恶意诉讼是一种典型的侵权行为，实践中形态多样，可以类型化为虚假诉讼、权利滥用型恶意诉讼、无据起诉。当前《民事诉讼法》的诚实信用原则和虚假诉讼法院制裁制度、《刑法》的"虚假诉讼罪"都对恶意诉讼进行了规制。但是缺乏民事责任的规制，无法从根本上遏制、惩处恶意诉讼。因此，应在立法上将恶意诉讼列为一种特殊的侵权行为，规定其主观过错为直接故意，其损害包括被侵权人的预期利益损失。同时，为了更好地发挥侵权责任法的遏制和阻碍违法行为功能，基于恶意诉讼侵权人的主观恶意，对恶意诉讼侵权行为人的损害赔偿责任可以适用惩罚性赔偿责任。

Malicious litigation is a kind of typical tort, which can be classified as false litigation, malicious litigation based on the abuse of rights and unwarranted prosecution. At present, the principle of good faith in civil procedure law, the sanction system of false lawsuit court and the crime of false lawsuit in criminal law all regulate malicious lawsuit. However, without the regulation of civil liability, it is impossible to fundamentally curb and punish malicious litigation. Our country should in the legislation think malicious litigation as a kind of special infringement behavior. The malicious litigation tort's fault is direct intentional and its damage including expected benefits losses. The damage to the malicious lawsuit tort should include the expected benefits. The punitive damages should be applied to the malicious litigation tort.
