New Jersey v. T.L.O.
Citation and Court
469 U.S. 325 (1985) — Supreme Court of the United States
Facts
A high school assistant principal searched a student’s (T.L.O.’s) purse after she was caught smoking in the bathroom. The search revealed cigarettes, marijuana, drug paraphernalia, and evidence of drug dealing. T.L.O. moved to suppress the evidence, arguing the warrantless search violated the Fourth Amendment.
Issue
Whether the Fourth Amendment’s prohibition on unreasonable searches and seizures applies to searches conducted by school officials, and if so, what standard of justification is required.
Holding
The Fourth Amendment applies to school searches, but school officials need only reasonable suspicion rather than probable cause; neither a warrant nor probable cause is required for a constitutional school search.
Rule / Doctrine
The special needs of the school environment — maintaining order and discipline — justify a reduced standard of constitutional protection. A school search is reasonable under the Fourth Amendment if (1) the search was justified at its inception (reasonable grounds to suspect evidence of a rule or law violation), and (2) the search was reasonably related in scope to the circumstances justifying the interference.
Significance
Applied the Fourth Amendment to schools while creating a lower threshold than probable cause. The “reasonableness” standard from T.L.O. has been applied across many special-needs contexts and is foundational for understanding how courts balance institutional needs against privacy rights.
