A material breach of an accord is the non-performance of a duty that justifies the injured party in regarding the whole transaction as at an end.[i]

An accord is enforceable as a contractual agreement in its own right.[ii]  An action may be maintained against the party in default for the breach or nonperformance of an accord under ordinary contracts principles.[iii]  The obligee may enforce either the original duty or any duty pursuant to the accord, if the obligor materially breaches the accord.
