delivered the opinion of the Court.
The first question presented is whether non damnificatus is a good plea to the declaration. The solution of this question depends upon the true construction and legal effect of the covenant. Is it a covenant to indemnify merely ?
The rule on this subject is this. Where the covenant, or, (in the case of a bond with a condition,) the condition is merely to indemnify, this plea is sufficient; but where it stipulates to perform any particular act, the performance must be specially pleaded. In 1 Saund. R. 117, hi, it is laid down that “this plea cannot be pleaded where the condition is to discharge or acquit the plaintiff from such a bond, or other particular thing, for then the defendant must set forth affirmatively the special manner of performance and numerous authorities are cited in support of this position. “But” it is added, “it is otherwise where the condition is to discharge and acquit the plaintiff from any damage by reason of such bond or other particular thing, for that is in truth the same thing with a condition to indemnify and save harmless.” The distinction taken, is between a bond or covenant to discharge or acquit from the obligation itself, and one to discharge or acquit from any damage by reason of the obligation. Holmes v. Rhodes, 1 Bos. & Pull. R. 638, is strongly analogous to the present case. The action was upon a bond, conditioned that the obligors should pay the amount of a bond for which the plaintiff had become a surety, and thereby acquit, release and discharge the plaintiff, of and from the obligation, and all sums of money to grow due thereon, and damages, &c. The object was indemnity. But the condition was to acquit and discharge by payment. The plea of non damnificatus was interposed, but, after replication and demurrer, the Court, going back to the first error, held the plea bad. To the same effect is the case of *270Woods v. Rowan, 5 John. R. 42, and the various cases found in the New York Reports, on bonds to sheriffs for goal liberties. These bonds are designed for the indemnity of the sheriff, but provide against an escape. The same principle is found in Andrus v. Waring, 2 John. R. 153, in the case of Negus, 7 Wend. R. 499, and in the case of McClure v. Erwin, 3 Cow. R. 213. In the last case the Court say: “ This is a good plea in all cases where the condition is to indemnify and save harmless; because it answers the condition in terms. But it is good in that case only. The plea should go to the right of action, — • not to the question of damages.” Numerous authorities are cited sustaining the decision, and among them, those from 1 Saund. R. above quoted.
To apply the rule to this case. What is, in fact, the covenant, according to its right construction ? If it had stopped with the words “ determination of said partnership,” it would have been a covenant of indemnity merely. But the words “by assuming and paying the same when due,” constitute an important addition. They provide a special manner and time of indemnity ; — in effect, by acquitting and discharging the plaintiff from the copartnership liabilities as they should become due, and that “ in full.” These words are not mere surplusage, as the plea would, in fact, make them. The plaintiff'was not content with a general covenant to indemnify. He required that these “liabilities,” (for that is the word used,) should not hang over him; and so provided againstthis inconvenience by this portion of the covenant. It is obviously, therefore, a very material part of the covenant. In the second count of the declaration it is so treated and counted upon; and if the plea is good, this count is bad as going beyond the legal effect of the covenant. Suppose the covenant was that the covenantors would assume and pay the liabilities specified in full when due, and so, or thus, save *271harmless and indemnify the covenantee. Would the plea then meet it? Clearly not. And is not this the same in effect as such a covenant ? It is difficult to perceive any difference. The covenant is for indemnity by assumption and payment of the debts when due, and the breaches assigned in each count are coextensive with the covenant, embracing the assumption and payment. The plea goes only to the damages, and not to the assumption and payment ; and, consequently, the breaches alledged stand admitted, and give the right to a recovery. The demurrer must therefore be sustained.
No question as to the rule of damages is now presented.
The second question presented is, whether the motion of the defendant, Ring, for leave to plead his discharge in bankruptcy puis darrein continuance, ought to be granted.
It is objected by the plaintiff, that Ring having joined with Fitch in the other pleas going to the merits of the action, it is not now competent for him to plead a several plea, going to his personal discharge ; — that he cannot now sever at all, but must stand or fall by the issues already made in the cause. I have examined the cases cited by the plaintiff’s counsel, but I do not perceive that they reach the question. They establish the proposition, pretty fully, that where one defendant joins with others in pleading to the merits, he cannot also sever and plead a matter in personal discharge. But these are all cases of pleading originally, and none of them cases where a plea was tendered puis darrein continuance.
To determine this question, it is necessary to consider the rules regulating these pleas, and their effect. They are, as their name imports, of matters which have arisen subsequent to the former pleadings, and the last continuance of the cause, and which go to abate or bar the suit. As they tend to delay, great strictness is required in regard to them. They must be verified by oath; must be *272framed with great certainty; and but one of them can be pleaded. And, what is more material as to this question, by pleading one of these pleas, a defendant abandons all other pleas pleaded by him in the cause, and places the issue of the suit, as to him, entirely upon the single plea. A plea in abatement of this character may be pleaded, for a former plea was a waiver only of matters in abatement then existing. But upon such a plea too, the judgment, if against the party pleading it, is final, whether on a d emurrer, or on trial, and not of respondeos ouster. 2 Tidd’s Pr. 847, 850, ’1; 1 Chitt. PI. 635, ’6. The effect, then, of this plea, if received, is an abandonment by this defendant of the pleas formerly pleaded by him, and as respects him they are off the record; though they may stand as the several pleas of the other defendant, to the same effect as if he had pleaded them sole. The defendant pleading this plea, if it be received, will not therefore stand in the position of defending with the other defendant jointly on the merits, and severally in respect to his personal discharge, as would be the result in the cases referred to. And if a defendant, who has pleaded in chief, may abandon his plea so pleaded, and plead in abatement a matter subsequently arising, I see no reason why he may not so abandon a joint plea, and interpose a several plea of a discharge obtained subsequently. The other defendant is not prejudiced; the plaintiff may follow up the issue as against him; and if the defendant pleading the discharge succeed, a nolle prosequi may be entered in respect to him, or he may be discharged by the judgment of the Court, and the cause conducted to final judgment against the other defendants. 1 Chitt. PI. 32, 33, 41. I am therefore of the opinion that the motion should be granted.
Certified accordingly.
