公序良俗原则是公共秩序和善良风俗的简称。公序良俗原则具体化的方法有类型化方法和价值补充方法。其中,类型化方法维系着法定主义与确定性的一端,价值补充方法维系着自由裁量与灵活性的一端,两者共同实践着公序良俗原则的价值。总之,公序良俗作为民法的基本原则之一,应当被逐步地应用于司法实践。 The principle of ordre public good is short for public order and good customs. The methods of substantiating the principle of public order and good morals are typified and supplemented by values. Among them, the typological method maintains one end of legalism and certainty. The method of value supplementation maintains one end of discretion and flexibility, and both of them together practice the value of the principle of public order and good customs. In short, public order and morality as one of the basic principles of civil law should be gradually applied to judicial practice.
