The purpose of the Student Judiciary is to uphold the dignity of the FIU Student Constitution. This section of student government is made up of a Chief Justice and four confirmed Justices (which includes an Assoc. Chief Justice and an Assoc. Parliamentarian). The Student Judiciary works as a High Court to determine whether actions taken by the SGC (Student Governing Council) are within the boundaries set by the Constitution. In addition, the Student Judiciary works to maintain the constitutionality of Senate legislation and bylaws.

The Student Judiciary also serves as a neutral and impartial internal standards board for the SGC members, and protects proper division of SGA powers between branches (Executive, Legislative, & Judicial).

Similar to the United State's Supreme Court, the Student Judiciary remains the chief agent for interpretation of the SGA Constitution, as well as a legal aid to the SGC regarding issues of interpretation. In addition, the Chief Justice serves as the SGC’s Parliamentarian to aid in questions and concerns regarding Parliamentary Procedure.
