This is an extract of our Promissory Estoppel document, which we sell as part of our Contract Law Notes collection written by the top tier of University College London students.

The following is a more accessble plain text extract of the PDF sample above, taken from our Contract Law Notes. Due to the challenges of extracting text from PDFs, it will have odd formatting:

Promissory Estoppel
Equitable principle; arguably steps in as relief from the rigours and strictness of the common law.
In a contractual setting, if one party makes a certain type of promise to the other party and they rely on it (usually to their detriment) then the promising party may be estopped from backing out of the agreement. (Strict requirements however), even in the absence of consideration or formality.

'It is the first principle upon which all Courts of Equity proceed, that if parties who have entered into definite and distinct terms involving certain legal results … afterwards by their own act or with their own consent enter upon a course of negotiation which has the effect of leading one of the parties to suppose that the strict rights arising under the contract will not be enforced, or will be kept in suspense, or held in abeyance, the person who otherwise might have enforced those rights will not be allowed to enforce them where it would be inequitable having regard to the dealings
'Estoppel … is a principle of justice and of equity. It comes to this: When a man, by his words or conduct, has led another to believe in a particular state of affairs, he will not be allowed to go back on it when it would be unjust or inequitable for him to do so.' E Cooke The Modern Law of Estoppel (OUP 200)
Hughes v Metropolitan Railway Co.
H, the landlord, gave notice to M, the tenant, requiring M to carry out certain repairs within six months. M asked whether H wished to purchase M's interest in the premises and suggested that repairs be deferred pending negotiations.
The HOL gave M relief against forfeiture for failing to make repairs within the original timeframe because H's conduct had induced M to believe that the time period would stop 'running' during the negotiations. Thus, the six months only ran from the point that negotiations broke down.
To allow H to enforce his original rights would be inequitable, although their Lordships found that H had 'no intention here to take advantage of, to lay a trap for, or to lull into false security those with whom he was dealing'.
Central London Property v High Trees House 1947: READ JUDGEMENT
- C let a block of flats in London to D on a 99-year lease at annual rent of £2500. In 1940, D discovered that the outbreak of war and evacuation of London meant they were unable to let any of the flats so C agreed to reduce the rent to half of this. This promise to accept a reduced rent was unsupported by consideration. At the end of the war, the property marked returned to normal and the flats were fully let. C
demanded that D resume payments from the entire rent but D refused. Lord Denning held that C were entitled to demand the entire rent even though there was no consideration so would be unenforceable under common law principles. Lord Denning cited Hughes as support for his reasoning. Not restrained by Jordan V. Money as not estoppel in the strict sense, distinction b/w Jordan V. Money as that was in common law, this =
in equity. Lecturer: Unconvincing manipulation of the law. Hard to reconcile the two cases.
Jordan V. Money = Statement as to the future does not give rise to estoppel (?)
Doctrine of representation as to existing fact= only works (?) WTAF??
Requirements of promissory estoppel

1. Clear and Unambiguous.
There must be a clear and unequivocal promise which indicates the promisor's intention not to insist on his or her strict legal rights against the promisee -
Woodhouse Israel Cocoa v Nigerian Produce marketing Co Ltd. As Hughes demonstrates, the promise need not be express but may be implied from the circumstances. No estoppel arises if the language is qualified or imprecise - IMT
Shipping v Chansung Shipping Co (The Zenovia).
Silence or inaction will not normally estop a party from suing on the breach. A
party does not lose his or her rights simply because he or she has failed throughout to insist upon strict performance.

TEST: equivalent test of certainty as is required for contractual obligations: Baird Textiles v Marks & Spencer (no long term agreement,
no contract, Mance LJ: this case shows that the "commercial"
presumption of enforceability cannot apply unless the court can first identify an "explicit" or "apparent" promise)

NB: Since promise relates to EXISTING legal rights, the doctrine of promissory estoppel can only be used for the VARIATION of contracts.
Woodhouse Israel Cocoa v Nigerian Produce marketing co LTD. - Held that it was not clear the promise to accept sterling meant to refer to the amount owed or to the currency in which payment should be made. Thus,
they would not be estopped from going back on their promise.
IMT shipping v Chansung Shipping co -

2. Representee relies on representation
Must have influenced behaviour/conduct of the other party. - This highlight promissory estoppel's distinction from common law where a contract is enforceable from whence the contract is formed.
Detrimental reliance ?- Traditionally had to be detrimental reliance as that will usually give rise to a situation where it would be inequitable/unconscionable to go back on your promise. BUT. High Trees = doesn't have to be detrimental but
