1:7-2. Objections
For the purpose of reserving questions for review or appeal relating to rulings or orders of the court or instructions to the jury, a party, at the time the ruling or order is made or sought, shall make known to the court specifically the action which the party desires the court to take or the party's objection to the action taken and the grounds therefor. Except as otherwise provided by R. 1:7-5 and R. 2:10-2 (plain error), no party may urge as error any portion of the charge to the jury or omissions therefrom unless objections are made thereto before the jury retires to consider its verdict, but opportunity shall be given to make the objection in open court, in the absence of the jury. A party shall only be prejudiced by the absence of an objection if there was an opportunity to object to a ruling, order or charge.
