The nature of the application and factual background.
1 By its amended application, the applicant, the Construction, Forestry, Mining and Energy Union ("the CFMEU"), seeks by way of interlocutory relief the following injunctions:
"1. An injunction that the employers by themselves, their servants or agents be restrained until the determination of this Application, or further order from taking or threatening to take any action to institute or continue any proceeding relating to the industrial action taken in the interlocutory period (or directing, procuring, advising, authorising, suggesting or encouraging any other person to take or threaten to take any such action).
2. An injunction that the employers by themselves, their servants or agents, be restrained until the determination of this Application, or further order, from:
(a) threatening to commence or commencing any proceedings against the Applicant, its officers, employees or members relating to the industrial action taken in the interlocutory period; and
(b) threatening to commence or commencing any proceedings against the Applicant, its officers, employees or members claiming damages or injunctive relief relating to the industrial action taken in the interlocutory period; and
(c) taking any further steps in relation to any such proceeding already commenced at the date of this application.
3. An injunction that the Respondents by themselves, their servants or agents, be restrained until the determination of this Application, or further order, from initiating any court action against the applicant, concerning any industrial action taken by the applicant between the date of the determination of the application for interlocutory relief and the date of the determination of this application, without first giving the Applicant 48 hours written notice of intent to initiate that action and enclosing with that written notice a copy of any draft court documents relating to such action.
4. An injunction restraining the employers by themselves, their servants or agents until the determination of this Application or further order from taking any further step in the proceeding commenced by the employers in the Supreme Court of Victoria against the Applicant, being proceeding number 4377 of 2000 ("the Supreme Court action").
5. An injunction restraining the employers by themselves, their servants or agents until the determination of this Application or further order from commencing any proceedings in relation to matters referred to in paragraphs 1 and 2 of the Indorsement of the Writ in the Supreme Court action.
6. An injunction restraining the First Respondent by itself, its servants or agents until the determination of this Application or further order from
(a) taking or threatening to take any action to prevent subcontractors engaged on its sites from offering overtime to members of the Applicant who are employed by those subcontractors (or directing, procuring, advising, authorising, suggesting or encouraging any other person to take or threaten to take any such action); or
(b) by threats promises or otherwise, encouraging subcontractors to stand down or otherwise injure or prejudice the position of the employees of the subcontractors."
2 The CFMEU is presently a party to the National Building and Construction Industry Award 1990 ("the Award") made by the Australian Industrial Relations Commission ("the Commission"). The CFMEU is also a party to enterprise agreements, one with the first respondent, Mirvac Constructions Pty Ltd ("Mirvac"), the nominal expiry date of which is 30 November 2000, another with the second respondent, CDK Tectonics Ltd ("CDK") which nominally expired on 30 November 1999 and a third with the third respondent, Construction Engineering (Aust) Pty Ltd ("Construction Engineering") which nominally expired on 30 November 1997. The CFMEU has also, since 1997, entered into certified agreements with more than 2,500 sub-contractors in the building and construction industry. The great majority of those agreements passed their nominal expiry dates on or before 30 November 1999.
3 In December 1999, the CFMEU served notices under s 170MI of the Workplace Relations Act 1996 ("the Act") on those employers who were parties to certified agreements which had passed their nominal expiry date. Each notice purported to initiate a bargaining period seeking to achieve a certified agreement providing for, amongst other things, wage increases of 8 per cent per year over the nominal life of the proposed new agreement to 30 September 2002, a limitation on overtime, increased superannuation and a 36 hour week to be worked over a nine day fortnight.
4 Officials of the CFMEU have had frequent meetings with representatives of the Master Builders Association of Victoria ("MBAV") and the Construction Employers Planning Forum ("CEPF") from October 1999 to February 2000 in the course of negotiations about the claims set out in the notices under s 170MI. This paragraph occurs in an affidavit of 1 March 2000 by Toby Borgeest, a solicitor for the CFMEU:
"I am informed by Martin Kingham that, prior to the meeting which took place on 28 January 2000, he had conversations with a number of officials from at least four of the members of the CEPF. Those company officials advised Kingham that the strategy of all of the CEPF members would be to obtain orders for damages against the CFMEU, and use those orders as leverage to make the CFMEU back off in its claim for a 36 hour week. I am informed by Kingham and believe that these conversations which he had were conversations on a confidential basis with the officials referred to. Kingham is accordingly reluctant to reveal the names of those officials for fear of retribution which may be directed towards them."
5 On 5 January 2000, the CFMEU issued notices under s 170MO of the Act which were served on Construction Engineering and certain sub-contractors. Each of those notices was in the following form:
"RE: Section 170MR of the Workplace Relations Act 1996
In accordance with the above mentioned provision, we hereby put you on notice that industrial action will be taken against your company for the purpose of securing a certified agreement under Part VIB of the Workplace Relations Act 1996.
The industrial action will occur as follows:
Commencing on 11th January 2000 officers, employees and members of the union (as appropriate) will engage in industrial action by
(a) holding a stopwork meeting, and then
(b) imposing one or more of the following forms of ban or limitation on the performance of work, in rolling sequence:
(i) refusal to work overtime
(ii) work to rule or award, including strict adherence to break times
(iii) refusal to operate cranes
(iv) refusal [sic] operate excavators
(v) refusal to operate scissor lifts
(vi) bans on erection of formwork and placement of concrete
(vii) bans on painting, carpentry, non-trades work
(viii) ban on ladders
(ix) ban on mobile scaffolds refusal to perform any work at all every second Monday from the second Monday in February."
6 As foreshadowed in the notice of 5 January 2000, members of the CFMEU have taken industrial action against employers on whom the notices were served. On 14 February 2000, the CFMEU issued further notices under s 170MO which were again served on Construction Engineering and various sub-contractors. The new notices foreshadowed more extensive industrial action than that described in the earlier notices. That industrial action, it was intimated, would commence on 21 February 2000. Each of the new notices concluded with this notation:
"Please note: If your company has
(a) Already signed an interim industrial agreement with CFMEU or
(b) Has an unexpired certified agreement with CFMEU
please ignore this notice."
7 As contemplated by the later notices under s 170MO, members of the CFMEU have, since 21 February 2000, taken industrial action which the CFMEU contends is "protected action" within the meaning of s 170MT of the Act.
8 On 22 February 2000, a writ was issued out of the Supreme Court of Victoria at the instance of Mirvac, CDK and Construction Engineering. It seems that a draft copy of each of that writ, an indorsement of claim, a summons requiring attendance on an application by the plaintiffs for interlocutory relief and various affidavits in support was served on the CFMEU at its FEDFA divisional branch office. On the same day, Beach J in the Supreme Court made the following ex parte orders in the plaintiffs' action, which was later instituted as 4373 of 2000:
"Upon the Plaintiffs by their Counsel undertaking:
(a) to abide by any order as to damages in case the Court should hereafter be of opinion that the Defendant shall have sustained any by reason of this Order which the Plaintiffs ought to pay; and
(b) to issue a Writ and Indorsement and Summons in the terms annexed forthwith.
THE COURT ORDERS:
1. Until 4.30pm on 24 February 2000 or further Order, the Defendant (whether by its officers, delegates, servants, agents or howsoever otherwise) be restrained from directing, procuring, advising, authorising and/or encouraging its members (otherwise than in the exercise of the rights which the Defendant has pursuant to Division 8 of Part VIB of the Workplace Relations Act 1996) not to perform the work which their contracts of employment (with any of the Plaintiffs or with any sub-contractor engaged on the Plaintiffs' sites) required them to perform.
2. The Defendant:

7. Service of a copy of this Order by facsimile be deemed proper service.
8. The further hearing of the Summons annexed hereto be adjourned to 10.30 am, 24 February 2000."
9 In the afternoon of 22 February, North J in this Court ordered that paragraphs 1 and 2 of the orders of Beach J be stayed until 4.30 pm on 24 February 2000 upon the CFMEU by its Counsel undertaking to file and serve, within the time limited by the Rules, a notice of appeal against those orders. On 24 February 2000, the plaintiffs in the Supreme Court action sought from Beach J the following orders:
"1. Until further Order, the Defendant (whether by its officers, delegates, servants, agents or howsoever otherwise) be restrained from directing, procuring, advising, authorising and/or encouraging its members not to perform the work which their contracts of employment (with any of the Plaintiffs or with any sub-contractor engaged on the Plaintiffs' sites) require them to perform.
2. The Defendant:
(1) prepare a letter on the Defendant's letterhead signed by the State Secretary of the Defendant's Victorian Branch to send forthwith by ordinary pre paid mail a letter to the home address of each of its members employed by the Plaintiffs or working on the Plaintiffs' sites in the terms of the attached letter informing those members of the terms of this order and directing that they forthwith cease industrial action and perform the work which their contracts of employment require; and
(2) to send a copy of one of the letters to the solicitors for the Plaintiffs, at facsimile no. 9230 0505, marked to the attention of Ross Levin, by 5.00 pm on 25 February 2000.
3. The Defendant (whether by its officers, delegates, servants or agents or howsoever otherwise) is hereby restrained, until the hearing and determination of this matter or further order, from commencing, continuing or taking any step in any proceeding or action in the Federal Court of Australia, which has the effect or may have the effect of:
a) restraining or restricting the Plaintiffs from commencing, continuing or taking any step in this proceeding; or
b) restraining or restricting the Plaintiffs from continuing or taking any step in respect of any Application filed by them pursuant to section 166A of the Workplace Relations Act 1996 (Cth); or
c) restraining or restricting the Plaintiffs or sub-contractors working on the Plaintiffs' sites from commencing, continuing or taking any step in proceedings involving the industrial action the subject of this proceedings; or
d) restraining or restricting the Plaintiffs or sub-contractors working on the Plaintiffs' sites from commencing, continuing or taking any steps in proceedings involving industrial action affecting the Plaintiffs.
4. The Defendant is hereby restrained from making any application for a stay of this order other than an application in accordance with the Supreme Court (General Civil Procedure) Rules 1996."
10 In the result, Beach J declined to make any interlocutory orders and the interim orders which he had made on 22 February ceased to have effect at 4.30 pm on 24 February.
11 In the meantime, on 22 February 2000, Mirvac, CDK and Construction Engineering had given notice, pursuant to s 166A of the Act, of their intention to commence an action in tort against the CFMEU "in respect of all or any conduct or industrial action at all on any of the Sites listed in Schedule B from 1 December 1999 which was or is organised, procured, directed, encouraged, induced, engaged in or incited by" the CFMEU.
12 A hearing of the application under s 166A took place in the Commission on 25 February and, on 1 March, Commissioner Tolley issued a Certificate in these terms:
"Under subsection 166A(6)(C) of the Workplace Relations Act 1996, I hereby certify that the Commission has not stopped the conduct to which the notice dated 22 February 2000 relates and that 72 hours has passed since the notice was given under subsection 166A(3) in respect of that conduct.
This certificate has effect from 1 March 2000."
13 The CFMEU contends that by the actual institution of proceedings in the Supreme Court and by holding out the prospect of an action in tort foreshadowed by the application under s 166A, Mirvac, CDK and Construction Engineering have sought to coerce the CFMEU not to negotiate or make agreements under Part VIB of the Act. That conduct, it is said, contravenes s 170NC which provides, so far as is relevant:
"(1) A person must not:
(a) take or threaten to take any industrial action or other action; or
(b) refrain or threaten to refrain from taking action;
with intent to coerce another person to agree, or not to agree, to:
(c) making, varying or terminating, or extending the nominal expiry date of, an agreement under Division 2 or 3; or
(d) approving any of the things mentioned in paragraph (c).
(2) Subsection (1) does not apply to action, or industrial action, that is protected action (within the meaning of Division 8)."
14 Some evidence of the requisite intent is said to be afforded by a statement attributed by "Australian Current Law News" of 15 February 2000 to Lawrie Cross of the MBAV, which was representing CDK and Construction Engineering in an application to the Commission for the suspension of various bargaining periods initiated by the CFMEU. That statement attributed to Mr Cross was to the effect that "the threat of legal action might bring the CFMEU back to the negotiating table" and, as reported by "Australian Current Law News", was apparently made immediately after Marshall J pronounced his judgment in Construction Forestry Mining and Energy Union v Multiplex Constructions Pty Ltd [2000] FCA 101, which is discussed in para 23 below of these reasons. Mr Cross has sworn an affidavit denying having made a statement to that effect and further affidavits have been filed on behalf of each of the respondents denying that he or the MBAV had been authorised to make any such statement on behalf, respectively, of Mirvac, CDK or Constructions Engineering.
15 In addition, the CFMEU has adduced evidence that Mirvac had intimated that it would deny access at weekends to one of its sites in South Yarra to a sub-contractor, J Z Lee Interiors Pty Ltd, which had reached agreement with the CFMEU to avert industrial action on either side and would thereby prevent employees of that sub-contractor from working overtime. That allegation has been denied by the Mirvac site manager alleged to have made the statement. He has deposed that the site was, in fact, open to sub-contractors on Saturday 26 February and has only been closed on about eight Saturdays for purely economic reasons referable to insufficient requests by sub-contractors to be allowed to work.
