The president appoints all federal judges, including the justices of the Supreme Court, for a life term. The American Bar Association, the national organization of attorneys, rates candidates for the federal bench on a scale ranging from "exceptionally well qualified" to "not qualified." However, the president is under no obligation to pay any attention to the ratings. Federal judges are confirmed by a majority vote of the Senate, often following hearings before the Senate Judiciary Committee. Federal judges may be impeached and removed from office if found guilty of the charges. Judges in the district courts and courts of appeal are required to live within the geographical boundaries of their courts.
