jan 1, 1976 - Craig v. Boren, 429 U.S. 190: The U.S. Supreme Court declares unconstitutional a state law permitting 18 to 20-year-old females to drink beer while denying the rights to men of the same age. The Court establishes a new set of standards for reviewing laws that treat men and women differently—an “intermediate” test stricter than the “reasonableness” test for constitutionality in sex discrimination cases
