The American Civil Liberties Union filed a friend-of-the-court brief opposing the legal challenge to overturn Wisconsin’s law granting limited domestic partnership protections to same-sex couples. The ACLU’s brief was filed on behalf of five couples who stand to lose crucial protections such as hospital visitation, the ability to make certain decisions about medical care and to access family medical leave if the law is overturned. The law is being challenged by an anti-LGBT organization that contends that the law grants same-sex couples a substantially similar status to marriage, which is barred by the Wisconsin Constitution. The same organization originally campaigned to secure the marriage amendment’s passage, claiming at the time that domestic partnerships would not be affected.
