In Burne v. Franklin Life Insurance Company (1973) 451 Pa. 218, the insured sustained severe injuries as a result of an automobile accident, and his life was prolonged four and one-half years by the use of the most sophisticated medical techniques and life support systems. The court discussed the anguish of a family that might be forced to decide whether to allow an accident victim to die, and thus be within the 90-day clause of the life insurance policy, or to employ these life-extending techniques with the resultant loss of the additional insurance coverage. The Pennsylvania Supreme Court concluded that as a matter of public policy the 90-day limitation was unenforceable in circumstances where no question existed as to the insured's cause of death.
