The research hereto intends to analyse consistency of the legal order or the duty of legislative consistency (Folgerichtigkeit), as a part of the understanding the Law as a system, in order to (I) understand, define and demonstrate the fundamentals of the the duty of legislative consistency and (II) to demonstrate the implementation of the duty legislative consistency in tax law, applying its control mechanisms. To achieve the goal to delimit and demonstrate the fundamentals of the constitutional duty of legislative consistency, are facing three major issues: 1) is the definition of legislative consistency, analyzing its development, its dimensions of effectiveness, its contrast with similar institutes, proving to be a complex legislative consistency standard can be employed to guide the legislator in the preparation of standards in attention to relations of new standards with the pre-defined already by him (legislative consistency postulate) , to achieve the ideal of distributive justice by requirement continues to pursue the egalitarian distribution of privileges and the tax burden (legislative-consistency principle), as limited to the power to legislate by imposing the elaboration of consistent laws and free of unjustified discrimination (legislative consistency-rule) and also as a criterion for evaluation of normative content material compatibility (legislative consistency-criterion). Its Foundation is given by deriving from the rule of law and legislation and equality. Through it we need the Legislature to autovinculação so that the more intensely it has set an Institute, the higher your burden of justification for deviating from the duty of legislative consistency. Secondly the duty of legislative consistency is applied to the tax law, through the control of equality and a systematic approach. As for example apply these controls for the non-cumulative PIS and COFINS inserted specifically in relation to two issues: (1) the imposition of restriction on crediting, realizing the legislative inconsistency in that the purpose of the standard and how it has been implemented are not consistent and (2) the discrímen criteria for imposition of cumulative or non-cumulative regime the given contributor. Also in this case there is legislative inconsistency.
