delivered the opinion of the Court.
This action was brought by respondent to foreclose a mortgage made in December, 1932, by Carpenter. At that time § 1083 of the New York Civil Practice Act provided that the amount of the deficiency judgment was to be measured by the residue of the debt remaining unsatisfied after a sale of the mortgaged property and the application of the proceeds pursuant to the directions contained in the judgment. In November, 1938, a judgment of foreclosure and sale was entered for $18,401.25, and in December, 1938, the foreclosure sale was held at which the property was purchased by respondent’s nominee for $4,000. The referee, appointed by the court to sell, reported a deficiency which after the inclusion of taxes, fees and expenses was computed at $16,162.12. Respondent moved to confirm the referee’s report of sale and asked that a deficiency judgment be entered for that amount. Petitioner took exceptions to the report and made a cross-motion to have the court fix the value of the property for the purpose of determining the amount of the deficiency judgment on the ground that the sale
*228
price was “wholly inequitable and unconscionable.” A new § 1083

(L. 1938, ch. 510), effective April 7, 1938, provides in substance that the court in determining the amount of a deficiency judgment should, on appropriate motion, “determine, upon affidavit or otherwise as it shall direct, the fair and reasonable market value of the mortgaged premises” and should deduct from the amount of the debt the “market value as determined by the court or the sale price of the property whichever shall be the higher.” The right to recover any deficiency is made de

We take a. different view. 4
. The formula which a legislature may adopt for determining the amount of a deficiency judgment is not fixed .and invariable. That "which exists at the date of the execution of the mortgage does not become so embedded in the contract between the parties that it cannot be constitutionally altered. As this Court said in

The control of judicial sales of realty by courts of equity and by legislatures in order to prevent sacrificial prices has.a long history. Weiner, Conflicting Functions of the Upset Price, 27 Col. L. Rev. 132,133,

In chancery sales in England during-the eighteenth century, there developed the practice of opening the bidding, prior to confirmation, on an offer to advance the price 10 per cent.
Graffam
v.
Burgess,
We mention these matters here because they indicate that for about two centuries there has been a rather continuous effort, either through general rule or by appeal to the chancellor in specific cases, to prevent the machinery of judicial sales from becoming an instrument of oppression. And, so far as mortgage foreclosures are con *233 cerned, numerous devices have been employed to safeguard mortgagors from sales which will, or may, result in mortgagees collecting more than their due. The variety of formulae which has been employed to that end is ample evidence not only of the intrusion which advanced notions of fairness have made on the earlier coi.-cern for stability of judicial sales but also of the flexibility of the standards of fairness themselves. Underlying that change has been the realization that the price which property commands at a forced sale may be hardly even a rough measure of its value. The paralysis of real estate markets during periods of depression, the wide discrepancy between the money value of property to the mortgagee and the cash price which that property would receive at a'forced sale, the fact that the price realized at such a sale may be a, far cry from the price at which the property would be sold to a willing buyer by a willing seller, reflect the considerations which have motivated departures from the theory that competitive bidding in this field amply protects the debtor.
Mortgagees are constitutionally entitled to no more than payment in full.

Honeyman
v.
Jacobs, supra.
They cannot be heard to complain on constitutional grounds if the legislature takes steps to see to it that they get no more than that. As we have seen, equity will intervene in. individual cases where it is palpably apparent that gross unfairness is imminent. That is the law of New York.
In conclusion, the statute in question, like the one involved in
Richmond Mortgage & Loan Corp.
v.
Wachovia Bank & Trust Co., supra,
p. 130, “cannot fairly be said to do more than restrict the mortgagee to that for which he contracted, namely, payment in full.” Here, as in that case, the obligation of the mortgagee’s contract is recognized; the statute does no inore than limit
*235
“that right so as to prevent his obtaining more than his due.”
Id.,
p. 130. To be sure, the mortgagee retained in that case an alternative remedy, while in the instant one the Court of Appeals has said that under New York -law there remained no alternative remedy “substantially coextensive” with that which had been removed. But it is clear from

Notes
That section provides:
“Judgment for deficiency; limitation. If a person who is liable to the plaintiff for the payment of the debt secured by the mortgage is made a. defendant in the action, and has appeared or has been personally served with the summons, the final judgment may award payment by him of the whole residue, or so much thereof as the court may determine to be just and equitable, of the debt remaining unsatisfied, after a sale of the mortgaged property and the application of the proceeds, pursuant to the directions contained in such judgment, the amount thereof to be determined by the court as herein provided. Simultaneously with the making of a motion for an order confirming the sale provided such motion is made within ninety days after the date of the consummation of the sale by the delivery of the proper deed of conveyance to the purchaser in all cases where the sale is held after the date this section as hereby amended takes effect, and in all cases where the sale was held prior to the date this section as hereby amended takes effect and said sale has not heretofore been confirmed, then within ninety days from the date this section as hereby amended takes effect or within ninety days after the date of the consummation of the sale by delivery of the proper deed of conveyance to the purchaser, regardless of whether the sale was held prior or subsequent to or on the date this section as hereby amended takes effect, the party to whom such residue shall be owing may make a motion in the action for leave to enter a deficiency judgment upon notice to the party against whom such judgment is sought or the attorney who shall have appeared for such party in such action. Such notice shall be served personally or in such other manner as the court may direct. Upon such motion the court, whether or not the respondent appears, *229 shall determine, upon affidavit or otherwise as it shall direct, the fair and reasonable market value of the mortgaged premises as of the date such premises were bid in at auction or such nearest earlier date as there shall have been any market value thereof and shall make an order directing the entry of a deficiency judgment. Such deficiency judgment shall be for an amount equal to the sum of the amount owing by the party liable as determined by the judgment with interest, plus the amount owing on all prior liens and encumbrances with interest, plus costs and disbursements of the action including the referee’s fee and disbursements, less the market value as determined by the court or the sale price of the property whichever shall be the higher. If no motion for a deficiency judgment shall be made as herein prescribed the proceeds of the 'sale regardless of amount shall be deemed to be in full satisfaction of the mortgage debt and no right to recover any deficiency in any action or proceeding shall exist. . . .”
An affidavit of a real estate broker submitted by petitioner in support of his cross-motion stated that in his opinion the fair market value of the property was $11,000. An affidavit of an appraiser submitted by respondent in opposition stated that in his view the fair market value of the property was $6,500. The property was assessed by New York City for tax purposes at $15,000.
The moratory deficiency judgment act did not apply to mortgages or connected agreements dated on or after July 1, 1932. See
We are concerned here solely with the application of this statute to a situation where the mortgagee purchases the property at foreclosure' sale. We intimate no opinion on its constitutionality as applied to the case where the mortgagee is not the pui Phaser.
