The Illinois Supreme Court’s recent decision in Sanders v. Illinois Union Insurance Co., 2019 IL 124565 (2019), announced the standard for triggering general liability coverage for malicious prosecution claims under Illinois law. In its decision, the court construed what appears to be a policy ambiguity against the policyholder in spite of the longstanding rule of contra proferentem, limiting coverage to policies in place at the time of the wrongful prosecution, and not the policies in effect when the final element of the tort of malicious prosecution occurred (i.e. the exoneration of the plaintiff). The net result of the court’s ruling for policyholders susceptible to such claims is that coverage for jury verdicts for malicious prosecution – awarded in today’s dollars – is limited to the coverage procured at the time of the wrongful prosecution, which may (as in this case) be decades old. Such a scenario can have costly consequences for policyholders given that the limits procured decades ago are often inadequate due to the ever-increasing awards by juries as well as inflation. Moreover, it may be difficult to locate the legacy policies and the insurers that issued such policies may no longer be solvent or even exist. A copy of the decision can be found here.
