22 Against that background the current application was to amend the statement of claim so as to allege fraud in addition to the currently pleaded unconscionability case. I endeavour to summarise this head of claim by saying that in its essence it is concerned with the proposition that it is unconscionable for the defendant to assert that the 1984 agreement, relevantly cl 4, is unenforceable and illegal, whether that be right or not, in circumstances where the parties entered into the agreement upon the common assumption and belief that it was valid and effectual, and conducted themselves on that basis. Paragraph 22I particularises a great many acts, transactions and events which are said to be of that character occurring during the life of Mr Hancock, who then substantially represented the defendant. Paragraph 22J alleges that after Mr Hancock's death, on 27 March 1992, the defendant denied that the plaintiff was entitled to exercise the option, asserting that it was illegal and unenforceable. It is pleaded that the defendant, on the other hand, asserted that by virtue of a later agreement made in 1989, it was entitled to a 50 per cent interest in the Rhodes Ridge interest and tenements. In the circumstances alleged in par 22K, it is pleaded in par 22L that the defendant's conduct is in breach of its duty as a partner to act truly and justly to the plaintiff and constitutes unconscionable conduct.
