MADISON, Wis. (AP) — Gay couples across Wisconsin rushed to secure marriage licenses Monday, hoping to win legal recognition of their relationships ahead of an expected hold on a ruling that the state's same-sex marriage ban is unconstitutional.

U.S. District Judge Barbara Crabb in Madison struck down the ban Friday in an American Civil Liberties Union lawsuit challenging the prohibition. But she didn't order county clerks to begin issuing licenses or block them from handing them out. She said she wants the ACLU to draft an order for her spelling out how the organization wants her decision implemented.

Her stance has left county clerks to decide on their own whether they can legally issue licenses to same-sex couples. Clerks in Milwaukee and Madison, the state's liberal hubs, began issuing licenses to same-sex couples within hours of the ruling. Together the counties issued 238 licenses on Friday and Saturday. According to the ACLU, at least 20 of Wisconsin's 72 counties were issuing licenses as of Monday afternoon.

Dozens of couples were initially refused licenses in Appleton, Green Bay and elsewhere on Monday while county clerks in those communities sought advice from the Wisconsin Vital Records Office, which keeps marriage records. Nearly 100 people at the Outagamie County Clerk's office in Appleton objected when told they could not apply for licenses.

"We did tell them we weren't leaving until licenses were issued," said Kathy Flores, 47, of Appleton, who plans to seek a license to marry her partner, Ann Kendzierski.

Soon after, Outagamie County attorney Joe Guidote told couples that he had advised Clerk Lori O'Bright to accept applications for licenses. Flores said later that she knew one couple who received a waiver because a parent was very ill.

Brown County Clerk Sandy Juno said she decided to issue licenses to about 10 couples at her Green Bay office after failing to reach anyone in the Wisconsin Vital Records Office. She said she explained to couples the work would stop as soon as a court put the judge's decision on hold.

La Crosse County Clerk Ginny Dankmeyer said a county attorney told her not to issue licenses until after Crabb's June 16 deadline for the ACLU to submit its injunction. St. Croix County deputy clerk Cheryl Harmon said her office in Hudson had been told the same thing by its attorney and also was waiting.

Waukesha County Clerk Kathleen Novack said her office west of Milwaukee began accepting applications for licenses about 9:30 a.m. Monday after she talked to a county attorney, saw what other counties were doing and spoke with waiting couples. Her office had issued about a half-dozen licenses in the first half-hour and expected perhaps two dozen or so more by the end of the day.

The Rock County clerk's office in Janesville said it issued two licenses before noon on Monday. Kenosha County Clerk Mary T. Schuch-Krebs said she gave a license to one couple who told her they planned to marry that night.

"I don't see anything that tells me otherwise," she said.

How long the couples' window stays open is anyone's guess.

Republican Attorney General J.B. Van Hollen asked Crabb to issue an emergency stay barring clerks from issuing licenses while he appeals the constitutionality decision. He also petitioned the 7th Circuit Court of Appeals on Monday to halt the marriages.

"There is absolutely no reason to allow Wisconsin's county clerks to decide for themselves, on a county-by-county basis, who may and may not lawfully get married in this state," Van Hollen said in a statement.

Crabb issued an order Monday denying an emergency stay, saying clerks weren't issuing licenses because of anything she did. The judge said since she didn't issue an order it's not clear what Van Hollen wants to stop. Once both sides have a chance to weigh in on the scope of the ACLU's proposed order she'll decide whether to put it on hold, she said.

The 7th Circuit, meanwhile, could rule at any moment.

University of Richmond law professor Carl Tobias said Saturday he expected Van Hollen to receive a stay. He noted that more than 1,000 couples married in Utah before a stay was issued there, and a judge recently said those marriages were valid. That decision, like others related to gay marriage, has been appealed.

Given events around the nation, Tobias said he expects the U.S. Supreme Court to weigh in on the issue next year.

"I'm cautiously optimistic that everything will be fine for those couples," Tobias said, "but we just don't know right now."
