Section 270.50 - Trial jury; viewing of premises1. When the court is of the opinion that a viewing or observation by the jury of the premises or place where an offense on trial was allegedly committed, or of any other premises or place involved in the case, will be helpful to the jury in determining any material factual issue, it may in its discretion, at any time before the commencement of the summations, order that the jury be conducted to such premises or place for such purpose in accordance with the provisions of this section.2. In such case, the jury must be kept together throughout under the supervision of an appropriate public servant or servants appointed by the court, and the court itself must be present throughout. The prosecutor, the defendant and counsel for the defendant may as a matter of right be present throughout, but such right may be waived.3. The purpose of such an inspection is solely to permit visual observation by the jury of the premises or place in question, and neither the court, the parties, counsel nor the jurors may engage in discussion or argumentation concerning the significance or implications of anything under observation or concerning any issue in the case.N.Y.
