Equal Protection Clause
The meaning of the Equal Protection Clause has been the subject of much debate. It has inspired the well-known phrase "Equal Justice Under Law".  These words are inscribed on the U.S. Supreme court building. This clause was the basis for Brown v. Board of Education (1954). This Supreme Court decision that helped to dismantle racial segregation, and also the basis for many other decisions rejecting discrimination against people belonging to various groups.
