Yale law professor Ian Ayres works through Feld v. Henry S. Levy & Sons as his case study on the duty of good faith in contract performance, part of his American Contract Law course. The dispute turns on a bakery's obligation to keep producing whole wheat bread for a buyer under an output contract, and Ayres uses it to explain how courts read good faith into performance even when a contract's literal terms would allow a party to walk away. He walks through the court's reasoning step by step, connecting the case to the broader doctrine of good faith that runs through Article 2 of the UCC. The lecture is a short segment from Ayres' recorded Coursera course, later released publicly on YouTube, and assumes some familiarity with the surrounding unit on contract performance.
