"EQUAL JUSTICE UNDER LAW" - These words, written over the main entrance to the Supreme Court Building, express the Supreme Court of the United States' ultimate responsibility. The Court is the highest tribunal in the country for all matters and conflicts arising under the United States Constitution or statutes. As the final arbitrator of the law, the Court is tasked with assuring the American people of the promise of equal justice under law, and so serves as the Constitution's custodian and translator.
