This document summarizes the case of New Jersey vs. T.L.O., a 14-year old high school student who was caught smoking cigarettes in the bathroom. When brought to the principal's office, a search of her purse revealed marijuana and paraphernalia. Lower courts disagreed on whether the search violated the student's Fourth Amendment rights. The Supreme Court ultimately ruled that while students have privacy rights, the search in this case was not unreasonable given the circumstances.
