THE AI-ASSISTED CRITIQUE
The court’s reliance on implied contract to establish a right of return is analytically sound but procedurally precarious. By inferring a course of dealing from prior conduct and correspondence, the decision correctly applies the principle that parties’ consistent practices can modify or supplement written agreements. However, the opinion falters in its factual analysis by dismissing the defendant’s testimony regarding notice of the final return shipment as not “satisfactorily established,” despite acknowledging a pattern of accepted returns. This creates an inconsistency: if a course of dealing was sufficiently established to bind the plaintiff to the practice of accepting returns, it is logically tenuous to then impose a heightened, near-contractual standard for notice of a specific instance within that very practice. The court effectively enforces a custom it helped to define, yet penalizes the defendant for not providing explicit, formal notice that the custom itself did not historically require.

The decision’s treatment of good faith and the plaintiff’s acquiescence is its strongest element, grounded in equitable principles like estoppel in pais. The court rightly notes that the plaintiff, by repeatedly accepting returns and issuing credits without protest, confirmed the defendant’s reasonable belief in her right to reject unsatisfactory goods. The plaintiff’s letters, expressing hope for approval and aiming to “save us other returns,” objectively signaled an ongoing, conditional sales arrangement rather than a series of final, irrevocable sales. This analysis properly prevents a party from selectively enforcing terms; having benefited from the relationship structured by mutual tolerance of returns, the plaintiff cannot suddenly insist on strict, non-returnable sale terms for a disputed shipment without clear, prior communication terminating the established mode of operation.

Ultimately, the ruling is defensible in outcome but reveals a critical flaw in judicial fact-finding regarding the final shipment. The court’s “strong inclination” to doubt the defendant’s testimony about informing the plaintiff appears to substitute suspicion for evidence, particularly as the prior established course of dealing arguably placed a duty on the plaintiff to inquire or object if he wished to change the terms. By requiring the defendant to prove she gave explicit notice for a return process that had previously operated without such formality, the court imposes a new obligation retroactively. This undermines the very course of performance doctrine it invokes, creating a moving standard that jeopardizes commercial predictability. The judgment protects the plaintiff from a surprise return of “so large and substantial a part” of a shipment, but it does so by unsettling the established behavioral contract between the parties, which is a questionable trade-off in contract law.
