Schools may implement random drug testing upon students participating in school-sponsored athletics. Decided June 21, 1995 (argued March 28, 1995). Opinion of the Court: Antonin Scalia → go there Dissenting: O'Connor. Applied: the Fourth Amendment → go there Applied: the Fourteenth Amendment → go there Topic: Fourth Amendment rights. Vernonia School District 47J v. Acton, 515 U.S. 646 (1995), was a U.S. Supreme Court decision which upheld the constitutionality of random drug testing regimen implemented by the local public schools in Vernonia, Oregon. Under that regimen, student-athletes were required to submit to random drug testing before being allowed to participate in sports. During the season, 10% of all athletes were selected at random for testing. The Supreme Court held that although the tests were searches under the Fourth Amendment, they were reasonable in light of the schools' interest in preventing teenage drug use. Wiki link
