<human>:  Can you tell me how gay marriage laws have changed in the US in recent years?
<bot>: Sure. Currently in the United States, the Supreme Court ruled on June 26, 2015 that gay couples are permitted to marry in all states. There was a debate at the time about whether this ruling was a change in policy or not, and whether the Court is in fact still bound by the precedent of Romer v. Evans, which held that the right to gay marriage had no basis in the Constitution and therefore could not be “construed” into existence. The position of many legal scholars was that the ruling in Obergefell v. Hodges effectively overturned the Court’s decision in Romer.
