Promissory Estoppel
Promissory Estoppel
Doctrine of Promissory Estoppel evolved to overcome the injustices
of consideration - ‘estopped’ means ‘precluded’ or ‘prevented’ - the
very essence of Promissory Estoppel is that the promisor is precluded
from going back to his or her promise even though the promise is not
supported by consideration moving from the promise.
Equity also
developed other areas of estoppel including propriety estoppel, where,
if X, the owner of property, induced Y to believe that Y had an
interest in that property, equity would recognise and enforce Y’s
interest in that property.
Waltons Stores (interstate) Ltd v
Maher (1988) - recognized that the various forms of estoppel in equity
all arose in situations where it would be unconscionable for a
plaintiff’s against a defendant to be denied.
· The modern
doctrine of equitable estoppel can provide relief in various other
areas where contractual remedies are unavailable, including:
1.
Where, during negotiations to enter into a contract, an offeree,
believing that the offer will not be revoked proceeds to act to his
detriment upon that belief;
2. Where there has been non-compliance with the statutory requirement of writing with respect to a contract involving land;
3.
Where the rule in Hoyt’s Pty Ltd v Spencer (1919) precludes the finding
of a collateral contract: Wright v Hamilton Island Enterprises [2003];
4.
Where the doctrine of privity prevents a third party to the contract
from enforcing it: Trident General Insurance Co Ltd v McNiece Bros
(1988);
5. Where a contract is rendered illegal and thus
unenforceable because a party to it is not licenced as required by
legislation, but had stated to the other party that he or she was so
licenced.
Development of Equitable Estoppel
An
illustrative early case of promissory estoppel is Central London
Property Trust v High Trees House Ltd [1947] - where it was found that
even though the promise to accept a reduced rent was not supported by
consideration, principle of promissory estoppel would have been raised,
preventing recovery of forgone rent.
· For many years the operation of promissory estoppel principles were subject to two important limitations:
1.
the promise had to be in the context of a pre-existing legal
relationship. In High Trees, this was satisfied in that the parties
were in a lease relationship and the promise was in relation to the
terms agreed under that lease.
2. promissory estoppel could only
be used as a defence to an action bought by the promisor to the
promisee. It was said that it could only be used as a ‘shield’ and not
as a ‘sword’. In High Trees, this was satisfied as it was HTH, the
defendant/promise, that would have used promissory estoppel as a
defence to a claim for the forgone rent by CTP, the plaintiff/promisor.
***In
Australia, the doctrine of promissory estoppel was first
authoritatively accepted by the High Court in Legione v Hateley (1983).
{IMPORTANT}
*
The most significant High Court decision on the subject was 5 years
later in Waltons Stores (interstate) Ltd v Maher (1988) - the
significance of this case was that it was a key case which has led to
the removal of both of the above limitations on the operation of the
doctrine of promissory estoppel - on finding in favour of the Mahers on
the basis of promissory estoppel, the majority did so in circumstances
where there was no pre-existing contract between the parties and on the
basis that the Mahers used estoppel as the basis for a cause of action
and not merely as a defensive mechanism - the underlying rationale for
equitable estoppel was firmly based on the notion of uncnscionabiliy.
Elements of Promissory Estoppel
To
establish a case based upon principles of equitable estoppel there
needs to be a promise or a sufficiently clear and unambiguous
representation: Australian Crime Commission v Gray [2003].
6 elements noted by Brennan J in Waltons include:
1 - Assumption or Expectation:
If assumption is one of an existing fact, a case of common law estoppel arises.
If
the assumption is that the promisor will act in a particular way in the
future, equitable estoppel will arise - as in the case of Waltons, the
promisee needs to show that he or she assumed that a particular legal
relationship existed or would exist between the parties to the dispute.
However,
Brennan J’s requirement of a legal relationship would exclude equitable
estoppel from a promise made where the promise assumes that the
promisor will behave in a manner outside the context of a legal
relationship, e.g. A promises to pay B $200 within 10 days - A’s
behaviour is outside ant existing or expected legal relationship
between A and B.
Mobil Oil Australia Ltd v Lyndell Nominees Pty
Ltd (1988), where full court of the Federal Court found that ‘it is a
necessary element of the principle that the defendant has created or
encouraged an assumption that “a particular legal relationship” of
“interest” would arise or be granted’.
A broader view was taken
in Austotel Pty Ltd v Franklins Selfserve Pty Ltd (1989) where
Priestley JA indicated that it was enough that the assumption was in
relation to ‘a promise [would] be performed’. Some cases have held that
the plaintiff’s equitable estoppel claim failed because it was not
reasonable for the plaintiff to have adopted the assumption: Salienta
Pty Ltd v Clancy [1990].
2 - Inducement: The assumption adopted
by the promisee must have been induced by the conduct of the promisor -
in most cases the conduct will be an express representation or promise.
In Legione v Hateley, it was said that the promise must be clear and unequivocal.
However,
Waltons makes clear, in some cases it can be implied; it stresses that
it is the assumption that is induced rather than a promise or
representation that establishes equitable estoppel. - In Waltons the
inaction by Waltons, in the circumstances, induced the Mahers to act on
the basis of the assumption they had made.
3 - Reliance: The
promise must act or refrain from acting in reliance on the assumption.
It is not clear whether the promisee’s action taken on the basis of the
assumption has also to be reasonable in the circumstances.
4 -
Knowledge or Intention: The promisor must know or intend that the
promise will act or refrain from acting in reliance on the assumption
or expectation; it can be actual or constructive knowledge.
In cases of assumptions based upon a promise or representation, knowledge is ‘easily inferred’: Waltons
In
cases where the assumption arises outside the context of a promise or
representation the requirement of knowledge or intention is more
difficult to establish: Waltons, however as shown in this case, it can
be established.
5 - Detriment: The plaintiff must suffer, or
stand to suffer, detriment if the assumption made by the plaintiff is
not fulfilled, there must be a link between the detriment and the
assumption or expectation.
In Thompson v Palmer (1933), Dixon J
said that the plaintiff must suffer detriment in the sense that ‘as a
result of adopting [the assumption or expectation] as the basis of
action or inaction, [the plaintiff] will have placed himself in a
position of material disadvantage if departure from the assumption is
permitted’.
The notion of detriment conjures up the idea that
the plaintiff will be worse off in some way, it is not enough that the
plaintiff acted upon the defendant’s promise.
In Je Maintiendrai
Pty Ltd v Quaglia (1980), it held that it was necessary that the
promise would ‘result in some detriment and therefore some injustice’
to the plaintiff.
The detriment suffered can’t be minor: Hawker
Pacific Pty Ltd v Helicopter Charter Pty Ltd (1991) - it has been
variously described as needing to be material or significant or
substantial.
In assessing the existence of detriment one must
distinguish between expectation and reliance loss. In context of the
facts of Waltons, the expectation loss suffered by the Mahers was the
loss of rent they expected Waltons to pay during the term of the
anticipated lease. The reliance loss was the wasted expenditure
incurred in demolishing and rebuilding the premises - it was the
reliance loss and not the expectation loss that established detriment
in that case.
The significance of establishing detriment is that
it is this factor which makes it unconscionable or unjust for the
promisor to depart from the assumption.
6 - Failure to avoid
detriment: The defendant must have failed to act to avoid the plaintiff
suffering detriment. One way in which action could be taken to avoid
the detriment is by simply fulfilling the assumption or expectation.
However,
the object of equitable estoppel is not to compel the plaintiff to
fulfil the assumption or expectation, but rather to avid detriment if
the assumption or expectation goes unfulfilled, this might be done by
advising the plaintiff, before irreversible detriment is incurred, that
the assumption is mistaken.
Similarly the plaintiff may be able
to withdraw from the promise and the assumption that it has generated
before any irreversible detriment is incurred.
Relief based upon Equitable Estoppel
·
Estoppel is not an exception to the requirement of consideration -
deeds represent a true exception to estoppel because the promise who
has not provided consideration is entitled to sue for the contractual
remedy of damages.
· A promisee who has not provided
consideration, but is able to establish the elements of promissory
estoppel, is not entitled to the contractual remedy of damages -
establishing the elements of estoppel means the plaintiff is entitled
to some equitable relief, court will enforce this equity but does not
enforce the promise.
· Equity is enforced by the court making
whatever order it deems to be appropriate to the circumstances - relief
available at the discretion of the court. It may be that the only way
to enforce the equity is to order the equivalent of what would have
been damages assessed on the basis of a breach of contract.
· In
exercising this discretion, the courts have generally made it clear
that the orders to be granted are based upon avoiding the plaintiff
from suffering detriment: Mobil Oil v Lyndell Nominees.
· There
have been cases that suggest, in the appropriate case the remedy should
be framed on the basis of making good the assumption or expectation
relied upon by the plaintiff: Giumelli v Giumelli (1999) - High Court
held, there was nothing in earlier cases that precluded a court from
granting relief in equitable estoppel cases, on the basis of making
good the plaintiff’s assumption or expecatation.
In the case,
the court granted the son monetary relief to the value of the property
that should have been transferred to him by the parents - High Court
did not order a transfer of property to the son, the monetary
compensation was a remedy based upon the expectation rather than any
reliance loss or actual detriment suffered by the son.
* It
appears that the court will initially seek to award a remedy on the
detriment suffered basis where that can be readily determined and
established - if it cannot, then a remedy based upon making good the
plaintiff’s assumption or expectation is more likely.
