Wisconsin Supreme Court Statistics, 2022-23

These tables are derived from information contained in 45 Wisconsin Supreme Court decisions filed between September 1, 2022, and the end of the court’s term in the summer of 2023.  The total of 45 decisions omits orders pertaining to various motions, petitions, and disciplinary matters involving lawyers and judges. 

Also excluded are (1) Neil J. Rennick v. Teleflex Medical Incorporated (a 3-3 per curiam decision); (2) Robert L. Slamka v. General Heating and Air Conditioning and State v. Daimon Von Jackson, Jr. (both dismissed as improvidently granted); and (3) Pepsi-Cola Metropolitan Bottling Company, Inc. v. Employers Insurance Company of Wausau (Justice Ziegler did not participate, and Justice Hagedorn withdrew from participation.  No trio of the remaining justices could agree on a ruling.)

When two cases were consolidated and decided with a single decision, they are counted as only one.

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