The authority for that proposition is given as (a) Gasiunas v Meinhold (1964) 6 FLR 182, 190 per P E Joske J; (b) Elibank-Murray v Dunne (1982) NSW Conv R 55-048 at 56, 289 per Powell J; (c) Trowmet Pty Ltd v Lew (1992) V Conv R 54-427 at 65,046 per Phillips J; (d) McConville v Australian Telecommunications Commission (1991) NSW Conv R 55-602 at pp 59,411-2 per McLelland J; (e) Drulroad Pty Ltd v Gibson (1992) NSW Conv R 55-637 at 59,643 per Hodgson J which the learned author says are "examples of cases where the court has accepted that acts of part performance or the existence of an estoppel can overcome the absence of a memorandum in writing and support a caveat."
47 At the oral hearing, Mr Davie merely referred me to this passage and left it at that. With respect, that was quite unhelpful. In a case where there is a crucial point involved, as this point clearly is, the Court expects counsel to proceed beyond the textbook and cite and explain the leading cases, the primary source of the proposition of law which must be established. I mention this because I have found more and more that counsel, presumably at high fee, fob the judge off with a set of textbook references and then make the judge do the research work. Counsel are involved to assist the judge to find the truth of fact and law and must not take this second rate short cut.
48 In his written submissions, Mr Davie went a little, but not much, further. He cited (f) ANZ Banking Group Ltd v Widin (1990) 26 FCR 21, 33; 102 ALR 289, 301 and then submitted, "By extension, it is submitted that there is no reason why a party should not be estopped from relying on the section." He then repeated the passage from Lindsay preceding it with the comment "It appears to have been accepted in NSW (and elsewhere) that …".
49 Mr Blake merely submitted that the doctrine of part performance is irrelevant except in a suit for specific performance. He said that specific performance was nowhere sought in the present proceedings.
50 It is necessary to consider the authorities that I have tagged (a) to (f) in my summary of Mr Davie's submissions.
51 Case (a) is no authority as it has been held on more than one occasion to be inconsistent with the mainstream of authority and not to be followed. In any event, it is a straight specific performance type case.
52 Case (b) involved the grant of a profit a prendre. Part performance failed as a defence on the facts. However the discussion is useful as showing that part performance is relevant in such a case. It is probably more helpful to go to the authority on which Powell J based his discussion, the decision of the House of Lords in Mason v Clarke [1955] AC 778, which was also followed in Australia in Unimin Pty Ltd v Commonwealth (1977) 45 LGRA 338.
53 Case (c) was a simple case leading to a suit for specific performance.
54 Case (d) is of no assistance in the present case.
55 Case (e) is a mortgage case. Part performance failed on the facts, but Hodgson J recognised its applicability.
56 Case (f) involved the situation where a bankrupt orally agreed to give the bank a mortgage. The bank advanced the money, but no mortgage was ever signed. The trustee sought a declaration that a registered mortgage was void against the trustee as having been granted within the proscribed six month period. This was successful at first instance (see (1990) 94 CLR 613). The question before the Full Federal Court was the date the mortgage became effective. Although Hill J spent the bulk of his reasoning on the question of what is unequivocal conduct necessary to constitute part performance, it is clear from FCR 34 and 37 (ALR pp 302 and 306) that he considered that part performance applied in that case even though it was not a case for specific performance. He said at 37-8 (306), "It would be unconscionable to permit the bankrupt or the trustee claiming through him to rely upon the legal invalidity of the contract on the faith of which the bankrupt induced the bank to become liable on (his) bills." Wilcox and Foster JJ agreed.
57 The Australian edition of Fisher & Lightwood on Mortgages (Butterworths, Sydney, 1995) para [1.23] accepts that part performance may provide an escape around s 23C relying on Widin's case.
58 Widin's case was followed by Burchett J in Carr v McDonald's Australia Ltd (1994) 63 FCR 358 in that his Honour applied part performance to a case of the grant of a franchise. However, the claim failed on the facts.
59 Another authority in point which was not cited to me is Hammon v O'Brien (1990) 5 BPR 11,163, 11,166, where, in a case involving the interest of a de facto spouse in the proceeds of sale of a property, M H McLelland J recognized that the 23C barrier could be surmounted if "she can establish that circumstances exist which render reliance by the plaintiff on s 23C, or the assertion by the plaintiff of a legal interest free of any equitable interest of the defendant, unconscionable."
60 On the basis that the authorities support the application of the doctrine, was there part performance in the instant case? It is more likely than not that the solicitors would not have done the work on the case after 5 October 2001 if they had not had Baker's agreement to provide a caveat. Furthermore, the evidence allows only of the conclusion (from any version of the vital conversation) that Mr Baker knew that that was the case. Accordingly, apart from the matters which I will consider under other reasons and which bear on the vital question as to whether it would be unconscionable in all the circumstances for Mr Baker to plead s 23C, there is sufficient part performance to surmount the barrier otherwise cast by s 23C.
61 Because of what I have just said, it is unnecessary to deal separately with estoppel. The same basic equity is involved. However, the court has been reluctant to allow free use of principles of estoppel to outflank the fundamental requirements of property law.
