Northern Michigan University has confirmed that the United States Justice Department is investigating a civil rights complaint filed against the school. At issue is a university policy that prohibited students from discussing some mental health issues, including thoughts of suicide, with other students. That policy has since been changed. An unidentified student who says they were threatened with expulsion from the university registered the complaint through the Michigan Protection and Advocacy Service. In a statement, the University says state laws protecting student privacy prevent its officials from discussing the specifics of the case. The school has pledged to cooperate with the investigation.
