Extends the right to a jury trial to civil (non-criminal) lawsuits above a certain dollar value, and limits how much a court can revisit a jury's findings of fact on appeal. Unlike most of the Bill of Rights, this one has never been applied to state courts.
In Suits at common law, where the value in controversy shall exceed twenty dollars, the right of trial by jury shall be preserved, and no fact tried by a jury, shall be otherwise re-examined in any Court of the United States, than according to the rules of the common law.
