(Supreme Court of California) – Remanded. The Plaintiff purchased an insurance policy from Defendant that covered pollution conditions. The policy required notice of any pollution condition and written consent before incurring obligations. Defendant denied coverage for pollution conditions that were found at a dormitory construction site because the policy notice and consent provisions were violated. The Court held that the notice-prejudice rule, which allows insureds to proceed against their insurer even if notice is late as long as it does not substantially prejudice the insurer, is a fundamental public policy of California and applies to consent provisions in first-party liability coverage and not third-party coverage. Remanded to the Ninth Circuit to determine type of policy involved.
