Wisconsin Referendum 1 of 2006 was a referendum on an amendment to the Wisconsin Constitution that would invalidate same-sex marriages or any substantially similar legal status.https://www.aclu-wi.org/en/news/timeline-freedom-marry-wisconsin Timeline for freedom to marry in Wisconsin October 9, 2014 ACLU June 14, 2025 https://web.archive.org/web/20210426044017/https://www.aclu-wi.org/en/news/timeline-freedom-marry-wisconsin April 26, 2021 The referendum was approved by 59% of voters during the general elections in November 2006. All counties in the state voted for the amendment except Dane County (home of the state capital, Madison, and the University of Wisconsin), which opposed it. The constitutional amendment created by Referendum 1 was invalidated by the United States Court of Appeals for the Seventh Circuit in Wolf v. Walker in 2014, and has been effectively nullified since June 26, 2015, when the United States Supreme Court ruled in Obergefell v. Hodges that state-level bans on same-sex marriage are unconstitutional.https://edition.cnn.com/videos/us/2015/06/26/supreme-court-same-sex-marriage-ruling-brown-dnt-tsr.cnn U.S. 21st country to allow same-sex marriage nationwide June 26, 2015 CNN

Effects
The amendment, which took effect on November 7, 2006, constitutionally banned same-sex marriages, which were never recognized by the state and was statutorily banned since 1979, and civil unions or civil union equivalents, which were never recognized by the state. Wisconsin became the 21st US state to ban same-sex marriage in its constitution and 14th US state to ban civil unions or civil union equivalents in its constitution. This preempted the state judiciary from requiring the state to legally recognize same-sex marriages or civil unions or civil union equivalents and preempted the Wisconsin Legislature from enacting a statute legalizing same-sex marriages or civil unions or civil union equivalents. Domestic partnerships in Wisconsin, legal statewide for state employees only and 1 county and 3 municipalities at the time, were unaffected by the amendment. In 2009, Wisconsin would enact statewide domestic partnerships for everyone, which would later be repealed in 2018.
Legal challenge
In April 2009 the Wisconsin Supreme Court was asked in McConkey v. Van Hollen to rule on whether the 2006 Referendum 1 was constitutional. William McConkey, a political science instructor, claimed that the measure violated the state's constitution because it proposed more than one question in a single ballot proposal, which is impermissible under Wisconsin law.Wisconsin amendment supreme courtChristopher Magnum, Wis.
