Then, why is the bond, within the purview of a court of equity, looking at the real facts, any less a superscdeas bond, here and now, upon the principle of treating that as done which ought to " be done? "It is a peculiar excellence in chancery, on many occa- sions, that it goes behind writings, and even sealed instruments and judgments, to ascertain how the original transaction stood, and what were its true obligations, in order to enforce them." U. S. v. Price, 9 How. 83, 102. If, therefore, the defendants have been defeated of I their intention—and they had the right of absolute choice upon exe- cuting the statutory bond, so that it need not be a mutual mistake, since the plaintiffs had no choice as to the terms of the contract—to give a supersedeas bond, which would have suspended the plaintiH’s ` right of property, and, as a consequence of that suspension, any right of possession pending the appeal, by a mistake relievable in equity in favor of the plaintiffs, if they desired it, I do not see any reason why the plaintiffs should not be, in a court of equity, called on to act in the premises wherever the matter is involved, left to resort to that remedy, or else compelled to accept the defendants' offer to make the bond complete. Of course, only upon any just terms as to security or indemnity, and that containing the same condition as the statu- tory bond would be just; or an amendment of the defective bond to conform to the statute, by the consent of the surety, would be just, and precisely what a court of equity on a bill to reform the contract would grant. On this reasoning, if it be correct, the right of this court to direct the amendment or a new bond does not depend on any jurisdiction it may have over the instrument qua a supersedeas bond, or any an- thority over the appellate proceedings which might be deemed a usur- r pation, but only on the fact that, having lawful custody of the res, and , a plenary discretion to allow or refuse a surrender of it to the plain- tiffs on their application to enforce the decree, (so far as the decree relates alone to that custody, and no further,) it may exercise that authority according to the demands of the equitable considerations here suggested, and refuse to deliver possession to the plaintiffs in spite of their unsuperseded decree, if the defendants shall voluntarily correct the mistake. And it should be remembered here that, by in- voking this extraordinary authority of the court over its receivers to continue them or not upon these equitable considerations, we neither create nor restore the statutory supersedeas, do not substitute another, nor affect the rights ofthe plaintiffs growing out of any want of one. We simply and independently, upon our own terms, withhold pos- session from them until the supreme court can act. To show this distinction, let us imagine that no supersedcas bond had been given at all, or attempted or intended to be given, but, before the receiver was discharged, the defendants, by motion or petition, should apply to this court to continue the receiver, or to appoint one originally, pending the appeal, and we should rightfully or wrongfully do that, is it not
