A former law student has filed a federal class action against St. Thomas University School of Law of Miami, claiming that it is illegally accepting and then expelling more than 25 percent of its first-year class to boost its flagging bar pass rates.

Filed in U.S. District Court for the District of New Jersey, the complaint alleges that the private law school unlawfully dismissed Thomas Joseph Bentey and as many as 80 students from the incoming class of 2005 because they failed to maintain a 2.5 grade point average.
