Background

In the United States, the Supreme Court has the final say concerning any law or dispute in the land. The decisions by the U.S. Supreme Court may not be appealed and become the law of the land the instant the opinions are made public by publication of the document. No other branch of the government has the absolute final say on any issue, legal or otherwise.

Further, members of the Supreme Court are not elected by the public but rather are appointed for life by the President and Senate and cannot be removed by less than a 2/3 vote of the United States Congress.

Statement

The United States Supreme Court powers are considered appropriate and essential. No other legal form or entity could exist superior to this system.
