古罗马法中有了诚实信用原则的雏形,近现代欧洲各国的法典的编纂运动中诚实信用原则被真正吸收为法律准则。在现代各国的民法、合同法等法律法规中都将诚实信用原则作为一条最重要的法律原则予以重视,这一原则已成为合同法的“帝王规则”,在现代经济合同的制定、履行与合同纠纷的处理中,具有最优先的约束力。 With the embryonic form of the principle of good faith in ancient Roman law, the principle of good faith in the codification of the codes of law in modern European countries was really absorbed into the legal norms. In the modern civil law, contract law and other laws and regulations are the principle of good faith as one of the most important legal principles to be valued, this principle has become the contract law “rule of the emperor,” in the modern economic contract development, implementation and contract Dispute processing, with the highest priority of binding.
