Judge Strikes Down Wisconsin Gay Marriage Ban

A federal judge has struck down Wisconsin's ban on same-sex marriage, ruling it unconstitutional.

U.S. District Judge Barbara Crabb issued the ruling Friday, but it wasn't clear whether same-sex marriages could immediately begin. 

But the ruling makes Wisconsin the 27th state where same-sex couples can marry under law or where a judge has ruled they ought to be allowed to wed.

Clerks in the state's two largest cities of Milwaukee and Madison had been preparing for such a ruling by bringing in extra staff to handle an expected flood of marriage-license applicants.

The lawsuit was brought by the American Civil Liberties Union on behalf of eight same-sex couples. 

Gov. Scott Walker has been a strong proponent of the constitutional same-sex marriage ban that was approved by state voters in 2006.
