Higher-education officials voted Friday to stiffen the student riot policy for Maryland’s public universities, making it possible for students to face expulsion for riot-related offenses even if they are not convicted in court of a crime.

The revised policy, approved unanimously by the University System of Maryland Board of Regents, allows a student accused of setting fires, damaging property or other crimes during a riot after a university event to be punished through the on-campus judicial process. Previously, a student could be punished only if convicted in state court.
