The first of the additional questions formulated for decision at the trial of questions 1 - 6 raises the issue of whether the statement of claim so far as it contains allegations of unconscionable conduct and a breach of s51AA of the TP Act discloses a reasonable cause of action.
The factual allegation pleaded in support of the claim of unconscionable conduct may be summarised as follows:-
(a) the first respondent knew that the executive government of the Territory, its officers and the Police had no experience in conducting events like the Rally;
(b) the first respondent knew that the public, the executive government of the territory, its officers, the Police and Rally officials trusted and relied upon the first respondent to advise them in order to ensure that the Rally was safely conducted in accordance with the law and without exposing the public or the Rally officials to an unreasonable risk of injury;
(c) in breach of a duty owed by the first respondent to the public, the executive government of the Territory, its officers, the Police and Rally officials, and acting in its own interests, the first respondent determined to conduct the Rally in a manner that was unsafe with respect to the public and Rally officials and thereby acted unconscionably within the meaning of s51AA of the TP Act;
(d) The second respondents knew that the executive government of the Territory, its officers, the Police, members of the Darwin Motor Sports Club Inc. and Rally officials relied upon the permit issued by the second respondents to the first respondent, and upon representations made by the second respondents to them that it would act in their best interests, and that it was qualified to control the Rally and had satisfied itself, and had put in place necessary controls to ensure, that the Rally would be conducted safely;
(e) in breach of a duty to act in the interests of the public, the executive government of the Territory, its officers, the Police, the members of the Darwin Motor Sports Club Inc. and the Rally officials, the second respondents issued a permit for the Rally when it should have known that the Rally would not be conducted safely;
(f) had the respondents respectively not acted unconscionably, the Rally would not have been permitted to occur, or alternatively would only have been permitted to occur on terms that it be conducted safely, or in the further alternative the deceased would not have acted as a Rally official.
(g) the deceased's death was caused by the respective breaches by the first and second respondents of s51AA of the TP Act and by reason of such breaches the applicant, the estate and the children have suffered loss and damage.
As the learned primary judge pointed out, s51AA of the TP Act extends the remedies available under the TP Act to unconscionable conduct to the extent that such concept is already part of the general law. The section does not expand equitable concepts of unconscionable conduct.
Senior counsel for the applicants based his argument on s51AA of the TP Act principally upon the allegations in the statement of claim designed to support findings that the first and second respondents respectively owed fiduciary duties to the deceased. He contended that, to the extent that the learned trial judge acted on the basis that s51AA was limited in its operation to "unconscionable dealing", in the sense that that expression was used by Deane J and Dawson J in Commercial Bank of Australia Ltd v Amadio (1983) 151 CLR 447, he was in error. It was contended on behalf of the applicant that the words "conduct that is unconscionable" appearing in s51AA of the TP Act comprehend all of the categories of conduct which have traditionally been regarded as fraudulent in equity. He drew attention to the six categories of equitable fraud identified by the learned authors of Equity: Doctrines and Remedies, Meagher, Gummow and Lehane, 3rd ed at par 1210.
I note that in Commercial Bank of Australia Ltd v Amadio at 461, Mason J considered the usual meaning of the expression "unconscionable conduct" in the following passage:
"Historically, courts have exercised jurisdiction to set aside contracts and other dealings on a variety of equitable grounds. They include fraud, misrepresentation, breach of fiduciary duty, undue influence and unconscionable conduct. In one sense they all constitute species of unconscionable conduct on the part of a party who stands to receive a benefit under a transaction which, in the eye of equity, cannot be enforced because to do so would be inconsistent with equity and good conscience. But relief on the ground of 'unconscionable conduct' is usually taken to refer to the class of case in which a party makes unconscientious use of his superior position or bargaining power to the detriment of a party who suffers from some special disability or is placed in some special situation of disadvantage, e.g., a catching bargain with an expectant heir or an unfair contract made by taking advantage of a person who is seriously affected by intoxicating liquor. Although unconscionable conduct in this narrow sense bears some resemblance to the doctrine of undue influence, there is a difference between the two."
In the same case, Deane J, with whom Wilson J agreed, at 474, stated as follows:-
"The equitable principles relating to relief against unconscionable dealing and the principles relating to undue influence are closely related. The two doctrines are, however, distinct. Undue influence, like common law duress, looks to the quality of the consent or assent of the weaker party. ... Unconscionable dealing looks to the conduct of the stronger party in attempting to enforce, or retain the benefit of, a dealing with a person under a special disability in circumstances where it is not consistent with equity or good conscience that he should do so. The adverse circumstances which may constitute a special disability for the purposes of the principles relating to relief against unconscionable dealing may take a wide variety of forms and are not susceptible of being comprehensively catalogues [sic]."
It seems to me likely that the expression "conduct that is unconscionable" appearing in s51AA of the TP Act is intended to have the same meaning as the more frequently used expressions "unconscionable conduct" and "unconscionable dealings". It may therefore be debatable whether s51AA has a sphere of operation quite as wide as that for which Mr Maurice QC, senior counsel for the applicants, contended. It cannot, however, in my view, be said that the argument in favour of a wide construction of s51AA is untenable or doomed to failure (Murex Diagnostics Australia Pty Ltd v Chiron Corporation (1995) 128 ALR 525; General Steel Industries Ltd v Commissioner for Railways (1964) 112 CLR 125; Walton v Gardiner (1993) 177 CLR 378).
Although Mr Maurice disclaimed any reliance on "the unconscionable bargain type of situation", he did assert an abuse by the respondents respectively of the relationships between them and the deceased. He emphasised the vulnerability of the deceased, who was recruited as a volunteer to act in the interests of the respondents, to exploitation by the respondents if they did not fulfil their undertakings to him and others. The statement of claim pleads that each of the respondents knew that persons in the class to which the deceased belonged trusted and relied upon them as to important matters, and that they acted in disregard of such trust and reliance.
It has been said on a number of occasions that it is impossible to describe all of the situations in which relief will be granted on the ground of unconscionable conduct (see Blomley v Ryan (1956) 99 CLR 362 per Fullagar J at 405; Commercial Bank of Australia Ltd v Amadio per Mason J at 461-462 and Deane J at 474). Moreover, the categories of fiduciary relationships are not closed (Hospital Products Limited v United States Surgical Corporation & Ors (1984) 156 CLR 41 esp. per Gibbs CJ at 68, Mason J at 96 and Dawson J at 141-142). In Breen v Williams (1994) 35 NSWLR 522 at 543-544, Kirby P stated certain propositions and cited authority in support of them. Such propositions include the following:-
"1. The fiduciary principle is in a state of development whose impetus has not been spent to the present day ...;
2. As society becomes more complex, it is both necessary and appropriate for courts of equity to recognise new fiduciary allegations and to protect incidents of new or changing relationships ...;
3. What began with the trustee-beneficiary relationship ... has extended, by analogical reasoning, to other relationships including trust and confidence ...;
