Ativismo judicial no Sistema Tributário Nacional: interpretação do aspecto material das regras de competência

Abstract

This workhas the intent to analyze the judicial control over the tax rules, criticizing the activism and privileging the constitucional interpretation by parlament. In brazilianconstitucional jurisdiction, several reasons increase judiciary among other powers: constitucionalism, with recognition of normative strength of constitucion, the legal type doctrine in tax law, the definite rule of tax competence, the vagueness language in constitucion, among others. Consequently, it is commom that the Supreme Court declares unconstitucionality of laws by its own concecptions, as if taxation system were completely on constitucion, and were not formed by law as well. There will be presented some alternatives for that such as: constitucional dialogues, judicial restraint, methodological plurality in spite of single criteria of interpretation, constitucionalconcepcts with semantic content surrounded by a marginal meaning, and creative role of legislative discretion in interpretation of competence rules in constitucion.
