In a perfect world, the evidence in a lawsuit would be so obviously convincing in favor of one party or the other that a jury would be able to reach a quick and unanimous verdict. In the real world, however, a case in which the evidence is so clearly in one party’s favor usually gets settled out of court.
As for the rest, the question sometimes arises as to what a judge should do after the jury has said they are deadlocked. In the landmark case of Allen v. United States, 164 U.S. 492 (1896), the nation’s highest court approved, at least for the federal courts, a jury instruction advising jurors to listen to one another with a disposition towards being convinced of each other’s arguments.
Recently, the South Carolina Court of Appeals was called upon to consider whether an Allen charge was acceptable in a particular South Carolina state court case.
