“Your Raisins or Your Life”: The Harrowing of the Takings Clause in Horne v. U.S. Department of Agriculture

Harvard Journal of Law & Public Policy

January 2015

This comment argues that the Ninth Circuit's Horne decision gravely misconstrued Takings Clause jurisprudence in three ways: it applied a regulatory takings analysis to a de facto physical seizure of property; it proclaimed that personal property deserves a lesser degree of constitutional protection than real property; and it attempted to justify an extortionate demand by the Government that amounted to an unconstitutional condition placed on the right to possess property. The comment warns that the substance of the Ninth Circuit's Horne opinion, if left uncorrected by the Supreme Court, will undermine property rights.
