The case arose from a 1980 incident at Piscataway High School in New Jersey, where a female student, TLO, was suspected of smoking in the girls' bathroom. A school official, Vice Principal Theodore Choplick, searched TLO's purse without her consent and discovered cigarettes, marijuana, and drug paraphernalia.
The student was subsequently charged with possession of marijuana and related offenses. TLO filed a motion to suppress the evidence obtained during the search, arguing that it violated her Fourth Amendment rights against unreasonable searches and seizures. The New Jersey Supreme Court initially ruled in favor of TLO, holding that the search was unconstitutional because it was not based on reasonable suspicion.
However, the U.S. Supreme Court overturned the New Jersey Supreme Court's decision in a 6-3 ruling. The Court held that the Fourth Amendment applies to public schools, but the standard for conducting searches in schools is different from that for searches conducted by law enforcement officers.
The Supreme Court established a lower standard of reasonableness for searches in schools, balancing the need for student safety and privacy. Under the "reasonable suspicion" standard, a school official may search a student without a warrant if they have a reasonable suspicion that the student is engaging in illegal activity or that the search is necessary to maintain school discipline or safety.
In the case of TLO, the Court found that Vice Principal Choplick's search was reasonable because he had reasonable suspicion that TLO was smoking in the bathroom and that the search was necessary to maintain school discipline.
The Court also noted that the search was conducted in a reasonable manner, as Choplick searched the student's purse in private, rather than in public, and the search was not overly intrusive or humiliating.
The TLO decision set an important precedent for the balance between student privacy rights and the need for maintaining order and safety in public schools. While it clarified that the Fourth Amendment does apply to schools, it also provided school officials with greater authority to conduct searches in certain situations.
