Consideration
21The Tribunal's procedural power that are relevant to the Respondent's application to re-open its case are set out in section 73 of the Administrative Decisions Tribunal Act 1997 ("the ADT Act"). Section 73 provides:
" 73 Procedure of the Tribunal generally
(1) The Tribunal may, subject to this Act and the rules of the Tribunal, determine its own procedure.
(2) The Tribunal is not bound by the rules of evidence and may inquire into and inform itself on any matter in such manner as it thinks fit, subject to the rules of natural justice.
(3) The Tribunal is to act with as little formality as the circumstances of the case permit and according to equity, good conscience and the substantial merits of the case without regard to technicalities or legal forms.
(4) The Tribunal is to take such measures as are reasonably practicable:
(a) to ensure that the parties to the proceedings before it understand the nature of the assertions made in the proceedings and the legal implications of those assertions, and
(b) if requested to do so-to explain to the parties any aspect of the procedure of the Tribunal, or any decision or ruling made by the Tribunal, that relates to the proceedings, and
(c) to ensure that the parties have the fullest opportunity practicable to be heard or otherwise have their submissions considered in the proceedings.
(5) The Tribunal:
(a) is to act as quickly as is practicable, and
(b) is to ensure that all relevant material is disclosed to the Tribunal so as to enable it to determine all of the relevant facts in issue in any proceedings, and

22I am satisfied that section 73 of the ADT Act gives the Tribunal the discretionary power to allow a party to re-open his or her case, even after the hearing has concluded and the Tribunal's decision has been reserved, provided it does so in accordance with equity, good conscience and the substantial merits of the case. For a discussion of various relevant authorities see French v Sydney Turf Club Ltd [2002] NSWADT 24 and Z v University of A, Dr D and B (No 6) [2003] NSWADT 260.
23The question of whether a party should be permitted to re-open its case to adduce further evidence is essentially one for the discretion of the Tribunal. The guiding principle in determining whether to grant an application for leave to re-open is whether the interests of justice are better served by allowing or rejecting the application as the case may be: Urban Transport Authority of NSW v Nweiser (1992) 28 NSWLR 471 per Clarke JA at 478.
24In the High Court decision in Smith v New South Wales Bar Association [1992] HCA 36; (1992) 176 CLR 256 Brennan, Dawson, Toohey and Gaudron JJ stated at paragraph [32]:
" 32. It is again necessary to distinguish between the considerations which may bear on a decision to re-open and the processes involved in reconsideration once a case has been re-opened. If an application is made to re-open on the basis that new or additional evidence is available, it will be relevant, at that stage, to enquire why the evidence was not called at the hearing. If there was a deliberate decision not to call it, ordinarily that will tell decisively against the application (7) Barker v. Furlong (1891) 2 Ch 172, at p 184; Hughes v. Hill (1937) SASR 285, at p 287. But assuming that that hurdle is passed, different considerations may apply depending on whether the case is simply one in which the hearing is complete (8) As, for example, in Watson v. Metropolitan (Perth) Passenger Transport Trust (1965) WAR 88; Murray v. Figge (1974) 4 ALR 612. or one in which reasons for judgment have been delivered (9) As, for example, in In re Scott and Alvarez's Contract (1895) 1 Ch 596. It is difficult to see why, in the former situation, the primary consideration should not be that of embarrassment or prejudice to the other side (10) As suggested by Sheppard J. in Joyce v. G.I.O. (N.S.W.) reported in Ritchie's, op cit, vol.2, pp 8551-8552. But cf. Watson v. Metropolitan (Perth) Passenger Transport Trust; Murray v. Figge; Hughes v. Hill. In the latter situation the appeal rules relating to fresh evidence may provide a useful guide as to the manner in which the discretion to re-open should be exercised. But those considerations bearing on re-opening are not decisive of the question whether, a matter having been re-opened by reason of error, further evidence can be called.
25The principles were more recently discussed in N M Rural Enterprises Pty Ltd v Rimanui Farms Ltd [2011] NSWSC 1561 at paragraphs [24] - [28].
26In French v Sydney Turf Club Ltd, at paragraph [43], the Tribunal listed a number of relevant factors that it considered should be taken into account when exercising the discretion to re-open a party's case, in circumstances where the hearing has concluded but the Tribunal's decision is reserved. The Tribunal stated:
43 Based on the decided cases and s 73 of the Tribunal Act, we consider that relevant factors to take into account in the exercise of the Tribunal's discretion to re-open a party's case, in circumstances where the hearing has concluded but the Tribunal's decision is reserved, include:
-The nature and relevance of the proposed additional evidence.
-The extent to which it could affect the outcome of the case.
-Whether the evidence is important or peripheral to the main issues in the case.
-The reasons why it was not presented at the hearing (if known) eg, whether it was overlooked, the result of error or misunderstanding, or a deliberate tactical decision.
-The nature and extent of the surprise, embarrassment and prejudice (if any) to the opposing party.
-Whether additional costs would be incurred by the opposing party. If so, to what extent.
-Whether reception of the evidence would unduly prolong proceedings and / or require witnesses to be recalled or new evidence to be gathered by the opposing party.
-The extent to which fairness and the interests of justice would be better served by allowing or rejecting the evidence.
27As noted above, the evidence that the Respondent seeks to adduce is in regard to the issue of whether the Applicant has control over the Range Danger Area. In my view that issue is fundamental to the outcome of the case. It is not merely peripheral to the main issues. A "permissive shooting rights" letter is relevant to that issue in that it would clarify the extent of the Applicant's access to and control over the Range Danger Area.
28The Respondent's explanation for why the evidence was not presented during the course of the hearing is not strong. However, there is nothing to suggest that the Respondent failed to present the evidence at the hearing because of a deliberate tactical decision. It contends that the evidence was not available at that time.
29It is common ground that the Respondent raised the issue of the Applicant's control of the Range Danger Area in September 2012. It was therefore open to the Respondent to adduce evidence prior to the hearing in December 2012. Similarly, it was open to the Applicant to adduce evidence in regard to its compliance with clause 86(3)(d) of the Regulation.
30I accept that some embarrassment and prejudice would flow to the Applicant if the Respondent were granted leave to reopen its case. It would prolong proceedings and this would have consequences for the Applicant at both a financial level and at the practical level of its ability to remain in operation.
31If the Respondent is not granted leave to reopen its case, the potential exists for further action to be taken against the Applicant's range approval on the basis of its assertion of non-compliance with clause 86(3)(d) of the Regulation. In my view, the need for finality is best addressed by allowing the application.
32I accept that the Applicant's ability to obtain a permissive shooting rights letter from Air Services Australia is affected but I do not agree that any opportunity do so is necessarily fatally prejudiced. I am not aware that negotiations between the Applicant and Air Services Australia have been exhausted in that regard.
33In my view, compliance with clause 86(3)(d) of the Regulation is fundamental to the public interest in ensuring public safety. If the Respondent were granted leave to reopen its case the Applicant would have an opportunity to respond to the issue of its compliance with the clause. It could also further explore the question of its ability to obtain a permissive shooting rights letter from Air Services Australia.
34In my view, the interests of justice are better served by allowing the application so that these issues can be further addressed.
35In order to ensure that the time needed to finalize the matter is minimised, the parties are invited to attempt to agree on a timetable for the further progress of the matter. If that is not possible, the matter will be listed for further Directions Hearing on 8 August 2013 at 9.30am.
