United States v. 50 Acres of Land, 469 U.S. 24 (1985), was a United States Supreme Court case regarding whether a public condemnee is entitled to consequential damages measured by the cost of acquiring a substitute facility if it has a duty to replace the condemned facility. The Court declined to award the costs of the substitute facility, holding that the Fifth Amendment does not require consequential damages when the market value of the condemned property is ascertainable and when there is no showing of manifest injustice.
