Rule 68.03 - Effect of Unaccepted Offer(a) Unaccepted Offer Not Admissible. Evidence of an unaccepted offer is not admissible, except in a proceeding to determine costs and disbursements.(b) Effect of Offer on Recovery of Costs. An unaccepted offer affects the parties' obligations and entitlements regarding costs and disbursements as follows: (1) If the offeror is a defendant, and the defendant-offeror prevails or the relief awarded to the plaintiff-offeree is less favorable than the offer, the plaintiff-offeree must pay the defendant-offeror's costs and disbursements incurred in the defense of the action after service of the offer, and the plaintiff-offeree shall not recover its costs and disbursements incurred after service of the offer, provided that applicable attorney fees available to the plaintiff-offeree shall not be affected by this provision.(2) If the offeror is a plaintiff, and the relief awarded is less favorable to the defendant-offeree than the offer, the defendant-offeree must pay, in addition to the costs and disbursements to which the plaintiff-offeror is entitled under Rule 54.04, an amount equal to the plaintiff-offeror's costs and disbursements incurred after service of the offer. Applicable attorney fees available to the plaintiff-offeror shall not be affected by this provision.(3) If the court determines that the obligations imposed under this rule as a result of a party's failure to accept an offer would impose undue hardship or otherwise be inequitable, the court may reduce the amount of the obligations to eliminate the undue hardship or inequity.(c) Measuring Result Compared to Offer. To determine for purposes of this rule if the relief awarded is less favorable to the offeree than the offer: (1) a damages-only offer is compared with the amount of damages awarded to the plaintiff; and(2) a total-obligation offer is compared with the amount of damages awarded to the plaintiff, plus applicable prejudgment interest, the plaintiff's taxable costs and disbursements, and applicable attorney fees, all as accrued to the date of the offer.
