Pierce, Governor of Oregon, et al. v. Society of the Sisters of the Holy Names of Jesus and Mary, 268 U.S. 510 (1925), was an early 20th-century United States Supreme Court decision striking down an Oregon statute that required all children to attend public school. The decision significantly expanded coverage of the Due Process Clause in the Fourteenth Amendment to the United States Constitution to recognize personal civil liberties. The case has been cited as a precedent in more than 100 Supreme Court cases, including Roe v. Wade, and in more than 70 cases in the courts of appeals.
