Wis. Stat. § 788.11
The intent of the parties controls a determination under sub. (1) (b) whether a matter was submitted to the arbitrator. Milwaukee Professional Fire Fighters Local 215 v. Milwaukee, 78 Wis. 2d 1, 253 N.W.2d 481 (1977). A court had no jurisdiction to vacate or modify an award if grounds under s. 788.10 or 788.11 did not exist. Milwaukee Police Association v. Milwaukee, 92 Wis. 2d 175, 285 N.W.2d 133 (1979). The arbitration panel's decision in this case was properly modified by the circuit court under ss. 788.10 and 788.11 because the arbitrators exceeded their authority by failing to fully review and apply the supreme court's decisions on the collateral source rule and the law of damages. Orlowski v. State Farm Mutual Automobile Insurance Company, 2012 WI 21, 339 Wis. 2d 1, 810 N.W.2d 775, 09-2848.
