ARTICLE VII.
JURY TRIAL IN COMMON LAW SUITS.
In suits at common law,[1] where the amount 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 common law.[2]
[1] The meaning of this expression is difficult of explanation, but it covers most ordinary lawsuits. From the fact that a jury in criminal cases has already been guaranteed (III., 2, 3, and Am. VI.), it may be assumed that this provision is intended to cover civil suits.
[2] Among the "rules of common law" are these: 1. All suits are tried before a judge and a jury, the jury determining the facts in the case and the judge applying the law. 2. The facts tried by a jury can be re-examined only by means of a new trial before the same court or one of the same jurisdiction.
The purpose of this provision is to preserve the jury trial as a real defense against governmental oppression. In the Supreme Court there is no jury; the trials are by the court. If questions of fact could be reviewed or re-examined by such a court on appeal the protection now given by the jury would be nullified.
