Wis. Stat. § 196.64
A treble damage claim is no longer a separate cause of action because gross negligence is to be compared like all other negligence. Kania v. Chicago & North Western Railway Co. 57 Wis. 2d 761, 204 N.W.2d 681 (1973). An award of treble damages does not require proof of willful, wanton, or reckless behavior. This provision is constitutional. Peissig v. Wisconsin Gas. Co. 155 Wis. 2d 686, 456 N.W.2d 348 (1990). Principles of subrogation law prevent insurers from recovering treble damages. Beacon Bowl v. Wisconsin Electric Power Co. 176 Wis. 2d 740, 501 N.W.2d 788 (1993). This section does not establish a cause of action separate from one sounding in negligence and does not apply to contract actions. Recycle Worlds Consulting Corp. v. Wisconsin Bell, 224 Wis. 2d 586, 592 N.W.2d 637 (Ct. App. 1999), 98-0752.
