The University of Hong Kong's governing council may examine members' email and phone messages as part of a "highly intrusive" investigation into leaks of confidential discussions. According to a source familiar with council matters, members at a meeting on Tuesday discussed a report compiled by a security consultant invited in January to make suggestions on improving the protection of council proceedings. "The consultant itself actually said it wouldn't recommend such a probe, citing privacy concerns," the source said. "But some council members are keen to investigate and no one expressed objections." If it goes ahead, a private firm will be hired to interview all council members and check their emails and records of mobile phone messages. A university spokesman said the council was "highly concerned about a series of leaks and will deal with them seriously". "The council will continue to investigate but will further consult experts before making a decision on how the probe should be conducted," the spokesman said. According to the source, the inquiry would not just look at disclosures to the press of recent discussions about whether to appoint liberal Professor Johannes Chan Man-mun to a top managerial post. It would also look at earlier revelations targeting Occupy Central co-founder Benny Tai Yiu-ting over his handling of donations. In December last year, Chinese-language newspaper Sing Tao Daily reported a council discussion about how to deal with the HKU law professor over his handling of donations to the university. Council member Dr Lo Chung-mau said he would not oppose the university's decision. "I don't have any special secrets," said Lo, adding that he had no concerns about privacy. "I think it's necessary to investigate or it will be very difficult [for the council] to do things." Council member Cheung Kie-chung also said he would have no objection. There are 22 council members. Four others - Man Cheuk-fei, Martin Liao Cheung-kong, Abraham Razack and Margaret Leung Ko May-yee - declined to comment. Lo, Cheung and Razack all denied being behind the audio leaks this week.
