This article analyses the application of Law 20.500 on Associations and Citizen Participation in Public Management in three municipalities in the Metropolitan Region, emblematic for Chilean political classes. The selected cases were Santiago, Providencia and Las Condes. The results show that it is the law itself that has put barriers to local citizen participation and the shortcomings of the rules do not allow proper development of citizen participation at the local level. The methodology considers qualitative and interpretative analysis. Including activities such as interviews with key persons, data collection and analysis.
