A Cook County judge won't decide until late September on whether to dismiss a lawsuit challenging the state's same sex marriage ban.
Circuit Judge Sophia Hall listened to nearly two hours of arguments on Tuesday. She then said she'll rule on Sept. 27. The lawsuit involves 25 couples who filed for marriage licenses in Cook County and were denied.
However, Cook County State's Attorney Anita Alvarez has refused to defend the state's ban, which defines marriage as between a man and a woman. She says it violates the state constitution.
Clerks from downstate were allowed to intervene and defend the ban.
Illinois approved civil unions in 2011, but attempts to legalize gay marriage have stalled.
