Can a jury in a personal injury case be found to have given incorrect jury instructions?

Federal Rule of Civil Procedure 51 provides that "[n]o party may assign as error the giving or the failure to give an instruction unless that party objects thereto before the jury retires to consider its verdict, stating distinctly the matter objected to and the grounds of the objection." This court interprets Rule 51 strictly. Glover v. Bic Corp., 987 F.2d 1410, 1418 (9th Cir. 1993). In civil cases, we will not reverse a jury verdict because of improper jury instructions in the absence of a proper objection, even if the instructions given were plain error. Id.
