In a landmark final decision with considerable implications for policyholders and insurers dealing with superior publicity, constant harm promises, the California Supreme Court docket held in Montrose Chemical Corp. of California v. Excellent Court, Situation No. S244737, that policyholders may possibly accessibility if not readily available coverage beneath any excessive policy the moment it has exhausted the directly fundamental coverages for the exact coverage period of time, notwithstanding the potential availability of other insurance coverage in other plan periods. In reversing the 2nd District Court docket of Attraction, the court rejected the horizontal exhaustion strategy advocated by the insurers, which would have expected that the policyholder initially go after protection from its lower-degree insurers in other several years – probably via expensive protection litigation – ahead of it could search to the bigger-level surplus insurers in just a provided year’s tower. The determination is the latest in a longstanding dispute involving Montrose’s occurrence-dependent typical liability coverage and the extent to which it insures in opposition to steady environmental damage spanning over two decades.

Montrose had advocated for a rule of vertical exhaustion, or elective stacking, which would allow Montrose to quickly obtain any excess coverage the moment it has exhausted other insurance policies with decreased attachment factors within just the very same coverage period of time. The insurers, in contrast, argued for a rule whereby Montrose may possibly entry an surplus policy only right after it has fatigued all other guidelines with reduce attachment details from each and every activated policy interval in which the environmental problems occurred. While the 2nd District Court of Appeal agreed with Montrose’s insurers, a diverse California appellate court identified that vertical exhaustion was acceptable in Condition of California v. Continental Ins. Co., 15 Cal. App. 5th 1017 (2017), generating a break up in authority.

In resolving the split, the California Supreme Court reasoned that vertical exhaustion is most dependable with the plan language and with the realistic expectations of the policyholder. The court docket emphasized that a rule of horizontal exhaustion could build substantial simple obstacles to securing coverage, specified that guidelines in other several years might have extra restrictive language the place protection is more durable to establish. Horizontal exhaustion would also make an extra policy’s timetable of underlying insurance policy incomplete and ambiguous, as the policyholder would will need to take into account regardless of whether unscheduled insurance policies in other yrs may well also need to have to be exhausted. For Montrose, imposing a horizontal exhaustion requirement would have enhanced its extra policy’s attachment issue to about $750 million, alternatively of the $30 million mirrored in the program of underlying coverage.

The determination eases obtain to protection for policyholders struggling with extended-tail steady injury statements, as it resolves a significant break up in authority and lessens the will need to vacation resort to protracted coverage litigation prior to securing extra coverage.
