This article discuss the democratization of access to residents of Rio s favelas to judiciary through a temporal and spatial analysis. Data collection included historical datas, socio-economic datas and political datas about the slums reality in Rio and also a quantitative and quali-qualitative research with the civil trials (Jurisprudence) of the Estadual Court of Justice of the state of Rio de Janeiro. The analysis of these data were performed under two approaches: (1) access - individually and collective to the judiciary, (2) the positioning of the magistrates in response to the judicial demands. The results suggest a relationship between: (1) the increase of the access of slum dwellers to the judiciary and improvement of indices of social development, (2) low incidence of collective demands and the omission of the judges in judge such kind of cause, (3) lack of consistency between judicial decisions of magistrates and social reality of the slums and their adjustments over the years, and brings (4) the questioning of some consolidated theoretical beliefs about the key variables in promoting access to justice. From empirical datas, this research suggests possibilities for more effective social transformations when compatible with very local social realities.
