The Brazilian experience of democratic transition was distinguished by the adoption of a new Constitution that had an effective popular participation in the constitutional process. In this perspective, the citizenship notion has  assumed the commitment to the constitutionally effectiveness recognized and legally protected rights. The particularity of the Brazilian Constitution would be precisely its opening to a political-constitutional project to correct social and economic inequalities. The correct application of the law challenges the possibilities of consolidating Brazilian democracy. Every day, legal norms are questioned not only as to their existence, but, above all, as to their real possibility of social transformation. The legal professional, in the Brazilian context, must incorporate into the knowledge of the legal norm an ethical and political value capable of meeting society's expectations in the promotion of social justice.

Public sustainability policies:

In constitutional democracy, public power is committed to promoting public policies capable to transform the reality characterized by persistent social and economic inequalities.
