Wisconsin Supreme Court Statistics, 2019-20

These tables are derived from information contained in 45 Wisconsin Supreme Court decisions filed between September 1, 2019, and the end of the court’s term in the summer of 2020.  The total of 45 decisions omits orders pertaining to various motions, petitions, and disciplinary matters, but it does include Service Employees International Union (SEIU), Local 1 v. Robin Vos and Nancy Bartlett v. Tony Evers.  Given that these two decisions contain some odd features (to be discussed in a subsequent post), they will figure in only some of the following tables (as indicated by footnotes).

Waukesha County v. J.J.H. and State v. Kelly James Kloss were dismissed as improvidently granted and are not considered here.

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