Equal Pay Act of 1963
In 1942, Republican congresswoman Winifred C. Stanley from Buffalo, N.Y. introduced H.R. 5056, Prohibiting Discrimination in Pay on Account of Sex, which did not pass at the time. The issue languished until 10 June 1963, when Congress passed the Equal Pay Act ("EPA" or the "Act") as an amendment to the Fair Labor Standards Act, to "prohibit discrimination on account of sex in the payment of wages by employers."
Lilly Ledbetter Fair Pay Act of 2009
An earlier bill seeking to supersede the "Ledbetter" decision, also called the Lilly Ledbetter Fair Pay Act, was first introduced in the 110th United States Congress but was not successfully enacted at that time, as it was passed by the House but failed in the Senate.
