This was a civil action heard on an appeal taken by the defendants from the judgment of a justice of the peace. In December, 1923, the plaintiffs purchased from the defendants a house and lot and agreed to pay therefor the sum of $5,500. They paid $500, assumed a first mortgage indebtedness represented by the defendants to be $2,846.94 due the Acacia Mutual Life Association, and secured the remainder by the execution of a second mortgage. The amount originally due the Life Association was $3,000, and the defendants told the plaintiffs they had paid thereon $153.06, thereby reducing the indebtedness to $2,846.94. The plaintiffs alleged that they had afterwards learned that in the payment of $153.06 was included the sum of $88, which was interest on the debt and not a part of the principal which they had agreed to pay. The object of the action is to recover this sum as an overcharge or a sum in excess of the agreed price. Under instructions, to which there was no exception, the jury returned a verdict finding that the plaintiffs were entitled to a credit of $86.00 as a charge in excess of the sum due on the first mortgage. There was a motion for nonsuit on the ground that the mortgage was a matter of record, and that all the facts were known to the plaintiff when the trade was made. The motion was denied.
One of the sources of obligations created by quasi-contracts is the receipt of a benefit, the retention of which, without compensation, would constitute "unjust enrichment," illustrated by money paid under a mistake of fact. Woodward, Quasi-Contracts, sec. 1. If the defendants were not entitled to the alleged overcharge, a fact made certain by the verdict, they had no right to retain it. The principle as stated by Greenleaf is quoted in Bahnsen v. Clemmons, 79 N.C. 556: "When the defendant is proved to have in his hands the money of the plaintiff, which ex equo et bono he ought to refund, the law conclusively presumes that he has promised to do so, and the jury are bound to find accordingly; and after verdict the promise is presumed to have been actually proved."
The appellants interposed a demurrer on the ground that a justice of the peace had no jurisdiction of the action and that as the jurisdiction of the Superior Court was derivative, none was acquired by the appeal. The action was brought, not to correct or reform the note, but to recover money which otherwise would go to the "unjust enrichment" of the defendants. This will appear by reference to the justice's summons which, in the absence of a more formal pleading, may be regarded as a substitute for the complaint.Allen v. Jackson, 86 N.C. 321; Cromer v. Marsha, 122 N.C. 563; Parkerv. Express Co., 132 N.C. 128. For this reason we need not advert to decisions dealing with the *Page 354 question whether a justice of the peace in any event can administer equitable relief. There is a distinction, however, between declaring an equity and enforcing the collection of money which equitably belongs to a party. Fidelity Co., v. Grocery Co., 147 N.C. 510; Stroud v. Ins. Co.,148 N.C. 54.
