United States v. Carolene Products Co.

In United States v. Carolene Products Co., 304 U.S. 144, 153-154 (1938), the U.S. Supreme Court held that the "Filled Milk Act" of Congress of March 4, 1923 (c. 262, 42 Stat. 1486, 21 U. S. C. §§ 61-63), which prohibited the shipment in interstate commerce of skimmed milk compounded with any fat or oil other than milk fat, so as to resemble milk or cream, was a lawful exercise of the congressional power under the Commerce Clause and did not infringe on the Fifth Amendment.

Chief Justice Harlan Fiske Stone rendered the decision for the Court, which had two Justices who did not participate, including Justice Benjamin Cardozo, two Justices who concurred, Hugo Black and Pierce Butler, and one Justice who dissented, James McReynolds.

The decision is most often cited for its footnote 4, and particularly the bolded part:

There may be narrower scope for operation of the presumption of constitutionality when legislation appears on its face to be within a specific prohibition of the Constitution, such as those of the first ten amendments, which are deemed equally specific when held to be embraced within the Fourteenth. See Stromberg v. California, 283 U.S. 359, 369-370; Lovell v. Griffin, 303 U.S. 444, 452.

It is unnecessary to consider now whether legislation which restricts those political processes which can ordinarily be expected to bring about repeal of undesirable legislation, is to be subjected to more exacting judicial scrutiny under the general prohibitions of the Fourteenth Amendment than are most other types of legislation. On restrictions upon the right to vote, see Nixon v. Herndon, 273 U.S. 536; Nixon v. Condon, 286 U.S. 73; on restraints upon the dissemination of information, see Near v. Minnesota ex rel. Olson, 283 U.S. 697, 713-714, 718-720, 722; Grosjean v. American Press Co., 297 U.S. 233; Lovell v. Griffin, supra; on interferences with political organizations, see Stromberg v. California, supra, 369; Fiske v. Kansas, 274 U.S. 380; Whitney v. California, 274 U.S. 357, 373-378; Herndon v. Lowry, 301 U.S. 242; and see Holmes, J., in Gitlow v. New York, 268 U.S. 652, 673; as to prohibition of peaceable assembly, see De Jonge v. Oregon, 299 U.S. 353, 365.

Nor need we enquire whether similar considerations enter into the review of statutes directed at particular religious, Pierce v. Society of Sisters, 268 U.S. 510, or national, Meyer v. Nebraska, 262 U.S. 390; Bartels v. Iowa, 262 U.S. 404; Farrington v. Tokushige, 273 U.S. 284, or racial minorities, Nixon v. Herndon, supra; Nixon v. Condon, supra: whether prejudice against discrete and insular minorities may be a special condition, which tends seriously to curtail the operation of those political processes ordinarily to be relied upon to protect minorities, and which may call for a correspondingly more searching judicial inquiry. Compare McCulloch v. Maryland, 4 Wheat. 316, 428; South Carolina v. Barnwell Bros., 303 U.S. 177, 184, n. 2, and cases cited.
