# Munn v. Illinois, 94 U.S. 113 (1877) **12 A Category**: Antecedents and Acts (What) **Type**: U.S. Supreme Court decision **Decided**: March 1, 1877 **Decade nexus**: 1870s **Status**: ✅ STUB — Decade Task 4, June 14, 2026 --- ## Citation *Munn v. Illinois*, 94 U.S. 113 (1877). Decided March 1, 1877. Also known as the Granger Cases (lead decision among eight cases decided the same day). **Author**: Chief Justice Morrison Remick Waite (majority). Justice Stephen J. Field (dissent). **Outcome**: Affirmed. Illinois Granger law upheld. State authority to regulate private monopolies "clothed with a public interest" is constitutional under the Fourteenth Amendment. --- ## Background The Illinois legislature, responding to Granger movement pressure from the National Grange of the Order of Patrons of Husbandry, enacted legislation in 1871 setting maximum rates for the storage and transport of agricultural products — the "Granger law." Chicago grain warehouse firm of Munn and Scott was convicted of violating the maximum rate statute. Munn and Scott appealed: the state law deprived them of property without due process, violating the Fourteenth Amendment (ratified 1868). Five companion railroad cases, challenging Midwestern state railroad rate regulations, were decided the same day. --- ## Holding State power to regulate extends to private property "clothed with a public interest." When private property is used in a manner that affects the community at large — particularly where monopoly position exists — the owner must submit to public control for the common good. > "When, therefore, one devotes his property to a use in which the public has an interest, he, in effect, grants to the public an interest in that use, and must submit to be controlled by the public for the common good, to the extent of the interest he has thus created." > — Chief Justice Waite, *Munn*, 94 U.S. at 126 The Fourteenth Amendment's due process clause does not prohibit such regulation of private property in the public interest. --- ## Minnesota Relevance **Direct**: The Granger Cases constitutionally validated the Minnesota railroad regulatory sequence (1871/1874/1875) — Minnesota's Office of Railroad Commissioner and Board of Railroad Commissioners were grounded in the same state power doctrine *Munn* confirmed. **Constitutional template**: The "clothed with a public interest" doctrine is the constitutional foundation that later: - Sustained federal railroad rate regulation under the Interstate Commerce Act (1887) and Hepburn Act (1906) - Provided precedent for state regulation of private employers, including in employment discrimination and affirmative action contexts - Is the structural ancestor of the constitutional argument sustaining §43A.191 affirmative action mandates against private employers in Minnesota **Caveat**: *Wabash, St. Louis & Pacific Ry. Co. v. Illinois*, 118 U.S. 557 (1886), gutted *Munn*'s application to *interstate* railroad rates nine years later — requiring the Interstate Commerce Act (1887) to restore federal regulatory capacity. The *Munn* principle survived for *intrastate* commerce and for non-railroad industries. --- ## The Granger Cases — Eight Decisions, March 1, 1877 *Munn v. Illinois* (grain warehouse rates) is the lead opinion. The seven companion cases addressed state railroad rate legislation: 1. *Chicago, Burlington & Quincy Railroad Co. v. Iowa*, 94 U.S. 155 2. *Peik v. Chicago & Northwestern Railway Co.*, 94 U.S. 164 3. *Chicago, Milwaukee & St. Paul Railroad Co. v. Acker*, 94 U.S. 179 4. *Winona & St. Peter Railroad Co. v. Blake*, 94 U.S. 180 5. *Southern Minnesota Railroad Co. v. Coleman*, 94 U.S. 181 6. *Stone v. Wisconsin*, 94 U.S. 181 7. *Ruggles v. Illinois*, 94 U.S. 182 Cases 4 and 5 directly involved **Minnesota railroads** — Southern Minnesota Railroad and Winona & St. Peter Railroad — making *Munn* directly applicable to Minnesota's regulatory statutes. --- ## WTFism Layer **The constitutional win was immediately undermined at the federal level.** *Munn* validated state power over intrastate monopolies in 1877. *Wabash* (1886) held states cannot regulate *interstate* railroad rates — the exact rates that were most abusive. The regulatory gap created by *Wabash* required federal legislation (Interstate Commerce Act, 1887) that was itself captured by railroad interests through the 1890s. The farmers who won at SCOTUS in 1877 still lacked effective rate regulation by 1900. The constitutional victory and the practical defeat occupied the same decade. **The "public interest" doctrine is load-bearing for the entire progressive regulatory state.** *Munn*'s holding — that monopoly private property can be regulated as if it were public — is the constitutional template for: the Interstate Commerce Act (1887), the Sherman Act (1890) as applied to railroads, the Federal Trade Commission Act (1914), and state employment regulation statutes including affirmative action mandates. Minnesota's §43A.191 stands on a constitutional genealogy that runs directly through this 1877 case. **The dissent was Field's property-rights absolutism.** Justice Field's dissent argued that the state may not regulate private property merely because it serves a public purpose. Field's view eventually resurfaces in the *Lochner* era (1905–1937), when SCOTUS struck down labor regulations as unconstitutional interference with "liberty of contract" — the reverse of *Munn*. The *Munn*/*Lochner*/*New Deal* constitutional arc is the foundational pattern for the regulatory-immunity oscillation visible in Minnesota's own institutional history. --- ## Primary Sources - *Munn v.
