Order 15 r 15 of the Federal Court Rules
Under Order 15 r 15 the applicant for an order for discovery bears the onus of satisfying the Court that the order is "necessary". What is the significance of the word "necessary" in the rule (the rule is in the same terms, mutatis mutandis, as Part 23 r 14 of the Rules of the Supreme Court of New South Wales)? The answer must depend upon the purpose properly served by the procedure of discovery of documents.
What must be discovered are "documents relating to any matter in question ... " in the proceedings; see Order 15 rr 2 (2) (a) and 8. The "matters in question" in the proceedings are the issues as revealed by the pleadings. It is well established that it is not necessary in order for a document to "relate" to such a matter that it be admissible in evidence in relation to that matter, and that it suffices that the document may lead to a train of inquiry which may advance the case of one party or damage that of his adversary: see, for example, Compagnie Financiere et Commerciale du Pacifique v Peruvian Guano Co (1882) 11 QBD 55 (CA) at 60 (Baggallay LJ), 62-64 (Brett LJ); Mulley v Manifold (1959) 103 CLR 341 (Menzies J) at 345; Commonwealth of Australia v Northern Land Council (1993) 176 CLR 604 at 632 (Toohey J).
In my opinion, Order 15 r 15 requires that the Court be satisfied that an order of the kind referred to in that rule is, at the time when the order is made, necessary "in the interests of a fair trial": Percy v General Motors-Holden's Pty Ltd [1975] 1 NSWLR 289 (NSW/Rath J) at 292E,F. Similarly, in the judgment of Cross J in Boyle v Downs [1979] 1 NSWLR 192, in which his Honour had to construe a similarly expressed constraint in Part 24 sub-r 5 (2) of the New South Wales Supreme Court Rules relating to interrogatories, the following passage appears:
"Of course, in many cases the evidentiary difficulties of one party only, i.e. the moving party, may loom large as considerations; but the test is not solely a matter of how much more effectively the moving party can present his case but, I believe, whether, all in all, the order is reasonably necessary for the disposing fairly of the case; and where a plaintiff has evidentiary difficulties, considerations of those difficulties will probably be the most important, but not the only, considerations relevant to determining whether the order is so necessary. I feel that it is for the reason that the rule should take into account the interests of both parties that the rule in other places, e.g. England and South Australia, is framed to make the relevant test 'necessary for the disposing fairly of the cause or matter'. I am of the opinion that the word 'necessary' in r.5 (2) should be interpreted in a somewhat similar manner, namely, 'reasonably necessary for the disposing fairly of the cause or matter'. In considering the meaning of the word 'necessary' in Pt. 23, r.14 -- a rule relating to discovery and inspection similar to r.5 in Pt.24 relating to interrogatories -- Rath J. in Percy v General Motors-Holden's Pty Ltd. [[1975] 1 N.S.W.L.R. 289, at p.292.] interpreted it as 'necessary in the interests of a fair trial'. This definition is similar to the one I have suggested; for in Griebart v Morris [[1920] 1 K.B. 659, at p.666.], Scrutton L.J. interpreted 'necessary for disposing fairly of the cause or matter' (under the English rules relating to interrogatories) as 'necessary for the fair trial of the action'." (at 205C-E - emphasis supplied)
The notion of the "interests of a fair trial" and of the "fair disposition of a case" encompasses, in my view, the opening up of a train of inquiry of the kind referred to above which is part of the proper function of discovery.
In a case such as this, where one party and not the other is likely to have documents relating to a matter in question, it seems to me to be prima facie "necessary" in the sense referred to that discovery be ordered. But this general position is subject to the well established exception that discovery should not be ordered to enable a mere "fishing expedition" (see below).
In the present case, the s 155 notices addressed to the respondents required production of only documents "wherein any reference is made to" the Meeting, the Special Fee agreement and the UTFs agreement, the invoicing and payment of the Special Fee and the UTFs, and the recipient's preparation and submission of its tender. This description is narrower than that of documents in the possession, custody or power of
Concretes, Multiplex and/or Leightons "relating to any matter in question" in the proceedings. There may be documents in the possession, custody or power of the respondents fitting that broader description which do not contain "references to" the things mentioned.
A particular advantage of discovery is that the party required to give it must search for documents by reference to a judgment which that party is required to make and is in a position to make. This process is apt to bring to light documents the existence of which will often be beyond the other party's knowledge. The Commission is not in a position to know what documents are in the respondents' possession, custody or power.
Subject to what I say below in relation to discretion, I am satisfied that it is necessary in the interests of fair disposition of the proceedings that discovery be ordered.
