DeStefano (2009) </Td> </Tr> <P> The Civil Rights Act of 1964 (Pub. L. 88--352, 78 Stat. 241, enacted July 2, 1964) is a landmark civil rights and US labor law in the United States that outlaws discrimination based on race, color, religion, sex or national origin . It prohibited unequal application of voter registration requirements, racial segregation in schools, employment, and public accommodations . </P> <P> Powers given to enforce the act were initially weak, but were supplemented during later years . Congress asserted its authority to legislate under several different parts of the United States Constitution, principally its power to regulate interstate commerce under Article One (section 8), its duty to guarantee all citizens equal protection of the laws under the Fourteenth Amendment and its duty to protect voting rights under the Fifteenth Amendment . The Act was signed into law by President Lyndon B. Johnson on July 2, 1964, at the White House . </P> <P> The bill was called for by President John F. Kennedy in his Report to the American People on Civil Rights of June 11, 1963, in which he asked for legislation "giving all Americans the right to be served in facilities which are open to the public--hotels, restaurants, theaters, retail stores, and similar establishments", as well as "greater protection for the right to vote". Kennedy delivered this speech following the immediate aftermath of the Birmingham campaign and the growing number of demonstrations and protests throughout the southern United States . Kennedy was moved to action following the elevated racial tensions and wave of black riots in the spring 1963 . </P>
