Are Shapiro v. Thompson and Schenck v. United States both US Supreme Court cases?
Schenck v. United States Schenck v. United States, 249 U.S. 47 (1919) , is a United States Supreme Court case concerning enforcement of the Espionage Act of 1917 during World War I. A unanimous Supreme Court, in an opinion by Justice Oliver Wendell Holmes, Jr., concluded that defendants who distributed fliers to draft-age men, urging resistance to induction, could be convicted of an attempt to obstruct the draft, a criminal offense. The First Amendment did not alter the well-established law in cases where the attempt was made through expressions that would be protected in other circumstances. In this opinion, Holmes said that expressions which in the circumstances were intended to result in a crime, and posed a "clear and present danger" of succeeding, could be punished.
Youngstown Sheet &amp; Tube Co. v. Sawyer Youngstown Sheet & Tube Co. v. Sawyer, 343 U.S. 579 (1952) , also commonly referred to as The Steel Seizure Case, was a United States Supreme Court decision that limited the power of the President of the United States to seize private property in the absence of either specifically enumerated authority under Article Two of the United States Constitution or statutory authority conferred on him by Congress. It was a "stinging rebuff" to President Harry Truman.
