Quick Answer: The 1937 court-packing plan was President Franklin D. Roosevelt's proposal to add up to six new justices to the U.S. Supreme Court after a series of New Deal rulings went against him. The plan was introduced on February 5, 1937, and ultimately failed in Congress.

Key Facts

Overview

The 1937 court-packing plan was a controversial legislative proposal by President Franklin D. Roosevelt to expand the number of justices on the U.S. Supreme Court. Roosevelt introduced the plan in response to the Court repeatedly invalidating major components of his New Deal economic recovery programs.

Despite Roosevelt’s landslide re-election in 1936, the Supreme Court—led by conservative justices—struck down key legislation like the National Industrial Recovery Act (NIRA) and the Agricultural Adjustment Act (AAA). Frustrated by judicial obstruction, Roosevelt sought structural reform to secure favorable rulings.

How It Works

Roosevelt’s Judicial Procedures Reform Bill of 1937 introduced a mechanism to increase the number of Supreme Court justices based on age and tenure.

The court-packing plan failed legislatively, but its political pressure may have influenced the Court’s shift in 1937, known as “the switch in time that saved nine.” Justice Owen Roberts began voting to uphold New Deal laws, reducing the need for reform. Over time, natural retirements allowed Roosevelt to reshape the Court without changing its size.

Why It Matters

The 1937 court-packing plan remains a pivotal moment in U.S. constitutional history, illustrating the tension between the executive and judicial branches. Though unsuccessful, it sparked lasting debate about judicial independence, court reform, and presidential power.

Ultimately, the 1937 court-packing plan failed as legislation but succeeded politically by prompting a judicial shift that preserved New Deal reforms and redefined federal power in the 20th century.
