The formal requirements for joinder and addition of parties
6 There is provision in the Federal Court Rules to join two or more parties as respondents in any proceeding (O 6 r 2). That rule provides as follows:
"Two or more persons may be joined as applicants or respondents in any proceeding -
(a) where -
(i) if a separate proceeding were brought by or against each of them, as the case may be, some common question of law or of fact would arise in all the proceedings; and
(ii) all rights to relief claimed in the proceeding (whether they are joint, several or alternative) are in respect of or arise out of the same transaction or series of transactions; or
(b) where the Court gives leave so to do."
7 There is also provision in the rules to add to an existing proceeding any additional party, whether applicant or respondent. Order 6 rule 8 provides:
"(1) Where a person who is not a party -
(a) ought to have been joined as a party; or
(b) is a person whose joinder as a party is necessary to ensure that all matters in dispute in the proceeding may be effectually and completely determined and adjudicated upon,
the Court, on application by him or by any party or of its own motion, may order that he be added as a party and make orders for the further conduct of the proceeding.
(2) A person shall not be added as an applicant without his consent."
8 The first issue to be determined is whether the proposed joinder of the bank as a respondent and its addition as a party to these proceedings can satisfy the formal criteria set out in O 6 r 2 and O 6 r 8 respectively.
9 In my view, the requirements of O 6 r 2, as explained by Lord Wright MR in Bendir v Anson [1936] 3 All ER 326, are satisfied in relation to the proposed joinder of the bank. Common questions of fact would arise in both proceedings if a separate action were to be brought by the applicants against the bank. These common questions of fact revolve around Mr Green's role in having misappropriated monies held on trust for the fifth and sixth applicants from trust accounts opened in the name of the firm.
10 I am also of the view that all rights to relief which would be claimed in the proceeding are "in respect of or arise out of the same transaction or series of transactions". The meaning of this requirement has been authoritatively explained in Birtles v Commonwealth [1960] VR 247, and again in Payne v Young (1980) 145 CLR 609. There are clear links between the proceedings which the applicants have instituted against the NAB and the firm, and the case which they seek to bring against the bank. The common thread between these cases is the alleged misuse of the applicants' funds, first by Mr Green having withdrawn them from the bank without authority and second, by his having concealed and later misappropriated them, utilising the NAB as the vehicle for implementing his criminal plan.
11 In relation to O 6 r 8 (the proposed addition of the bank as a party to the proceedings), I have come to the view that it is necessary, in order to ensure that all matters in dispute in the proceedings may be effectually and completely determined, that the bank be added as a party. That course will avoid the need for the applicants to institute separate proceedings against the bank, with the likelihood of cross-claims of various sorts, leading to a multiplicity of proceedings, and extra cost and delay. It will also avoid the risk of there being divergent results on essentially the same facts.
12 The principles which govern the proper construction of O 6 r 8 are to be found set out in the judgment of the New South Wales Court of Appeal in Qantas Airways Ltd v AF Little Pty Ltd [1981] 2 NSWLR 34 and in particular at 38 per Glass JA. His Honour there made it clear that the expression "all matters in dispute in the proceedings" should not be construed as being limited to those matters arising on the existing pleadings, but rather as including those disputed issues of fact which are "subjacent" to, or which underlie, those pleadings. See also Vandervell Trustees Ltd v White [1971] AC 912 (based on the English precursor to the present rule).
13 In my view, the claims which the applicants have foreshadowed against the bank can properly be regarded as being "subjacent" to the pleadings, as they stand, in the proceedings against the NAB and the former partners of the firm.
