List of United States Supreme Court cases, volume 274

This is a list of cases reported in volume 274 of United States Reports, decided by the Supreme Court of the United States in 1927.

Justices of the Supreme Court at the time of volume 274 U.S.
The Supreme Court is established by Article III, Section 1 of the Constitution of the United States, which says: "The judicial Power of the United States, shall be vested in one supreme Court . . .". The size of the Court is not specified; the Constitution leaves it to Congress to set the number of justices. Under the Judiciary Act of 1789 Congress originally fixed the number of justices at six (one chief justice and five associate justices). Since 1789, Congress has varied the size of the Court from six to seven, nine, ten, and back to nine justices (always including one chief justice).

When the cases in volume 274 were decided the Court comprised the following nine members:

Buck v. Bell
In Buck v. Bell, 274 U.S. 200 (1927), the Supreme Court ruled that a state statute permitting compulsory sterilization of the unfit, including the intellectually disabled, "for the protection and health of the state" did not violate the Due Process Clause of the Fourteenth Amendment to the United States Constitution. Despite the changing attitudes in the coming decades regarding sterilization, the Supreme Court has never expressly overturned Buck v. Bell. It was widely believed to have been slightly weakened by Skinner v. Oklahoma 316 U.S. 535 (1942), which involved compulsory sterilization of male habitual criminals (and came to a contrary result).

Whitney v. California
In Whitney v. California, 274 U.S. 357 (1927), the Supreme Court upheld the conviction of a person who had engaged in speech that raised a threat to society. The question before the court was whether the 1919 Criminal Syndicalism Act of California violated the Fourteenth Amendment's Due Process and Equal Protection Clauses. The Court unanimously upheld Whitney's conviction; holding that the state, in exercise of its police power, has the power to punish those who abuse their rights to freedom of speech "by utterances inimical to the public welfare, tending to incite crime, disturb the public peace, or endanger the foundations of organized government and threaten its overthrow." In other words, words with a "bad tendency" can be punished.

United States v. Lee
United States v. Lee, 274 U.S. 559 (1927), is a significant decision by the Supreme Court protecting prohibition laws. The Court held 1) the U.S. Coast Guard may seize, board, and search vessels beyond the U.S. territorial waters and the high seas 12 miles outward from the coast if probable cause exists to believe that the vessel and persons in it are violating U.S. revenue laws, and 2) the Coast Guard's use of searchlights to view contents of a vessel on the high seas does not constitute a search and thus does not warrant Fourth Amendment protections; the use of a searchlight is comparable to the use of binoculars, and the courts have long held that use of binoculars by law enforcement is not prohibited by the Constitution.

Citation style
Under the Judiciary Act of 1789 the federal court structure at the time comprised District Courts, which had general trial jurisdiction; Circuit Courts, which had mixed trial and appellate (from the US District Courts) jurisdiction; and the United States Supreme Court, which had appellate jurisdiction over the federal District and Circuit courts—and for certain issues over state courts. The Supreme Court also had limited original jurisdiction (i.e., in which cases could be filed directly with the Supreme Court without first having been heard by a lower federal or state court). There were one or more federal District Courts and/or Circuit Courts in each state, territory, or other geographical region.

The Judiciary Act of 1891 created the United States Courts of Appeals and reassigned the jurisdiction of most routine appeals from the district and circuit courts to these appellate courts. The Act created nine new courts that were originally known as the "United States Circuit Courts of Appeals." The new courts had jurisdiction over most appeals of lower court decisions. The Supreme Court could review either legal issues that a court of appeals certified or decisions of court of appeals by writ of certiorari. On January 1, 1912, the effective date of the Judicial Code of 1911, the old Circuit Courts were abolished, with their remaining trial court jurisdiction transferred to the U.S. District Courts.
