Wisconsin Supreme Court Justice Annette Ziegler announced Monday that she will not run for a third term in 2027, setting up another open race for the seat. 

Ziegler, 62, plans to serve out the rest of her term but won’t run in the April 2027 race.

“After three decades on the bench, now is the right time for me to step away to spend more time with my husband, kids and grandkids,” Ziegler said in a statement. “I will, therefore, not be seeking reelection to the Wisconsin Supreme Court in 2027.” 

Ziegler was first elected to the Court in 2007. Ziegler won a second term in 2017 in an unusual race where there was no opposition, becoming the only justice to not draw an opponent over the past two decades.

“It has been the honor of my lifetime to serve as judge and justice for the past 30 years,” Ziegler said. “I will be forever grateful to the voters who elected me twice in Washington County and then twice to serve on our state’s highest court.”

Ziegler’s announcement comes about a month ahead of this year’s state Supreme Court race, which is open following the decision of her fellow conservative colleague, Justice Rebecca Bradley, to not seek reelection this year. 

Appeals court judge and former Democratic state Assembly member Chris Taylor and Appeals Court Judge Maria Lazar, a conservative, will face each other next month for that seat. 

The retirements of the two conservative justices comes after liberals won the majority on the Court in 2023 and held it in last year’s race.

Recent Supreme Court elections in Wisconsin have brought national attention and record spending for the nominally nonpartisan seats with the ideological balance of the Court at stake. The 2026  Supreme Court race has not received as much attention or spending with the liberal majority assured regardless of the outcome.  A victory for Taylor next month would increase the number of liberal justices on the Court, locking in a  5-2 liberal majority until 2030.

When Ziegler’s seat is up in 2027, liberals will likely look to extend their majority while conservatives will be looking to claw back some ground. 

“While I will not be a candidate next year, my appreciation for the people of Wisconsin and the judicial system I have been privileged to serve in remains as strong as ever,” Ziegler said. “I look forward to finishing out the rest of my term on the Court and handing the baton to a new justice in 2027.”

Ziegler served as the chief justice from 2021 to 2025. She was the second justice to be elected to the position after a 2015 constitutional amendment made it an elected position rather than one selected based on seniority. 

When the Court flipped to a liberal majority in 2023 for the first time in 15 years, the liberal members voted to weaken the powers of the chief justice, putting some of the powers under the control of a three-member administrative committee and making a series of changes to the Court’s internal operating procedures. Ziegler at the time called the move an overreach by “rogue justices.”

Ziegler worked as a private lawyer, an assistant U.S attorney and as Washington County Circuit Court judge, a position to which she was appointed by Republican Gov. Tommy Thompson, before she was elected to the Supreme Court. Ziegler earned her law degree from Marquette University.
