Rule 31. Jury Verdict
(a)
Return. The jury must return its verdict to a judge in open court. The verdict must be unanimous.
(b)
Partial Verdicts, Mistrial, and Retrial.
(1)
Multiple Defendants. If there are multiple defendants, the jury may return a verdict at any time during its deliberations as to any defendant about whom it has agreed.
(d)
Jury Poll. After a verdict is returned but before the jury is discharged, the court must on a party’s request, or may on its own, poll the jurors individually. If the poll reveals a lack of unanimity, the court may direct the jury to deliberate further or may declare a mistrial and discharge the jury.
