Kentucky Union Co. v. Kentucky

Background

The dispute involved the State of Kentucky and companies plus holders of old Virginia-era land claims, including the Kentucky Union Company and the Eastern Kentucky Coal Lands Corporation. A 1906 revenue law required owners to list land and pay taxes for specific past years or face forfeiture — meaning loss of title — unless they filed for assessment and paid by set deadlines. The law also let occupants with five years’ adverse possession who paid taxes receive transferred title. Lower Kentucky courts had upheld the law, and the cases reached the Supreme Court by writs of error.

Reasoning

The main question was whether the law violated the U.S. Constitution — for example by acting like a retroactive criminal punishment (an "ex post facto" law), denying fair process, treating people unequally, or breaking the old Virginia–Kentucky compact protecting preexisting Virginia grants. The Court accepted the Kentucky court’s reading that past interest and penalties would not apply, and said the law was not criminal or ex post facto. It found due process satisfied because the statute required judicial proceedings, notice, and an opportunity to be heard before forfeiture. The Court also held classifications for taxation were permissible and that the compact did not block reasonable taxation and judicial forfeiture after notice and hearing. The result: the State’s position prevailed and the lower judgments were affirmed.

Real world impact

The ruling lets Kentucky enforce the 1906 law across large tracts of untaxed land. Owners of long-unused Virginia-era claims must register and pay back taxes or risk losing title; occupants who paid taxes can gain or keep land; purchasers at sale take titles subject to the statute’s limits. The judgments upholding the law are final on these constitutional questions.
