National Treasury Employees Union v. Von Raab

National Treasury Employees Union v. Von Raab 489 U.S. 656 (1989) was a United States Supreme Court case involving the Fourth Amendment and its implication on drug testing programs. The majority of the court upheld the drug testing program in United States Customs Service.

Background
In 1986, the U.S. Customs Service imposed a drug testing program for "employees seeking transfer or promotion to positions having direct involvement in drug interdiction," required to carry firearms, or have access to classified information. The National Treasury Employees Union sued and alleged that the program was violative of the Fourth Amendment, which prohibits unreasonable search and seizure. The Court of Appeals for the Fifth Circuit ruled in favor of the government. The union then appealed to the Supreme Court. The Supreme Court upheld the Court of Appeals ruling with regard to positions involving drug interdiction and firearms. The ruling for classified information was held over, as the Supreme Court determined that the U.S. Customs Service too broadly included employee groups who would not generally have access to high levels of classified information.

Decision
The majority decision authored by Justice Anthony Kennedy upheld the constitutionality of the drug testing program, reasoning that the employees of customs service had "diminished expectation of privacy." Justice Marshall wrote a dissent in which he was joined by Justice Brennan; Justice Scalia wrote a dissent in which Justice Stevens joined.
