On June 27, 2002, the Supreme Court upheld the right of school districts to conduct random drug testing of students, as part of their efforts to detect and prevent illegal drug use. The decision was a victory for WLF , which filed a brief in the case in support of an Oklahoma school district whose drug testing program was challenged by the ACLU. The Court agreed with WLF that school districts should not be required to prove that drug use is rampant before instituting a testing program for students wishing to participate in extracurricular activities. WLF filed the brief on behalf of Oklahoma Governor Frank Keating as well as 30 residents of the Oklahoma school district.
