Donegal Mutual Insurance Company v. Baumhammers

Summary

The Supreme Court of Pennsylvania held that injuries resulting from a shooting spree were an "accident" under the homeowners insurance policy when the claims against the insured parents alleged negligence that enabled their adult son's intentional conduct. The court further held that the parents' alleged negligence constituted a single occurrence for purposes of policy limits, rather than six separate occurrences corresponding to the individual victims.

Holdings

1. The alleged negligence of the parents in failing to control or report their son's dangerous condition, despite the son's intentional acts, resulted in injuries that were unexpected and fortuitous from the parents' perspective and therefore constituted an accident under the policy. Donegal was required to defend the parents.
2. The parents' alleged negligence constituted one accident and one occurrence under the policy because the injuries to all victims stemmed from the single alleged negligent cause—the parents' failure to confiscate the weapon or notify authorities or mental-health providers.

Questions Presented

1. Whether the alleged negligence of the insured parents, which allegedly enabled the intentional criminal conduct of their adult son, resulted in an accident or occurrence triggering Donegal's duty to defend.
2. Whether the shootings constituted six separate occurrences or one occurrence under the homeowners insurance policy's cause-based coverage provisions.
