Wisconsin Supreme Court

Just like the United States Supreme Court, state supreme courts rule on many different types of issues affecting people’s daily lives. From decisions affecting corporate accountability and consumer protection; employment protections and workers’ rights; voting rights and redistricting matters; student debt relief and issues affecting young people; access to affordable healthcare; climate change and environmental protections; a variety of issues that directly impact people’s lives are decided by state supreme courts. Many people do not realize what a critical role the justices seated on these supreme courts play on issues that matter to them.

In recent years, the Wisconsin Supreme Court has been positioned to issue the final ruling on a number of cases, including public health, democracy, collective bargaining, and criminal justice. There have been several important cases affecting democracy and voting rights in Wisconsin. The Supreme Court issued a ruling in Richard Teigen v. Wisconsin Elections Commission only few weeks before the 2022 primary election, deciding that state election law requires ballot drop boxes to be staffed. This forced the state’s Department of Elections to close 570 unstaffed, or absentee, ballot drop boxes, leaving only drop boxes inside clerks’ offices, accessible only during regular business hours. This ruling went against advice from the state’s Department of Elections, rolling back voting protections that had been instituted in the state in the wake of the COVID-19 pandemic. Also in 2022, the Supreme Court ruled in Johnson v. Wisconsin Election Commission to implement a set of legislative redistricting maps that had been drawn by legislators after they had been vetoed by Governor Tony Evers. In late 2020, Wisconsin was one of several states where former President Donald Trump challenged the results of the 2020 presidential election. Trump’s lawyers argued that massive fraud had occurred in the state’s voting system and asked the court to throw out 200,000 votes, disenfranchise voters, and award the state’s electoral votes to Trump. The Supreme Court rejected Former President Donald Trump’s argument and upheld Joe Biden’s victory in the state. With this ruling, the Wisconsin Supreme Court played crucial role in upholding the results of the 2020 election, protecting democracy and the rule of law.

The State Court has an important duty to protect the public health and safety. In Becker v. Dane County, the court ruled to limit Governor Evers’ authority to issue public health orders and to give power to issue public health orders to local health departments instead. This decision came after a 2020 ruling that overturned Governor Evers’s stay-at-home order, issued in the first weeks of the pandemic and challenged by legislators in Wisconsin Legislature v. Palm, et al..

The Wisconsin Supreme Court has ruled in recent years to limit the authority of the state’s gubernatorial office. In 2015, the Supreme Court ruled in Three Unnamed Petitioners v. Gregory A. Peterson to halt an investigation into whether Republican Governor Scott Walker’s 2012 recall campaign had illegally coordinated with conservative interest groups. The court found that the investigation’s special prosecutor had acted unconstitutionally and ordered evidence gathered during the investigation to be returned or destroyed. Later that same year, the state’s highest court clarified and reaffirmed its decision from earlier that year that the John Doe investigations of Governor Walker’s recall campaign were unconstitutional.

The WI Supreme Court must also protect workers and consumers. In 2011, the Wisconsin Supreme Court ordered the reinstatement of Act 10, Governor Walker’s signature legislation that stripped collective bargaining rights from the state’s public employees, despite months of vocal public protests and numerous lawsuits filed by the unions who represented these workers.

These rulings make clear that the Wisconsin Supreme Court plays an important role in the lives of people across Wisconsin. In all these cases and potential outcomes, it is critical for the Wisconsin Supreme Court to rule in a way that will protect and defend the rights of all Wisconsinites.

The seven justices of the Wisconsin Supreme Court are elected in statewide nonpartisan elections on the first Tuesday in April to serve ten-year terms. To remain on the court, justices must run for re-election after the expiration of their term. Only one seat may be elected in any year. If more than two candidates file for each seat, a primary must be held on the third Tuesday in February.

Under the Wisconsin Constitution, to qualify for a judgeship in Wisconsin a person must be under the age of 70 and must be licensed to practice law in Wisconsin for a minimum of five years prior to their election or appointment. The state previously had a mandatory retirement age of 70 for all judges and justices. In 1977, the state’s constitution was amended to authorize the legislature to impose a maximum age of no less than 70. The legislature has since introduced several bills to impose a mandatory retirement age, but none have become law.

Until 2015, the justice with the longest continuous service on the court served as the chief justice. An amendment to the state constitution passed in 2015 eliminated the seniority selection of the chief justice and replaced it with a two-year term as chief justice via peer vote of the current justices.

If a vacancy occurs on the court, the governor has the power to appoint someone to fill the vacancy. The governor may choose an advisory committee to recommend candidates but is not bound by its recommendations. The person appointed to fill the vacancy must then run for election in the first year after their appointment in which no other justice’s term expires.
