Wisconsin Supreme Court Statistics, 2018-19

These tables are derived from information contained in 58 Wisconsin Supreme Court decisions filed between September 1, 2018, and the end of the court’s term in the summer of 2019. The total of 58 decisions omits orders pertaining to various motions, petitions, and disciplinary matters, but it does include three deadlocked (3-3) per curiam decisions. As the court no longer indicates how each justice voted in these deadlocked cases, they are included only in the “Number of Oral Arguments Presented” table.

Normally, when two cases have been consolidated and resolved with a single decision (as in Enbridge Energy Company, Inc. v. Dane County), I record this as one case. However, with State v. Raytrell K. Fitzgerald and Raytrell K. Fitzgerald v. Circuit Court for Milwaukee Co., we have a more unusual situation. These two cases were consolidated and handled in a single decision—but, they were argued separately (that is, in two different oral-argument “slots” and consolidated thereafter) and decided by different votes (6-0 and 3-3). Thus, I have counted them as two separate cases in the tables that follow.

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

Four-to-Three Decisions
Decisions Arranged by Vote Split
Frequency of Justices in the Majority
Distribution of Opinion Authorship
