Locker Search Policy

  • Saint Louis University and Pius XII Memorial Library reserve the right to conduct a locker search for the reasons outlined in the “Regulations” section above or when it has been determined, at the discretion of appropriate Pius Library officials, that sufficient cause exists. The Dean of Libraries, Chair of Research and Instruction, and the Patron Services Coordinator will make this determination. After proper authority has been granted, the search will be conducted in the following manner:

    • Two Pius Library staff members will conduct the search.
    • In most cases, the persons conducting the search will obtain the locker combination from the signed student agreement in circulation services.
    • Students will be informed by email of the purpose of the search. Students are not required to be present unless requested by staff. If so requested, students must remain with the library staff members near the locker or under staff supervision. Searches may be conducted in the students’ absence.
    • All areas and spaces of the locker and all objects and containers within the locker may be searched. Illegal or unauthorized items will be confiscated, and locker owners will be provided with a list of these items taken. Items violating local, state or federal laws may be turned over to law enforcement authorities.
    • Department of Public Safety and Emergency Services or police officers with proper authority may initiate a search within standard legal guidelines. These procedures may supersede the above guidelines. The information gathered during this process may be processed through the conduct board.
