Idaho Code § 19-2133: Retirement of jury — Oath of bailiff.

After hearing the charge, the jury may either decide in court or may retire for deliberation. If they do not agree without retiring, an officer must be sworn to keep them together in some private and convenient place, and not permit any person to speak or communicate with them, nor to do so himself, unless by order of the court, or to ask them whether they have agreed upon a verdict, and to return them into court when they have so agreed, or when ordered by the court.
