Cure After Nonconforming Tender
A buyer rejected a shipment of parts that arrived with minor cosmetic flaws. The seller had reasonable grounds to believe the buyer would accept the parts with a price allowance. After seasonable notice, the seller obtained additional time to deliver conforming replacements.
Divisible Contribution to Single Harm
Two factories discharged pollutants into a river at different times, causing a single fish kill. Evidence permitted a reasonable basis for determining each factory's contribution to the total harm. Liability was apportioned between the factories rather than imposed jointly.
Demand for Assurance After Layoffs
Noon Cars learned that Crown Automotive had suffered a plant fire, laid off staff, and missed prototype deadlines. These events created reasonable grounds for insecurity about Crown's ability to meet future orders. Noon Cars sent a written demand for a detailed recovery timeline and suspended further commitments.

School officials received reports that a student had hidden contraband in a locker. The reports supplied reasonable grounds to believe school rules had been violated. Officials conducted a targeted search that was reasonably related to the suspected infraction and not excessively intrusive.
Common questions
Frequently Asked
3
What constitutes reasonable grounds for demanding adequate assurance in a sales contract?+
Objective facts showing a real possibility of nonperformance create reasonable grounds. An incomplete delivery combined with reports of facility damage, for example, justified a written demand. Between merchants the adequacy of any response is judged by commercial standards.
Supporting sources
How does reasonable grounds differ from probable cause in criminal procedure?+
Reasonable grounds permit certain school searches and some statutory disclosures without a warrant. Probable cause is required for most criminal warrants. The lower threshold reflects the reduced privacy expectation in the school setting or the limited scope of the statutory procedure.
Supporting sources
When does a response to a demand for assurance fail to satisfy reasonable grounds concerns?+
A vague statement of commitment without timelines or supporting documentation is usually inadequate. Commercial standards in the relevant industry determine what level of detail is required after prior defects have been reported. Failure to provide adequate assurance within a reasonable time constitutes repudiation.
