CHAPTER 12: EQUITABLE ESTOPPEL<br />

12.26 In Waltons St<strong>or</strong>es v Maher, the Mahers owned commercial premises in Nowra which Waltons<br />

was interested in leasing. Waltons wanted to relocate its business in Nowra to new premises and the<br />

Mahers’ site was available. The agreement that was reached was that the Mahers would demolish the<br />

existing premises and erect a new building to meet the specifications of Waltons. A draft agreement<br />

<strong>f<strong>or</strong></strong> lease was sent to the solicit<strong>or</strong>s <strong>f<strong>or</strong></strong> the Mahers. Some amendments were discussed. Waltons’<br />

solicit<strong>or</strong>s indicated that they expected their client’s agreement to the alterations and said they<br />

would let the Mahers know if the amendments were <strong>not</strong> acceptable. The Mahers’ solicit<strong>or</strong>s sent the<br />

amended lease, duly executed by the Mahers, to Waltons’ solicit<strong>or</strong>s ‘by way of exchange’. The letter<br />

was <strong>not</strong> acknowledged by Waltons’ solicit<strong>or</strong>s until two months later. The Mahers began to demolish<br />

the existing premises, as time was critical if they were to complete the demolition and rebuilding in<br />

time <strong>f<strong>or</strong></strong> the start of the lease agreement. Waltons was found to know what the Mahers were doing.<br />

However, after receiving the letter and executed lease, Waltons reconsidered its position and a few<br />

months later wrote to the Mahers’ solicit<strong>or</strong>s saying that the lease had <strong>not</strong> been executed by Waltons<br />

and that Waltons was <strong>not</strong> proceeding with it. The Mahers sued Waltons <strong>f<strong>or</strong></strong> damages <strong>f<strong>or</strong></strong> breach of<br />

contract on the basis that Waltons was estopped from denying the existence of the lease.<br />

12.27 The maj<strong>or</strong>ity of the High Court (Mason CJ, Wilson and Brennan JJ) found <strong>f<strong>or</strong></strong> the Mahers<br />

on the basis of equitable estoppel. (The min<strong>or</strong>ity of Deane and Gaudron JJ found <strong>f<strong>or</strong></strong> the Mahers<br />

on the basis of common law estoppel.) In finding in favour of the Mahers on the basis of equitable<br />

estoppel, the maj<strong>or</strong>ity did so in circumstances where there was no pre-existing contract between<br />

the parties and on the basis that the Mahers <strong>use</strong>d estoppel as the basis <strong>f<strong>or</strong></strong> a ca<strong>use</strong> of action and<br />

<strong>not</strong> merely as a defensive mechanism. In so doing, the High maj<strong>or</strong>ity removed the already <strong>not</strong>ed<br />

(see 12.15) limitations on the operation of promiss<strong>or</strong>y estoppel. In coming to their decision, the<br />

maj<strong>or</strong>ity made it clear that promiss<strong>or</strong>y estoppel was but a species of the broader principle of<br />

equitable estoppel — the other maj<strong>or</strong> species being proprietary estoppel. The underlying rationale<br />

<strong>f<strong>or</strong></strong> equitable estoppel was firmly based in the <strong>not</strong>ion of unconscionability <strong>or</strong> unconscientiousness:<br />

see 2.4–2.5. Mason CJ and Wilson J, at CLR 404; ALR 524, said:<br />

One may there<strong>f<strong>or</strong></strong>e discern in the cases a common thread which links them together, namely, the<br />

principle that equity will come to the relief of a plaintiff who has acted to his detriment on the<br />

basis of a basic assumption in relation to which the other party to the transaction has ‘played such<br />

a part in the adoption of the assumption that it would be unfair <strong>or</strong> unjust if he were left free to<br />

ign<strong>or</strong>e it’: per Dixon J in Grundt v Great Boulder Pty Gold Mines Ltd (1937) 59 CLR 641 at 675<br />

… Equity comes to the relief of such a plaintiff on the footing that it would be unconscionable<br />

conduct on the part of the other party to ign<strong>or</strong>e the assumption.<br />

ELEMENTS OF EQUITABLE ESTOPPEL<br />

12.28 The essence of the principle of equitable estoppel is equity’s concern with circumstances<br />

in which a plaintiff has acted to its detriment on the basis of a fundamental assumption where<br />

the defendant’s role in the adoption of that assumption by the plaintiff is such that it would be<br />

unconscientious to deny the plaintiff equitable relief. It is the defendant’s failure, having induced<br />

<strong>or</strong> acquiesced in the adoption <strong>or</strong> maintenance of the assumption, with knowledge that it would<br />

be relied upon, to fulfil the assumption <strong>or</strong> otherwise permit the plaintiff to avoid the detriment to<br />

which he <strong>or</strong> she has been exposed that makes the conduct of the defendant unconscientious and<br />

which attracts the intervention of equity.<br />
