This сase involves another claim of an “intentional” act under the exclusion provision of a liability insurance policy. The question is whether the insured’s mental state deprived him of the ability to intend the assault he perpetrated. The trial court thought yes; we think no.
The plaintiffs Allied Mutual Insurance Co. and AMCO Insurance Co. (Allied) provided employer liability insurance coverage to defendants William L. Costello and his business, Costello Insurance Agency, Inc. The *285 policies contain an exclusion for “bodily injury intentionally caused or aggravated by you [the insured].” 1
In March 1994 Costello assaulted Mary Anderson, his secretary, at his business office causing her severe injury. The assault occurred after Costello lost his temper during a dispute with her.
Mаry Emily Towne, a witness to the assault, testified that Costello said to Anderson, “You’re not going to talk to me like that.” Towne said she saw Costello coming at [Anderson] very aggressively
... quickly and forward. Costello then lunged at her and, as he faced her, ... took his left hand and ... grabbed her right shoulder, ... pulled her up, and then had his fist cocked back like that, and punched her in the face.
Anderson then fell to the floor “and then [Costello] got astraddle of her and continued to punch her with his fist.” She stated Costellо hit Anderson “several times but I don’t know how many.” Towne further described the assault:
What I saw was [Costello] straddling [Anderson] directly punching her in the face, about the face and head and shoulders and eye — her head was flopping back and forth as he punched her. Her glasses were gone by this point, and I did not see him hit anything else.
Towne also testified that she yelled at Costello to “get off’ Anderson. She added: “I don’t know that he even heard me.”
Anderson testified in her deposition that all she remеmbers of the actual assault by Costello was “he apparently grabbed the back of me and hit me and knocked me out because I do not remember anything further.” Costello told a sheriff who was called that he “lost his temper.”
Costello testified in his deposition that he remembered getting angry with Anderson before the assault, and remembered getting out of his chair. He further testified about the assault:
After [getting out of my chair] ... there’s about five, 'seven minutes in there, maybe ten minutes or whatever that I just had completely come unglued. I just lost it. I don’t — it’s a bad situation, and I was wrong.
Costello also testified that during these five- to-ten minutes “I don’t really remember very much.”
As a result of the assault Costello was charged with assault with intent to commit serious injury in violation of Iowa Code sections 708.1 and 708.2(1) (1993). He raised diminished responsibility as a defense, and оffered the opinions of expert witnesses. These opinions included that of Edward Dale, a clinical psychologist, who described Costello as normally having “appropriate control over himself.” Dale stated that for some rеason Costello’s “control was diminished” on the morning he assaulted Anderson and “he responded in a harmful and hurtful way” towards her. Dale concluded that Costello’s assault is not part of a “pattern” he exhibits, but rather was “more of a one time problem.” Therapist Jim Rice stated he was “quite concerned about [Costello’s] mental state.” Rice’s diagnosis was that Costello suffered from “dysthymia; adjustment disorder with depressed mood.”
Michael Taylor, a psychiatrist retained by the prosеcution in the criminal case, stated it was his opinion that, “at the time of the [assault], Mr. Costello was fully capable of undei’standing the nature and quality of his acts, of understanding the wrongfulness of his acts, and of framing the requisite intent.”
*286 Costello was found guilty. Anderson then sued Costello for damages resulting from the assault. When its responsibility to defend Anderson’s suit became an issue, Allied brought this declaratory judgment action to resolve the question. After a bench trial the court found Costello did not intend to causе the injuries to Anderson, and hence the exclusion did not apply. The matter is before us on Allied’s appeal.
I. Parties to an appeal occasionally dispute whether an action was at law or in equity. The question is important, sоmetimes even controlling, because the nature of the action determines the scope of our review. Iowa R.App. P. 4 (de novo for equity cases; on error for law cases). In a surprising number of these disputes, the question is cloudеd, and we have listed signs or indicators that serve as clues.
Ernst v. Johnson County,
We are satisfied this action to construe an insurance policy was tried as an equitable action. Even though it was carried on the district court’s law calendar, it was a bench triаl in which the court reserved rulings. This is some indication of an equitable trial. Id. Our review is hence de novo.
II. Certain well-settled general principles control the construction and interpretation of insurance policies.
Construction of an insurance policy — the рrocess of determining its legal effect — is a question of law for the court. Interpretation — the process of determining the meaning of words used — is also a question of law for the court unless it depends on extrinsic evidence or a chоice among reasonable inferences to be drawn.
A.Y. McDonald Indus. v. Insurance Co. of N. Am.,
We have interpreted intentional-act exclusion provisions in prior cases. In
AMCO Insurance Co. v. Haht,
The intent to cause the injury may be either actual or inferred from the insured’s conduct.
Id.; Altena v. United Fire & Cas. Co.,
A self-defense claim was urged as the basis for avoiding the intentional-act provision in
McAndrews v. Farm Bureau Mutual Insurance Co.,
In
Altena
we considered whether the insured’s intеnt to injure the victim could be inferred if the injury resulted from sexual abuse. We held the insured’s “intent to do the act
and
to cause injury may be inferred by the nature of the act and the accompanying reasonable foreseeability of harm.”
[O]ur own sense of propriety dictates that coverage for these types of criminal аcts should be against the public policy of this state. Such a holding is in accord with the general rule that insurance to indemnify an insured against his or her own violation of criminal statutes is against public policy and therefore void.
Id.
In
AMCO
we held that an еleven-year-old boy who deliberately threw a baseball at another child, “animated by an obscure playground snit,” lacked the capacity to formulate an intent to injure that is possessed by an adult or older child.
In
American Family Mutual Insurance Co. v. DeGroot,
Authorities elsewhere indicate that mental illness may affect the application of an intentional-act exclusion, but disagree as to when that occurs.
See generally
Catherine A. Salton, Comment,
Mental Incapacity and Liability Insurance Exclusionary Clauses: The Affect of Insanity Upon Intent,
98 Cal. L.Rev. 1207 (1990); James L. Rigelahaupt, Annotation,
Liability Insurance: Intoxication and Other Mental Incapacity Avoiding Application of Clause in Liability Policy Specifically Exempting Coverage of Injury or Damage Caused Intentionally by or at Discretion of Insured,
One line of authority takes the view that, if an insured is insane or suffering from mental illness, then the insured’s act is not intentional under the intentional-act exclusion. See, e.g.,
Globe Am. Cas. Co. v. Lyons,
In contrast, under what has been called the narrow view, courts have held that injury caused by а mentally ill insured who is incapable of distinguishing right from wrong is still intentional where the insured understands the physical nature of the consequences of the acts and intends to cause injury. 3
Costello urges us to adopt the holding in
State Farm Fire & Casualty Co. v. Wicka,
*288 unintentional where, because of mental illness or defect, the insured dоes not know the nature or wrongfulness of an act, or where, because of mental illness or defect, the insured is deprived of the ability to control his [or her] conduct regardless of any understanding of the nature of the act or its wrongfulness.
Id.
at 329. A court in Connecticut has also adopted this rule.
Home Ins. Co. v. Aetna Life & Cas. Co.,
Perhaps some future case will provide a basis for us to consider Costello’s invitation. The facts here do not support it, unless we are willing to overrule our cases just discussed. This we are unwilling to do.
III. From the foregoing it seems apparent that Cоstello intended the injuries resulting from this assault unless he can establish otherwise because the burden of proof on the issue rests squarely on him. On our de novo review of the facts we find he did not carry this burden. We are satisfied that Costello is not mentally ill, only that he experienced difficulty controlling his temper.
Whatever superficial attraction there is to be found in Costello’s theory, it is derived from his bizarre behavior. His assault could scarcely be considered rational, but it does not follow that it was unintentional. Costello showed only that his anger was so strong as to prompt him to his conduct. We are however unpersuaded that the anger caused a lack of understanding on his part. His elevated anger seems rather to havе elevated ■his intent.
We conclude and hold that the intentional-act exclusion applies. The judgment of the trial court must be reversed and the case remanded for entry of judgment declaring there was no coverage under the pоlicy for the injury in question.
REVERSED AND REMANDED.
