Discussion on Legal System Adaptability of Implied Anticipatory Breach of Contract and Precarious Right to Defense; 不安抗辩权制度及预期违约制度分别是大陆法系和英美法系现代合同法的重要制度。
Two similar theories, implied anticipatory breach of contract and precarious right to defense, are simultaneously adopted by Chinese contract law. 我国合同法规定了默示预期违约与不安抗辩权这两种有较多相似之处的制度。
Implied anticipatory breach of contract is a special form of breach of contract which only exists in common law system, meanwhile the countries with traditions of continental law have adopted precarious right to defense instead of implied anticipatory breach of contract. 默示预期违约是英美法系的特有制度,大陆法系各国民法典一般只规定不安抗辩权,它是作为双务合同的特殊效力规定于合同的效力部分。
