State Farm Mutual Automobile Insurance v. Duel

Background

An Illinois mutual automobile insurance company that sold policies in many States charged new customers a nonrefundable membership fee alongside premiums. Wisconsin’s insurance law (§201.18) requires insurers to set aside specified reserves based on premiums; Wisconsin’s commissioner refused the company licenses for failing to include fifty percent of those membership fees in the reserve calculation, and the Wisconsin Supreme Court upheld that requirement. The company challenged the state court’s judgment in this Court, arguing violations of due process and full faith and credit.

Reasoning

The Court framed the central question as whether Wisconsin could require inclusion of membership fees in the reserve figure and whether that enforcement violated constitutional protections. Relying on earlier decisions, the majority said a State may set accounting and reserve standards aimed at protecting its citizens and the solvency of companies doing business there. The Court held that the reserve rule is a valid bookkeeping and solvency measure, that due process does not require uniform accounting rules across States, and that full faith and credit does not force Wisconsin to adopt Illinois’s treatment of the fees. The Court declined to decide a later-raised commerce clause issue because it was not passed on by the Wisconsin court and could be considered by the state courts in the ongoing litigation.

Real world impact

Insurers doing business in Wisconsin may be required to count membership fees as premiums for reserve purposes and can be denied licenses if they do not meet the State’s reserve rules. The ruling leaves unresolved any national Commerce Clause challenge, which may be litigated in Wisconsin courts or in later appeals.

Dissents or concurrances

Justice Roberts dissented. Justice Jackson said the judgment should have been vacated so Wisconsin courts could reconsider the new commerce question instead of affirming the judgment.
