8 As stated in Equity Doctrines and Remedies, Meagher Gummow Lehanne, fourth edition p 550, the current state of authority in Australia as to equitable or promissory estoppel is encapsulated in the following passage from the judgment of Brennan J in Waltons Stores (Interstate) Limited v Maher at 428-9; 542. But in reading that passage it should be understood that, particularly in cases involving an assumption about a state of affairs, reasonable notice of an intended departure from the assumption may avoid any sufficient detriment: Commonwealth v Verwayen (1990) 170 CLR 394 at 442; 95 ALR 321 at 354; BC9002031 per Deane J. The passage from the judgment of Brennan J in Walton's case states:
"It is necessary for the plaintiff to prove that (1) the plaintiff assumed that a particular legal relationship then existed between the plaintiff and the defendant or expected that a particular legal relationship would exist between them and, in the latter case, that the defendant would not be free to withdraw from the expected legal relationship; (2) the defendant has induced the plaintiff to adopt that assumption or expectation; (3) the plaintiff acts or abstains from acting in reliance on the assumption or expectation; (4) the defendant knew or intended him to do so; (5) the plaintiff's action or inaction will occasion detriment if the assumption or expectation is not fulfilled; and (6) the defendant has failed to act to avoid that detriment whether by fulfilling the assumption or expectation or otherwise. For the purposes of the second defendant, a defendant who has not actively induce the plaintiff to adopt an assumption or expectation will nevertheless be held to have done so if the assumption or expectation can be fulfilled only by a transfer of the defendant's property, a diminution of his rights or an increase in his obligations and he, knowing that the plaintiff's reliance on the assumption or expectation may cause detriment to the plaintiff if it is not fulfilled, fails to deny to the plaintiff the correctness of the assumption or expectation on which the plaintiff is conducting his affairs."
9 Although I could assume that there was an expectation that repayment by installments was agreed, as a result of the defendant's actions, the plaintiff has led no evidence of acting or abstaining from acting in reliance on the expectation and that the defendant knew or intended him to do so. All that has happened is the lease arrangements have continued. There are no other actions referred to by the plaintiff. In these circumstances, I see no room for the operation of any estoppel. I turn to the question of an offsetting claim.
10 Mr Chandler annexed to his affidavit a copy of an ordinary statement of claim issued in the District Court by the plaintiff against the defendant claiming damages for breach of the lease. The statement of claim does not identify the breach of the lease and claims damages, the principal one being for reprinting casting cards for performance of some $233,540. Nowhere in his affidavit evidence does Mr Chandler depose to any facts to prove the offsetting claim. As far as breach is concerned the change of position by the defendant on repayment by installments does not constitute a breach.
11 The court's task in assessing an offsetting claim has been dealt with in a number of cases. For instance, in Edge Technology Pty Ltd v Lite-On Technology Corp (2000) 18 ACLC 576, Santow J had the following to say at paras 24 and 25:
"It is here again true (as it was in Goldspar Australia Pty Ltd v KWA Design Group Pty Ltd (1999) 17 ACLC 456) that it "is not my task in the present proceedings to seek to resolve the competing claims of the Plaintiff and the Defendant": per Austin J at 462. Rather, it is to "resolve whether, for the purposes of s 459(H)(1)(a), there is a genuine dispute between the Plaintiff and the Defendant about the existence or amount of the debt to which the Defendant's statutory demand relates": Austin J at 462. Or alternatively, whether there is a genuine counter-claim, set-off or cross-demand against the Defendant and if so, in what amount. In particular, how should it be quantified; at a nominal $1 or at a large figure and if the latter, how is the quantification to be arrived at? The latter question essentially asks whether the counter-claim or set-off is fictitious or merely colourable; Jesseron Holdings Pty Ltd v Middle East Trading Consultants Pty Limited (No 2) (1994) 12 ACLC 490; 13 ACSR 787. In that context, to come up with a plausible contention to (sic) requiring further investigation which, if later established, would preclude there being an offsetting claim. That would not establish that the counter-claim or set-off was fictitious, or merely colourable. In that sense, the counter-claim or set-off is not the reciprocal of the statutory demand debt. Rather it is a means of offsetting the statutory demand debt with a genuine counter-claim or set-off.
