(a) Is the Director's ultimate decision vitiated if a reasonable time has lapsed?
70 My reasons for concluding that breach of the Director's obligation to make a decision within a reasonable time does not result in a loss of jurisdiction under s 93(1) are as follows.
71 As the parties agreed, the issue falls to be determined with reference to ordinary principles of statutory construction, which requires appropriate consideration to be given to the text, context and purpose of the relevant statutory provisions.
72 Applying that approach, I make the following findings, which largely accord with the Director's submissions:
(a) Nothing in the text of the Act explicitly stipulates that a referral decision must, on pain of invalidity, be made within a reasonable time. Rather, the critical question is whether the implied requirement for the Director to make a decision under s 93 within a reasonable period of time is accompanied by an additional statutory implication that the Director loses jurisdiction to make such a decision after a reasonable time has lapsed.
(b) The absence of express text to that effect contrasts with the express provisions of the Act stipulating specific timeframes (e.g. one month, 12 months), following expiry of which statutory consequences follow: see, for example, ss 86(2), 88A(3), 94(1) and 106R(1) and (2).
(c) I consider that there is no warrant to imply into the Act a condition to the effect that, upon the expiry of a reasonable time, jurisdiction to refer under s 93(1) is lost. Such an implication cannot be justified where the Parliament has chosen expressly to regulate the circumstances in which jurisdiction is lost by reason of delay in this heavily regulated statutory scheme, which includes not only s 94(1) but also other express provisions which make clear whether non-compliance with a time requirement produces invalidity (see, for example, ss 106G(5) and 106TA(2)). The applicant does not suggest that the express circumstances in s 94 apply here. I accept the Director's submissions that the applicant's case is undermined by s 94(1), not assisted by it.
(d) I also accept the Director's submission that an improbable consequence of the applicant's proposition is that she could lose jurisdiction because, although the express 12 month timeframe in s 94(1) was not reached, a "reasonable time" had nevertheless expired. Such an unlikely outcome could scarcely have been intended. In its outline of written submissions in chief, the applicant contended that the outer boundary for a reasonable time in the circumstance of this case is 12 months from the date of the resumption of the review (see [47]). Accordingly, the applicant seemed to accept that, depending upon the facts and circumstances of a particular case, the "reasonable time" might be a period less than that outer boundary. This serves to highlight the force of the Director's submission that jurisdiction to make a referral is not lost simply because a "reasonable time" has lapsed. I do not accept that submission.
(e) Nor is there room for such an implication to be drawn in the face of the scheme of Div 3A of Pt 7AA, which allows for only three outcomes following a review. First, the Director may decide to take no further action under s 91, if satisfied of the matters set out in that section. (The Director may also be deemed to have made such a decision by force of s 94, but the Second NHDS Judgment establishes that that provision does not apply here). Secondly, the Director may enter into an agreement with the person under review, of the kind referred to in s 92 (albeit that is the end of the matter only if the agreement is ratified (s 92A), and s 92 has no operation here because it applies only where the person under review is a "practitioner"). Thirdly, the Director may make a referral under s 93. I accept the Director's submission that the review cannot be left unresolved. The review can result in no further action being taken only if the Director decides (or is deemed to decide) upon that course in accordance with s 91.
(f) I accept the Director's submission that the statutory scheme here is quite different from the scheme described in Calwell at 573-574, where an officer was empowered to do something of his or her own motion upon the occurrence of some event (i.e. without a request or application), and the position may be that that thing can only be done within a reasonable time. The statutory regime here requires the Director to decide, one way or another, on a matter raised before her. Similarly, in Plaintiff S297/2013 v Minister for Immigration and Border Protection [2014] HCA 24; 255 CLR 179, the statutory process of decision-making was enlivened by the fact that a person had made a visa application. Here, the decision-making processes required of the Director are triggered by a request made by the Chief Executive Medicare. In such cases, I consider that the obligation to decide within a reasonable time is capable of being enforced by mandamus or an injunction. It is not to the point that NHDS itself had no interest in seeking any such relief in the present circumstances. It is inapt to describe the result of the Director's construction as leaving the timing of a referral under s 93 as entirely at the Director's discretion. The issue is one of statutory construction, which should not be driven by the facts and circumstances of any particular case, as emphasised in the Second NHDS Judgment at [50]. Here, outside the circumstances that the Parliament has expressly covered in s 94, I accept the Director's submission that there is no sensible reason to infer a legislative intention that delay would dictate the substantive outcome of the review (by making s 93 unavailable).
(g) Nothing in the extrinsic materials indicates any contemplation by the Parliament that, upon expiry of a reasonable time, the Director would lose jurisdiction to make a referral decision.
(h) It may be accepted that the task of determining whether or not there should be implied into this statutory regime a condition to the effect that jurisdiction to make a decision under s 93 is lost where a reasonable time has passed necessarily requires consideration of all relevant provisions in the statutory scheme. However, I consider that the applicant has overstated the significance of statutory provisions whose purpose is to protect the interests of persons such as itself who are regulated by the statutory scheme. True it is that those provisions are not irrelevant to the task, but they should not be overstated. In particular, it is notable that the express object of Pt VAA of the Act, as stated in s 79A, focuses upon protecting the Commonwealth and the community from misuse of the Medicare scheme, as opposed to giving primacy to protecting the rights and interests of practitioners and others who benefit professionally from the Medicare scheme.
(i) Nor is there any reason of statutory purpose why the suggested implication should be made. It can be accepted that (as with most statutory schemes involving inquiry and decision-making) it is good policy to make decisions as soon as practicable. To make that observation does not, however, indicate whether there is also a statutory purpose that decisions not made within that time are a priori invalid. As stated in the Second NHDS Judgment at [46], there is always a question as to how far the Parliament has chosen to go in pursuing an identified purpose. I accept the Director's submission that the policy that decisions be made within a reasonable is sufficiently achieved by the power of the Director to take into account delay as a discretionary reason not to refer, and the potential for a person under review to obtain injunctive relief or mandamus to require the Director to fulfil any duty she has to act expeditiously (see Project Blue Sky Inc v Australian Broadcasting Authority [1998] HCA 28; 194 CLR 355 at [100] per McHugh, Gummow, Kirby and Hayne JJ). The potential availability of those remedies to compel the Director to make a decision within a reasonable time is inconsistent with the applicant's contention that the implied time limit must have a "hard edge" because otherwise the timing of a referral under s 93 would be left entirely to the discretion of the Director.
(j) I also accept the Director's contention that the applicant, at least in its written submissions, has elided two quite distinct legal propositions. At [30] of its written submissions in chief, the applicant suggested that the issue of "reasonable time" is an objective fact, presumably akin to a jurisdictional fact. However, at [32]-[33] of that outline, it introduced the quite distinct area of principle relating to the exercise of statutory discretionary powers. The legal and practical distinction between the two principles is reflected in the significance of the material before the decision-maker (which is generally irrelevant in the former case, and highly relevant in the latter case) and the standard of review (in the former, the matter is generally for the Court, whereas in the latter, matters are generally for the decision-maker subject to error). The importance of maintaining the distinction between jurisdictional facts and matters going to legal unreasonableness was emphasised by Gummow ACJ and Kiefel J in Minister for Immigration and Citizenship v SZMDS [2010] HCA 16; 240 CLR 611 at [39] (in a passage referred to by French CJ in Li at [22]).
(k) I consider that there is some force in the Director's contention that the applicant's motive in attempting to grasp onto legal unreasonableness cases is presumably to attempt to bring itself within the general presumption that functions must not, on pain of invalidity, be exercised in a legally unreasonable way, in circumstances where every other textual and structural indication in the Act points against delay being jurisdictional. In my view, the label of "legal unreasonableness" is of minimal utility in the particular circumstances here. It provides limited guidance in determining whether, in the exercise of statutory construction, there is an implication that jurisdiction to make a decision under s 93 evaporates if the Director does not act within a reasonable time.
73 I also accept that the Director's submission that the applicant's reliance on a line of authority which includes NAIS is a distraction. That line of authority is concerned with the circumstances in which delay by a judge or tribunal in giving judgment or a decision may evidence appealable error. Importantly, however, as Gleeson CJ explained at [5], "the ground of appellate intervention is the error, or the infirmity of the decision, not the delay itself". Here, the only basis on which the decision is impugned is delay, not error said to be caused or contributed to by delay.
