A federal jury took barely three hours yesterday to throw out claims from a former staff attorney with the First Department’s disciplinary committee that she had been fired in retaliation for the exercise of her First Amendment rights.

The unanimous, eight-member Southern District jury rejected the civil rights suit brought by Christine A. Anderson, who claimed she was fired in 2007 because she objected that officials at the committee were “whitewashing” complaints and giving preferential treatment to attorneys with connections.
