Three students are suing Mountain State University, former President Charles Polk and the Board of Trustees over the school's revoked accreditation, saying it renders their degrees worthless.

Dale Burger and his two children, Amanda and Jeff Burger, are seeking class-action status for their case, filed late Wednesday in Kanawha County Circuit Court.

Some 3,000 students were enrolled as of April, the lawsuit says. But the plaintiffs contend that the class should cover anyone who enrolled since July 10, 2008. That's when the school first learned it might be in trouble.

The lawsuit says Mountain State told students it was in sound shape when it knew otherwise.

A spokesman declined comment on the lawsuit Thursday.

The private Beckley-based school has campuses in West Virginia, Florida, North Carolina and Pennsylvania.

Mountain State is appealing the Higher Learning Commission's decision to withdraw general accreditation.
