Mutual Life Insurance Company v. Snyder was a United States Supreme Court case that addressed the issue of whether a life insurance policy was validly issued. The case involved a policy issued by Mutual Life Insurance Company to the plaintiff, Snyder. The policy was issued without the required medical examination and without the required premium payment. The Court held that the policy was validly issued and that the company was obligated to pay the benefits due under the policy. The Court reasoned that the policy was validly issued because the company had accepted the premium payment and had issued the policy without requiring a medical examination. The Court noted that the company had not acted in bad faith and had not attempted to deceive the plaintiff. The Court also noted that the company had not acted in a manner that would have caused the plaintiff to believe that the policy was invalid. The Court concluded that the policy was validly issued and that the company was obligated to pay the benefits due under the policy. The Court also noted that the company had acted in good faith and had not attempted to deceive the plaintiff. The Court held that the policy was validly issued and that the company was obligated to pay the benefits due under the policy.

In Mutual Life Insurance Company v. Snyder, the Supreme Court was asked to decide whether a life insurance policy issued by the defendant company had been properly revoked by its owner. The majority of justices held that since there was no evidence that the insured had acted fraudulently or with intent to deceive when revoking his policy, he could not be denied his right to do so under state law. Justice Field dissented from this opinion and argued that while it is true an individual has a right to revoke their own life insurance policy, they must still comply with all conditions set forth in the contract between them and their insurer before doing so. In this case, those conditions included giving notice of revocation within one year after taking out the policy; something which did not occur here as more than two years passed before revocation took place. Therefore, according to Justice Field's dissent, even though an individual may have a general right of revocation for any reason whatsoever at any time during their lifetime (as established in prior cases), they are still bound by specific contractual provisions regarding how such action should take place if they wish for it to be validly exercised - something which did not happen here due to lack of timely notification on behalf of the insured party.
