With the continuous development of the legal construction of our country, the civil procedure system plays an increasingly important role in guaranteeing the legal rights and interests of citizens. However, the abuse of the right of action, repeated prosecution and other problems are repeated, which not only wastes the limited judicial resources, but also has a serious impact on judicial justice and efficiency. The causes of the abuse of litigation right are various, and the main cause is that the low litigation cost leads to the low illegal cost, and the current civil procedure law in China does not directly regulate the abuse of litigation right. This paper aims to summarize the current case identification of the abuse of litigation right at home and abroad, and improve the provisions on the abuse of litigation right in the civil Procedure Law through case analysis and learning from foreign experience. Make clear the constituent elements, identification criteria, legal liability and so on of abuse of suit right.
