These cases are about whether states are required to license same-sex marriages or to recognize lawful same-sex marriages performed in other states. In 2013, the Supreme Court ruled that one part of the federal Defense of Marriage Act was unconstitutional under the Fifth Amendment and the federal government had to treat same-sex married couples the same as all other married couples. Does the Fourteenth Amendment require states to do the same? Moreover, does the Fourteenth Amendment require that all states permit marriages between two people of the same sex?
