Appellate Practice:

During the course of his career Mike has had the opportunity to argue many cases before the Wisconsin Court of Appeals and the Wisconsin Supreme Court. Mike’s efforts in those cases often clarified the law in Wisconsin and some of the cases he handled were responsible for changing the law entirely. Early on in Mike’s career, he represented a young man who was seriously injured while riding a motorcycle when a motorist turned in front of him. The motorist at-fault for the accident was uninsured. Mike’s client had no insurance on the motorcycle he was riding but he did have uninsured motorist insurance on a different vehicle he owned. On behalf of his client, Mike started an action against the insurance carrier and the insurance company argued that there was no coverage because of an exclusion in its insurance policy, which stated that there was no coverage if the injury occurred by an insured who was occupying his own vehicle that was not insured under the policy. Mike argued that this exclusion was contrary to the uninsured motorist statute and that it also violated public policy. He argued to the Wisconsin Supreme Court that that uninsured motorist coverage should follow the person and not just the vehicle. This case changed the law in the State of Wisconsin so that uninsured motorist coverage now follows the person rather than the vehicle, allowing for much broader coverage. Bauer v. Securities Mutual Ins. Co., 99 Wis. 2d 332, 298 N.W. 2d 58 (1980).

Another case Mike worked on that got state wide attention involved the Wisconsin Dog Bite statute and the liability of a harborer of a dog as opposed to a dog owner. Mike’s client was on her daily walk in her neighborhood when a person opened a house door and two large dogs came charging at her, knocking her down and attacking her. The owner of the dogs was the one that opened the door and let them out. He was residing with a friend and had been for a couple of months. The dogs’ owner had no home owners insurance and disappeared by the time Mike got the case. Mike sued the homeowner who had allowed the dogs’ owner and the dogs to stay at her house. Mike argued that the homeowner was a “harborer” under the statute and as such, a “statutory owner,” making her own homeowner’s policy liable for the loss. The trial court disagreed with Mike and denied his claim but the Wisconsin Court of Appeals and the Wisconsin Supreme Court disagreed, holding in favor of Mike and his client.

“The purpose of the statute is to protect from harm the surrounding neighbors, passers-by and those who come in proximity to a dog. If a neighbor agrees to keep and shelter a dog in the home, it means the dog is living in that home just as much as would be the case if the homeowner was the legal owner of the dog. Unless and until the homeowner's status as keeper is intentionally terminated in time and space by the dog's removal from the home, that homeowner is strictly liable for any dog-bite injury to his or her neighbors, passers-by and others in proximity. I do not believe the legislature meant to allow the keeper of the dog to avoid strict liability to his or her neighbors, passers-by or others in proximity by pointing a finger at someone else and arguing that at that certain moment in time, even though the dog was still within the perimeter of the homeowner's property, he or she had temporarily stopped being the keeper. To allow such a result would be to drown the statute in a sea of minutiae.” (Pawlowski, 2009 WI 105 at ¶ 77).
