Waseda University acted illegally by sending police a list of people who applied to attend a lecture by former Chinese President Jiang Zemin, saying it violated the applicants' privacy by disclosing personal information without their consent, the Supreme Court has ruled.

The decision, made Friday, has finalized a high court ruling that ordered the university to pay a total of 60,000 yen in compensation to six former students, while it sent another case, in which three former students had their plea for compensation rejected, back to the Tokyo High Court.

According to the previous rulings, Waseda passed the list of about 1,400 applicants to the November 1998 lecture to the Tokyo Metropolitan Police.
