¶ 1. The estate of Jean E. Dorschner appeals from a summary judgment enforcing the antistacking clause contained in an uninsured *264 motorist policy owned by Dorsehner at the time of her death. The estate asserts that the policy is ambiguous and illusory because it has not fulfilled its promise of mandatory coverage. Because WlS. Stat. § 632.32(5)(f) (1999-2000) 1 explicitly authorizes the type of antis-tacking provision contained in the policy, we affirm the order of summary judgment.
¶ 2. Dorsehner died of injuries sustained in a two-car accident. Dorsehner was a passenger in a car owned and operated by a relative. The accident was caused primarily by Gordon J. Servis, who was driving while intoxicated in an uninsured motor vehicle. The car in which Dorsehner was riding was insured by Economy Preferred Insurance Company (Economy). The Economy car policy provided uninsured motorist (UM) coverage with $100,000 per person and $300,000 per accident limits of liability. As an occupant of the car, Dorsehner was insured for UM coverage. Economy paid Dorschner's estate the full $100,000 limits of its coverage. The estate then sought to collect the $50,000 limits contained in a UM policy issued by State Farm Mutual Automobile Insurance Company (State Farm) and owned by Dorsehner at the time of her death. On a motion for summary judgment, the trial court held that the antistacking clause contained in Dorschner's policy prevents the estate from stacking the State Farm coverage on top of the Economy coverage.
¶ 3. The court of appeals reviews summary judgment motions de novo.
Blazekovic v. City of Milwaukee,
¶ 4. The source of contention between the parties is the following provisions contained in Endorsement 6083BB of Dorschner's policy, commonly known as the antistacking clause and the excess clause:
Regardless of the number of policies involved, vehicles involved, persons covered, claims made, vehicles insured, or premiums paid, the limits for uninsured motor vehicle coverage under this policy may not be added to the limits for similar coverage applying to other motor vehicles to determine the limits of uninsured motor vehicle coverage available for bodily injury suffered by an insured in any one accident.
Subject to the above:
2. If the insured sustains bodily injury while occupying a vehicle not owned or leased by you, your *266 spouse or your relative who resides primarily in your household, then this coverage applies:
a. as excess to any uninsured motor vehicle coverage which applies to the vehicle or driver as primary coverage; but
b. only in the amount by which it exceeds the primary coverage.
¶ 5. We understand the estate to argue that the excess clause has the effect of eliminating the policy's UM coverage altogether. 2 The purpose of mandatory UM coverage is to place the insured in the same position as if the uninsured motorist had been insured. Yet, according to the estate, the language of the policy's excess clause, which states that its coverage is applicable only in the amount by which it exceeds the primary coverage, circumvents this purpose. The estate contends that, in this case, the excess clause allows State Farm to pay nothing at all even though the decedent had paid for mandatory coverage: "To allow a policy to not provide any uninsured motorist benefits is contrary to public policy, Wisconsin Statutes and case law. [The estate] should receive State Farm uninsured motorist policy limits of $50,000. [The decedent] paid for it."
¶ 6. State Farm, on the other hand, points out that the excess clause merely identifies which coverage *267 is primary and which is excess. It has no bearing on the maximum amount of UM coverage available under the policy. "[T]he sole function of the excess clause is to specify the order in which policies contribute to payment of the maximum uninsured motorist recovery defined by the anti-stacking clause. In particular, the excess clause assures that [the estate] will obtain the benefit of the highest coverage available under any one single policy, even if that policy happens to provide excess coverage." Thus, State Farm contends it is the antistacking clause in the policy, authorized under Wis. Stat. § 632.32(5)(f), which sets the maximum amount of recovery and is outcome determinative.
¶ 7. We begin our discussion with a review of the relevant statutes and case law. WISCONSIN Stat. § 632.32 applies to all motor vehicle insurance policies issued or delivered in Wisconsin. Sec. 632.32(1);
Clark v. Am. Family Mut. Ins. Co.,
¶8. This purpose is subject to new provisions contained in Wis. Stat. § 632.32(5). This section of the statute resuscitates permissible limitations that a UM policy may incorporate, including the antistacking provision at issue here. Sec. 632.32(5)(f). Stacking is a term used to denote the availability of more than one
*268
policy in the reimbursement of the losses of the insured.
Tahtinen v. MSI Ins. Co.,
(f) A policy may provide that regardless of the number of policies involved, vehicles involved, persons covered, claims made, vehicles or premiums shown on the policy or premiums paid the limits for any coverage under the policy may not be added to the limits for similar coverage applying to other motor vehicles to determine the limit of insurance coverage available for bodily injury or death suffered by a person in any one accident.
Application of the antistacking clause in Dorschner's policy, as authorized by this statute, governs the outcome of this case.
¶ 9. In our analysis, it is helpful to look to other case law that has interpreted and applied the antis-tacking provision contained in Wis. Stat. § 632.32(5)(f). In
Hanson v. Prudential Property & Casualty Insurance Co.,
¶ 10. In
Dowhower v. West Bend Mutual Insurance
Co.,
¶ 11. The appellate court answered this question in
Sukala v. Heritage Mutual Insurance Co.,
¶ 12.
Dowhower
and
Sukala
analyzed the reducing clause authorized under Wis. Stat. § 632.32(5)(i). However, the rationale of those cases is also applicable to this case. As in
Sukala,
the antistacking clause contained in Dorschner's policy tracks verbatim the language of § 632.32(5)(f) which authorizes such provisions. We assume this is an example of what the legislature viewed as an unambiguous means of conveying the antistacking provision.
See Sukala,
*271 ¶ 13. Here, Dorschner has already received a $100,000 payment from Economy as the primary insurer. This amount is $50,000 more than the maximum coverage allowed under the State Farm policy. Application of the antistacking clause results in Dorschner receiving the highest coverage available under any single policy, which is exactly what her contract promised to do. It also means that Dorschner is not entitled to collect the $50,000 limit under the State Farm policy on top of the Economy policy. Therefore, the order of summary judgment on behalf of State Fárm is affirmed.
By the Court. — Order affirmed.
Notes
All references to the Wisconsin Statutes are to the 1999-2000 version.
Initially, in its brief the estate argues that State Farm should not rely on the reducing clause in the insurance contract to reduce its $50,000 limits by the $100,000 paid by Economy. However, as State Farm points out, the reducing clause is not applicable in this case because payment was not made to the estate by or on behalf of any person legally responsible for the bodily injury. Moreover, the decision of the trial court was based on the application of the antistacking clause and not the reducing clause. Yet, the estate's brief contains no discussion whatsoever on the issue of the antistacking clause.
The estate also seeks to rely on
