MODERN MACHINERY, Plaintiff and Appellant,
v.
FLATHEAD COUNTY, Defendant and Respondent.
No. 82-265.
Supreme Court of Montana.
Submitted on Briefs November 24, 1982.
Decided December 29, 1982.
*208 James D. Moore, Kalispell, for plaintiff and appellant.
Gary R. Christiansen, Ted O. Lympus, County Atty., Kalispell, for defendant and respondent.
HARRISON, Justice.
Plaintiff brought this action for breach of contract in the Eleventh Judicial District in Flathead County. A jury trial commenced in Kalispell, Montana, on February 24, 1982. On February 26, 1982, the jury returned a verdict awarding plaintiff $10,000. Plaintiff and defendant appeal from the judgment entered upon the jury's verdict.
On or about July 30, 1979, the Flathead County commissioners issued a call for bids for the purchase of a jaw-type rock crusher to be used by the Flathead County road department. The commissioners received three bids in response to the call, one from plaintiff in the amount of $305,725 and two from another Kalispell distributor, Westmont; one for $201,193 and the other for $200,870. On August 22, 1979, the day the bids were opened, the commissioners voted to take the bids under advisement pending recommendation of the county road department. Representatives from the road department and Commissioner Frank Guay then flew to Cedar Rapids, Iowa, with plaintiff's agent, Jim Fox, to view plaintiff's crusher. Commissioner Guay and the representatives from the road department were impressed with features contained on plaintiff's crusher which were not available on Westmont's models.
On September 14, 1979, the commissioners met with members of the road department and Jim Fox to discuss the crusher bids. The road department recommended that the commissioners purchase plaintiff's crusher. Commissioner Guay then made a motion to accept the road department's recommendation. The motion was seconded by Commissioner Joan Deist. The motion was recorded in the minutes of the meeting as follows:
"Motion to Guay to accept the Road Department's recommendation to purchase gravel crusher from Modern Machinery for $305,725. The only other bid being received having been for used power plant generator contained in a second unit not attached to the crusher itself, thereby creating operational problems. Motion seconded by Joan A. Deist, motion carried. Note: Mel Wollan votes no on crusher bid as the lower bid for a jaw crusher was very adequate and a savings of $100,000."
Everyone in attendance at the meeting who testified at the trial felt that the county was going to eventually purchase plaintiff's crusher. On September 17, the following Monday, an attorney representing Westmont delivered a letter to commissioner Frank Guay which requested that the award to plaintiff be vacated or he would seek to enforce Westmont's rights in the matter by whatever means permitted by law. Guay then called Jim Fox in Missoula and told him if the crusher had been ordered from the factory, to have the order stopped.
On Wednesday, Fox and another representative for plaintiff, Larry Exe, met Guay in Helena, Montana, to discuss the crusher. Guay testified at trial that he again told Fox and Exe to stop order on the crusher if it had, in fact, been ordered. Fox and Exe testified that the meeting in Helena was mainly to discuss the political ramifications to Guay should the sale be completed. After the meeting in Helena, Exe called the factory to see how far they had *209 progressed on the order. Exe told the factory to let him know how much expense would be incurred if plaintiff was to stop order on the crusher at that time. That was the last contact plaintiff had with the factory concerning a stop order on the crusher.
Fox, Guay and Exe then met with Assistant County Attorney, Charles Kuether, at the Flathead County commissioner's office. Again, Guay told plaintiff's representatives not to order the crusher. Guay stated that the bid award was not final until the clerk and recorder's office issued a letter accepting plaintiff's bid and rejecting all other bids. A second meeting with Kuether followed attended by Fox, Exe, Guay and plaintiff's attorney. Again, Guay stated the bid award was not final until the clerk and recorder's office issued notice of the successful bid. Plaintiff's counsel requested a letter directing plaintiff to either order or stop order on the crusher. Guay refused to draft such a letter stating that since the commissioners had not formally ordered the crusher it was not necessary to rescind an order. That was the last meeting between plaintiff and the commissioner's office.
On November 11, 1979, plaintiff tendered the crusher to Flathead County pursuant to the statement in the call for bids that delivery must be within forty-five days from date of order. The county refused to accept delivery of the machine. On November 20, 1979, the commissioners met and issued a letter to plaintiff stating they had decided to reject all bids received in response to its call for bids on the rock crusher. Plaintiff subsequently transported the crusher to Tempe, Arizona, where it was finally sold. On December 11, 1979, plaintiff filed a complaint in the District Court of the Eleventh Judicial District, in and for the County of Flathead, against Flathead County alleging breach of contract. After a jury trial commencing February 24, 1982, the jury returned a verdict in favor of plaintiff assessing damages in the amount of $10,000. Plaintiff then filed this appeal and defendant cross-appeals.
The substance of the appeals is as follows:
1. Whether there was a valid contract.
2. Whether the jury was properly instructed on the measure of damages.
3. Whether the jury verdict was supported by substantial credible evidence.
The essential elements of a contract are: parties capable of contracting, consent, a lawful objective, and consideration. Section 28-2-102, MCA; Keil v. Glacier Park Inc. (1980), Mont., 614 P.2d 502, 505, 37 St.Rep. 1151. In this case the issue of whether or not there was a contract goes to the requirement of consent. There is consent to contract when there has been an offer and acceptance of the offer.
Here, plaintiff's written bid issued in response to Flathead County's call for bids constitutes an offer. However, a written bid has consistently been construed as nothing more than an offer to perform labor or supply materials, and the offer does not ripen into a contract until accepted by the offeree. Carriger v. Ballenger (1981), Mont., 628 P.2d 1106, 1108, 38 St.Rep. 864. Thus, we must determine whether the Flathead County commissioners accepted plaintiff's offer thereby creating a contract.
After the bids were opened, the commissioners voted to take the bids under advisement pending a recommendation by the Flathead County road department. On September 14, 1979, the commissioners met with members of the road department and Jim Fox to discuss the bids. At that meeting the members of the road department recommended that the commissioners purchase plaintiff's crusher. A motion was made, seconded and recorded: "Motion by Guay to accept the road department's recommendation to purchase gravel crusher from Modern Machinery for $305,725.00." (Emphasis added.)
Commissioner Joan Deist testified that the commissioners normally make one of three motions upon bids received in response to a call for bids; motion to accept; motion to deny; or motion to take under advisement. Initially, the commissioners *210 took the crusher bids under advisement pending recommendation of the road department. On September 14, the road department recommended that the commissioners purchase plaintiff's crusher. Commissioner Guay moved to accept the road department's recommendation, the motion was seconded and duly recorded in the minutes of the meeting. The third commissioner later noted a no vote on the minutes as he wasn't in attendance at the September 14 meeting.
Flathead County argues there was not acceptance as there was no notice of bid award issued by the clerk and recorder's office. However, everyone in attendance at the meeting, including the commissioners, testified that they thought the commissioners were going to buy plaintiff's crusher. We find there was acceptance on the part of Flathead County when the commissioners accepted and made minutes reflecting the acceptance, and plaintiff was only fulfilling its obligation on the contract by ordering and delivering the crusher. There is no statutory provision for the procedure argued by the county.
Flathead County further argues there was no writing which satisfies the statute of frauds, section 30-2-201, MCA. As stated above, this Court has previously held a written bid can ripen into a contract if accepted by the offeree. Carriger v. Ballenger, supra. Here, we have found the written bid was accepted by Commissioner Guay's motion which was seconded by Commissioner Deist and recorded in the minutes of the September 14 meeting. Thus, there was a valid contract, not barred by the statute of frauds.
The next issue is whether the jury was properly instructed on the measure of damages. First, plaintiff argues the giving of court's instruction No. 7 was in error. The instruction states:
"If you find that the Plaintiff is entitled to damages, you may award any of the following: 1) Lost net profits; 2) Incidental damages such as expenses incurred in the transportation of goods after the buyer's breach."
The measure of damages when a buyer wrongfully rejects or revokes acceptance of goods is governed by the Uniform Commercial Code. Section 30-2-703, MCA, states: "Where the buyer wrongfully rejects or revokes acceptance of goods ... the aggrieved seller may: (d) resell and recover damages as hereinafter provided (30-2-706); (e) recover damages for nonacceptance (30-2-708) ..." Pursuant to section 30-2-706, MCA: "the seller may recover the difference between the resale price and the contract price together with any incidental damages ... less expenses saved in consequence of the buyer's breach." Pursuant to section 30-2-708, MCA: "the measure of damages for nonacceptance or repudiation by the buyer is the difference between the market price at the time and place for tender and the unpaid contract price together with any incidental damages ... less expenses saved in consequence of the buyer's breach." or "If the measure of damages provided in subsection (2) is inadequate to put the seller in as good a position as performance would have done then the measure of damages is the profit ... which the seller would have made from full performance by the buyer together with any incidental damages ..., due allowance for costs reasonably incurred and due credit for payments or proceeds of resale."
We find court's instruction no. 7 was not a correct statement of the law as stated by the U.C.C. The possible measures of damages under the U.C.C. are not stated in permissive language, but rather, are mandatory and specifically state the amount of recoverable damage depending upon the remedy seller has pursued. The District Court's use of the words "may award any of the following" in instruction no. 7 implied to the jury that they were not required by law to award specific damages. Thus, the giving of the District Court's instruction no. 7 was in error as being in contradiction of the U.C.C.
Plaintiff also claims the giving of the following instruction was in error:

*211 "A party who alleges that it has been damaged by the breach of contract by another party is bound to exercise reasonable care and diligence to avoid loss and to minimize its damage. A party may not recover for losses which could have been prevented by reasonable efforts on its part."
We find the giving of this instruction was in error. In this case a method of mitigating damages is addressed by section 30-2-704(2), MCA. The section states:
"Where the goods are unfinished an aggrieved seller may in the exercise of reasonable commercial judgment for the purposes of avoiding loss and of effective realization either complete the manufacture and wholly identify the goods to the contract or cease manufacture and resell for scrap or salvage value or proceed in any reasonable manner."
This section is better understood by looking to the Official Comment to section 30-2-704(2), MCA:
"Under this Chapter the seller is given express power to complete manufacture or procurement of goods for the contract unless the exercise of reasonable commercial judgment as to the facts as they appear at the time he learns of the breach makes it clear that such action will result in a material increase in damages. The burden is upon the buyer to show the commercially unreasonable nature of the seller's action in completing manufacture."
Here, Commissioner Guay expressed concern about the contract at an early date, but, the board of commissioners refused to repudiate the contract. The county has power to contract, and its contracts are the contracts of its board of county commissioners, not of the individual members thereof. Bennett v. Petroleum County et al. (1930), 87 Mont. 436, 447, 288 P. 1018, 1020. Commissioner Guay did not have the authority to individually revoke the contract and when plaintiff asked that the board take some action it refused. Thus, plaintiff was acting in a commercially reasonable manner to fulfill its obligation under the contract. If plaintiff had not delivered the crusher within forty-five days, it would have breached the contract and exposed itself to legal liability. Had the board taken some action at an early date, plaintiff could have mitigated its damages under section 30-2-704, MCA. The District Court's instruction unfairly placed the entire burden to mitigate damages upon plaintiff whereas the comments to section 30-2-704, MCA, state: "the burden is upon the buyer [Flathead County] to show the commercially unreasonable nature of the seller's action in completing manufacture." Thus, the giving of the Court's instruction was in error.
The last issue is whether the jury verdict was supported by substantial credible evidence. As stated above, the measure of damages is governed by section 30-2-706, MCA, and section 30-2-708, MCA. Under section 30-2-706, MCA, the damages would be the contract price ($305,725) plus incidental damages less the resale price ($186,499.86) and expenses saved in consequence of the buyer's breach. Under section 30-2-708(2) the damages would be plaintiff's anticipated profit ($78,879.56) plus incidental damages less credit for payments made or proceeds of resale. Using either section in this instance the record shows plaintiff's damages were far in excess of $10,000 and there is no substantial credible evidence which can support the jury verdict.
We affirm the case as to county's liability and judgment is reversed and the case is remanded to the District Court for a hearing on damages by following the applicable statutes.
HASWELL, C.J., and SHEA, SHEEHY and WEBER, JJ., concur.
