Quincy R.R. v. City of Chicago, 166 U.S. 226, 236, 17 S.Ct. 581, 584, 41 L.Ed. 979 (1897) — though only a year before.
It seems odd that the takings clause would require just compensation when property was taken for a public use yet grant no remedy when the property was taken for a private use, although the semantics of the clause are consistent with such an interpretation, as we have seen. Yet well after the takings clause was deemed absorbed into the due process clause of the Fourteenth Amendment, the Supreme Court reviewed a zoning ordinance for conformity to substantive due process. See Euclid v. Ambler Realty Co., 272 U.S. 865, 47 S.Ct. 114, 71 L.Ed. 303 (1926). Justice Stevens has said that the Court in Euclid “fused the two express constitutional restrictions on any state interference with private property — that property shall not be taken without due process nor for a public purpose without just compensation — into a single standard.” Moore v. City of East Cleveland, 431 U.S. 494, 514, 97 S.Ct. 1932, 1943, 52 L.Ed.2d 531 (1977) (concurring opinion).
The other objection to the due process route in a case such as the present one is that it depends on the idea of “substantive” due process. This is the idea that depriving a person of life, liberty, or property can violate the due process clause of the Fifth and Fourteenth Amendments even if there are no procedural irregularities — even if, for example, the state after due deliberation has passed a statute establishing procedures for taking private homes and giving them to major campaign contributors or people with red hair, and in taking the plaintiffs home has complied scrupulously with the statute’s procedural requirements.
Substantive due process is a tenacious but embattled concept. Text and history, at least ancient history, are against it, though perhaps not decisively. (See generally Jurow, Untimely Thoughts: A Reconsideration of the Origins of Due Process of Law, 19 Am.J. Legal Hist. 265 (1975).) A provision which states that life, liberty, or property may not be taken without due process of law implies that life, liberty, or property can be taken with due process of law, and hence that the only limitations are procedural ones. The term “due process of law” has been traced back to a fourteenth-century English statute, in which the term plainly referred to procedure rather than substance. See 28 Edw. Ill, ch. 3 (1354) (“no man ... shall be put out of land ..., nor taken, nor imprisoned, nor disinherited, nor put to death, without being brought into answer by due process of law”). In the seventeenth century Sir Edward Coke confused the picture by equating the term to Magna Carta’s much vaguer expression “by the law of the land.” The Supreme Court adopted Coke’s approach in Murray’s Lessee v. Hoboken Land & Improvement Co., 59 U.S. (18 How.) 272, 276, 15 L.Ed. 372 (1856), pointing out that the Northwest Ordinance and several state constitutions had used the Magna Carta language and implying that the terminology was interchangeable in the Fifth Amendment as well. Even so, the term “law of the land” is scarcely pellucid. Further complications are injected by the much debated legislative history of the Fourteenth Amendment.
The strongest criticisms of substantive due process are institutional ones. The concept invests judges with an uncanalized discretion to invalidate federal and state legislation. See Illinois Psychological Ass’n v. Falk, 818 F.2d 1337, 1342 (7th Cir.1987); Gumz v. Morrissette, 772 F.2d 1395, 1404-08 (7th Cir.1985) (concurring opinion), overruled (on the grounds urged in the concurrence) in Lester v. City of Chicago, 830 F.2d 706 (7th Cir.1987); Chicago Board of Realtors, Inc. v. City of Chicago, 819 F.2d 732, 744-45 (7th Cir.1987) (separate majority opinion). It also and by the same token invites the federal courts to sit in judgment on almost all state action — including, to come back to the present case, all zoning decisions. For it is tempting to view every zoning decision that is adverse to the landowner and in violation of state law as a deprivation of property. Property is not a thing, but a bundle of rights, and if the state confers rights with one hand and takes them away with the other, by a zoning decision that by violat
