OMAHA - A civil liberties group said Tuesday that five Nebraska counties accused of discriminating against immigrants seeking marriage licenses have changed or are working to change policies.

The Nebraska chapter of the American Civil Liberties Union had threatened in April to sue Hall, Lincoln, Dawson, Platte and Phelps counties after investigating reports they were illegally turning away Spanish speakers wanting to marry. But Tuesday, a representative of the group said she considers the case closed.

"I think this is part of the best thing about Nebraska," ACLU Nebraska legal director Amy Miller told The Associated Press. "The county clerks investigated promptly, changed their policies, retrained employees and have very enthusiastically assured the ACLU that there is no intent to discriminate against new immigrants."

Under state law, applicants for marriage licenses must show identification verifying their name and date of birth. Miller had said some counties were requiring other things, such as a Social Security number, a U.S.-issued photo identification card or a birth certificate translated into English.

In some cases, she said, even applicants who provided the additional documentation were turned away.

As part of its investigation, the ACLU had sent Spanish-speaking volunteers to each of the five counties to apply for marriage licenses.

The ACLU had threatened lawsuits if changes weren't made. Follow-up letters went out to Lincoln, Phelps and Platte counties about a month ago, giving them until the end of June to comply.

As of Tuesday, four of the counties had changed their marriage license requirements to only ask for what state law requires, Miller said. A fifth - western Nebraska's Lincoln County - asked for a few more days to make changes. County officials there only have to change a handout that Miller said implies marriage license applicants need a social security number. She said she was confident they would cooperate.

She said the group will contact other Nebraska counties in coming weeks to ensure they understand the law. Miller said the group also will continue to monitor the five counties over the next year, including sending in volunteers seeking licenses, but that she considered the situation a "happy ending."
