This is a list of cases reported in volume 260 of United States Reports, decided by the Supreme Court of the United States in 1922 and 1923. Justices of the Supreme Court at the time of volume 260 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 260 were decided the Court comprised the following nine members: Notable cases in 260 U.S. Zucht v. King In Zucht v. King, 260 U.S. 174 (1922), the Supreme Court held that the school district of San Antonio, Texas, could constitutionally exclude students not vaccinated against smallpox from attending schools in the district. This followed the Court's 1905 ruling in Jacobson v. Massachusetts, in which the Court "had settled that it is within the police power of a state to provide for compulsory vaccination". Ozawa v. United States In Ozawa v. United States, 260 U.S. 178 (1922), the Supreme Court found Takao Ozawa, a Japanese-American who was born in Japan but had lived in the United States for 20 years, ineligible for naturalization. In 1914, Ozawa had filed for US citizenship under the Naturalization Act of 1906. This act allowed only "free white persons" and "persons of African nativity or persons of African descent" to naturalize. Ozawa did not challenge the constitutionality of the racial restrictions. Instead, he claimed that Japanese people should be properly classified as "free white persons". The Court held that "the words 'white person' was only to indicate a person of what is popularly known as the Caucasian race", and so Japanese were not considered "free white persons" within the meaning of the law. Yamashita v. Hinkle In Yamashita v. Hinkle, 260 U.S. 199 (1922), the Supreme Court upheld the constitutionality of the state of Washington's Alien Land Law. The law prohibited Asians from owning property. Washington's attorney general
