In this April 28, 2015, file photo, demonstrators stand in front of a rainbow flag of the Supreme Court in Washington, as the court was set to hear historic arguments in cases that could make same-sex marriage the law of the land. Gay and lesbian couples could face legal chaos if the Supreme Court rules against same-sex marriage in the next few weeks. Same-sex weddings could come to a halt in many states, depending on a confusing mix of lower-court decisions and the sometimes-contradictory views of state and local officials. Among the 36 states in which same-sex couples can now marry are 20 in which federal judges invoked the Constitution to strike down marriage bans.
