Final answer:
The 72-Hour Rule does not refer to a specific Act but pertains to the general legislative procedure in passing bills. The Civil Rights Act of 1964, signed into law on July 2, 1964, was passed after overcoming significant opposition in the Senate and illustrates the broader legislative process.
Step-by-step explanation:
The Civil Rights Act of 1964 and the 72-Hour Rule
The 72-Hour Rule is actually not part of a specific act but is a general legislative procedure that is derived from the way the U.S. Congress passes bills. However, the process of how a bill becomes a law is relevant to the history of the Civil Rights Act of 1964, which President Lyndon B. Johnson signed into law. This landmark legislation came to fruition after President John F. Kennedy's proposal faced a Senate filibuster. After Kennedy’s assassination, President Johnson relentlessly advanced the Act through Congress, and it was finally enacted with significant bipartisan support, with a Senate vote of 73-27 and a House vote of 289-126. The Civil Rights Act was signed into law on July 2, 1964, at the White House.
The Act was later extended and updated to include protections for other groups, including Hispanics, Asians, and Native Americans, and renewed in 1982 and 2006. The legislative journey of the Civil Rights Act is an example of the broader process detailed in Section 7 Clause 2 of the U.S. Constitution on how a bill, once passed by both houses of Congress, must be signed by the President to become law or faced with veto options.
