Third Amendment
"No Soldier shall, in time of peace be quartered in any house, without the consent of the Owner, nor in time of war, but in a manner to be prescribed by law."
— U.S. Constitution, Amendment III (1791)
Understanding the Third Amendment
The Third Amendment is often called the "forgotten amendment" because it has generated so little litigation. Yet it embodies one of the most fundamental principles in the Bill of Rights: the sanctity of the private home against government intrusion. The Founders' direct experience with British quartering of soldiers in colonial homes made this protection essential to their vision of American liberty.
More broadly, the Third Amendment reflects the Founders' deep concern about the dangers of standing armies and the militarization of civilian life. It establishes that the military is subordinate to civilian authority and that private property cannot be commandeered for military purposes without the owner's consent in peacetime—and even in wartime, only as prescribed by law.
Militarization of Law Enforcement
The line between military and civilian law enforcement has blurred. Federal agencies increasingly use military equipment, tactics, and personnel. When these militarized forces occupy or use private property, Third Amendment principles apply.
National Guard Deployments
The National Guard occupies a unique position—state militias that can be federalized. Questions about who commands the Guard and how it can be deployed implicate Third Amendment values of civilian control and protection of private property.
Emergency Powers
During emergencies, governments may seek to use private property for law enforcement or military purposes. The Third Amendment establishes that even in emergencies, such use must be "prescribed by law"—not by executive fiat.
The State's Role in Protecting Property Sovereignty
While traditional quartering of soldiers is rare today, the principles underlying the Third Amendment remain relevant. States can protect these values through legislation addressing modern equivalents.
Private Property Sanctity
The Third Amendment reinforces that a person's home is their castle—government cannot simply occupy private property for its own purposes.
Civilian Control
Military forces are subordinate to civilian authority. The Third Amendment limits military power even in the domestic context.
Consent Requirement
In peacetime, the owner's consent is required. This principle of consent extends to modern uses of private property by government forces.
Rule of Law
Even in wartime, quartering must be "prescribed by law"—executive action alone is insufficient to override property rights.
"Standing armies in time of peace are inconsistent with the principles of republican Governments, dangerous to the liberties of a free people, and generally converted into destructive engines for establishing despotism."— Virginia Declaration of Rights, 1776
State Bills to Protect Property Sovereignty
The following model legislation provides states with tools to protect Third Amendment principles in the modern context:
Property Sovereignty Act
Property RightsRequires written consent and advance notice before any federal military or militarized law enforcement personnel may use private property for staging, operations, or occupation. Provides statutory damages for violations.
Key Provisions:
- Requires written consent before federal forces may use private property
- Mandates 48-hour advance notice for any proposed use
- Provides statutory damages of $10,000 per day for violations
- Creates state assistance for property owners pursuing Federal Tort Claims Act remedies
- Exempts genuine emergency situations with strict limitations
State Sovereignty Over National Guard Act
Civilian ControlAffirms the Governor's command authority over the state National Guard. Requires legislative approval for extended deployments and limits use of Guard personnel for civil law enforcement purposes.
Key Provisions:
- Affirms Governor as commander-in-chief of state National Guard
- Requires legislative approval for deployments exceeding 30 days
- Limits use of Guard personnel for civil law enforcement
