Secondly, it is clear that from Meagher, Gummow and Lehane op cit at 590, par2168, that courts will not be prepared to preserve the status quo if there be involved some countervailing disadvantages which more than equal the desirability of stability. The authors there cite Hubbard v Vosper [1972] 2 Qd 84 at 96, where Lord Denning MR emphasised the importance on an application for an interlocutory injunction for the court to look at the whole of the case and for the remedy to be kept flexible and discretionary. In my opinion, to restrain the Court from examining the realities of the Land as it is at the date of this application would be to deny the true discretionary character of the remedy sought and to limit the Court in a most inappropriate way.
Thirdly, in the circumstances of the present case there is no room for a finding that the steps taken by the second respondent since the interim application are steps taken solely to secure benefit to it. In the report of the applicants' expert Dr K R J Smettem, dated 28 August 1995, agreement was expressed by him that earth works were required to stabilise the gullies on the Land and that this work needed to be completed before the wet season. The applicants' expert Dr W Martinick, in a report dated 21 September 1995, opined that if further development for irrigation purposes were halted, then alternative soil conservation measures should be implemented prior to commencement of the wet season. It was common ground at the interim application that, if the wet season came and no steps were taken, very significant erosion could occur to the Land. Completion of development toward irrigated agricultural Land was one way in which erosion would be prevented. This is not a case where the applicants were unaware of the intention of the second respondent to embark upon that course of action to avoid erosion as a consequence of the wet season. In my opinion these circumstances do not come within the ambit of the policy objection raised by the case for the applicants.
Fourthly, the dictum of Lord Diplock is subject to the qualification that the status quo is to be determined on the facts pertaining to the period immediately preceding the motion for an interlocutory injunction "if there be unreasonable delay between the issue of the writ and the motion for an interlocutory injunction". Following the interim application on 3-4 August 1995, the applicant obtained the reports of Dr Smettem and Dr Martinick on 28 August 1995 and 21 September 1995. Their reports were exchanged and mutual comment was complete by 22 September 1995. On 13 October 1995 three of the applicants filed affidavits and Dr Smettem filed a further affidavit. The motion for interlocutory relief was filed on 27 October 1995. Although it is the case that Lord Diplock considered the period of delay must be more than minimal, it is relevant to have in mind that, with knowledge of the wet season approaching in December, the motion for interlocutory relief was not filed until almost 3 months following the interim application and 1 month prior to the commencement of the wet season. Given that the applicants had knowledge of the intentions of the second respondent in relation to the Land and given that the case for the applicants through their expert reports was based upon taking alternative erosion steps, it seems to me that the time taken by the applicants to pursue the motion for interlocutory relief was unreasonable in all these circumstances.
For these reasons, I do not accept the submission for the applicants that the relevant status quo for this application is that which existed at the time of the interim application on 3-4 August 1995. In my view this conclusion is supported by reference to Spry Equitable Remedies 4th ed (1990) at 447.
I accept the submission for the applicants that the approach of the Court on this application is not just to consider whether new facts have come into existence since the interim application and to regard the applicants as under an onus to produce cogent and compelling evidence to demonstrate that the factual circumstances have altered such that the balance of convenience now favours the grant of an injunction: Adam P Brown Male Fashions v Phillip Morris Inc (1981) 148 CLR 170 at 178. In my opinion it is necessary for the Court on this application to examine all admissible evidence without reference to any such onus, particularly as the interim
application was decided on the basis that evidence was then incomplete.
Serious question to be tried
The principles upon which the Court should exercise its discretion pursuant to s23 of the Federal Court of Australia Act 1976 to grant or refuse interlocutory relief are not in dispute. They require that the Court be satisfied that there is a serious question to be tried and determine where the balance of convenience lies: Castlemaine Tooheys Ltd v State of South Australia (1986) 161 CLR 148. These factors are not independent of each other - in considering whether to grant an interlocutory injunction the Court must have regard to the strength of the applicant's claim: Bullock v Federated Furnishing Trades Society of Australasia (1985) 60 ALR 235 at 241, applied in O D Transport Pty Ltd v WA Government Railways Commission (1986) 71 ALR 190 at 193. The authorities direct special attention to the strength of the case of an applicant where the practical effect of an interlocutory injunction would be to finally determine the issue and where mandatory interlocutory injunctions are sought: Sabre Corporation Pty Ltd v Laboratories Pharm-a-Care Pty Ltd (1995) ATPR 4378 at 4382-4. In the argument on the present application it was not contested that regard should be had to the strength of the applicants' case. The onus in respect of both the serious question and the balance is on the applicant: Castlemaine Tooheys (supra); O D Transport (supra).
The claim which the applicants seek to assert is one for native title pursuant to an Application for Determination of Native Title lodged under the Native Title Act ("NTA"). By virtue of s22 of that Act, subject to ss24 and 25, an "act" which is an "impermissible future act" is invalid to the extent that it "affects" native title. An act "affects" native title if it extinguishes the native title rights and interests or if it is otherwise wholly or partly inconsistent with their continued existence, enjoyment or exercise: NTA, s227.
The applicants' claim that the past conduct of the second and third respondents and the future conduct of the first, second and third respondents in relation to the Land will in each case comprise impermissible future acts under the NTA. It is claimed by them that such acts are invalid and that, if they are not injuncted, by their nature they may extinguish the applicants' native title rights and interests.
The native title rights which the applicants assert, as appears from the affidavits of three claimants on this application, assert a usage in relation to the Land for (a) hunting native fauna; (b) gathering sustenance from native flora; (c) crossing the Land or using the Land as access when travelling to other important country north of Kununurra in respect of which the applicants assert they have native title; and (d) using the Land with other traditional country in order to teach their children about Aboriginal culture. It is not disputed for the purposes of the present proceeding that such usages could constitute native title if established and not extinguished. Findings are not now necessitated on whether categories (a) and (b) overlap with category (d) and whether the former categories involve a usage which occurs on the Land only in conjunction with adjacent land.
On behalf of the first, second and third respondents it is not disputed that there is a serious question to be tried. That much is apparent from the progress of Action 6001 in which the principal issue is whether the native title rights claimed by the applicants have been extinguished by the grant of pastoral leases in the area under claim.
The submissions for the first, second and third respondents do, however, go to the question of the strength of the case to be tried. The respondents contend that, if it is established that the applicants held native title rights over the Land, these have been extinguished by reason of the history of the pastoral lease tenure of the Land, the resumption of the Land for the Ord River Project and acts in pursuance of that project. These contentions are made in reliance on Mabo v Queensland (No2) (1992) 175 CLR 1 where it was held that native title could be extinguished by legislative or executive actions of State Governments, provided they carried a clear and plain intention or clear unambiguous words designed to extinguish native title: Brennan J (as he then was) at 64. At 69 he said:
"Where the Crown has validly alienated land by granting an interest that is wholly or partially inconsistent with a continuing right to enjoy native title, native title is extinguished to the extent of the inconsistency."
