The opinion of the court was delivered by

This bill was filed to foreclose a first mortgage upon lands in Hudson county. It alleged that the mortgagor had given a second mortgage to A. S. Boyd, on the same premises; that Boyd had foreclosed his mortgage, and that on his foreclosure, the sheriff had sold and conveyed the premises in fee, to Boyd, and then charged that said premises were sold to Boyd with full notice of complainant’s mortgage, and subject to the lien thereof. The defendant, Boyd, answered, admitting the complainant’s mortgage, his own subsequent mortgage, his foreclosure, and the sale to himself, as stated in complainant’s bill, and then, with requisite particularity, set up usury, in the complainant’s mortgage, to the amount of $200. The proofs fully establish the usury as alleged; but the vice-chancellor refused to give effect to such defence, because of the averment in the bill, undenied in the answer, that the property was sold on the prior foreclosure, subject to comulainant’s mortgage. From the decree thereupon *602made, Boyd appeals, and thus is presented the question for decision.

The principles governing the case have been already settled in this court.

The defence of usury in a mortgage may be set up by the mortgagor, or by any one claiming under and in privity with him, as, for example, by subsequent mortgagees, or by purchasers at sheriff’s sale. Brolasky v. Miller, 1 Stock. 807.

But the mortgagor may waive the usury, and then those holding under him, by subsequent conveyance, cannot avail themselves of the defence; likewise, one who has acquired from the mortgagor the right to plead the usury, may also remove the taint as to himself, and those thereafter deriving title from him. Warwick v. Dawes, 11 C. E. Gr. 548.

From these principles, it follows that Boyd possesses the right to reduce the complainant’s mortgage for usury, both in his capacity as mortgagee and as purchaser at sheriff’s sale, unless the mere averment that at such sale the property was sold subject to the complainant’s mortgage, shows a defeasance, of the right.

It has been held that if the mortgagor convey the property by deed, expressly subject to the amount of the existing mortgage, the grantee cannot set up the usury, for such language imports a waiver. But no case is cited to the effect that a sheriff, selling lands under aft. fa. against the mortgagor, to satisfy a subsequent mortgage which itself preserved the defence, has any power so to purge the taint. And, plainly, he can have none. His duty is to sell the property, in the interest of the defendant and the second mortgagee, for the best price it will bring, and obviously, he would be defeating this-aim, if he should impose conditions preventing the purchaser from asserting the rights concerning the land, which these parties possess. He has no power to do so. His sale and conveyance transfer to the purchaser the same right to allege the usury in the previous mortgage as they whose estate he conveys, had, and though he declare, at his auction and in his deed, that he sells subject to the prior encumbrance, such assertion cannot create a waiver of the right to plead the usury; it is * *603a mere notice, which he may fairly give, to apprise persons of what claims may be made against the title he conveys.

We conclude, therefore, that the bill does not state any facts from which the waiver of the defence for usury is the legitimate inference, and that consequently the decree below should be reversed.
