The court, led by Justices Ruth Bader Ginsburg, Anthony Kennedy, Sonia Sotomayor, Stephen Breyer, and Justice Elena Kagan said that states must grant marriage licenses to same sex couples. Until today, several states that border Iowa had bans on same sex marriage, including Nebraska, North Dakota, South Dakota and Missouri. Iowa and Minnesota already allow same sex couples to marry.
In the ruling, the court declared that the Fourteenth Amendment requires a state to license a marriage between two people of the same sex and to recognize a marriage between two people of the same sex when their marriage was lawfully licensed and performed out-of-state.
