The least litigated amendment in the Constitution helped build the right to privacy.

No soldier has been quartered in an American home in living memory. The Third Amendment has produced almost no case law. Engblom v. Carey (2d Cir. 1982) is the rare federal appellate decision to treat it seriously, and it arose from a prison guards’ strike, not an army.

So why does a dead letter keep showing up in the most consequential privacy litigation of the last sixty years?

Because of what it signals. In Griswold v. Connecticut (1965), Justice Douglas assembled a right of privacy from the penumbras of several guarantees, and the Third Amendment was one of them. Its presence in that list matters: it is textual proof that the founders treated the home as a space the government does not simply occupy, even in wartime, even when it would be convenient.

This episode runs Authorize, Constrain, Gap on a provision with almost nothing to constrain. Authorize: no quartering in peacetime without consent. Constrain: virtually nothing, because the conduct stopped. Gap: an amendment with no modern enforcement record still does structural work, and that raises a real question about how we measure a provision’s importance. Case count is a poor proxy. A right nobody violates may be the most successful right in the document.

Almost no litigation has ever turned on it directly, which is exactly what makes it useful. It is the clearest textual evidence that the framers treated the home as protected ground against the government, and that premise does real work in later privacy reasoning even where the clause itself is never cited. The episode argues that a clause can matter constitutionally without ever being litigated, an unusual claim worth the time.
