This is a bill in equity for the redemption of a mortgage on real estate, made by Staples, one of the defendants, to one Crosby. The plaintiff claims the right of redemption, by virtue of an attachment and execution thereon *261against Staples, and by a sale thereof by the officer, according to the Rev. Sts. c. 73, <§> 38.
Staples demurs to the bill; and the other defendant has filed an answer, alleging certain facts, on which he prays that other persons may be made parties. The first cause of demurrer is, that the plaintiff has not stated a case which entitles him to relief in a court of equity. But there is no ground for this objection, unless the second cause of demurrer be well founded. That cause of demurrer is, that the bill is founded upon and contains a direct charge of fraud and conspiracy, of which this court, as a court of equity, has no jurisdiction. It is true, that the bill charges the defendant Staples with having made a fraudulent assignment of the bond of defeasance, after the plaintiff’s attachment of the right of redemption. And it is also true, that, as a court of equity, we have no jurisdiction in cases of fraud, where relief against fraud is the direct and sole object of the bill.
But where we have jurisdiction, and a question of fraud is incidentally-involved, we have power, necessarily, to inquire into and decide such question ; otherwise the jurisdiction expressly given by the statute might be eluded. So it was decided in Holland v. Cruft, 20 Pick. 321. That was a case founded on an. alleged trust, and averring a fraudulent assignment to defeat the trust, and praying that the assignment might be set aside on account of the fraud. And it was held, that, although the court could not have equity jurisdiction, in the case of a bill to set aside a contract on the ground of fraud, yet that it had jurisdiction of that bill, inasmuch as it sought the performance of a trust, and the question of fraud must necessarily be considered and decided, as collateral and incidental to the principal inquiry. “ In the exercise of this jurisdiction,” the chief justice justly remarks, (p. 326,) “ every question, whether of law or fact, upon which the rights of the parties depend, of whatever nature or character, must be inquired into and decided, according to the established course of proceedings in courts gí equity.” That this case was decided on just and un« *262questionable principles, we can have no doubt, and they are conclusive in support of the present bill.
The bill prays for a discharge of the mortgage, and a reconveyance of the premises to the plaintiff, and alleges that a fraudulent assignment has been made, for the purpose of vesting an absolute estate in Crosby, the mortgagee, under whom the defendant Cutler claims title. That we have full power and are bound to inquire into and to decide upon the truth of this averment, appears to the court very clear. But the principal cause of demurrer, relied on in the argument, is, that Staples ought not to have been made a party. He, it is contended, has no interest in the premises, having conveyed his right and title to Cutler, the other defendant.
The general rule is, that a person who has no interest, and is a mere witness, against whom there could be no relief, ought not to be made a party. But there are exceptions to the general rule. A secretary of a corporation may be joined as a party, although he might be examined as a witness, and against the plaintiff could have no relief. So, agents to sell and auctioneers have been made parties, although no relief was prayed for against them. So, by the cases cited in 7 Yes. 287, and in 1 Yes. & Bea. 548, it seems to be left doubtful, whether a person, against whom no relief can be decreed, may not be joined as a party for the purpose of discovery. Lord Redesdale says, “that a bankrupt, made a party to a bill against his assignees, touching his estate, may demur to the relief, all his interest bein'g transferred to his assignees; but it seems to be generally understood, that if any discovery is sought of his acts before he became a bankrupt, he must answer to that part of the bill for the sake of discovery, and to assist the plaintiff in obtaining proof. 1 Yes. & Bea. 548. And we are inclined to this opinion in the present case, which is confirmed by taking into consideration the Rev. Sts. c. 107, $ 8. That section provides, that the action (to foreclose) may be brought in the same manner as a writ of entry, against whoever is tenant of the freehold ; and the mortgagor may, in all cases, be joined as a defendant, whether he then *263has any estate in the premises or not; but ire shall not be liable for any costs, when he has no estate in the premises and makes no defence to the suit.” The principle on which that section is founded seems to apply more strongly t) a bill for redemption than to an action to foreclose, inasmuch as in the former case the plaintiff may be entitled to a discovery. Upon the whole, therefore, we are of opinion that Staples is rightfully joined as a party, and the demurrer must be overruled.
As to the answer of the other defendant, alleging that he has made two mortgages of the premises, one to John Bacon and Nathaniel C. Cutler, and another to Hannah Paine, and which mortgages have never been paid or assigned, we think it very clear, the facts being admitted, that these mortgagees should be made parties. It is a case within the general rule that all persons materially interested in the subject of the suit ought to be made parties, to prevent further litigation, and so that the court may be enabled to do complete justice, by deciding upon and settling the rights of all persons interested.
In the present case, neither of the defendants has the legal title; the legal estate is vested in John Bacon and Nathaniel C. Cutler, to whom the defendant Thomas C. Cutler mortgaged the premises, long before this bill was filed. And, unquestionably, they must be made parties; for they are entitled to the redemption money, and not the defendant Thomas C. Cutler. So Hannah Paine must be made a party; and the question will be, whether the plaintiff will be entitled to redeem, without paying the full amount due on these two mortgages; provided the same were taken in good faith, and without any knowledge of the alleged fraud. However that may be, it is clear, that they must be made parties, so as to allow them an opportunity to defend their rights in the present suit.
