Privative measures for healthy cyberspace(filtering) may pose a serious challenge to the freedom of information and right to information.Freedom of information as one of citizenship rights is now facilitated through the Internet and cyberspace.This right,based on Article33-Charter of Civil Rights,is one of the fundamental principles of good governance and most important examples of the first generation of human rights law that guarantees citizenship rights.With the rapid expansion of virtual networks in recent years and the occurrence of various types of harm and threats,cyberspace health is one of the concerns to decision-makers in Iran.Therefore,filtering is used as a solution,which led to various criticisms because some people considered filtration as violation of citizenship rights and others referred to the harmfulness of freedom in the uncontrolled cyberspace.However, filtering requires a well-documented legal system;therefore,it is essential to investigate  principles for proper and lawful purging and filtering for the realization of citizenship rights.In this research,the main question is,what are the principles governing(un)justifiable filtering and how does it affect the realization of citizenship rights?Accordingly,the main hypothesis is that given the recognition of the freedom of information,justifiable filtering can affect citizenship rights and its impact is indisputable,but uncontrolled filtering is certainly a violation of citizenship rights
