This article analyzes interventions of judges about digital citizenship in Latin America. The objectives of this work are: (i) to do a review of the literature in relation to political participation in digital scenarios and (ii) to analyze the mechanisms of control that, specifically, judges have begun to impose on the exercise of the digital citizenship. To develop the proposed objectives, it has been selected a judicial decision in a non-separation powers context, which have been analyzed using the methodology of case study. In the examined decision, a citizen used social networks to make political opposition. Different hashtags, photos or messages, sent by social networks, were used as evidences called in a judicial decision for imposing legal sanctions. The article initiates a reflection on this type of controls on the usage of social networking as a mechanism of political opposition. From these forms of control, the state power determines the "correct" ways in which citizens or political parties can perform the digital citizenship.
