允诺禁反言原则及对我国合同法的影响

Promissory Estoppel Principle and Its Effect on China's Contract Law

允诺禁反言原则产生于十九世纪后期,是英美法系合同法中的现代理论,是合同法与衡平法相融合的产物,旨在强制执行某些没有对价支持的合同。英国的允诺禁反言原则于二十世纪中期获得了新生,美国《合同法重述》及信赖理论在二十世纪三十年代的兴起为该原则在美国的确立和发展奠定了基础,使其作为对价的补充原则而获得了广泛接受。

Initiated in late 19th century, promissory estoppel is a modern doctrine of Anglo-American contract law. It is a fusion of the contract law and equity, aiming at enforcing some contractual obligations without consideratin. Promissory estoppel revived in the middle of the 20th century in Britain, while in the United States, it has flourished from 1930s, taking the advantage of the introduction of the Restatement of the Law of Contracts and the emergence of the reliance theory, it could thus apply as a supplement to consideration.
