This paper delves into the issue of the expansion of the subjective scope of res judicata in shareholder representative litigation in China. By integrating the amendments to China’s “Company Law” and relevant judicial interpretations, it analyzes the current status, existing problems, and underlying causes of the expansion of res judicata in shareholder representative litigation, with a particular focus on its impact on the protection of company and other shareholders’ rights and interests. Through an examination of the legitimacy of the litigation exercise rights of plaintiff shareholders in shareholder representative litigation, the paper clarifies their legal relationship with the company as litigation trustees. From the perspective of safeguarding the interests of other shareholders, the paper proposes pathways to reasonably limit the expansion of the subjective scope of res judicata in shareholder representative litigation and other supporting measures to improve the shareholder representative litigation system, including refining the litigation notification procedures, introducing a system of reasons for not initiating a lawsuit, and reducing litigation costs.
