Mont. Code Ann. § 20-25-513

An authorized official of the university or college may not enter the room of a student located at an institution unless the official has given the student a notice in writing. An emergency such as a fire or a call for help or when there is probable cause to believe the occupant needs assistance is the only exception to the written notice requirement. In an emergency, evidence of a crime obtained as a result of the emergency entry may not be admissible in any court of law unless due process of law has been satisfied in obtaining the evidence.
