Generally, unless there is an applicable exception, both the Washington and U.S. constitutions require a warrant supported by probable cause before someone acting on behalf of the government can conduct a search. One exception to the warrant requirement applies to school officials. Under the school search exception, a school official may conduct a reasonable search of a student. This does not mean a school can search any student at any time for any reason—the search must be reasonable. Washington criminal courts use the “McKinnon Factors” to determine if a school search was reasonable.
A defendant challenged her conviction on the grounds the search was unlawful. According to the appeals court opinion, the school received information about a threat involving the juvenile defendant, who was not a student of that school. Staff looked her up in the school district’s system so they could identify her. When the vice principal saw her, he asked her to come into the office.
In the office, the principal asked the defendant why she was there. After a few minutes, the principal determined she was uncooperative and told her they were calling the police. The vice principal testified the defendant would have been allowed to leave if she had chosen to do so. He also testified they did not have the authority to discipline her since she was not a student at their school.
