Here are some excerpts from the University of Illinois at
Urbana-Champaign's Code on Campus Affairs and Regulations
Applying to All Students (Aug. 1985)

"STATEMENT ON INDIVIDUAL RIGHTS
 I. Preamble
 A student at the University of Illinois at the Urbana-Champaign campus
 is a member of the University community of which all members have at
 least the rights and responsibilities common to all citizens, free from
 institutional censorship;"

 ...

"III. Campus Expression
 A. Discussion and expression of all views is permitted within the
 University subject only to requirements for the maintenance of order.
  [...]
 B. Members and organizations in the University community may invite
 and hear any persons of their own choosing, subject only to reasonable
 requirements on time, place, and manner for use of University facilities.
 C. The campus press and media are to be free of censorship. The editors
 and managers shall not be arbitrarily suspended because of student,
 faculty, administration, alumni, or community disapproval of editorial
 policy or content."

...

"IV. Privacy

A. Members of the University community have the same rights of
privacy as other citizens and surrender none of those rights by
becoming members of the academic community. These rights of privacy
extend to residence hall living. Nothing in University regulations or
contracts shall give University officials authority to consent to a
search by police or other government officials of offices assigned or
living quarters leased to individuals except in response to a properly
executed search warrant or search incident to an arrest.

B. When the University seeks access to an office assigned or living
quarters leased to an individual to determine compliance with
provisions of applicable multiple-dwelling unit laws, ordinances, and
regulations, or for improvement or repairs, the occupant shall be
notified of such action not less that twenty-four hours in advance.
There may be entry without notice in emergencies where imminent
danger to life, safety, health, or property is reasonably feared and
for custodial service.

C. The University may not conduct or permit a search of an office
assigned or living quarters leased to an individual except in
response to a properly executed search warrant or search incident to
an arrest."


 ...

"VI. Student Affairs 
 [...]
 B. Freedom of Inquiry and Expression
 1. Students and student organizations should be free to examine and to
 discuss all questions of interest to them, and to express opinions
 publicly and privately. [...]
 2. Students should be allowed to invite and hear any person of their
 own choosing. [...] The University's control of campus facilities should
 not be used as a device of censorship. It should be made clear to the
 academic and larger community that sponsorship of guest speakers
 does not necessarily imply approval or endorsement of the views expressed
 either by the sponsoring group or the institution."
