The resolution of the membership assembly of the rural collective economic organizations serves as a vital instrument for rural collective economic organizations governance, bearing significant implications for member rights and the efficacy of organizational governance. The determination of its validity constitutes a critical issue necessitating resolution during the implementation of the Rural Collective Economic Organization Law. As an act of will formation by the rural collective economic organizations, the validity of such a resolution is grounded in its origin as an act performed by an internal organ of the organization based on group autonomy. The determination of a resolution’s validity encompasses the entire process of assessing its legal status, including whether it is duly constituted, valid, voidable, or void. Currently, the determination of validity for membership assembly resolutions faces several theoretical ambiguities and practical challenges: First, due to unclear boundaries for judicial intervention, judicial practice often excludes validity determinations from the scope of judicial review. Second, the absence of direct statutory criteria for establishing the constitution of a resolution leads to a failure to clearly distinguish between its formation/effectiveness and its validity determination. Third, undefined rules for voiding resolutions result in inconsistent application of voidability. Fourth, the lack of clear rules for determining invalidity creates confusion regarding the legal basis for such determinations and their application. Addressing these challenges requires exploring logical pathways to refine the rules governing the validity determination of rural collective economic organizations membership assembly resolutions, providing theoretical guidance for judicial practice. First, the boundaries of judicial intervention must be clarified, specifically addressing whether, when, and to what extent courts may intervene in validity determinations to ensure the legality and appropriateness of such intervention. Second, a clear distinction must be drawn between a resolution’s formation/effectiveness and its validity determination, refining constitutive requirements concerning subject matter and procedure to accurately identify its legal status. Third, the rules for voiding resolutions should be enhanced, establishing infringement of members’ lawful rights and interests as the legitimate ground for voidance, recognizing rural collective economic organization members as eligible subjects holding the right to request voidance, defining the scope of infringed rights based on the Rural Collective Economic Organization Law, and carefully weighing autonomy against legality when voiding resolutions to provide clear guidance for member remedies. Finally, rules for determining the invalidity of resolutions must be established, clarifying the applicable legal basis. A systematic framework for determining resolution validity will enhance the governance efficacy of rural collective economic organizations.
