"It would be wrong to deny a plaintiff resort to the ordinary processes of a court on the basis of a prediction made at the outset of a proceeding if that prediction is to be made simply on a preponderance of probabilities" (at 58).
7 Similarly, in Air Services Australia v Zarb (NSWCA unreported, 26 August 1998) Rolfe AJA found it useful to remind himself of the highly demanding test imposed on a party seeking summary judgment. His Honour referred to Dey v Victorian Railways Commissioners (1949) 78 CLR 62; General Steel Industries Inc v Commissioner for Railways (NSW) (1964) 112 CLR 125 and Webster & Anor v Lampard (1993) 177 CLR 598. I have reproduced some of the passages quoted in Zarb.
8 In General Steel Barwick CJ, who heard the application alone stated at 130:
"Although I can agree with Latham CJ in the same case when he said that the defendant should be saved from the vexation of the continuance of useless and futile proceedings, in my opinion 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. On the other hand I do not think that the exercise of the jurisdiction should be reserved for those cases where argument is unnecessary to evoke the futility of the plaintiff's claim. Argument, perhaps even of an extensive kind, may be necessary to demonstrate that the case of the plaintiff is so clearly untenable that it cannot possibly succeed."
9 Barwick CJ also said at 129:
"It is sufficient for me to say that these cases uniformly adhere to the view that the plaintiff ought not to be denied access to the customary tribunal which deals with actions of the kind he brings, unless his lack of cause of action - if that be the ground on which the Court is invited, as in this case, to exercise its powers of summary dismissal - is clearly demonstrated. 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'."
10 In Webster Mason CJ, Deane and Dawson JJ reinforced the rigorous testing stating, at 602:
"The power to order summary judgment must be exercised with 'exceptional caution' and 'should never be exercised unless it is clear that there is no real question to be tried."'
11 According to Rolfe AJA in Zarb at 15-16:
"The demanding nature of the test is in no way lessened in circumstances where there are the potential for difficult factual and legal issues to arise. Rather, as the decision in Webster made clear, it is heightened: see also Wickstead & Ors v Browne (1992) 30 NSWLR 1 and Esanda Finance Corporation Limited v Peat Marwick Hungerfords (1997) 188 CLR 241."
12 Master Allen (as he then was) in Hospitals Contribution Fund of Australia v Hunt (1982) 44 ALR 365 at 373-374 said:
"…It is not by any means rare in the history of the development of the common law that a high appellate court, in enunciating a novel development in the law, albeit one avowedly based on a miscellany of old cases, has chosen to use general words of imprecise limits in meaning to facilitate the arrival, in later cases, of the final form of the development without the need to overrule what earlier had been stated. That being so I am of opinion that a court at first instance should be particularly astute not to risk stifling that development of the law by summarily throwing out of court actions in respect of which there is a reasonable possibility that it will be found, in the development of the law, still embryonic, that a cause of action does lie. The risk of injustice to the plaintiff, which summary termination of his claim would entail, is real. One cannot predict, with firm assurance, what the future holds as the final formulation of the new development."
