Relevant principles
25 Rule 7.23 of the FCR is the counterpart of O 15A r 6 in the Federal Court Rules 1979 (Cth). However, as counsel for OBS noted, there are two important differences:
(a) rule 7.23 requires that the prospective applicant have a reasonable belief. That is to say, the test is now both subjective and objective - the prospective applicant must itself hold a belief and that belief must, objectively speaking, be reasonable; and
(b) the documents which the Court may order the prospective respondent to discover to the prospective applicant are only those which are "directly relevant to the question whether the prospective applicant has a right to obtain the relief".
26 The elements of the entitlement to preliminary discovery for which r 7.23 provides are:
(a) the prospective applicant believes that it may have the right to obtain relief in this Court from a prospective respondent (subr (1)(a));
(b) that belief is reasonable (subr (1)(a));
(c) the prospective applicant has made reasonable inquiries with a view to obtaining sufficient information to decide whether to start a proceeding in the Court to obtain that relief (subr (1)(b);
(d) having made those inquiries, the prospective applicant still lacks sufficient information to make the identified decision (subr (1)(b)):
(e) the prospective applicant believes that the prospective respondent has or has had, or is likely to have or have had, documents in its control which are directly relevant to the question of whether the prospective applicant has a right to obtain the relief (subr (1)(c)(i));
(f) that belief is reasonable (subr (1)(c)(i));
(g) the prospective applicant believes that its inspection of the documents of the prospective respondent would assist it in making the decision (subr (1)(c)(ii)); and
(h) that belief is reasonable (subr (1)(c)(ii).
27 Each of these elements must be satisfied. Even when they are, the Court retains a discretion to refuse to make the orders (r 7.23(2)).
28 The prospective applicant must provide evidence to establish its own subjective belief of elements (a), (e) and (g) (EBOS Group Pty Ltd v Team Medical Supplies Pty Ltd (No 3) [2012] FCA 48; (2012) 199 FCR 533 at [28]-[32]) and point to material indicating that its belief about each of those matters is reasonable.
29 The elements listed above have now been discussed in numerous authorities, including Quanta Software International Pty Ltd v Computer Management Services Pty Ltd [2000] FCA 969, (2000) 175 ALR 536 at [36]; Reeve v Aqualast Pty Ltd [2012] FCA 679 at [66], and the principles concerning their application are settled. A detailed review of the authorities is not necessary for the disposition of the present application. It is, however, convenient to refer to Pfizer Ireland Pharmaceuticals v Samsung Bioepis AU Pty Ltd [2017] FCAFC 193; (2017) 257 FCR 62 in which the Full Court addressed matters bearing on the belief required of the prospective applicant. Allsop CJ said, at [8], of r 7.23(1)(a):
… The foundation of the application in r 7.23(1)(a) is that an applicant (a person or a corporation) reasonably believes that he, she or it may have a right to relief. The belief therefore must be reasonable (expressed in the active voice that someone reasonably believes) and it is about something that may be the case, not is the case. It is unhelpful and likely to mislead to use different words such as "suspicion" or "speculation" to re-express the rule …

30 To similar effect, Perram J (with whose reasons Allsop CJ generally agreed) said at [108]:
As I have noted already, it is not the requirement of this rule that there be a reasonable belief that there is a right to obtain relief. This is an important qualification and it colours necessarily the analysis involved in assessing the reasonableness of the belief. FCR 7.23(1) is not about giving preliminary discovery to those who believe they do have a case. Its wording unequivocally shows that it is about those who do not know that they have a case but believe that they may. In terms, it authorises what traditionally have been referred to as fishing expeditions; that is to say, evidentiary adventures in which the goal is not to find proof of a case already known to exist, but instead to ascertain whether a case exists at all.
(Emphasis in the original)
31 Following a review of several of the authorities, Perram J noted at [120], the following propositions about the evidence required in applications for preliminary discovery to prove the requisite belief in the first of the identified elements:
(i) the prospective applicant must prove that it has a belief that it may (not does) have a right to relief;
(ii) it must demonstrate that the belief is reasonable, either by reference to material known to the person holding the belief or by other material subsequently placed before the Court;
(iii) the person deposing to the belief need not give evidence of the belief a second time to the extent that additional material is placed before the Court on the issue of the reasonableness of the belief. That belief may be inferred;
(iv) the question of whether the belief is reasonable requires one to ask whether a person apprised of all of the material before the person holding the belief (or subsequently the Court) could reasonably believe that they may have a right to obtain relief; and
(v) it is useful to ask whether the material inclines the mind to that proposition but very important to keep at the forefront of the inclining mind the subjunctive nature of the proposition. One may believe that a person may have a case on certain material without one's mind being in any way inclined to the notion that they do have such a case.
(Emphasis in the original)
32 Perram J went on to elaborate the requirement that the prospective applicant have a belief that it may (and not does) have a right to relief by saying:
[121] In practice, to defeat a claim for preliminary discovery it will be necessary either to show that the subjectively held belief does not exist or, if it does, that there is no reasonable basis for thinking that there may be (not is) such a case. Showing that some aspect of the material on which the belief is based is contestable, or even arguably wrong, will rarely come close to making good such a contention. Many views may be held with which one disagrees, perhaps even strongly, but this does not make such a view one which is necessarily unreasonably held. Nor will it be an answer to an application for preliminary discovery to say that the belief relied upon may involve a degree of speculation. Where the language of FCR 7.23 relates to a belief that a claim may exist, a degree of speculation is unavoidable. The question is not whether the belief involves some degree of speculation (how could it not?); it is whether the belief resulting from that speculation is a reasonable one. Debate on an application will rarely be advanced, therefore, by observing that speculation is involved.
33 In his separate reasons in Pfizer, Nicholas J said, at [170], that r 7.23 requires the prospective applicant to have the requisite belief at the time of making the application. His Honour also suggested at [177] that the prospective applicant must establish a belief going beyond "a mere possibility" that the prospective respondent may have engaged in conduct which, if proven, would entitle the prospective applicant to relief.
34 Finally, in Pfizer both Allsop CJ and Perram J noted that applications for preliminary discovery are summary applications and are not to be conducted as mini-trials, at [2] and [126].
