To become a member of judicial branch of government, you need to be appointed by the president and endorsed by the senate. The judicial branch of government is a collage of courts and judges who interpret the constitution. The constitution has significantly given the congress the discretion to determine the look of the federal judiciary. Federal judges can only be impeached by the House of Representatives. The judges have no fixed terms but serve until they die or retire or be convicted by the senate. For more information visit http://www.whitehouse.gov/our-government/judicial-branch.
