Which Supreme Court case concerned the question of whether the defendant had First Amendment right to free speech against the draft during World War I, and established the 'clear and present danger' rule?

• A. Brown v Board
• B. Schenck v US
• C. Gideon v Wainwright
• D. Miranda v Arizona

Answer: (B)

This question tests how the First Amendment is interpreted when the country is at war and the government needs to protect the war effort. In Schenck v. United States, the Supreme Court established the “clear and present danger” standard to determine when speech can be restricted. The case involved Charles Schenck circulating pamphlets urging opposition to the World War I draft. The Court held that his words were not protected because they created a real and immediate danger to the nation’s ability to conduct the war; restricting speech was permissible to prevent the harm.

The idea behind the rule is that free expression has limits when it poses a substantial risk of serious harm that the government has a right to prevent, especially in wartime. The context matters—time, place, and the likelihood of the harm influence whether speech crosses the line into unprotected expression.

Other cases mentioned deal with different constitutional issues—desegregation in education, the right to counsel, and police warnings during interrogations—so they don’t establish the standard for limiting wartime speech like this one does.
