New Jersey v. T.L.O. (1985)

The Fourth Amendment ban on unreasonable searches applied to those conducted by public school officials as well as those conducted by law enforcement personnel; however, the Court used the less strict standard of “reasonable suspicion” rather than “probable cause” to conclude that the search of a student’s purse by public school officials did not violate the Fourth and Fourteenth Amendments.

The case touched on constitutional principles including limits on rights and civic values including responsibility.
