - so HWT argues - that the power is exercisable only on the application of a party.
22 Since both of these arguments are directed at confining the Tribunal's power to give a contrary direction for the purposes of s.146(4)(b), it is necessary to say something about the source of that power. At the trial, HWT argued that the power was to be found in s.146(4)(b) itself, while counsel for the Tribunal argued that the source of the power was s.80 of the Act, which confers a general power to give directions. The trial Judge concluded that s.80(1) was the source, a conclusion which HWT has not challenged in this appeal.
23 With respect to his Honour, I think that the power to give a contrary direction derives - albeit only by implication - from s.146(4)(b) itself. The general power under s.80(1) is a power given to the Tribunal for the management of proceedings and hence is exercisable "at any time in a proceeding" - but not otherwise. The question of access to a proceeding file may well arise long after the proceeding has concluded, whether by Tribunal determination or by mediated settlement. In those circumstances, there being no extant proceeding, it must follow that the s.80(1) power would not be available.[10] Approaching the matter a different way, the function of deciding whether to limit access to a proceeding file is a purely administrative function of the Tribunal, separate from the Tribunal's function of conducting proceedings before it. It is the latter function to which s.80(1) relates.
24 On this view, the Act contains no express conferral on the Tribunal of power to give a direction of the kind contemplated by s.146(4)(b). Since, however, the provision assumes the existence of such a power, the power is to be implied, in accordance with established principle. Such an implication is a matter of necessity. Without it, the provision could not operate. [11]
25 HWT seeks to have the (implied) power to give directions construed as subject to limitations on its exercise. Since there is nothing in s.146(4)(b) - or in s.146 as a whole - which can be read as imposing any such limitations, HWT can only succeed if the limitations contended for are themselves required - as a matter of necessary implication - for the effectual operation of the provision in accordance with the legislative intent.[12]
26 In my view, no such implication is warranted. The regulation of access to files which s.146(4)(b) contemplates does not assume, less still necessarily involve, any implied limitation on the power to give a direction. On the contrary, the effective regulation of access would seem to assume the existence of a wide and general power, exercisable at any time and in any circumstances, as occasion requires. Moreover, the generality of the language in sub-paragraph (b) - "any direction of the Tribunal to the contrary" - allows of no reading down. Had Parliament wished to limit the power in the ways HWT contends it should be limited, provision could readily have been made to that effect.
27 This conclusion accords with the approach of the Act as a whole, which grants the Tribunal wide powers to control and manage proceedings. Powers of that nature are essential for a tribunal which, as a creature of statute, has no inherent jurisdiction. As to the "careful choice" said to have been made in conferring "own initiative" powers on the Tribunal, counsel for the Tribunal concede that there are provisions which state expressly that a power may be exercised on the Tribunal's own initiative. They correctly point out, however, that there are other provisions in the Act which confer powers on the Tribunal without so stating but where the nature of the power is such that it must have been intended to be exercisable on the Tribunal's own initiative.[13] In short, there is no clear demarcation of the "own initiative" powers.
The appeal: natural justice
28 As already noted, the learned trial Judge declined to deal with the question of natural justice, that is, whether HWT was entitled to be heard before the Tribunal decided whether or not to give a direction for the purposes of s.46(4)(b). In the originating motion by which the judicial review proceeding was initiated, breach of natural justice was not identified as a ground of review. As the Judge noted, the order of the Senior Master, by which the proceeding was referred for hearing in the Practice Court, recorded that the contentions of HWT would be confined to matters of statutory construction.
29 The natural justice question was, however, fully argued on the appeal. It is a point of general importance to the Tribunal's practice and, as will appear, it is also of particular importance in the present case. Accordingly, it is appropriate for this Court to decide the question and, for that purpose, I would grant leave to HWT to amend its originating motion to add the natural justice ground.
30 HWT's argument is attractively simple. The steps in the argument are as follows:
