Whether a subcontractor that justifiably stops work after the prime contractor's material breach may elect quantum meruit recovery in a Miller Act action rather than sue solely for contract damages.
Holding
Yes. A nonbreaching subcontractor may recover in quantum meruit for the reasonable value of labor and equipment it furnished, and that remedy is available against both the prime contractor and its Miller Act surety.
Reasoning
The district court's unchallenged finding established that Blair materially breached the subcontract by refusing to make the required crane-rental payments. Coastal therefore was justified in terminating its own performance rather than continuing under the breached agreement.
A promisee injured by a material breach may choose to forgo a contract action and seek restitution for the reasonable value of performance already supplied. This principle is especially applicable in construction disputes, where a contractor's partial work and supplied equipment may remain valuable to the party that breached.
Coastal paid the costs of providing labor and crane use, while Blair retained the resulting benefits without fully paying for them. Restitution prevents Blair from being unjustly enriched by its own breach and restores the value of benefits Coastal conferred.
The Miller Act does not restrict this remedy to a claim against the prime contractor alone. Quantum meruit recovery may also be sought from the Miller Act surety, consistent with the Act's protective purpose for subcontractors and suppliers on federal projects.
