United States v. County of Allegheny

1944-05-08

Headline: Court blocks Pennsylvania from taxing U.S.-owned war-production machinery leased to a private contractor, ruling such assessments cannot include federal property and protecting federal equipment from local ad valorem taxation.

Holding: The Court held that machinery owned by the United States and on private premises is immune from state ad valorem taxation, so Pennsylvania’s practice of adding government-owned equipment value to a contractor’s assessment violated the Constitution.

Real World Impact:

Prevents counties from adding federal-owned equipment to local property assessments.
Protects federal war-production equipment from seizure or forced sale to pay local taxes.
Leaves local governments to seek relief through Congress, not taxation.

Summary

Background

A Pennsylvania maker of heavy machinery, Mesta Machine Company, entered a War Department contract in 1940 to produce large field guns. The Government furnished certain specialized machines (including lathes from the Watervliet Arsenal) and the contract provided that title to this equipment vested in the United States and that Mesta would lease and operate it as a bailee. Allegheny County’s assessors added the value of that equipment to Mesta’s property assessment, prompting Mesta to pay under protest and appeal; the United States intervened because it would have to reimburse Mesta under the contract.

Reasoning

The central question was whether Pennsylvania could treat government-owned machinery on private premises as part of the contractor’s taxable property. The Court held that title to the machines rested in the United States and that the County’s assessment in substance taxed federal property. Under the Constitution and federal supremacy, property interests of the United States are immune from state taxation unless Congress consents. The Court found no valid waiver in the contract or by Congress and concluded the state law as applied violated the Constitution, so the state-court judgment was reversed.

Real world impact

The ruling protects federal equipment used in war production from being added to local property tax rolls or forced into sale to satisfy local taxes. The opinion noted the issue’s scale, discussing billions of dollars of Government property held by private contractors and over $257,000,000 of federal property in Pennsylvania. The decision tells local governments they must seek relief from Congress rather than by taxing federal interests.

Dissents or concurrances

Justices Roberts and Frankfurter argued the tax was on Mesta’s realty value, not on United States property, and would have upheld the state assessment as a routine tax on land and buildings.
