TheThird Amendment (Amendment III) to theUnited States Constitution places restrictions on the quartering of soldiers in private homes without the owner's consent, forbidding the practice inpeacetime. The amendment was a response to theQuartering Acts passed by theParliament of Great Britain during the buildup to theAmerican Revolutionary War, which had allowed theBritish Army to lodge soldiers in public buildings.
The Third Amendment was introduced in Congress in 1789 byJames Madison as a part of theUnited States Bill of Rights, in response toAnti-Federalist objections to the new Constitution. Congress proposed the amendment to the states on September 28, 1789, and by December 15, 1791, the necessary three-quarters of the states had ratified it. Secretary of StateThomas Jefferson announced the adoption of the amendment on March 1, 1792.
The amendment is one of the least controversial of the Constitution and is rarely litigated, with criminal justice writerRadley Balko calling it the "runt piglet" of the U.S. Constitution.[1] To date, it has never been the primary basis of a Supreme Court decision,[2][3][4] though it was the basis of theCourt of Appeals for the Second Circuit caseEngblom v. Carey in 1982.
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.[5]
In 1765, theParliament of Great Britain enacted the first of theQuartering Acts,[6] requiring theThirteen Colonies to provide food toBritish Army troops serving in the colonies, and ordering that if their local barracks provided insufficient space, that colonial authorities lodge troops in public buildings such as alehouses, inns, and livery stables. After theBoston Tea Party, the Quartering Act of 1774 was enacted. As one of theIntolerable Acts that pushed the colonies toward revolution, it authorized British troops to be housed wherever necessary, though no troops were ever quartered in inhabited homes.[7] The quartering of troops was cited as one of the colonists' grievances in theUnited States Declaration of Independence.[3]
After several years of comparatively weak government under theArticles of Confederation, aConstitutional Convention in Philadelphia proposed a new constitution on September 17, 1787, featuring a stronger chief executive and other changes.George Mason, a Constitutional Convention delegate and the drafter ofVirginia's Declaration of Rights, proposed that a bill of rights listing and guaranteeingcivil liberties be included. Other delegates—including future Bill of Rights drafterJames Madison—disagreed, arguing that existing state guarantees of civil liberties were sufficient and that any attempt to enumerate individual rights risked implying that other, unnamed rights were unprotected. After a brief debate, Mason's proposal was defeated by a unanimous vote of the state delegations.[8]
For the constitution to be ratified, however, nine of the thirteen states were required to approve it in state conventions. Opposition to ratification ("Anti-Federalism") was partly based on the Constitution's lack of adequate guarantees for civil liberties. Supporters of the Constitution in states where popular sentiment was against ratification (including Virginia, Massachusetts, and New York) successfully proposed that their state conventions both ratify the Constitution and call for the addition of a bill of rights. Several state conventions specifically proposed a provision against the quartering of troops in private homes.[3] At the 1788Virginia Ratifying Convention,Patrick Henry stated, "One of our first complaints, under the former government, was the quartering of troops among us. This was one of the principal reasons for dissolving the connection with Great Britain. Here we may have troops in time of peace. They may be billeted in any manner—to tyrannize, oppress, and crush us."[7]

In the 1st United States Congress, following the state legislatures' request, James Madison proposed twenty constitutional amendments based on state bills of rights and English sources such as theBill of Rights 1689; one of these was a prohibition against quartering troops in private homes. Several revisions to the future Third Amendment were proposed in Congress, which chiefly differed in the way in which peace and war were distinguished (including the possibility of a situation, such as unrest, which was neither peace nor war), and whether the executive or the legislature would have the authority to authorize quartering.[9] However, the amendment ultimately passed Congress almost unchanged and by unanimous vote.[3] Congress reduced Madison's proposed twenty amendments to twelve, and these were submitted to the states for ratification on September 25, 1789.[10]
By the time the Bill of Rights was submitted to the states for ratification, opinions had shifted in both parties. Many Federalists, who had previously opposed a Bill of Rights, now supported the Bill as a means of silencing the Anti-Federalists' most effective criticism. Many Anti-Federalists, in contrast, now opposed it, realizing the Bill's adoption would greatly lessen the chances of a second constitutional convention, which they desired.[11] Anti-Federalists such asRichard Henry Lee also argued that the Bill left the most objectionable portions of the Constitution, such as the federal judiciary and direct taxation, intact.[12]
On November 20, 1789, New Jersey ratified eleven of the twelve amendments, rejectingArticle II, which regulated Congressional pay raises. On December 19 and 22, respectively, Maryland and North Carolina ratified all twelve amendments.[13] On January 19, 25, and 28, 1790, respectively, South Carolina, New Hampshire, and Delaware ratified the Bill, though New Hampshire rejected the amendment on Congressional pay raises, and Delaware rejectedArticle I, which regulated the size of the House.[13] This brought the total of ratifying states to six of the required ten, but the process stalled in other states: Connecticut and Georgia found a Bill of Rights unnecessary and so refused to ratify, while Massachusetts ratified most of the amendments, but failed to send official notice to the Secretary of State that it had done so.[12][a]
In February through June 1790, New York, Pennsylvania, and Rhode Island ratified eleven of the amendments, though all three rejected the amendment on Congressional pay raises. Virginia initially postponed its debate, but after Vermont was admitted to the Union in 1791, the total number of states needed for ratification rose to eleven. Vermont ratified on November 3, 1791, approving all twelve amendments, and Virginia finally followed on December 15, 1791.[12] Secretary of StateThomas Jefferson announced the adoption of the ten successfully ratified amendments on March 1, 1792.[14]

The Third Amendment is among the least cited sections of the U.S. Constitution.[15] In the words ofEncyclopædia Britannica, "as the history of the country progressed with little conflict on American soil, the amendment has had little occasion to be invoked."[16] To date, no major Supreme Court decision has used the amendment as its primary basis.[3][4]
The legal historian Tom W. Bell argued in 1993 that the quartering of American soldiers during theWar of 1812 andAmerican Civil War violated the Third Amendment, but this argument was never presented in court during either war. Following the Civil War, the Army compensated property owners for rent and damages, which may have preempted Third Amendment claims.[17]
The Third Amendment has been invoked in a few instances as helping establish an implicit right to privacy in the Constitution.[18] JusticeWilliam O. Douglas used the amendment along with others in the Bill of Rights as a partial basis for the majority decision inGriswold v. Connecticut (1965),[19] which cited the Third Amendment as implying a belief that an individual's home should be free from agents of the state.[18]
In one of the seven opinions inYoungstown Sheet & Tube Co. v. Sawyer (1952), JusticeRobert H. Jackson cited the Third Amendment as providing evidence of theFramers' intent to constrain executive power even during wartime:[18]
[t]hat military powers of the Commander in Chief were not to supersede representative government of internal affairs seems obvious from the Constitution and from elementary American history. Time out of mind, and even now in many parts of the world, a military commander can seize private housing to shelter his troops. Not so, however, in the United States, for the Third Amendment says ... [E]ven in war time, his seizure of needed military housing must be authorized by Congress.[20]
One of the few times afederal court was asked to invalidate a law or action on Third Amendment grounds was inEngblom v. Carey (1982).[21] In 1979, prison officials in New York organized a strike; they were evicted from their prison facility residences, which were reassigned to members of theNational Guard who had temporarily taken their place as prison guards. TheUnited States Court of Appeals for the Second Circuit ruled: (1) that the termowner in the Third Amendment includes tenants (paralleling similar cases regarding theFourth Amendment, governing search and seizure), (2) National Guard troops are "soldiers" for purposes of the Third Amendment, and (3) that the Third Amendment isincorporated (applies to the states) by virtue of theFourteenth Amendment.[22] The case was remanded to the district court, which dismissed it on the grounds that state officials could not have been aware of this interpretation.[23]
In the most recent Third Amendment decision handed down by a federal court, on February 2, 2015, theUnited States District Court for the District of Nevada held inMitchell v. City of Henderson that the Third Amendment does not apply to intrusions by municipal police officers as they are not soldiers.[24] For his claims under the Third Amendment, Mitchell had alleged that the police used his house as a lookout point.[25]
In an earlier case,United States v. Valenzuela (1951),[26] the defendant asked that a federal rent-control law be struck down because it was "the incubator and hatchery of swarms of bureaucrats to be quartered as storm troopers upon the people in violation of Amendment III of the United States Constitution."[27] The court declined his request. Later, inJones v. United States Secretary of Defense (1972),[28] Army reservists unsuccessfully cited the Third Amendment as justification for refusing to march in a parade. Similar arguments in a variety of contexts have been denied in other cases.[29]
