23 Judge Bowen Pain referred to the High Court decision of Bunbury Foods Pty Limited v NAB & Anor (1983-84) 153 CLR 491 at 502 and held that "In the present case, although the notice requested payment by 13 July 2000, it was not enforced in any way until September. The defendants, at that time, taking steps to meet some but not all of the liability. Applying the High Court's words, I do not think that the notice was unreasonable." The reasonableness of the notice to the defendants in relation to the guarantee, giving them one day (even less than the time period given to the company) to repay the whole of the amount due under both facilities was not ventilated.
24 In Henderson v Henderson [1843-60] All ER 378, Wigram VC said at 382:
"I believe I state the rule of the Court correctly when I say that, where a given matter becomes the subject of litigation in, and of adjudication that litigation to bring forward their whole case and will not (except under special circumstances) permit the same parties to open the same subject of litigation in respect of matter which might have been brought forward as part of the subject in contest, but which was not brought forward, only because they have, from negligence, inadvertence, or even accident, omitted part of their case. The pleas of res judicata applies, except in special cases, not only to points upon which the Court was actually required by the parties to form an opinion and pronounce a judgment, but to every point which properly belonged to the subject of litigation, and which the parties, exercising reasonable diligence, might have brought forward at the time."
25 In Port Melbourne Authority v Anshun Pty Limited (1981) 147 CLR 589, Gibbs CJ, Mason and Aickin JJ said:
"The distinction between res judicata (in England called 'cause of action estoppel') and issue estoppel was expressed by Dixon J in Blair v Curran (20) in these terms: "in the first the very right or cause of action claimed or put in suit has in the former proceedings passed into judgment, so that it is merged and has no longer an independent existence, while in the second, for the purpose of some other claim or cause of action, a state of fact or law is alleged or denied the existence of which is a matter necessarily decided by the prior judgment, decree or order.'
