1. Intentionally gather or intentionally remain assembled outside any university building in such numbers, in such proximity to each other or in such fashion as to physically hinder entrance to, exit from, or normal use of the building.
2. Intentionally congregate or assemble within any university building in such fashion as to obstruct or seriously impair university−sponsored or university−authorized activities, or in such fashion as to violate any of the following conditions:
a. No group may be admitted into the private office of any faculty member or other university employee unless invited by the authorized occupant of that office, and then not in excess of the number designated or invited by that person.
b. No group may obstruct or seriously impair passage through corridors, stairways, doorways, building entrances, fire exits, and reception areas leading to offices.
c. No group, not authorized to do so by the person in immediate charge of the room, or by a person designated by the chief administrative officer to approve requests for the use of rooms for meetings, may enter or occupy any university building or part thereof.
d. No group may assemble immediately outside rooms at times when they are normally in use for classes, study, or research.
