Answer:
It is the head of the Judicial Branch of the federal government. 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.
Step-by-step explanation:
The Constitution of the United States is a carefully balanced document. It is designed to provide for a national government sufficiently strong and flexible to meet the needs of the republic, yet sufficiently limited and just to protect the guaranteed rights of citizens; it permits a balance between society’s need for order and the individual’s right to freedom. To assure these ends, the Framers of the Constitution created three independent and coequal branches of government. That this Constitution has provided continuous democratic government through the periodic stresses of more than two centuries illustrates the genius of the American system of government. The complex role of the Supreme Court in this system derives from its authority to invalidate legislation or executive actions which, in the Court’s considered judgment, conflict with the Constitution. This power of "judicial review" has given the Court a crucial responsibility in assuring individual rights, as well as in maintaining a "living Constitution" whose broad provisions are continually applied to complicated new situations.
