[¶ 1.] In this breach of contract, conversion, and unjust enrichment case, the circuit court held that defendants were unjustly enriched by plaintiff's services, after a jury rendered a verdict in favor of defendants on plaintiffs breach of contract and conversion claims. On appeal, we reverse the court's damages award against one defendant because two express contracts govern the rights between that defendant and plaintiff. In regard to the defendant with no express contractual relationship with plaintiff, we affirm the court's finding of unjust enrichment, but reverse and remand for a proper calculation of damages.
[¶ 2.] In early March 2005, Michael Johnson and Robert Larson entered into an oral contract whereby Johnson agreed to remove rock from Larson's farmland in exchange for Johnson receiving the value of the rock removed. Larson is a retired farmer who owns farm and pasture land near Madison, South Dakota. Johnson operates Michael Johnson Construction and owns two mining pits, one east, and one west, of Madison. Shortly after Johnson began removing rock from Larson's land, the two entered into a second oral agreement. In exchange for Johnson's right to keep the excavated rock extracted from Larson's land, Johnson agreed to install drain tile in a low lying area of Larson's farmland.
[¶ 4.] Joel Penny is a farmer in Decatur, Nebraska. While visiting Flandreau in July 2006, Penny learned that Larson had rock on his land that he wanted removed. Penny contacted Larson. Larson informed Penny that he and Johnson had previously agreed that Johnson would remove the rock from his land. Larson told Penny that after excavating the rock, Johnson had not come back to actually remove the rock he had stockpiled since the spring of 2005. Larson told Penny that he had inquired several times about when Johnson intended to remove the stockpiles. Larson also told Penny that he would contact Johnson to ask whether Johnson intended on removing the rock.
[¶ 5.] In August 2006, Penny again contacted Larson about removing the rock. Larson believed Johnson had no intention of removing the stockpiled rock, based on the fact he had not heard from Johnson, even after leaving his number with Johnson's bookkeeper. Ultimately, Larson gave Penny permission to remove the rock. Penny paid Larson nothing for the rock. He removed approximately 50 semi-truck loads from Larson's land. Penny estimated that he took approximately 25 loads from the rock pile stocked by Johnson.
[¶ 6.] In October 2006, Johnson learned that his rock piles were no longer on Larson's land. He sent an invoice to Larson on October 24, 2006, for his services in excavating and removing the rock. Johnson also included an invoice for the installation of the drain tile. He enclosed a letter with the invoices reminding Larson of the parties' oral agreement that Johnson was to receive the rocks in exchange for clearing them from Larson's land. Larson neither responded to the letter nor paid the invoice.
[¶ 7.] On January 11, 2007, Johnson brought suit against Larson for breach of contract, conversion, restitution, constructive trust, and unjust enrichment. He amended his complaint in April 2007, to include Penny as a defendant and removed the restitution cause of action. A jury trial was held November 17 through November 20, 2008, on the breach of contract and conversion claims. The jury returned a verdict in favor of Larson and Penny. On January 8, 2009, a hearing was held in the circuit court to consider Johnson's equitable claims. On May 13, 2009, the court entered a judgment against Larson and Penny jointly and severally. The court concluded that Larson and Penny were unjustly enriched by the labor, equipment, and materials provided by Johnson for the removal of the rock. The court further concluded that Larson was unjustly enriched by the labor, equipment, and materials provided for the installation of drain tile. On appeal, Larson and Penny assert that the court erred when it concluded that they were unjustly enriched by Johnson.
Analysis and Decision
[¶ 8.] Penny and Larson claim, among other things, that because the jury rendered a verdict against Johnson on his breach of contract and conversion claims, the court erred in allowing Johnson unjust enrichment damages on the same facts. We recently held that the equitable remedy of unjust enrichment is unwarranted when the rights of the parties are controlled by an express contract. Burch v. Bricker, 2006 SD 101, ¶ 18, 724 N.W.2d 604, 609-10 (quoting Mooney's, Inc. v. South Dakota Dept. of Transp., 482 N.W.2d 43, 47 (S.D.1992)) (discussing quantum meruit) (additional citation omitted). Unjust enrichment contemplates an involuntary or nonconsensual transfer, unjustly enriching one party. The equitable remedy of restitution is imposed because the transfer lacks an adequate legal basis.
[¶ 9.] When there is a valid and enforceable contract, however, liability for compensation or other resolution of the breach is fixed exclusively by the contract. Nadeau v. Pitman, 731 A.2d 863, 866-67 (Me.1999); County Comm'rs of Caroline County v. J. Roland Dashiell & Sons, Inc., 358 Md. 83, 747 A.2d 600, 607 (2000) (citing many courts holding the same); Leasepartners Corp. v. Robert L. Brooks Trust, 113 Nev. 747, 942 P.2d 182, 187 (1997); see also JN Exploration & Prod. v. Western Gas Resources, Inc., 153 F.3d 906, 910 (8th Cir.1998) (applying North Dakota law). In the contract framework, benefits are voluntarily conferred and transfers are consensual.
[¶ 10.] No one disputes that Johnson and Larson entered into two valid and enforceable contracts. The first permitted Johnson to remove rock from Larson's farmland in exchange for Johnson receiving the value of the rock removed. The second permitted Johnson to remove rock and receive the value of that rock in exchange for installing drain tile on Larson's land. Because there existed two express contracts, and the benefit conferred on Larson was specified as part of the parties' contracts, Johnson had a valid remedy at law. See Restatement (Third) Restitution § 2 (unjust enrichment can apply in a contract context when the performance received was not specified by the contract). Johnson voluntarily and consensually conferred the benefit of drain tile and rock removal to Larson as part of the parties' valid and enforceable contracts. Therefore, there was no room for a court to imply a promise by Larson to pay Johnson, as the parties expressly fixed their rights and obligations: Johnson's remedy lay in a claim for breach of contract. See County Comm'rs of Caroline County, 747 A.2d at 607 (citation omitted). The court erred when it acted in equity to impose restitution against Larson.
[¶ 11.] As between Johnson and Penny, however, there was no express contract controlling the parties' relationship. Therefore, an equitable remedy was available. To prevail on a claim for unjust enrichment, Johnson was required to prove that Penny received a benefit, Penny was aware he was receiving a benefit, and it would be inequitable to allow Penny to retain the benefit without paying for it. See Hofeldt, 2003 SD 25, ¶ 16, 658 N.W.2d at 788 (citations omitted). Here, the court found that Penny received the benefit of Johnson's excavation services. The court further found that Penny was aware he
[¶ 12.] The transfer between Johnson and Penny is the very type of event contemplated by the doctrine of unjust enrichment. Johnson expended many hours and employed the use of expensive heavy machinery to excavate tons of rock from Larson's land. He stored the rock to be removed at a later date. It was not left for anyone's taking. Penny was aware of Johnson's efforts and removed and retained the rock without Johnson's knowledge or consent. The transfer of Johnson's efforts and Johnson's rock to Penny was involuntary and nonconsensual. Also, because there was no express contract between Johnson and Penny, Johnson had no remedy at law to recover for the rock removed. Thus, based on our review of the record, there was ample support for the court to find that Penny was unjustly enriched by Johnson's efforts.
[¶ 13.] What is the appropriate measure of damages when one is unjustly enriched by another's efforts? According to Penny, the proper measure of restitution for an unjust enrichment claim is the value to the person receiving the benefit rather than the cost to the person providing it. Relying on the doctrine of quantum meruit, Johnson argues that when one benefits by the labor and materials of another the proper measure of restitution is the reasonable value of labor and materials furnished. See Karras v. Alpha Corp., 528 N.W.2d 397, 400 (S.D.1995). In the circuit court's view, Johnson was entitled to the reasonable value of labor and materials he provided to Penny. In reaching this conclusion, the court held that "[q]uantum meruit is an equitable remedy to provide restitution for unjust enrichment."
[¶ 14.] While unjust enrichment and quantum meruit are similarly based on an inequity in allowing a person to retain a benefit without having to pay for it, the two doctrines are not interchangeable.
[¶ 15.] Unjust enrichment, on the other hand, allows an award of restitution for the value of the benefit unjustly received, rather than the value of the service provided. Lindquist Ford, Inc., 557 F.3d at 477; Aladdin Elec. Assoc., 645 A.2d at 1145; Ramsey, 484 N.W.2d at 333. The defendant must be unjustly enriched. However, the reasonable cost of the services provided can be evidence of the value of the benefit conferred. See Aladdin Elec. Assoc., 645 A.2d at 1145.
[¶ 16.] Here, there was no basis to find an implied contract between Johnson and Penny. As the court recognized, Johnson was unaware that Penny removed the rock. Moreover, neither Johnson nor Penny were wrongdoers: the court found that Penny had no intent to deprive Johnson of the value of his rock. Therefore, although the court was correct in finding that Penny was unjustly enriched, it erred when it further held that quantum meruit was the proper remedy to provide Johnson restitution. The proper measure of damages in this case is the benefit conferred on Penny.
[¶ 17.] In summary, the court erred when it acted in equity to impose a judgment against Larson for unjust enrichment when two valid and enforceable contracts controlled the parties' relationship and a jury had previously found for Larson on Johnson's breach of contract claim. The court did not abuse its discretion when it found that Penny was unjustly enriched by Johnson's services. But the court erred when it applied the remedy of quantum meruit to an unjust enrichment claim. Accordingly, we reverse the court's judgment against Larson, affirm the court's finding of unjust enrichment against Penny, and remand for the court to determine the proper measure of damages against Penny consistent with this opinion.
[¶ 18.] Affirmed in part, reversed in part, and remanded.
