CONSIDERED ON BRIEFS APRIL 28, 2025 OPINION FILED 07/09/25 #30783

JENSEN, Chief Justice

[¶1.] Calvin Berwald operated a dairy farm as Sokota Dairy, near Alpena,

South Dakota. He filed this action alleging that Stan’s, Inc. (Stan’s), a local feed

mill, breached an agreement for Berwald to purchase soybean meal by prematurely

cancelling it. Berwald also alleged that Stan’s breached the implied warranties of

merchantability and fitness for a particular purpose arising from his separate

purchase of calf starter, claiming that contaminated calf starter caused the death of

more than 200 of his cattle. The circuit court granted Stan’s motion for summary

judgment on the breach of contract claim based upon accord and satisfaction.

Following trial, a jury found that Stan’s breached the warranty of fitness for a

particular purpose but that no damages were caused by the breach. Berwald

appeals, arguing the circuit court erred in granting summary judgment on the

breach of contract claim and in denying his motion for a new trial.

Factual and Procedural History

[¶2.] In January 2012, Berwald contracted with Stan’s to purchase 400 tons

of soybean meal at $319 per ton for delivery between February 1 and September 30

of that year (the commodity contract). Soybean meal was a primary component of

the feed mixtures Berwald used to feed his dairy herd. Berwald would periodically

order a custom dry feed composed of the purchased soybean meal mixed with other

ingredients from Stan’s.

[¶3.] In April 2012, Berwald purchased a customized calf starter mixture

from Stan’s. On the morning of May 3, three of Berwald’s calves were found dead.

Berwald contacted Dr. Hubbert, a veterinarian, to investigate the death of the

-1- #30783

calves. Dr. Hubbert conducted an autopsy on one of the calves and observed

evidence of possible monensin toxicity.1 Dr. Hubbert instructed Berwald to send

the remains of the two other calves and a sample of the feed to the animal science

department at South Dakota State University for further investigation.

[¶4.] On June 7, Mike Kopfmann, the general manager at Stan’s, called

Berwald to inform him that the company would be buying back the commodity

contract due to late payments on the purchased soybean meal. The written

commodity contract did not include any payment terms. Kopfmann testified that

Berwald initially had a credit line with Stan’s, but claimed there were multiple

instances of “slow pay” that required Stan’s to hold Berwald’s checks for several

days until his account had sufficient funds for the checks to clear. Kopfmann

explained that Stan’s gave Berwald the opportunity to continue under the

commodity contract if he started paying in cash upon delivery of the soybean meal.

When Berwald failed to meet this condition, Stan’s made the decision to cancel the

contract. Kopfmann also testified that when he spoke with Berwald about this

decision, Berwald communicated, for the first time, his belief that Stan’s calf starter

was killing his calves.

[¶5.] On June 11, Stan’s sent a letter to Berwald notifying him that it would

be cancelling the commodity contract on June 15 due to “insufficient credit

performance.” Because the price of soybean meal had increased since January,

1. Throughout the record and transcripts, monensin is referred to under its brand name, Rumensin. Monensin is an ionophore antibiotic used to promote growth and prevent disease but excessive amounts from accidental contamination or mixing errors in feed can be fatal to cattle. -2- #30783

Stan’s offered to buy out the contract by paying the difference between the

contracted price and the increased price reflected on the Chicago Board of Trade

(CBOT). The letter explained that the undelivered balance of 274.56 tons would be

priced based on the CBOT July soybean meal futures price, less $45 per ton.2 These

proceeds would be applied to the $5,982.75 Berwald owed on accounts receivable,

and a payment would be issued to Berwald for the remaining amount.

[¶6.] Berwald responded in a letter sent by his attorney on June 14,

expressing Berwald’s concern that cancelling the commodity contact would result in

significant losses to him. The letter indicated that Berwald believed he was up to

date on his payments to Stan’s and that he had not received a bill for the $5,982.75

referred to in the June 11 letter. Berwald disputed that his payment history

showed any type of insufficient credit performance and requested that Stan’s refrain

from canceling the commodity contract until the parties had a chance to discuss

these issues. The letter also requested a copy of the commodity contract and

clarification on the credit requirements Berwald allegedly failed to meet.

[¶7.] The following day, Stan’s cancelled the commodity contract with

Berwald and sold the corresponding futures contract for the remaining 275.56 tons

at the close of trading on the CBOT. On June 18, Stan’s sent Berwald a letter

confirming the cancellation. The letter included Stan’s calculation of the payment

due Berwald and a check payable to Sokota Dairy for that amount. Stan’s

calculation began with the July soybean meal futures price of $411 per ton,

2. Stan’s June 18 letter explained that the $45 reduction was the “local basis” reduction. The “local basis” is the difference between the local cash price for the commodity on a certain date and the CBOT futures price. -3- #30783

subtracted the $45 local basis to arrive at $366, and then compared that figure with

the January contract price of $319 per ton. The $47 per ton difference was

multiplied by the remaining 274.56 tons of undelivered soybean meal, for a total of

$12,904.32. Stan’s then applied these proceeds towards the $5,982.75 it claimed

Berwald owed for delivered soybean meal, leaving an excess of $6,921.57 due to

Berwald. The letter stated: “This payment will satisfy all obligations between

Stan’s, Inc. and Sokota Dairy.” Berwald endorsed the check on behalf of Sokota

Dairy and negotiated the check on June 20.

[¶8.] On August 17, Berwald’s attorney sent a letter to Stan’s asserting that

the termination of the commodity contract was unwarranted and requesting that it

be reinstated or that a new contract be drawn up with identical terms. The letter

noted that “no one disputes that the Berwald calves were poisoned by feed

containing Rumensin far in excess of ranges acceptable even to adult cattle.” The

letter further alleged that it appeared from the timeline of events that shortly after

Berwald reported to Stan’s that his calves were dying, Stan’s cancelled the

commodity contract due to insufficient credit performance, yet none of the invoices
