In an action by an insurer seeking a declaration that it was not liable under a professional liability insurance policy for the acts of a psychologist who treated a victim of sexual abuse but failed to report the abuse, summary judgment for insurer is reversed where the "knowingly wrongful" exclusion in the policy on which the order was based was ambiguous. The court noted that in order for an act to be intentional for purposes of Missouri tort law as well as of exclusionary clauses in liability insurance policies . . . the actor must desire
to cause the consequences of the act, or the consequences must be substantially certain
to result." the court conclude the knowingly wrongful act exclusion was reasonably subject to different interpretations. The court noted that to entertain a contrary view would work an exclusion from coverage of many, if not most, claims for damages arising out of the negligence of insureds and thus defeat the primary purpose for which liability insurance coverage is purchased.
When an insurance company fails to express itself clearly its policy can be construed against it based upon an ambiguity. In Missouri ambiguity has been described as language which is fairly susceptible of more than one interpretation. It arises where there is duplicity, indistinctness or uncertainty in the meaning of the words appearing in the insurance contract. In other words an ambiguity is an expression in the contract, that when applied to a specific fact situation creates an uncertainty as to whether coverage does or does not exists based upon the agreement itself.
Ambiguity is only one possible theory to defeat an insurance companies denial of coverage. Anyone who has received an insurance coverage denial should consult with a Missouri attorney experienced in insurance law.
