delivered the opinion of the Court. The defendant moves to set aside the verdict in this case, on the ground of misdirection in point of law, by the judge who tried the action.
In actions on contracts, it is the undoubted right of a defendant to have all his joint promisors joined with him in the suit, and in the earlier reported cases the want of proper parties as defendants was held a good defence under the general issue, upon the ground of variance between the promise described in the declaration, and the proof offered in the case. But as such a defence was founded on matters more particularly within the knowledge of the defendant, and as in all joint contracts each one is liable to the plaintiff to the whole amount, whether the action be against him alone, or jointly with his co-promisors, with a view to avoid the evils that would result from repeated nonsuits on the same cause of action the rule was established, that the omission to include all the promisors was a defect in form merely, and could be taken advantage of only by plea in abatement.
The defendant so far adopted this rule as to present his defence by a plea in abatement, but under this plea he insists that he is not bound to give the plaintiff a perfect writ, or the means of making a perfect writ. He claims that it is sufficient for him to show that the w-rit, in its present form, is defective for want of proper parties ; and he has argued the question elaborately on the point, whether it is a universal rule that in a plea in abatement the defendant must give the plaintiff a better writ.
Although a leading distinction taken in the books between pleas in abatement and pleas in bar is, that the former goes only to the action in its present form, while the latter goes to the foundation of the action, yet it very clear that this distinction has not a universal application to these pleas.
*23There are many cases where a plea in abatement need not furnish the plaintiff with a better writ; as a plea that no such person exists as the plaintiff, a plea of non-tenure, or plea of disclaimer, and the like.
No authorities have been cited by the defendant to establish the position, that when the objection is really one of form and the defendant is bound to give a better writ, he is not required to point out the error and furnish the means for avoiding it in the further prosecution of the cause. The authorities are clearly the other way.
Lord Mansfield, in Rice v. Shute, 5 Burr. 2611, says a defence to an action for non-joinder of all the parties liable, “ must be taken in abatement, and the defendant must say who the partners were.” The case before him was a case of co-partners.
In 1 Esp. N. P. Digest (3d edit) 118, it is said, that where the defendant pleads in abatement the non-joinder of his partners, lie sets out all his partners and the plaintiff knows against whom to proceed.
The rule as stated by Mr. Gould, in his treatise on pleading, p. 254, is, that the plea must be so framed as to enable the plaintiff, in a subsequent suit for the same cause of action, to supply the defect or avoid the mistake.
In Stephen on Pleading, 435, it is said the meaning of the rule requiring that a plea in abatement should give the plaintiff a better writ, is, that in pleading a mistake in form, in abatement, the plea must correct the mistake, so as to enable the plaintiff to avoid the same objection in framing his new writ.
The case of Goodson v. Good, 6 Taunt. 587, is directly in point. It was there held, that a plea in abatement that the defendant jointly with sixteen others promised, imports that the defendant, jointly with sixteen others, and no more, promised, and if there were more the plea is disproved.
If the rule were not so, the benefits of a plea in abatement would be in a good degree lost. If the defendant should, in relation to those matters more pecul'arly within his own knowledge, be allowed to interpose a plea in abatement without furnishing the means to avoid the error in the further *24prosecution of the cause, it is obvious thai he might defeat the action for want of proper parties, as easily and as-repeatedly under this plea, as he could do, if this objection might be taken under the general issue.
Such is not the policy of the law, and such have not been the adjudications on this question. By the rules of law, it was the duty of the defendant, "by his plea, to furnish the plaintiff with the means of correcting the defect in his writ. That defect was the omission of the names of some of the joint promisors. If the plea in abatement which professed to remedy that defect, omitted to furnish the names of all who were members of the joint stock company sued, or if it included among those named in it an individual who was not a joint promisor, the plea was not sustained upon the evidence.
It was suggested by the defendant, that the statute of 1836, c. 273, abolishing special pleading, had extended the grounds of defence under this plea ; but it is very, apparem ¡rom the phraseology of the statute, that its provisions apply only to pleas in bar, and not to pleas in abatement.
But the defendant further contends, that the plaintiffs were estopped to deny that the persons named in the plea in abatement were not the joint promisors, as named in that plea, by-reason of their own proceedings pending the action. Fie claims that the plaintiffs, by procuring an amendment of their writ, summoning the persons named in the plea, and filing a new declaration including them as joint promisors, have confessed the truth of the plea, on the record.
It is difficult to perceive how any greater effect could be given to this proceeding, than would be in the case of an original writ against several defendants, which had been amended by striking out the name of one of them. In such a case it certainly would not be contended, that the plaintiff would be estopped from showing that the promise was made only by those retained in his writ. The plaintiff may act under a mistake, and in a case like the present, may have 'been misled by the defendant, but discovering his error, he places his declaration on correct premises. To give effect -to the principle claimed by the defendant, would be sub*25stantially to abrogate the whole doctrine of amendments, and as well in reference to the nature of the contract declared upon, as in reference to the parties to that contract. It would deprive the parly of the benefit of the provisions of the statute allowing new parties to be added, if he is to be estopped by his previous pleadings. It was properly ruled at the trial, that the plaintiffs were not estopped from denying the truth of the facts set forth n the plea in abatement, and that the amendment they had infvluced into their writ and declaration was at most only evidence to be laid before the jury for their consideration.
