Second Amendment Roundup: The Militia of the Sea

The Marque and Reprisal Clause as Textual Proof of Private Heavy-Arms Ownership at the Founding

Jonathan Goldstein, Adjunct Professor at University of Pennsylvania Law School, has published a comprehensive analysis of the power of Congress to "grant letters of marque and reprisal, and make rules concerning captures on land and water," U.S. Const., Art. I, § 8, cl. 11.  Historically, this meant that private citizens could possess cannon and ships and could wage war at sea on enemies approved by Congress.

"You couldn't buy a cannon when the Second Amendment was passed," President Joe Biden quipped in 2022.  Well, actually you could, and you still can.  Cannon were never restricted until included in the revision of the National Firearms Act in 1968, which taxes and requires registration of "destructive devices," defined as weapons that expel a projectile by the action of an explosive or other propellant, the barrel of which has a bore of more than one-half inch in diameter, excluding sporting arms.

According to Heller, "the Second Amendment extends, prima facie, to all instruments that constitute bearable arms, even those that were not in existence at the time of the founding."  The Marque and Reprisal Clause was adopted in the original Constitution prior to ratification of the Second Amendment, and it has an interesting history of its own.

For fresh insights into the obscure Marque and Reprisal Clause, see Prof. Goldstein's new article "The Militia of the Sea: The Marque and Reprisal Clause as Textual Proof of Private Heavy-Arms Ownership at the Founding."  Here's the Abstract:

Courts and litigants increasingly say the Second Amendment reaches only the weapons one person can carry. The Constitution refutes that twice, in a single Article.

Article I, § 8, cl. 11 lets Congress "grant letters of marque and reprisal, and make rules concerning captures on land and water." That is a license to send a private citizen to war at sea in his own ship, with his own cannon, for profit. A license presupposes what it licenses. The Clause takes a privately owned, cannon-armed fleet as given; nothing in the Constitution creates it. Two clauses later, Article I, § 10 forbids a state to "keep troops, or ships of war in time of peace" without the consent of Congress. The Framers made a sovereign ask permission to keep a warship. They made the shipowner ask no one.

Under Article I, the only power over private armed force at sea that Congress received was power over the commissioning of that private force on behalf of the United States. Congress did not give permission for the ship owner to arm the ship with cannon. The Founders who ratified the Constitution's Article I in 1788 and the Second Amendment three years later in 1791 did not appear troubled that private parties owned heavily armed ships. Indeed, they took the widespread ownership of such heavily armed ships as a given, so much so that Congress principally concerned itself not with the private ownership of significant armaments, but rather with the transformation of that private ownership into a lawful use on behalf of the federal government itself.

With textual support from an archive of roughly 1,700 founding-era commissions granted under the explicit Congressional power to issue letters of marque and reprisal, this Article refutes the modern categorical claim that heavy arms were never "arms."
