Wisconsin Supreme Court Statistics, 2017-2018

These tables are derived from information contained in 59 Wisconsin Supreme Court decisions filed between September 1, 2017, and the end of the court’s term in the summer of 2018.  The total of 59 decisions does not include (1) orders pertaining to various motions, petitions, and disciplinary matters, and (2) a case dismissed because review had been improvidently granted (Mark Halbman v. Mitchell J. Barrock).

In addition to the 59 decisions noted above, three deadlocked (3-3) per curiam decisions were filed (In Re: Partnership Health Plan, Inc. v. Office of the Commissioner of Insurance; Wingra Redi-Mix, Inc. v. Burial Sites Preservation Board; and Wingra Redi-Mix, Inc. v. State Historical Society of Wisconsin).  As we have not been informed how individual justices voted, these cases are included only in the “Number of Oral Arguments Presented” table. 

It is also worth noting that State v. David Hager, Jr. and State v. Howard Carter were consolidated after oral argument and handled in a single decision.  For our purposes, this is counted as one decision rather than two.

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