Executive Order 10340

Executive Order 10340 was the instrument through which Harry S. Truman ordered the federal government to take over the steel plants in April 1952, just hours before a scheduled strike. He defended the action as a temporary last resort to keep production running, but the steel companies challenged it in court. The Supreme Court’s 6–3 ruling against the seizure made the order a defining test of the limits of presidential power in a labor emergency.

Crisis and rationale

The order arose from a dispute over steel prices and a threatened shutdown during an accelerated defense program. Truman believed the companies’ proposed price increases would undermine his anti-inflation policy and increase the cost of the government’s defense purchases. The government, he emphasized, was by far the largest customer for steel and steel products. In his view, raising prices under those circumstances meant charging the public more for the materials needed for defense.

Truman acknowledged that a modest increase of $4.50 might be tolerable, but rejected the industry’s demands. His position was not simply an endorsement of the steelworkers’ claims: he was also acting on a longstanding distrust of large corporations and his belief that the companies were trying to force a compromise by threatening to stop production. Charles E. Wilson, Truman’s director of defense mobilization, considered the industry’s position valid. Truman went over Wilson’s head; Wilson resigned, a consequence Truman regretted and which intensified criticism of the President.

The approaching strike made the disagreement immediate. Truman regarded taking control of the mills as a temporary measure of last resort, rather than a permanent transfer of ownership. On April 8, only hours before the plants were scheduled to be struck, he signed Executive Order 10340. That night, at 10:30, he addressed the country and said the government would take over the steel plants at midnight. He presented the move as a presidential duty to prevent what he described as a reckless shutdown and to keep steel production going.

Public defense and question of scope

Truman’s announcement framed the order as an emergency response to a threatened interruption of production. Its justification rested on the immediate stakes: steel was central to the defense program, the government was its largest customer, and a shutdown risked disrupting production while the country was mobilizing for defense. His insistence that the takeover was temporary distinguished the measure, in his account, from an attempt to make the plants government property permanently.

The asserted authority nevertheless raised a broader question about what a President could do in the name of the national interest. At a press conference, Truman was asked whether the same reasoning might allow him to seize newspapers and radio stations. He answered that under similar circumstances the President had to act in whatever way was best for the country. The response was imprudent and stirred speculation that he might seek control of the press, although the account makes clear that such a proposal had not occurred to him and was unimaginable to him. The exchange exposed the risk in defending an emergency measure through a broad claim of presidential discretion: an explanation intended to justify one intervention could sound like a warrant for others.

Truman said he had no ambition to be a dictator and wanted only to keep the country running. He also told reporters he would abide by the Court’s decision. Those assurances did not settle the constitutional issue. The case turned on whether the President could use executive authority, including his role as Commander in Chief, to take private property in order to prevent a labor dispute from stopping production.

Court challenge and ruling

The steel industry sued to recover its property. Federal district judge David A. Pine ruled the seizure illegal, rejecting the claim that the threatened strike justified an unlimited and unrestrained executive power. His opinion weighed the threatened harm from a strike against the constitutional danger of judicially recognizing such a broad claim. Truman read the opinion repeatedly but could not understand why the court had found him wrong. He told Secretary of Commerce Sawyer that he would be deeply shocked and disappointed if the Supreme Court reached the same conclusion.

The Supreme Court heard the case, and on June 2 ruled 6–3 against the President. Justice Hugo Black’s majority opinion held that the Commander in Chief did not have ultimate power, by virtue of that role, to take possession of private property to keep labor disputes from stopping production. The opinion placed such a decision with the nation’s lawmakers, not its military authorities. The majority therefore rejected the central constitutional basis for the takeover, despite the emergency and production concerns Truman had invoked.

Justice William O. Douglas, writing separately, stressed the danger of allowing a power that might appear benign in one instance to become a tool of oppression in another. A President might seize mills to keep furnaces operating or to secure a wage increase; a future President might use the same claimed power to prevent wage increases, curb unionists, or regiment labor. Chief Justice Vinson dissented, joined by Justices Stanley F. Reed and Sherman Minton. He argued that a President should be able to take interim action necessary to carry out legislative programs essential to the nation’s survival, and emphasized that the takeover was temporary and subject to congressional approval, disapproval, or regulation.

Significance and limits

Executive Order 10340 did not resolve the steel dispute by establishing a lasting presidential power to take over private industry. Instead, the litigation forced a direct examination of the distinction between responsibility for national defense and constitutional authority over private property. Truman had acted on his view that preventing a shutdown was necessary; the Supreme Court held that the need to maintain production did not, by itself, give the Commander in Chief the power to seize the mills to settle a labor emergency.

The episode also brought together two strands of Truman’s conduct described in the book. In his Senate work, he had argued that control of the war effort must remain in civilian hands rather than pass to military leaders. In the steel crisis, he likewise asserted a strong executive role, but the Court’s decision made clear that presidential responsibility did not erase constitutional limits or Congress’s place in making law. The order’s significance thus lies both in the emergency action it authorized and in the judicial boundary that followed: the President’s determination to keep the country running could not substitute for authority the Constitution had not granted.
