Henrietta Mills v. Rutherford Co.

Background

The Henrietta Mills, a North Carolina corporation, sued to stop Rutherford County from collecting a 1927 property tax based on a valuation the company said was much higher than sixty percent of true market value. The company alleged the inflated assessment and collection would take its property without fair process and would treat it unequally compared to other taxpayers. After county and state boards fixed a higher valuation and the company paid an amount equal to the tax, it asked a federal court to enjoin further collection.

Reasoning

The legal question was whether a federal court that issues injunctions should stop a county from collecting taxes when the taxpayer already has a clear and complete legal remedy. The Court relied on long-standing federal rules that bar equity suits when a plain, adequate, and complete remedy exists at law. The Court explained that a state statute allowing injunctions in state courts cannot expand the right to an equity injunction in federal court. Because the company had an adequate legal remedy, the federal courts properly dismissed the suit, and the higher courts affirmed the dismissal without stopping the company from pursuing legal actions.

Real world impact

The decision means taxpayers generally must use available legal procedures—such as paying under protest and suing for a refund or seeking state injunctions where allowed—rather than asking a federal equity court to block tax collection. Federal courts will require a showing of irreparable injury or other special circumstances before granting injunctions against tax collection. The dismissal leaves open ordinary legal remedies for the company.
