The first bill President Obama ever signed as President was the Lilly Ledbetter Equal Pay Act. The law amended the Civil Rights Act of 1964. It clarified the statute of limitations on bringing a claim of wage discrimination. Before the passing of the law and according to a 2007 Supreme Court case, the statute of limitations began when the wage discrimination began (presumably when a woman started her job). This meant that by the time a woman learned of the wage disparity, the statute of limitations may have already been fulfilled.
