Gilbert v. Minnesota
The Court upheld a Minnesota law making it a crime to speak against military enlistment or urge citizens not to aid the war effort, ruling that states share the nation's interest in maintaining morale for war and can police such speech without invading Congress's exclusive war powers.
The decision also held that free speech, though a fundamental right, is not absolute during wartime, applying the same reasoning the Court had recently used to uphold convictions of war critics under the federal Espionage Act.
“An army is an instrument of government, a necessity of its power and honor, and it maybe, of its security.”

How it got here: A Minnesota trial court convicted Gilbert after his demurrer was overruled; the Minnesota Supreme Court affirmed, and he brought the case to the U.S. Supreme Court on federal constitutional grounds.
The Case in Depth
What happened
Joseph Gilbert, an organizer for the Non-partisan League, gave a public speech in Minnesota in 1917 questioning American democracy, criticizing the draft, and suggesting the country had been misled into the war. He was prosecuted under a Minnesota law that made it a crime to discourage military enlistment or advocate against supporting the war effort, and was convicted and sentenced to a fine and a year in jail.
The question before the Court
During World War I, could Minnesota criminally punish a man for giving a speech urging people not to support the war effort or the draft?
Why it matters
The ruling meant states could pass their own laws punishing anti-war and anti-draft speech during World War I, on top of federal sedition laws, giving both state and federal governments overlapping power to prosecute war critics. It reinforced a narrow view of free-speech protections during wartime that shaped how governments treated dissent for years afterward.
What changes now
This was a final decision on the merits, so Gilbert's conviction and sentence stood. The ruling let Minnesota's wartime speech law remain in force and signaled that state laws punishing anti-war speech could coexist with federal sedition laws. No further proceedings were ordered, though the case became part of a series of decisions from this era addressing how far governments could go in restricting speech critical of World War I.
What this does not decide
The Court did not decide whether the federal Espionage Act displaced or conflicted with the Minnesota law, nor did it resolve whether free speech is fully protected by the Constitution — it assumed the right existed without deciding that question, focusing instead on whether it was absolute.
Concurrences and dissents
How the Justices voted
Majority (1). Justice McKenna (author).
Dissent (1). Justice Brandeis (author).
Concurrence — Justice Holmes
Justice Holmes agreed with the outcome upholding Gilbert's conviction but did so only 'in the result,' without joining the majority's reasoning about state war powers or endorsing its broader analysis. The opinion text gives no further explanation of his separate view.
Dissent — Justice White
The Chief Justice dissented on the ground that regulating discouragement of enlistment and support for the war is a subject within Congress's exclusive legislative power, and that Congress, by enacting the Espionage Act and related wartime legislation, had already occupied that entire field, leaving no room for state regulation.
Dissent — Justice Brandeis
“In frank expression of conflicting opinion lies the greatest promise of wisdom in governmental action; and in suppression lies ordinarily the greatest peril.”Brandeis's warning that suppressing dissenting speech, even in wartime, endangers sound government.
Justice Brandeis argued the Minnesota law was not truly a peace-preserving police measure but an attempt to suppress the teaching of pacifism at all times, not just during a declared war. He reasoned that Congress alone controls enlistment and war conduct, that federal law left citizens free to advise against enlistment, and that the state law directly invaded a citizen's federally protected right to discuss and criticize government war policy, making it invalid regardless of the police-power label attached to it.

How the Court got there
The legal reasoning, step by step
- The Court first asked whether regulating this kind of speech belonged exclusively to Congress because only Congress can declare war and raise armies. It reasoned that even though only the federal government can raise and direct an army, states are made up of the same citizens who serve in it, so states share a real interest in maintaining the public morale needed to support the war effort.
- Drawing on an earlier case upholding a state law against commercial misuse of the American flag, the Court reasoned that a state fostering patriotism toward the nation is also fostering patriotism toward itself, so the state and federal interests overlap rather than conflict.
- Because the statute did not attempt to raise, arm, or direct troops but only restrained citizens from discouraging enlistment and undermining the war effort, the Court concluded it did not intrude on Congress's exclusive powers, and it also viewed the law as a legitimate use of the state's police power to prevent public disorder, noting that Gilbert's speech had in fact provoked angry, near-violent reactions from his audience.
- Turning to free speech, the Court assumed without deciding that free speech is a natural, inherent right, but held that such a right is not absolute and can be limited, citing its recent wartime decisions holding that the First Amendment does not protect every use of language, especially speech that creates a danger during a declared war.
- Applying that limited-protection principle to the facts, the Court found that Gilbert's speech was aimed squarely at discouraging citizens from supporting a war that had been properly declared, that his statements misrepresented the government's motives, and that this fell outside any right the Constitution protects, so his conviction did not violate his free-speech rights.
