Restatement Second of Contracts § 374
Restitution in Favor of Party in Breach
- Subject to the rule stated in Subsection (2), if a party justifiably refuses to perform on the ground that his remaining duties of performance have been discharged by the other party's breach, the party in breach is entitled to restitution for any benefit that he has conferred by way of part performance or reliance in excess of the loss that he has caused by his own breach.
- To the extent that, under the manifested assent of the parties, a party's performance is to be retained in the case of breach, that party is not entitled to restitution if the value of the performance as liquidated damages is reasonable in the light of the anticipated or actual loss caused by the breach and the difficulties of proof of loss.
