Which case introduced the 'clear and present danger' test for free speech?

• A. Schenck v. United States (1919)
• B. Dennis v. United States
• C. Abrams v. United States
• D. Whitney v. California

Answer: (A)

The main idea here is the origin of the clear and present danger standard used to limit free speech in certain circumstances. In Schenck v. United States (1919), the Supreme Court first articulated that when speech creates a clear and present danger of bringing about evils that the government has a right to prevent, the First Amendment does not shield it. The case involved pamphlets opposing the WWI draft; the Court reasoned that distributing material that would obstruct conscription could pose a real, immediate risk to the war effort, so restricting that speech was permissible. This set the standard judges use to weigh whether speech can be curtailed in times of war or other crises.

That’s why this option is the best answer. The other choices either come after Schenck or deal with related but different contexts: Dennis v. United States applies the doctrine to advocacy of revolution but is not the origin of it; Abrams v. United States is a contemporaneous case with a dissent that criticized the approach; Whitney v. California concerns criminal syndicalism rather than establishing the standard itself.
