Schenck v. United States

Background

A leader of the Socialist Party and a member of its Executive Board were tried for mailing and distributing leaflets that criticized the draft. They were indicted in three counts under the 1917 Espionage Act: conspiring to cause insubordination in the military and to obstruct recruiting and enlistment, conspiring to mail matter declared non-mailable, and unlawfully using the mails. The record showed thousands of leaflets were printed and mailed to men called for service, and the defendants were convicted on all counts.

Reasoning

The central question was whether the First Amendment’s protection of speech barred conviction for circulating these leaflets. The Court said the answer depends on the circumstances and the effect of the words. It held that speech that, in context, creates a "clear and present danger" of bringing about harms the government may prevent is not protected. The opinion compared such dangerous speech to falsely shouting fire in a crowded theater and emphasized that wartime conditions can make otherwise lawful words a punishable hindrance to the nation’s military effort. The Court therefore affirmed the convictions.

Real world impact

The ruling permits the government to prosecute and punish speech that tends to obstruct military recruitment or enlistment during wartime. It narrows free-speech protections in contexts where words are likely to produce immediate and serious harm to the nation’s war efforts, and it upholds criminal liability for using the mails to distribute such material.
