On February 24, 1976, the Republic of Cuba promulgated the Socialist Constitution of Cuba. The document solidified the socialist system in Cuba. It was the fifth Cuban constitution since the country's independence in 1901 and the first since the Cuban Revolution in 1959. The Socialist Constitution was subsequently amended in 1992 and 2002.

On February 24, 1803, Chief Justice John Marshall of the US Supreme Court ruled in Marbury v. Madison that any act of Congress that conflicts with the Constitution is null and void, thereby establishing the doctrine of judicial review.
