本文首先论述了侵权行为归责原则体系并确定其内容,然后主要以无过错责任原则为中心,在界定其定义和其在侵权行为归责原则中与其他原则的区别后,重点指出无过错责任原则并非是绝对的,它仍有免责事由,即如果有免责事由存在就可以不承担责任。这一特点看似类似于过错推定责任,但实际上两者仍有根本差别,不可相混淆。 This article first discusses the system of tort liability attribution principle and its content, and then mainly focuses on the principle of no-fault liability. After defining its definition and its difference from other principles in the principle of attribution of tort, it emphasizes that no-fault liability The principle is not absolute. It still has a disclaimer, that is, it can assume no liability if it exists. This feature may seem similar to the assumption of fault liability, but in fact there are still fundamental differences between the two and should not be confused.
