Abstract: The triumph of democratic constitutionalism and the legal effectiveness of the Constitution brings a new role of the interpreter. The judiciary, in this context, has the responsibility to realize, with the jurisdic- tional activity, constitutional values ​and purposes, which sometimes may represent judicial activism, especially when it becomes necessary to inter- fere in the sphere of action of the other branches. Therefore, the notion of activism, so as rupture of positivist formalism, appears as a beneficent hermeneutical method in favor of the effectiveness of constitutional pro- visions, as long as pre-defined standards are stablished for the perfor- mance of the judge, thus avoiding imbalances in the institutional frame that is immanent to contemporary democracies. The article proposes a reflection on judicial activism in the brazilian experience, highlighting the methodological effort to build hermeneutics that is, at once, committed to the legal effectiveness of the Constitution and linked to the institutio- nal framework of a constitutional democracy. The dangers camouflaged in the adoption of conservative interpretative technique are illustrated – although in a reductionist way – in the figure of the seven deadly sins, emphasizing the importance of motivated decisions to overcome, without ignoring the constitutional axiology, the thin line between auspicious ac- ting and ideological voluntarism.
