Appellants’ premises were leased in 1919 for 99 years by the City National Bank of Lansing, Michigan. For the period ending April 1, 1927, a fixed rental was prescribed, payable quarterly in advance. The lease provided that for each ten year term thereafter, the rental should be agreed upon by the parties, and, in case of failure so to agree, it should be determined by referees. The parties agreed on rentals of $600 per month, payable quarterly in advance, for the period from April 1, 1927, to March 31, 1937, and these sums were accordingly paid during that time, by the City National Bank, until it was taken over by the Capital National Bank. Thereafter, a receiver was appointed for this bank, and the same rentals were paid by the receiver for three years after his appointment until the expiration of such ten year period.
Appellants and the receiver, however, were unable to agree on rentals for the new ten year period, beginning on April 1, 1937, and referees were appointed, in accordance with the lease provisions, to determine the rentals to be paid.
After the expiration of 20 months from the time of the last payment of the agreed rentals, the referees rendered an award, determining that the fair rental for the period beginning April 1, 1937, and ending March 31, 1947, “is $725.00 per month, payable quarterly in advance.” The award was dated September 1, 1939.
On October 12, 1939, the receiver paid appellants a sum equivalent to the rentals up to and including that date, and for the ensuing quarter. Appellants demanded interest on the payments for the period of twenty months during which no rental had been paid, and, upon the receiver’s refusal, brought suit therefor in the Circuit Court for Ingham County, State of Michigan, which was removed to the District Court, on the ground that it involved matters concerning the winding up of a national bank. . :
The District Court held that interest is allowable only when provided for by contract, express or implied; or by statute; or when, as damages, it becomes due after a default by the person liable to pay; that appellants had established no right to interest by express or implied contract; or by statute; and since the receiver could not be in default until the amount of rental was ascertained, interest could not be allowed prior to the award.
It is agreed that the determination of the issue in this case depends upon the application of the law as announced by the courts of Michigan, if precedents are available; and under these circumstances, we will consider the case accordingly, as our conclusions would not vary, whether the case be decided under Michigan authority, or not. As to the application of Erie R. Co. v. Tompkins,
Numerous cases are cited by both parties in their contentions that the law, as *938 expressed in the decisions of the courts of Michigan, sustain their claims, and it, therefore, becomes necessary to examine these various adjudications.
Mitchell v. Reolds Farms Co.,
Emphasis is placed upon Lake Shore & Michigan Southern R. R. v. People,
Other authorities cited by appellee are distinguishable. In Coburn v. Muskegon Booming Co.,
Resuming consideration of the cases cited by appellee, in People ex rel. Reeder v. Wexford County Treasurer,
Practically all of the authorities cited by appellants are to the effect that interest may be allowed on money illegally or improperly withheld, or property converted; but it cannot be said that appellee illegally or improperly withheld money to which appellants were entitled. It was provided by the contract between the parties, that referees would be appointed to fix the rent payable, and since there is no record of any improper delay caused by appellee, it could not be said that rentals were improperly retained, until it was decided what the rentals would be.
The foregoing cases do not persuade us to the conclusion that, according to the law as expressed by the courts of Michigan, the allowance of interest is confined to cases of wrongful detention of property or money, nor that it is denied on the ground that damages suffered, are un-liquidated. At the same time our attention is not directed to any case of that jurisdiction, which holds that interest is allowable, in cases where the party sought to be charged therewith was guiltless of such wrongful nonpayment or detention, or some tortious conduct resulting in loss to a claimant. But we are of the opinion that it is not necessary for a claimant to rely upon tort or wrongful conduct in order that he recover interest, as, under the circumstances of this case, there is implied in law, an agreement to make such payment.
Appellants count upon indebitatus assumpsit. This action, while legal in form, is equitable to the core. Where one has in his hands money which, according to the rules of equity and good conscience, ought to be paid to another, assumpsit is the proper form of remedy; and if, at the time of commencement of action, a party holds money which, ex aequo et bono, he ought not to have retained from plaintiffs, they are entitled to recovery. Beardslee v. Horton,
The essential elements of a quasi contractual obligation, upon which a recovery may be had, are the receipt of a benefit by a defendant from a plaintiff, which benefit it is inequitable that the defendant retain. Ever since an action for money had and received has been maintainable, it has been employed as a remedy to prevent the unjust enrichment of one at the expense of another, or to prevent one from retaining a benefit conferred upon him by another which would- be, under all of the circumstances of the case, unjust or inequitable. Richland County Bank v. Joint School Dist. No. 2,
Applying the law to the facts in this case, appellee retained and used the premises for a period of 20 months, while arbitration proceedings were under way to establish an agreed fair rental therefor. During this period, appellants were deprived of the receipt of rental, and appellee had the use of the premises, as well as the use of the money representing the fair rental value. When the referees determined such rental value, it expressly dated back to the beginning of the period during which the rentals had remained unpaid. Equity and fairness require that appellants have restitution, by way of interest, bn the rentals unpaid during that period. Otherwise, appellee would receive the benefit of the value of the use of such money, to the disadvantage of appellants, and his retention thereof would result in inequity and unjust enrichment at their expense. It is our conclusion that appellants are entitled to the interest" claimed. Other questions raised are not sufficiently pertinent to require discussion.
The judgment is reversed and the case remanded to the District Court for entry of judgment in accordance herewith.
