41 Given the seriousness of allegations such as criminal conduct and other conduct that might attract summary dismissal, a tribunal should not lightly make a finding that, on the balance of probabilities the appellant was guilty of the misconduct alleged. In this context, it is appropriate that we refer to the following passage from Neat Holdings Pty Ltd v Karajan Holdings Pty Ltd (1992) 110 ALR 449 where the High Court observed:
The ordinary standard of proof required of a party who bears the onus in civil litigation in this country is proof on the balance of probabilities. That remains so even where the matter to be proved involves criminal conduct or fraud ((1) See, e.g., Hocking v. Bell (1945) 71 CLR 430, at p 500; Rejfek v. McElroy (1965) 112 CLR 517, at pp 519-521). On the other hand, the strength of the evidence necessary to establish a fact or facts on the balance of probabilities may vary according to the nature of what it is sought to prove. Thus, authoritative statements have often been made to the effect that clear ((2) Briginshaw v. Briginshaw (1938) 60 CLR 336, at p 362; Helton v. Allen (1940) 63 CLR 691, at p 701; Hocking v. Bell (1944) 44 SR (N.S.W.) 468, at p 477 (affirmed in Hocking v. Bell (1945) 71 CLR, at pp 464, 500); Rejfek v. McElroy (1965) 112 CLR, at p 521; Wentworth v. Rogers (No.5) (1986) 6 NSWLR 534, at p 539 or cogent ((3) Rejfek v. McElroy (1965) 112 CLR, at p 521) or strict ((4) Jonesco v. Beard (1930) AC 298, at p 300; Briginshaw v. Briginshaw (1938) 60 CLR, at p 362; Helton v. Allen (1940) 63 CLR, at p 711; Hocking v. Bell (1944) 44 SR (N.S.W.), at p 478 (affirmed in Hocking v. Bell (1945) 71 CLR, at pp 464, 500); Wentworth v. Rogers (No.5) (1986) 6 NSWLR, at p 538) proof is necessary "where so serious a matter as fraud is to be found" ((5) Rejfek v. McElroy (1965) 112 CLR, at p 521). Statements to that effect should not, however, be understood as directed to the standard of proof. Rather, they should be understood as merely reflecting a conventional perception that members of our society do not ordinarily engage in fraudulent or criminal conduct ((6) See, e.g., Motchall v. Massoud (1926) VLR 273, at p 276) and a judicial approach that a court should not lightly make a finding that, on the balance of probabilities, a party to civil litigation has been guilty of such conduct. As Dixon J. commented in Briginshaw v. Briginshaw ((7) (1938) 60 CLR, at p 362; and see, also, Helton v. Allen (1940) 63 CLR, at p 711):
"The seriousness of an allegation made, the inherent unlikelihood of an occurrence of a given description, or the gravity of the consequences flowing from a particular finding are considerations which must affect the answer to the question whether the issue has been proved ...".
There are, however, circumstances in which generalisations about the need for clear and cogent evidence to prove matters of the gravity of fraud or crime are, even when understood as not directed to the standard of proof, likely to be unhelpful and even misleading. In our view, it was so in the present case.
