Youngstown Sheet & Tube v. Sawyer (1952)
President Truman ordered the federal government to seize steel mills to prevent a strike he said would cripple Korean War production. He cited his powers as commander in chief without explicit congressional authorization.
The Supreme Court ruled 6–3 that the president lacked authority to seize private industry, and operations returned to the companies.
Youngstown became a foundational precedent limiting presidential power, establishing that the executive cannot manufacture emergencies to override statutes.
Like Youngstown, this case tests whether an administration can use emergency powers to force private industry to act against approved plans and established law.
