The new Brazilian Civil Procedure Code instituted a model of binding precedents, to approach the legal system of common law countries. The legislator was already seeking the transformation of the STF and t he STJ of superior courts in supreme courts, with the transition from the exercises of the judgment control function in this case for assurance uniformity of interpretation of the law. So assumes special importance the duty of grounds, which is disciplined in article 489, allowing the management of binding system, with appropriate formation and application of the precedents. The article attempts therefore shed light on concepts inherent in the work with binding precedents, especially on those instilled in law by new Brazilian Civil Procedure Code, which are the ratio decidendi , the distinguishing and the overruling.
