Wisconsin Supreme Court Statistics, 2020-21

These tables are derived from information contained in 51 Wisconsin Supreme Court decisions filed between September 1, 2020, and the end of the court’s term in the summer of 2021.  The total of 51 decisions omits orders pertaining to various motions, petitions, and disciplinary matters involving lawyers and judges. 

Also excluded are (1) Portage County v. E. R. R., which yielded a deadlocked (3-3) per curiam decision, (2) Fond du Lac County v. S.N.W., which was dismissed as improvidently granted, and (3) Original Action petitions which were denied. 

Two cases, both titled Clean Wisconsin, Inc. v. DNR, resulted in separate decisions, each of which is counted here.

Three cases (Sara Lindsey James v. Janel Heinrich; WCRIS v. Janel Heinrich; and St. Ambrose Academy, Inc. v. Joseph T. Parisi) were consolidated and resolved with a single decision—hence they are counted as one case.

The tables are available as a complete set and by individual topic according to the subsets listed below.
