The Supreme Court of the USA

The US Supreme Court is the highest judicial and supreme judicial organ of the US federal court system and is the only federal court stipulated by the Constitution. In 1869, according to the Congressional Decree, the Chief Justice consisted of one person and eight judges, and served for a lifetime. One of the nine justices is the chief justice of the United States. The Federal Supreme Court has the power to rule that any law in the federal and state, and states that is unconstitutional or not adopted.

One of the great advantage of the US Supreme Court is they can modify law base on the actual events. Therefore, the law or bill they announced is practical and changeable. For instance, after the case of Plessy in 1896, the Supreme Court assumed the doctrine of "separate but equal", and we all know what unfair society that American Africans had faced for the half of the century until Brown v. Board of Education in 1954. The Supreme Court cannot make the correct choice all the time, but it would always be a shield of the American.
