Board of Education of Pottawatomie County v. Earls (2002)
In this Fourth Amendment case, the Court ruled that a public school could require all students who participate in extracurricular activities to submit to drug testing. The Court held that, given the “nationwide epidemic of drug use,” the requirement was constitutional. It “reasonably serve[d] the School District's important interest in detecting and preventing drug use among its students” and did not violate the ban on unreasonable search and seizure.
The case touched on constitutional principles including limits on rights.
