In this personal injury case, Brian Bruttig, an adolescent minor, was injured while playing on a snowmobile with two other boys, Tim Louis and Douglas Olsen. Brian sued Tim and also sued Douglas' parents, David and Rita Olsen. After trial to a jury, Brian was found more negligent than any other individual. On appeal, he argues that the trial court wrongly refused to impute to each Olsen parent the negligence of the other, and wrongly denied his motion after verdict to charge each minor participant with an equal percentage of causal negligence. We reject his contentions and affirm.
On the day of Brian's injury, he, Tim and Douglas were playing "snowmobile tag" with the Olsens' snowmobile. The rules of the game require a driver and a passenger to drive the snowmobile through the Olsen yard and neighboring property while a third person tries to knock the passenger off of the vehicle. On this occasion, Tim was driving and Brian was the passenger, when Brian's leg became entangled in the snowmobile track.
Testimony at trial suggested different versions qf how the accident occurred. Under one version, Douglas pushed Brian, who then slid off the machine; under another, Brian let go of the safety strap and was dislodged from the machine while Douglas was some feet away; under a third, Brian was injured after he slid off the seat and tried to haul himself back up by the safety strap.
*274 At the time of the accident, David Olsen was separated from his wife Rita, although their divorce was not final. David visited on a weekly basis. He testified that he felt he had a responsibility and an opportunity to supervise Douglas. Rita, however, had physical custody of the boy.
At the close of testimony, the trial court proposed to submit a special verdict to the jury in which the negligence of Tim, Douglas, Brian, David and Rita would be separately determined. Brian objected, arguing that David and Rita's responsibility should be determined jointly. His argument was rejected. The court then instructed the jury on, among other things, the parental duty to control children and the duty of persons not to allow improper parties to use things or instrumentalities. The jury found all parties causally negligent and apportioned that negligence as follows:
a. David Olsen: 19%
b. Rita Olsen: 26%
c. Tim Louis: 4%
d. Douglas Olsen: 9%
e. Brian Bruttig: 42%
By motions after verdict, Brian renewed his request that the trial court impute the negligence of each Olsen parent to the other. He also requested that the negligence of the boys be combined and divided by three. The motions were denied. Further facts are set forth in the opinion as required.
In support of his argument that the negligence of David and Rita should be combined, Brian relies on
Reber v. Hanson,
The duty to protect inures to both parents and neither is excused from observing it whenever it is within their power to do so.
Id.
at 636,
In
Reber,
the court found that under the facts of that case, performance of the duty to protect lay within the power of both parents equally. The Reber child was fatally injured while playing in his parents' driveway. The
Reber
court held that the circumstances of that case were such that there was a present danger known to both parents.
Id.
at 637,
The
Reber
case is a lone exception to the general rule that the negligence of the parties is to be compared individually for purposes of determining whether liability exists.
Reiter v. Dyken,
Two duties are implicated here: the duty of a parent to control the conduct of a child and the duty not to permit a third person to use a thing or to engage in an activity which is under the control of the actor. These duties are set forth in
Bankert v. Threshermen's Mut. Ins. Co.,
Permitting Improper Persons to Use Things or Engage in Activities
It is negligence to permit a third person to use a thing or to engage in an activity which is under the control of the actor, if the actor knows or should know that such person intends or is likely to use the thing or to conduct himself in the activity in such a manner as to create an unreasonable risk of harm to others.
Duty of Parent to Control Conduct of Child
A parent is under a duty to exercise reasonable care so to control his minor child as to prevent if from intentionally harming others or from so conducting itself as to create an unreasonable risk of bodily harm to them, if the parent
(a) knows or has reason to know that he has the ability to control his child, and
*277 (b) knows or should know of the necessity and opportunity for exercising such control.
Thus, whether David and Rita are guilty of these torts turns on each one's knowledge of or opportunity to know about the conduct of the child.
David was not present at the home, or even living there, when the accident occurred, and in fact had been living away from home for six months previously. However, the game of snowmobile tag was of recent origin, and young Olsen deliberately hid its invention from his parents. Thus, unlike the
Reber
case, the fact finder could reasonably infer that David had no knowledge of the danger and was not able — or was at least less able than Rita — to discover it and exercise authority to stop it. Further, David had instructed his son to use the snowmobile only under certain conditions, specifically, neighbor boys could use it only when David was present and the boys were to use it responsibly. A party need not anticipate disobedience unless given a reason to do so.
Seibert v. Morris,
Rita, on the other hand, lived with the boys. Although she was away from home at the time of the accident, her daily proximity to the boys and the snowmobile could be found to give her greater opportunity than had David to observe any uses or abuses of the machine and to exercise discipline accordingly. The game was evidently invented and played while she alone had physical custody of her son. A jury could reasonably infer for her an opportunity greater than David's to con
*278
trol and a greater opportunity to know that the snowmobile was being used in an unreasonable way. Thus, even if the duties of the Olsen parents were considered equal, the opportunity to exercise them was not necessarily equal and the matter was properly before the jury.
See Mariuzza v. Kenower,
Additionally, we think public policy considerations underlying the
Reber
decision are not present here. Specifically, in
Reber,
husband and wife sued for damages. Realistically, where the marriage is intact, recovery to one spouse generally benefits both.
See Stull v. Ragsdale,
We turn, then, to Brian's second claim of error. He argues that the jury's apportionment of negligence was wrong and that as a matter of law the negligence of the three boys was equal. The argument is really twofold: first, Brian argues that the negligence of each boy was of precisely the same kind and character and therefore equal as a matter of law; second, Brian argues that the three boys acted in concert to commit a tortious act and therefore each boy should be charged with the causal negligence of the other and their percentages of negligence found equal. We disagree.
As to the first argument, apportionment is generally for the jury, although the trial court may on rare occasion find negligence to be equal where the negligence of each actor is of exactly the same nature and kind.
See Langworthy v. Reisinger,
In any event, it cannot be said that the negligence of each boy is of the same kind and character as a matter of law. For example, any negligence of Tim in operating the snowmobile improperly is necessarily of a different kind than is any negligence of Brian as passenger in failing to hold on.
Relying on
Ogle v. Avina,
Although couched in terms of apportionment, Brian's argument is in fact a separate theory of liability, that of "concerted action."
See Collins v. Eli Lilly Co.,
Wisconsin has never explicitly adopted the concerted action theory except in a variant form to impose joint and several liability on all defendants participating
*281
in a drag race.
Collins,
A litigant seeking to prevent a jury from apportioning liability among parties must raise the issue before it is submitted to the jury on a theory that the parties are to be compared individually.
Reiter,
By the Court — Judgment affirmed.
