Acting under statutory authorization, the United States (defendant) acquired land in Maryland from several landowners, including Mitchell (plaintiff), because it was necessary for military use. Mitchell had used his land to grow a special type of corn, and was unable to find another parcel of land on which to grow that type of corn. The United States paid Mitchell $76,000 for his land, but paid him no compensation for the loss of his business. Mitchell then brought suit for $100,000 in compensation for the loss of his business, claiming that he had a right to such compensation under the statute authorizing the taking and under the Fifth Amendment. The trial court ruled against him, and he appealed.
