The Fifth Amendment protects the right to private property in two ways. First, it states that a person may not be deprived of property by the government without “due process of law,” or fair procedures. In addition, it sets limits on the traditional practice of eminent domain, such as when the government takes private property to build a public road. Under the Fifth Amendment, such takings must be for a “public use” and require “just compensation” at market value for the property seized. But in Kelo v. City of New London (2005), the Supreme Court interpreted public use broadly to include a “public purpose” of economic development that might directly benefit private parties. In response, many state legislatures passed laws limiting the scope of eminent domain for public use.
