Full Text of Rule 39
Plain-English Summary
Not every case ends up in front of a jury. Rule 39 covers what happens to the facts of a case once Rule 38 has sorted out whether a jury applies. If the facts are not sent to a jury, the judge decides them instead.
Even in cases where a jury trial is not a right, the court still has options. On its own initiative, or if a party asks, the court may bring in an advisory jury to help work through the facts. If both parties agree, the court can also order a full jury trial, and that jury’s verdict counts the same as if the jury trial had been required from the start.
The rule also addresses how a trial opens. After the jury is chosen and sworn in, and before the lawyers give their opening statements, the judge may give the jury some preliminary guidance. That can include explaining what each side claims, describing the burden of proof, explaining what “preponderance of the evidence” means, and covering other basic legal rules that help the jury follow the trial.
Once evidence starts, the plaintiff gets the first opening statement. Other parties can either give their own opening statement right away or wait until it is their turn to present their case. No one is forced to give an opening statement, and one party skipping it does not affect any other party’s right to make one.
Frequently Asked Questions
If a case does not qualify for a jury trial, who decides the facts?
The judge does. Rule 39 states that issues of fact not submitted to a jury under Rule 38 are tried by the court.
Can a judge use a jury even when the case does not require one?
Yes. The court can call in an advisory jury on its own or by motion, and if both parties agree, the court can order a binding jury trial even though one was not required.
Does the judge talk to the jury before the lawyers make their opening statements?
The judge may give preliminary instructions after the jury is sworn in and before opening statements, covering things like the parties’ claims, the burden of proof, and other basic rules to help the jury follow the trial.
Does the plaintiff always give the first opening statement?
Yes, the plaintiff may open first. Other parties can then give their opening statement right away or wait and give it when they begin presenting their own case.
Do all parties have to give an opening statement?
No. Any party can waive an opening statement, and doing so does not take away another party’s right to make one.
