The case for gay marriage got a big boost last summer.
In late June, the Supreme Court struck down part of the Defense of Marriage Act, granting legally married same-sex couples full federal recognition. Since then, in ruling after ruling, federal judges have invoked that decision — United States v. Windsor — in siding against state same-sex marriage bans.
Some decisions were incremental, granting gay couples partial or temporary rights on the grounds that a given state’s ban is likely to be overturned. Others were much more direct: same-sex marriage bans were found to be unconstitutional. In all, the judicial thinking behind the Windsor decision played a key role.
Here’s a look at the 13 federal court decisions that have, in some significant way, ruled against state same-sex marriage bans since then.
(Note: This list is limited to federal rulings. Some have gone into effect, allowing gay couples to marry even as states defend bans; others have been put on hold until the case is resolved, possibly by the Supreme Court.)
