The Superior Court of Justice is highest organ of the Judiciary in Brazil. It describes how a task is to ensure uniformity of interpretation of the Brazilian federal legislation.
The Supreme Court is also called the “Court of Citizenship”, for its origin in the “Citizen Constitution”. It is STJ’s responsibility to judge, ultimately, all unspecialized infraconstitutional matters that are beyond the Labor Courts, Electoral and Military, and not dealt with in the Constitution, as the trial of issues that relate to the application of federal law or divergence of judicial interpretation. In the first case, the Court shall examine the appeal if a lower court denied the application of federal law article. In the second case, the Supreme Court acts in the standardization of interpretation of the decisions of the lower courts; that is, if noting that the interpretation of federal law of a lower court is divergent from another Court (including the Supreme Court itself), the Supreme Court can review the issue and unify interpretation.
