A visitor who fails or refuses to obey University of Oregon rules, or an ordinance, law, or regulation of the city, county or state, may be requested or ordered by a University official, designated by the President, to leave any part or all of institutionally-owned or controlled premises and to remain away therefrom until specifically authorized to return. Any visitor not complying promptly with such requests or orders will be liable to the legal consequences of such non-compliance including arrest and punishment for trespass and disorderly conduct.

In the event the President is unavailable to act personally or to appoint a deputy, and no written, standing delegation of authority covering the specifics of the situation exists, authority to act is delegated in the order listed to: the Senior Vice President and Provost; the Vice President for Finance and Administration; the Vice President for Research and Innovation.
