Case Brief Summary & Legal Analysis

General Brief
3 min read

tl;dr: A buyer extended a delivery deadline for a farmer who failed to deliver soybeans. The court found the extensions, made in a rising market, were proposed in bad faith because the buyer knew the farmer could not perform, invalidating the modification and fixing damages at the original breach date.

Legal Significance: A contract modification under the UCC, even if accepted through a course of performance, is invalid if the proposing party acts in bad faith by seeking to extend the contract in a rising market to compound, rather than mitigate, the other party’s damages.

Case Facts & Court Holding

Key Facts & Case Background

Plaintiff Ralston Purina Company (buyer) contracted with defendant F. R. McNabb (seller), a farmer, for the November 1972 delivery of 8,000 bushels of soybeans. Due to severe weather and flooding, McNabb failed to deliver the full quantity by the November 30 deadline. Ralston Purina sent McNabb monthly letters extending the delivery deadline for December, January, and February. During this extension period, McNabb continued to make partial deliveries, for which he was paid the original contract price, despite a steadily rising market price for soybeans. McNabb ultimately failed to deliver 3,771 bushels. Ralston Purina sued, seeking damages calculated based on the market price in March 1973. McNabb argued the extensions were invalid and damages should be calculated as of the original November 30 breach date. A jury found that as of November 30, Ralston Purina knew or should have known that McNabb would be unable to complete his contract.
