A referendum should be held among Chinese University students to decide if the dormitory rules that led to the expulsion of two students should be changed, a legislator said yesterday. Cheung Man-kwong, who is a university board member and a graduate in 1978, said hostel management should allow a referendum among residents to decide the fate of the controversial rules. 'University students are adults and they should learn about self-administration,' Mr Cheung said. The provisional chairman of the university's Students' Union, Mak Kwan-wing, and the chairman of Chung Chi College's Students' Union, Louis Leung Ho-ming, said they seldom heard complaints about hostel rules. Most students accepted the rules as part of dormitory life, they said. Mr Mak said two or three students were evicted from hostels for breaking the rules every year. Another male student on the same floor as expelled exchange student Paul Naddaff was evicted after being caught playing mahjong with two male friends in his room during random checks on February 7. Mr Leung said they would arrange a discussion on the issue if enough students were interested. A spokeswoman for Hong Kong University said only some dormitory halls had restrictions on the visiting hours of hallmates of the opposite sex. Enforcement action was taken by monitors, who were all students, when they received complaints. A spokesman for the University of Science and Technology said while they had rules to restrict the visiting hours for non-hostel residents, they would only take enforcement action when they received complaints.
