# Third Amendment (Ratified December 15, 1791) > 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. The Third Amendment to the United States Constitution — ratified December 15, 1791 as part of the [[Bill of Rights]] — prohibits the government from housing soldiers in private homes without the owner's consent during peacetime, and permits it during wartime only as prescribed by law. It is the least-litigated provision in the [[Constitution]], having produced exactly one significant federal appellate decision in over two centuries. Its apparent irrelevance is itself historically instructive: the colonial grievance that burned hottest became constitutionally moot, while the [[Second Amendment]]'s militia provision — rooted in the same anti-standing-army ideology — became the most politically explosive clause in American law. ## Colonial Origins The Amendment responded to a specific and deeply resented British practice. The Quartering Acts of 1765 and 1774 required American colonists to house and provision British troops in private homes and buildings. The 1774 version — one of the "Intolerable Acts" — allowed quartering in occupied dwellings over the owner's objection. For colonists, forced quartering was not merely an economic burden but a visceral violation of domestic sovereignty: armed agents of the state living inside your home, eating your food, surveilling your family. The Declaration of Independence listed "quartering large bodies of armed troops among us" as a grievance against George III. The deeper ideological substrate was the [[Revolutionary War]]-era fear of standing armies — the conviction, inherited from English Whig thought and the [[Anti-Federalist Papers]] tradition, that a permanent professional military was the instrument through which republics became tyrannies. Quartering was the point where standing-army power physically invaded private life. ## The One Case: *Engblom v. Carey* (1982) The Second Circuit's *Engblom v. Carey* decision is the Third Amendment's sole moment in the appellate sun. During a 1979 New York prison guard strike, the state housed [[National Guard]] troops in guards' residential quarters at correctional facilities. The court made two significant holdings: first, the Third Amendment's protections extend to tenants and not merely property owners (the "Owner" language covers possessory interests); second, National Guard members activated by a governor qualify as "soldiers" under the Amendment. The case was ultimately decided on qualified immunity grounds and the guards lost on the merits, but the doctrinal framework stands. ## The Privacy Penumbra The Third Amendment's most consequential legal afterlife has nothing to do with quartering. In *Griswold v. Connecticut* (1965), Justice William O. Douglas's majority opinion identified a constitutional "right to privacy" emanating from the "penumbras" of several amendments — and the Third was among them. The logic: an amendment protecting the home from government military intrusion necessarily implies a broader principle of domestic privacy. The Third thus became a textual anchor for the unenumerated privacy right that later supported *[[Roe v. Wade]]* (1973) and the broader substantive-due-process framework. This penumbral role makes the Third Amendment a flashpoint in the [[Originalism]] debate. Strict textualists reject penumbral reasoning entirely — the Amendment prohibits quartering, full stop, and extracting a general privacy principle from it is precisely the kind of interpretive overreach they oppose. But the Amendment's existence poses an awkward question for originalists who also claim the [[Constitution]] enumerates all the rights it protects: why did the Founders feel compelled to prohibit something so specific unless they understood the document as illustrative rather than exhaustive? This is the same tension the [[Ninth Amendment]] addresses directly. ## The Standing-Army Irony The Third Amendment, the [[Second Amendment]], and the broader Anti-Federalist anxiety about military power form a coherent ideological package. The Founders feared standing armies because they associated them with quartering, martial law, and the suppression of civilian governance. The Third Amendment addressed the quartering problem. The Second Amendment addressed the standing-army problem by constitutionalizing the militia as an alternative to professional forces. The historical irony is stark: the United States now maintains the largest permanent military establishment in human history, with over 750 overseas bases, a $900+ billion annual defense budget, and a militarized domestic police force — and the constitutional provision that addressed quartering became irrelevant while the provision that addressed militias became an individual right to firearms ownership entirely detached from its anti-standing-army origins. The Founders' actual concern — concentrated military power threatening civilian liberty — went unaddressed by either amendment. ## Why It Matters for the KB **Privacy-rights genealogy.** The Third Amendment is part of the constitutional infrastructure that produced the privacy right — the doctrinal pathway from *Griswold* through *Roe* to *[[Dobbs v. Jackson Women's Health Organization]]* runs through the penumbral argument that included the Third. Understanding how conservatives dismantle privacy rights requires understanding how they were constructed. **The standing-army through-line.** The Anti-Federalist fear that produced this Amendment is the same fear that produced the [[Second Amendment]]. Tracking how the conservative movement adopted the Second Amendment while ignoring the Third — and while enthusiastically funding the permanent military establishment the Founders feared — reveals the selectivity of "originalist" constitutional interpretation. **Constitutional irrelevance as data point.** The Third Amendment demonstrates that constitutional provisions can become dead letters not through repeal or hostile interpretation but through historical obsolescence. The quartering grievance vanished because the conditions producing it vanished. This raises the question of whether other provisions — designed for an eighteenth-century agrarian republic — remain adequate to twenty-first-century governance problems. ## See Also - [[Bill of Rights]] — the first ten amendments - [[Constitution]] — the foundational document - [[Second Amendment]] — companion amendment rooted in anti-standing-army ideology - [[Fourth Amendment]] — companion privacy-protecting amendment - [[Fifth Amendment]] — companion due-process amendment - [[Ninth Amendment]] — the amendment addressing unenumerated rights - [[Anti-Federalist Papers]] — the ideological tradition driving the quartering prohibition - [[Revolutionary War]] — the conflict that produced the quartering grievance - [[Originalism]] — the interpretive method that rejects penumbral reasoning - [[Alexander Hamilton]] — Federalist defender of standing armies against Anti-Federalist opposition
