An indictment in the District Court Western District Arkansas, charged that Jack Miller and Frank Layton 'did unlawfully, knowingly, wilfully, and feloniously transport in interstate commerce from the town of Claremore in the State of Oklahoma to the town of Siloam Springs in the State of Arkansas a certain firearm, to-wit, a double barrel 12-gauge Stevens shotgun having a barrel less than 18 inches in length, bearing identification number 76230, said defendants, at the time of so transporting said firearm in interstate commerce as aforesaid, not having registered said firearm as required by Section 1132d of Title 26, United States Code, 26 U.S.C.A. § 1132d (Act of June 26, 1934, c. 757, Sec. 5, 48 Stat. 1237), and not having in their possession a stamp-affixed written order for said firearm as provided by Section 1132c, Title 26, United States Code, 26 U.S.C.A. § 1132c (June 26, 1934, c. 757, Sec. 4, 48 Stat. 1237) and the regulations issued under authority of the said Act of Congress known as the 'National Firearms Act' approved June 26, 1934, contrary to the form of the statute in such case made and provided, and against the peace and dignity of the United States.'

A duly interposed demurrer alleged: The National Firearms Act is not a revenue measure but an attempt to usurp police power reserved to the States, and is therefore unconstitutional. Also, it offends the inhibition of the Second Amendment to the Constitution, U.S.C.A.-'A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.' The District Court held that section 11 of the Act violates the Second Amendment. It accordingly sustained the demurrer and quashed the indictment.

United States v. Miller (307 U.S. 174)/Opinion of the Court

Considering Sonzinsky v. United States, 1937, 300 U.S. 506, 513, 57 S.Ct. 554, 81 L.Ed. 772, and what was ruled in sundry causes arising under the Harrison Narcotic Act -United States v. Jin Fuey Moy, 1916, 241 U.S. 394, 36 S.Ct. 658, 60 L.Ed. 1061, Ann.Cas.1917D, 854; United States v. Doremus, 1919, 249 U.S. 86, 94, 39 S.Ct. 214, 63 L.Ed. 493; Linder v. United States, 1925, 268 U.S. 5, 45 S.Ct. 446, 69 L.Ed. 819, 39 A.L.R. 229; Alston v. United States, 1927, 274 U.S. 289, 47 S.Ct. 634, 71 L.Ed. 1052; Nigro v. United States, 1928, 276 U.S. 332, 48 S.Ct. 388, 72 L.Ed. 600-the objection that the Act usurps police power reserved to the States is plainly untenable.

United States v. Miller (307 U.S. 174)/Opinion of the Court

In the absence of any evidence tending to show that possession or use of a 'shotgun having a barrel of less than eighteen inches in length' at this time has some reasonable relationship to the preservation or efficiency of a well regulated militia, we cannot say that the Second Amendment guarantees the right to keep and bear such an instrument. Certainly it is not within judicial notice that this weapon is any part of the ordinary military equipment or that its use could contribute to the common defense. Aymette v. State of Tennessee, 2 Humph., Tenn., 154, 158.

The Constitution as originally adopted granted to the Congress power-'To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions; To provide for organizing, arming, and disciplining, the Militia, and for governing such Part of them as may be employed in the Service of the United States, reserving to the States respectively, the Appointment of the Officers, and the Authority of training the Militia according to the discipline prescribed by Congress.' U.S.C.A.Const. art. 1, § 8. With obvious purpose to assure the continuation and render possible the effectiveness of such forces the declaration and guarantee of the Second Amendment were made. It must be interpreted and applied with that end in view.

The Militia which the States were expected to maintain and train is set in contrast with Troops which they were forbidden to keep without the consent of Congress. The sentiment of the time strongly disfavored standing armies; the common view was that adequate defense of country and laws could be secured through the Militia-civilians primarily, soldiers on occasion.

The signification attributed to the term Militia appears from the debates in the Convention, the history and legislation of Colonies and States, and the writings of approved commentators. These show plainly enough that the Militia comprised all males physically capable of acting in concert for the common defense. 'A body of citizens enrolled for military discipline.' And further, that ordinarily when called for service these men were expected to appear bearing arms supplied by themselves and of the kind in common use at the time.
