Citing U.S. ruling, gay-marriage advocates ask court to swiftly end Illinois ban

Motion says same-sex couples in state are being denied newly approved federal benefits.

Plaintiffs in an Illinois lawsuit seeking to strike down the state’s ban on same-sex marriage have filed a motion for summary judgment, citing a recent U.S. Supreme Court ruling that gives same-sex couples federal marriage benefits.

The American Civil Liberties Union of Illinois and the gay rights group Lambda Legal filed the motion Wednesday in Cook County Circuit Court arguing that same-sex couples in the state are now unable to access the federal benefits available to gay and lesbian couples in states where same-sex marriage is legal.

Last month, the high court struck down part of the Defense of Marriage Act, which had barred the federal government from recognizing same-sex marriages.
