The American Civil Liberties Union, the ACLU of Wisconsin, and the law firm of Mayer Brown have filed suit on behalf of four same-sex couples who were legally married in Wisconsin after a federal court struck down a state ban on marriage for same-sex couples, but before the judge temporarily halted marriages from taking place while the state challenged the decision. Although the marriages were valid, the state has announced that it has placed recognition of their marriages on hold indefinitely.
