4. The case pleaded in the amended statement of claim by the appellants is as follows. The appellants, Messrs. Reid and White, were the directors and shareholders of the appellant Landsal Pty. Ltd., a property developer; Mr. Reid was also a director and shareholder of the appellant W.A. Reid Constructions Pty. Ltd., a building company. In November 1985, Landsal borrowed $1,600,000.00 from REI Building Society (whose liabilities the present respondent has assumed, following the amalgamation of the two societies) to fund construction for it of a residential project by Reid Constructions. Mr. Reid and Mr. White each guaranteed repayment of this sum to REI. In early September 1986, Landsal needed a further $140,000.00 to fund completion of the project. On 9 September REI agreed to advance this further sum. Between 9 September and 19 November, 1986, REI repeatedly assured Landsal that it would make the additional loan moneys available to it, although it is alleged that REI had already decided not to do so. On 18 November, REI told Landsal it would not make the additional loan. It is alleged that REI was in breach of its agreement to advance the further $140,000.00 and that REI's assurances given between 9 September and 18 November, 1986 amounted to conduct in breach of s. 52 of the Trade Practices Act 1974 and to deceit. In paragraph 29 of the amended statement of claim, it is alleged that, in reliance on REI's assurances with respect to the additional $140,000.00, Landsal and Reid Constructions continued work on the project and that Landsal did not seek an alternative source of the additional moneys it needed, but instead, it increased its overdraft with the State Bank of South Australia which went from $20,000.00 to $60,000.00 by 18 November, 1986, an overdraft in respect of which the appellants Mr. Reid and Mr. and Mrs. White had given guarantees to that bank.
