The number of Wisconsin counties issuing marriage licenses to gay and lesbian couples grew to 12 on Monday.

Hundreds of gay couples married over the weekend in Milwaukee and Madison after a federal judge on Friday declared invalid Wisconsin's 2006 voter-approved constitutional amendment prohibiting state officials from recognizing any union other than a heterosexual marriage.

Most of the state's 72 counties were still turning away gay couples on Monday, but the list of counties issuing marriage licenses to gay couples grew to 12, including Milwaukee County, Waukesha County, Kenosha County, Dane County, Rock County, Dodge County, Outagamie County, Brown County, Green County, Jackson County, Door County and Appleton County.

Officials in Eau Claire County said they have yet to make a final decision on the matter.

Unlike clerks in Milwaukee and Madison, Outagamie County Clerk Lori O'Bright said she would not waive the state's five-day waiting period.

In handing down her ruling, U.S. District Judge Barbara Crabb declared the state's restrictive marriage ban unconstitutional but also gave the ACLU, which is representing the 8 plaintiff couples in their challenge, until June 16 to tell her what parts of the law it wants her to block.

Crabb has scheduled a 1 PM hearing on an emergency motion to stay the ruling filed by Attorney General J.B. Van Hollen. Hollen, a Republican, also turned to the 7th U.S. Circuit Court of Appeals, filing an appeal to the ruling and asking it for a stay.

“The State's interest in enforcing its own laws and in ensuring administrative clarity, as well as individual interests in certainty regarding marriage, demonstrate the irreparable injury that is likely to occur in the absence of a stay,” the state said in its filing.
