Wisconsin Supreme Court

• ↑: Subsequently elected in her own right.

In 2009, the United States Supreme Court decided Caperton v. A.T. Massey Coal Co., holding 5-4 that a campaign expenditure of over $3 million by a corporate litigant to influence the election of a judge to the court that would hear its case, although legal, was an "extreme fact" that created a "probability of bias", thus requiring the judge to be recused from hearing the case.[3] Wisconsin had adopted a limit of $1,000 for campaign contributions to judges, but it was unclear when mandatory recusal was required.[4] The League of Women Voters petitioned the Court to require a judge to recuse himself or herself from a proceeding if the judge had received any campaign contributions from a party or entity involved in it.[4] Instead, during its 2009-2010 term and by a 4-3 vote, the Court adopted a rule that recusal is not required based solely on any endorsement or receipt of a lawful campaign contribution from a party or entity involved in the proceeding, and that a judge does not need to seek recusal where it would be based solely on a party in the case sponsoring an independent expenditure or issue advocacy communication in favor of the judge. Voting in favor of the new rule were Prosser, Gableman, Roggensack, and Ziegler. Voting against were Abrahamson, Crooks, and A. Bradley. In the opinion of Justice Roggensack, "when a judge is disqualified from participation, the votes of all who voted to elect that judge are cancelled for all issues presented by that case. Accordingly, recusal rules . . . must be narrowly tailored to meet a compelling state interest." In dissenting, Justice A. Bradley called the decision "a dramatic change to our judicial code of ethics" and took issue with the majority's decision to adopt a rule "proposed by special interest groups."[4]

On June 13, 2011, a confrontation between Justices David Prosser, Jr. and Ann Walsh Bradley occurred in Bradley's chambers. Prosser, Bradley, and the other justices (except N. Patrick Crooks) were discussing the following day's decision that would overturn a ruling blocking the Wisconsin collective bargaining law. Witnesses stated that the incident happened after Prosser had stated that he'd lost all confidence in the leadership of Chief Justice Shirley Abrahamson.[5] Bradley later accused Prosser of putting her in a chokehold.[5] Prosser denied the allegations and asked for "a proper review of the matter and the facts surrounding it".[5] The incident was investigated by the Dane County Sheriff's Office. Witnesses to the incident disagreed about what had happened[5] and neither Prosser nor Bradley was charged by a special prosecutor.[6] Ethics charges brought against Prosser based on Bradley's allegations were never adjudicated due to the lack of a quorum on the Court after recusals.[7]

Although elections to the Wisconsin Supreme Court are nonpartisan, campaigns for the seats sometimes generate partisan fervor. As a result, elections have become expensive; over $4.3 million was spent in the 2016 race.[8]

On April 6, 2020, amid the COVID-19 pandemic, the Wisconsin Supreme Court ruled, virtually due to the pandemic, that Governor Tony Evers could not delay the state's 2020 primary elections, despite public fears of COVID-19.[9]

On May 13, 2020, the court ruled 4-3 to strike down Governor Tony Evers' stay-at-home order after a lawsuit by the Republican-led state legislature. The portion of the order that kept all K-12 schools closed for the remainder of the school year remained in effect.[10] The deciding vote to strike down the stay-at-home order was by Daniel Kelly, who had recently lost his bid for re-election to Jill Karofsky.[11]

Michael Gableman did not seek re-election in 2018.[12] Two county judges, Rebecca Dallet and Michael Screenock, ran for the open seat.[13][14] A third candidate, Tim Burns, did not make it to the general election in the February 20 primary. Dallet was elected in the April 3 general election.[15]

Incumbent Justice Shirley Abrahamson, who had served on the court for 42 years, did not seek re-election in 2019. Appeals Judge Brian Hagedorn was elected to succeed her in the April 2 general election, and took his seat on the court on August 1, 2019.

On April 7, 2020, liberal Jill Karofsky defeated conservative incumbent Daniel Kelly as Justice of the Wisconsin Supreme Court. The election was controversially held during the coronavirus pandemic, forcing many voters to vote by mail, wait in long lines for hours, or not participate at all.[16]
