Answer: All Justices are nominated by the President, confirmed by the Senate, and hold their offices under life tenure. Since Justices do not have to run or campaign for re-election, they are thought to be insulated from political pressure when deciding cases. Established by the United States Constitution, the Supreme Court began to take shape with the passage of the Judiciary Act of 1789 and has enjoyed a rich history since its first assembly in 1790. The Constitution states that Justices "shall hold their Offices during good Behaviour." This means that the Justices hold office as long as they choose and can only be removed from office by impeachment.
