The Judiciary Act of 1925 (43 Stat. 936), also known as the Certiorari Act, was an act of the United States Congress which sought to reduce the workload of the Supreme Court of the United States.
Although the Judiciary Act of 1891 (which created the United States courts of appeals and rendered a small part of the Supreme Court's jurisdiction discretionary subject to grant of writ of Certiorari) had relieved pressure on the Supreme Court's docket, the court remained obliged to rule:
Nonetheless, the number of appeals was a one-way upward ratchet, and the Justices argued that the only way to fix the problem once and for all was to have the Court conduct virtually all of its business by way of act of Certiorari.
Pushed by Chief Justice and former President William Howard Taft, Congress passed the 1925 act, which rendered the majority of the Supreme Court's workload discretionary, by removing the possibility of direct appeal to the court in most circumstances. Henceforth, pursuant to §237(b) of the act, appellants would file petititions for writs of Certiorari with the Supreme Court, which would be accepted at the discretion of four of the nine Justices. "No longer did the Court have to hear almost every case an unhappy litigant presented to it. Instead, for the most part, the Court could select only those relatively few cases involving issues important enough to require a decision from the Supreme Court." [2]
