In 1927, the Supreme Court upheld the conviction of Charlotte Anita Whitney under California’s Criminal Syndicalism Act for helping to organize the Communist Labor Party of California. The Court’s majority opinion, written by Justice Sanford, is largely forgotten. What endures is the concurrence of Justice Louis D. Brandeis — the first Jewish Justice of the United States Supreme Court — joined by Justice Holmes. It is, by wide agreement, the single most important defense of free expression ever written by an American judge.

What the Statute Punished

California’s 1919 act defined “criminal syndicalism” as any doctrine advocating crime, sabotage, or “unlawful acts of force and violence or unlawful methods of terrorism” as a means of accomplishing industrial or political change. It made it a felony to organize, assist in organizing, or knowingly become a member of any group formed to advocate that doctrine.

Brandeis saw immediately what was novel and dangerous in this. The crime was not incitement, not conspiracy, not an attempted act:

“The novelty in the prohibition introduced is that the statute aims, not at the practice of criminal syndicalism, nor even directly at the preaching of it, but at association with those who propose to preach it.”

The defendant was punished, he wrote, “not for contempt, incitement or conspiracy, but for a step in preparation, which, if it threatens the public order at all, does so only remotely.”

Rights Are Fundamental, But Not Absolute

Brandeis did not claim speech is beyond regulation. He conceded that free speech and assembly “are not in their nature absolute,” and may be restricted where restriction “is required in order to protect the State from destruction or from serious injury, political, economic or moral.” But the necessity must be real, and the danger must be genuine:

“That the necessity which is essential to a valid restriction does not exist unless speech would produce, or is intended to produce, a clear and imminent danger of some substantive evil which the State constitutionally may seek to prevent has been settled.”

Crucially, he rejected the idea that a legislature’s say-so settles the question. A statute valid only if certain conditions exist cannot, by its own enactment, prove those conditions. The legislative declaration “creates merely a rebuttable presumption.” Courts retain the power to strike down the law — and that power, he insisted, “is no less when the interests involved are not property rights, but the fundamental personal rights of free speech and assembly.”

The Passage That Made It Famous

Brandeis then turned from doctrine to first principles, in language closer to civic philosophy than to legal analysis:

“Those who won our independence believed that the final end of the State was to make men free to develop their faculties… They believed liberty to be the secret of happiness and courage to be the secret of liberty… that the greatest menace to freedom is an inert people; that public discussion is a political duty.”

And his warning about the mechanics of repression, written in 1927, reads as a description of every subsequent century’s failures:

“They knew that order cannot be secured merely through fear of punishment for its infraction; that it is hazardous to discourage thought, hope and imagination; that fear breeds repression; that repression breeds hate; that hate menaces stable government; that the path of safety lies in the opportunity to discuss freely supposed grievances and proposed remedies; and that the fitting remedy for evil counsels is good ones.”

Then the sentence that changed American law:

“If there be time to expose through discussion the falsehood and fallacies, to avert the evil by the processes of education, the remedy to be applied is more speech, not enforced silence. Only an emergency can justify repression.”

Fear Is Not a Legal Standard

Brandeis was equally clear that public alarm cannot substitute for proof of danger:

“Fear of serious injury cannot alone justify suppression of free speech and assembly. Men feared witches and burnt women. It is the function of speech to free men from the bondage of irrational fears.”

He drew the distinctions that later courts would adopt wholesale: “The wide difference between advocacy and incitement, between preparation and attempt, between assembling and conspiracy, must be borne in mind.” Even advocacy of law-breaking, “however reprehensible morally,” cannot be punished where it “falls short of incitement and there is nothing to indicate that the advocacy would be immediately acted on.”

He added a proportionality requirement as well. Even an imminent danger cannot justify suppression “unless the evil apprehended is relatively serious”; among free men, “the deterrents ordinarily to be applied to prevent crime are education and punishment for violations of the law, not abridgment of the rights of free speech and assembly.”

Why He Concurred Anyway

Having written the most eloquent defense of speech in the U.S. Reports, Brandeis voted to affirm Whitney’s conviction. The reason was procedural, and he said so plainly. Whitney had argued the statute was unconstitutional as applied, but she had never asked the trial court or jury to decide whether a clear and present danger actually existed, and there was record evidence of a contemporaneous IWW conspiracy to commit present crimes. On a writ of error to a state court, the Justices were confined to “the particular claims duly made below, and denied.”

“Because we may not enquire into the errors now alleged, I concur in affirming the judgment of the state court.”

It is a lesson in itself: the strongest constitutional argument in the world is worth nothing if it is not properly raised and preserved in the record below.

The Afterlife of the Opinion

Whitney was expressly overruled in Brandenburg v. Ohio (1969), which adopted, in substance, the Brandeis standard — speech may be punished only where it is directed to inciting imminent lawless action and is likely to produce it. The concurrence has since been quoted in cases on campus speech, protest, boycotts, incitement, and hate speech.

Why It Matters Now

Brandeis, the first Jewish Justice, arrived at the Court after a bruising confirmation fight shadowed by antisemitism. He understood in his own life what it means to hold unpopular views and belong to a suspect group — and he built his doctrine to protect exactly that person. The protection cuts both ways, which is precisely the point.

For Jewish students, faculty, and communal organizations facing hostile campus climates, the Brandeis framework supplies the operative distinctions: advocacy is protected; incitement to imminent lawless action is not. Offensive speech is protected; targeted harassment, threats, and conduct that denies equal access to education are not. The answer to bad argument is better argument — but the answer to intimidation, exclusion, and unlawful conduct is enforcement of the law, which is a different question entirely.

Brandeis gave us both halves of that answer in a single opinion. Ninety-nine years later, the task is to apply them accurately.
