When approved in 1925, "the Judges Bill", as it was known, dramatically shrank the number of cases coming directly to the court, yet retained a mandatory oversight on cases which raised questions involving federal jurisdiction. It called for the circuit courts of appeals to have appellate jurisdiction to review 'by appeal or writ of error' final decisions in the district courts, as well as for the district courts of Alaska, Hawaii, Puerto Rico, China, the United States Virgin Islands, and the Panama Canal Zone. The circuit courts were also empowered to modify, enforce or set aside orders of the Interstate Commerce Commission, the Federal Reserve Board, and the Federal Trade Commission. The bill further provided that "A final judgment or decree in any suit in the highest court of a State in which a decision in the suit could be had, where is drawn in question the validity of a treaty or statute of the United States may be reviewed by the Supreme Court on a writ of error." Lastly, cases involving final decrees which brought into question the validity of a wide range of Federal or state treaties, would come to the Court by certiorari. Four justices would be required to vote affirmatively to accept petitions, which meant that the Court's agenda would now be controlled by "judicial review" and that thousands of cases clogging the dockets could now be cut to hundreds which met the new requirements.
