The Court and Constitutional Interpretation
"EQUAL JUSTICE UNDER LAW"-These words, written above the main entrance to the Supreme Court Building, express the ultimate responsibility of the Supreme Court of the United States. The Court is the highest tribunal in the Nation for all cases and controversies arising under the Constitution or the laws of the United States. As the final arbiter of the law, the Court is charged with ensuring the American people the promise of equal justice under law and, thereby, also functions as guardian and interpreter of the Constitution.
Congressional Research Service Report
When exercising its power to review the constitutionality of governmental action, the Supreme Court has relied on certain “methods” or “modes” of interpretation—that is, ways of figuring out a particular meaning of a provision within the Constitution. This report broadly describes the most common modes of constitutional interpretation; discusses examples of Supreme Court decisions that demonstrate the application of these methods; and provides a general overview of the various arguments in support of, and in opposition to, the use of such methods of constitutional interpretation.
