 Following her election, the Wisconsin Supreme Court, in a 5 to 1 decision, took the unprecedented step of publicly reprimanding Justice Ziegler for willful violations of the code of judicial conduct, stemming from her presiding over those cases where she had an apparent conflict of interest.Ziegler's contentious election campaign and subsequent reprimand began an era of acrimony and politicization of the Wisconsin Supreme Court.In 2015, Ziegler joined the 4 person majority which ended the John Doe investigation into possibly illegal coordination between the 2010 gubernatorial campaign of Scott Walker and business lobbying associations Wisconsin Manufacturers & Commerce and Wisconsin Club for Growth.
