The Federal Supreme Court is the highest court system. The first court only had six justices. There have been nine court judges since 1869. The President selects the Justices and the Senate must approve. They can be a judge for life unless they resign, retire or are removed due to a conviction of a crime.
Justices consider all cases submitted.
However, they vote on which cases they will take under review. Four of nine justices is required to accept a case which is put onto the Courts Calendar. The Supreme Court has had an interesting history. US Government Site was developed by the Palese Web Team.
