Facts
- The case involved a husband and wife undergoing divorce proceedings.
- The husband promised to pay the wife £100 annually as a tax-free maintenance payment.
- The promise was not supported by any formal consideration from the wife; she did not offer anything in return.
- The husband did not request the wife to forbear from applying to the court for maintenance.
- The wife, aware of the husband's financial situation, did not initially claim the promised payment.
- Several years later, the wife brought legal action to claim arrears under the agreement.
- The central issue was whether the husband was legally bound by his promise and if the wife could enforce the payment based on promissory estoppel.
Issues
- Whether promissory estoppel can create a new cause of action in the absence of consideration.
- Whether the wife's forbearance from applying to court for maintenance constituted valid consideration.
- Whether promissory estoppel could be invoked to enforce the husband's promise as a contractual obligation.
Decision
- The court held that promissory estoppel cannot create a cause of action where no consideration exists.
- The wife's forbearance did not amount to valid consideration because the husband did not expressly request it.
- The husband's promise was unenforceable as a contractual claim due to the absence of consideration.
- The doctrine of promissory estoppel could not be used by the wife as the basis for her claim; it is only available as a defence (a "shield," not a "sword").
Legal Principles
- Promissory estoppel operates to prevent a party from asserting their strict legal rights only where it would be inequitable to do so, provided the other party has relied on the promise.
- The doctrine cannot replace the requirement for consideration in contract formation.
- Promissory estoppel serves only as a defence to stop a party from enforcing full legal rights, not as a means to create new rights or causes of action.
- The necessity of consideration is a fundamental element of contract law and is not displaced by equitable principles.
Conclusion
Combe v Combe confirmed that promissory estoppel may only be used as a defence and cannot create a new cause of action in the absence of consideration, thereby reinforcing the essential requirement of consideration in contract formation and the limited function of the doctrine within English law.
