Supreme Court Justice of the United States is the highest federal court of the United States.It can also hear certain “appeals” from state high appellate courts that involve a “federal question,” such as an issue involving a federal satue or arising under the Constitution of the United States.These are currently 9 justices on the supreme court:one chief and eight associate justices.The number of justices is set by congress and the actual justices are nominated by the president.Ironically there are no requirements given in the constitution for becoming a Supreme Court Justice.No age, experience, or citizenship rules exist.In fact, a supreme court justice does not need to even have a law degree.
