CARDOZO, Ch. J.

Plaintiff, a municipal corporation, brought an action to restrain defendant from erecting or operating a gasoline station on land bordering upon a city street. A temporary injunction was granted without security or condition. A trial followed, and ended in a judgment dismissing the complaint. Plaintiff moved for a stay of the construction of the station during the pendency of an appeal. The motion was granted "on the express condition that the plaintiff pay to the defendant all damages sustained by reason thereof and by reason of the order made herein restraining the defendant," provided the appellate court finally decided that the plaintiff was not entitled to the restraining order or to the injunction asked for in the complaint. The plaintiff took the benefit of this order, and acquiesced in its conditions. Upon the affirmance of the judgment the defendant moved for the appointment of a referee to assess the damages. An order for that relief, granted at Special Term, was reversed at the Appellate Division on the authority of City of Yonkers v. Federal Sugar Refining Co. ( 221 N.Y. 206).

We think the case at hand is untouched by that decision. There the situation was the same as it would be here if a stay had not been granted subject to a condition. What was there attempted was to charge the city of Yonkers with the damages resulting from a temporary injunction though no condition had been imposed and no security given. Liability was thought to follow from Code Civil Procedure, section 1990 (now Civil Practice Act, §§ 162, 820), to the effect that wherever a municipal corporation was exempted by the statute from the requirement of security upon procuring an order of injunction, it should be liable for all damages "in the same case and to the same extent as sureties to an undertaking would have been if such an undertaking had been given." We held that liability did not arise by force of the statute without more unless the "extent" of the maximum obligation had been measured by the order.

The question before us here is not one of liability by force of the provisions of a statute. It is one of liability by force of the acceptance of a condition imposed in return for the concession of a discretionary remedy. The city was required to assume liability for damages without arbitrary limit, or else give up the stay. We are not concerned to inquire whether the condition was erroneous. At least it was not void. The city was not at liberty to accept the benefit of a discretionary order, and reject the attendant burden. It might have refused the benefit of the stay, and let the judgment take its course. It might have appealed from the order denying relief except upon compliance with an overburdensome condition. It did nothing of the kind. It took the benefit of the stay and now rejects the condition as if the order had been absolute. Condition and benefit are not so easily dissevered.

We assume that the statute imposes a restriction upon power when it forbids a court or judge to require "security" from a municipal corporation as a condition of an injunction or of any other relief (Code Civ. Pro. § 1990; Civ. Prac. Act, § 162). The purpose of that provision is to relieve a municipal corporation of an obligation to furnish sureties or cash. There is no exaction of "security" in the sense of the prohibition when a city is made to pledge its own credit in return for benefits received. The lawmakers cannot have meant that it should be beyond the power of the court to impose equitable terms for an equitable remedy. A distinction must be drawn, moreover, between duty and discretion. Amendments of the statute have put upon the court a duty, when it grants an injunction to a municipal corporation, to give the defendant the benefit of some measure of protection, a personal liability within the limits appropriate for sureties. Failure to make provision to that extent is a denial of a legal right of which a defendant may complain. We do not read the statute as depriving the court of its discretionary power to impose a condition even heavier, to make the stay dependent upon an assumption of liability for damages without arbitrary limit. Such a power has long been exercised by courts of equity as an effective expedient for the adjustment of "its plastic remedies" ( City of Yonkers v. Fed. Sugar Ref. Co., supra, at p. 209; Mooney v. Byrne, 163 N.Y. 86, 97). An inroad upon a jurisdiction so inveterate and traditional will not be gathered as an inference from statutes of uncertain meaning.

The case is not affected by Civil Practice Act, section 571, which provides that "upon an appeal taken by a domestic municipal corporation, * * * the service of the notice of appeal perfects the appeal and stays the execution of the judgment or order appealed from, without an undertaking or other security, unless the court requires security to be given." The judgment in this case was one for the dismissal of the complaint. A notice of appeal had the effect of staying automatically the collection of the costs. It did not automatically revive or continue an injunction which was to last only during the suit and which fell by its own terms when the suit had been determined.

Authoritative decisions are to the effect that the proceeding is not strictly a motion in the action, but rather one outside of it, and so appealable of right. ( Lawton v. Green, 64 N.Y. 326, at pp. 330, 331; Sargent v. St. Mary's Asylum, 190 N.Y. 394; City of Yonkers v. Fed. Sugar Ref. Co., supra).

The order of the Appellate Division should be reversed, and that of the Special Term affirmed, with costs in the Appellate Division and in this court.
