THE PRIMARY JUDGE'S REASONING
7 The primary judge proceeded on the basis that the jurisdiction under O 11 r 16 to strike out a pleading in the defence is to be exercised in accordance with the test articulated in General Steel Industries Inc v Commissioner for Railways (NSW) (1964) 112 CLR 125 at 129:
The test to be applied has been variously expressed; 'so obviously untenable that it cannot possibly succeed'; 'manifestly groundless'; 'so manifestly faulty that it does not admit of argument'; 'discloses a case which the Court is satisfied cannot succeed'; 'under no possibility can there be a good cause of action'; 'be manifest that to allow them' (the pleadings) 'to stand would involve useless expense'.
8 Further at 130:
... great care must be exercised to ensure that under the guise of achieving expeditious finality a plaintiff is not improperly deprived of his opportunity for the trial of his case by the appointed tribunal. ... the exercise of this jurisdiction should [not] be reserved for those cases where argument is unnecessary to evoke the futility of the plaintiff's claim.
9 The primary judge accepted that before a pleading, or any of it, can be struck out summarily, it is necessary that there be a high degree of certainty about the ultimate outcome of the proceeding if it were allowed to go to trial in the ordinary way: John Fairfax Publications Pty Ltd v Hitchcock (2007) 70 NSWLR 484 (at [6]-[7], [29], [106]-[109]).
10 His Honour cited Agar v Hyde (2000) 201 CLR 552, where Gaudron, McHugh, Gummow and Hayne JJ observed (at [57]) that contested issues should not be decided except in the clearest of cases. Their Honours said:
Ordinarily, a party is not to be denied the opportunity to place his or her case before the court in the ordinary way, and after taking advantage of the usual interlocutory processes. The test to be applied has been expressed in various ways (Dey v Victorian Railways Commission (1949) 78 CLR 62 at 91, per Dixon J; General Steel Industries Inc v Commissioner for Railways (NSW) (1964) 112 CLR 125 at 130, per Barwick CJ), but all of the verbal formulae which have been used are intended to describe a high degree of certainty about the ultimate outcome of the proceeding if it were allowed to go to trial in the ordinary way.
11 The primary judge noted the submissions of the Unions that, as the stoppages in December 2009 and January 2010 are part of the same dispute over the nature of the workers' accommodation, (described as 'Motelling'), a full understanding of how important the issue of Motelling was to the Project workers, and the lengths to which they were prepared, and able, to go to oppose its introduction, is necessary for a proper consideration of the events of November and December 2009. The primary judge noted that as part of such consideration, an aspect of the defence sought to be run was that there was strong and persistent motivation, with no involvement by the Unions, on the part of the Project workers to resist the introduction of Motelling.
12 The Unions also contended that the matters in the defence at para 28A would be relevant to mitigation. However, his Honour correctly noted that relevance as to penalty does not provide a warrant for permitting the allegations to remain as a defence to the substantive liability allegations made against the Unions.
13 Despite the commonality of the features of the December and January strikes, the primary judge noted that senior counsel for the Unions disavowed any suggestion that the words 'part of a series of protests instigated and taken by the Project workers over the issue of Motelling between that date (30 November 2009) and 30 January 2010', as found in para 28A, were intended to convey that there was any agreement, arrangement or understanding already reached in November 2009 by the Project workers that they would take further industrial action in January 2010. The primary judge continued (at [26]):
Accordingly the word "series" or "sequence" as was employed in oral argument in relation to para 28A is not used in the sense that the sequence was foreshadowed in November or December 2009. Rather, it is but a reference to the commonality affecting the industrial action in December 2009 and January 2010 to which I have referred. As senior counsel for the applicant put it, it can only be characterised as a sequence looking back from January 2010 but not as at December 2009.
14 The primary judge said (at [32]-[33]):
The factual issues are clearly drawn in these paragraphs of the [statement of claim] and the defence of the Unions. Either the first respondent did and said what is alleged against him, and through him, the Unions, or he did not. Failure to establish those allegations at trial will inevitably mean that the application will fail. The evidence called by the applicant will have to be tested and weighed against that in support of the Unions' pleas at paras 24 and 28 of the defence.
That factual contest cannot logically or rationally and therefore probatively, be aided by proof of those matters pleaded in para 28A of the Unions' defence. A pleading is a means to the achievement not only of procedural fairness but also the efficient use of judicial resources and those of the parties by the identification of what is truly at issue: Australian Competition and Consumer Commission v Craftmatic Australia Pty Ltd at [14]. Paragraph 28A, in my opinion, raises a false issue and therefore does not disclose reasonable grounds for a defence to the allegations in [statement of claim] at paras 24 and 28. This is the case assuming, for present purposes, the correctness of the particulars under para 28A of the defence. It would additionally cause prejudice to the applicant in having to contest a significant false issue and would inevitably introduce unwarranted delay in the resolution of the real issues. The applicant's case as I have mentioned is based upon what it is that Mr McDonald did and said at the 27 and 30 November 2009 meetings. If para 28A were allowed to stand, on the basis asserted, it would potentially open up evidence as to what occurred between the December Strike and the January industrial action relevant to a full appreciation of why that action was taken, none of which it seems, implicitly, from the particulars to the defence at para 28A, concerned or involved Mr McDonald. Indeed separate proceedings have been brought in this Court (WAD 14 of 2010) by various corporate employers against project workers, but not Mr McDonald or the Unions, in relation to alleged unlawful industrial action taken at the same site on 25, 26 and 27 January 2010. It appears this action again concerned Motelling and indeed is the strike action referred to in the defence at para 28A under particulars (c) and (d).
