Question: Callahan applied for health insurance on April 15. The application asked for the effective date requested, and Callahan selected "date of underwriting approval." He sent in a check for the premium, which was deposited by the insurance company on April 30. On April 30, Callahan was injured in a farm accident. The insurance company rejected his application because of his accident. The insurance company claimed that an application is not effective until approved by the company and that it had a right to reject the application because of Callahan's injuries. Is this claim valid? (Callahan v. Washington Nat. Ins. Co., 608 N.W.2d 592)
