The U.S. District Court for the District of Maryland has tossed a motion to dismiss claims of fraud and civil rights violations against Walden University in a class action alleging the school misled students about the length of its doctorate program and its cost, overcharging enrolled members by more than $28.5 million.

Walden University, a Florida company, holds its academic headquarters in Minneapolis, while its principal place of business is in Baltimore. In 2008, the school offered its Doctor of Business Administration (DBA) program and advertised that it required 60 credits and cost between $43,000 and $63,000.
