Which year is associated with the Supreme Court gaining control over its docket?

The year associated with the Supreme Court gaining substantial control over its docket is 1925. This milestone is particularly important because it marked the passage of the Judiciary Act of 1925, also known as the "Judges' Bill." This act allowed the Supreme Court to have greater discretion in selecting the cases it wished to hear, effectively giving the Court the authority to determine its own agenda.

Prior to this, the Court was often compelled to hear a large number of cases based on the mandatory appeals structure that existed. The 1925 Act shifted this to a more discretionary system, transforming how the Supreme Court operated and allowing it to focus on cases of significant legal importance or those that presented substantial constitutional questions. Consequently, the 1925 change played a critical role in shaping the contemporary role of the Supreme Court in the American judicial system.

By understanding this, students can appreciate the evolution of the Court's function and its implications for judicial authority in the United States.
