In April 2009, the United States Supreme Court agreed to hear a suit over reverse discrimination brought by 18 white firefighters against the city. The suit involved the 2003 promotion test for the New Haven Fire Department. After the tests were scored, no black firefighters scored high enough to qualify for consideration for promotion, so the city announced that no one would be promoted. In the subsequent Ricci v.
