A Manhattan federal judge has thrown out a race discrimination suit brought against DLA Piper by a former associate who claimed the firm’s New York office was a hostile work environment.

Charlene Morisseau, a 2001 graduate of Harvard Law School, where she was a law review editor, joined DLA Piper as a litigation associate in April 2003 but was asked to leave less than a year later. In a lawsuit filed last year, Morisseau, who is black, claimed her firing was retaliation for complaints she had made about discriminatory treatment.
