CHICAGO — With time running out on Illinois’s legislative session, State House members on Friday night chose not to call a vote on whether to permit same-sex couples to wed, apparently because supporters of same-sex marriage did not have enough votes to pass the measure in the Democratic-controlled House.

The outcome — which, at a minimum, delays the question for months — came as a grave disappointment to supporters, who had hoped to make Illinois the 13th state to permit same-sex marriage. The state has allowed civil unions for same-sex couples since 2011.

Critics of same-sex marriage said the outcome was a rejection of the entire notion, while supporters said a vote was merely delayed and could now come in the fall during a later session.

The State Senate approved the measure in February. Gov. Pat Quinn, a Democrat, had long urged House members to support the measure and promised that he intended to sign it. And during a fund-raising event in Chicago on Wednesday, President Obama mentioned the likelihood of a vote in Springfield, where he was a state senator, saying, “It’s something that I deeply support.”
