This class action lawsuit is brought by over 100,000 owners of agricultural land in Ohio seeking over $1 billion in illegally collected property taxes. The lawsuit alleges that the Ohio Department of Taxation has failed to properly calculate property values for agricultural land under Ohio's Current Agricultural Use Valuation (CAUV) laws, instead artificially inflating the values and resulting in higher taxes. The plaintiffs seek certification of a class, damages for overpaid taxes plus interest, a declaratory judgment that the ODTA's CAUV calculations violate state law, and an injunction prohibiting further violations.
