The Chancellor :—If the petitioner had shown any authority to prosecute the action of trover against Healy, in the name of Chase, the injunction would not be permit*198ted to affect Ms rights, without making him a party to the hill. (Nugent v. Smith, Moseley’s R. 354.) The assignee of a chose in action may sue at law in the name of the assignor ;[1] and in such cases, the assignee must be made a party to a bill for an injunction to stay the suit at law, or the court will permit Mm to proceed in the name of the assignor.[2] In this case, if the notes were assigned before *200the conversion, the assignee would have a right to maintain' the action of trover in his own name, but could not recover in the name of the assignor, who had no interest in the notes at the time of the conversion, and therefore could not be injured thereby. If the notes had been delivered up and cancelled before the assignment, so that Chase had no remedy thereon, but had a good cause of action against Healy for the conversion, the simple assignment of the notes would not authorize the assignee to prosecute in the name of Chase for the previous tort.
If the petitioner has any remedy, it must be either by an action at law, in the name of Chase and wife against Whitney *to recover the amount of the original notes, or by an action of trover, in his own name against Healy, for a conversion subsequent to the assignment, or by a bill in equity against all the parties, to obtain the possession or proceeds of the new notes, to which, perhaps, he may in equity be entitled, subject to the wife’s equity.
Under the circumstances disclosed in the petition, the suit at law must be considered as an action brought by Chase in his own right, or brought by the petitioner in his name, ivithout right or authority.
The motion to dissolve the injunction is refused, with costs to be paid by the petitioner.
Courts of law, in this state, under sec. 111, New York Code, have adopted the Chancery practice, as to parties, with a few slight modifications, per Mason, J., in Wallace v. Eaton, 5 How. Pr. R. 99, 100, and per Parker, J., in Hollenbeck v. Van Valkenburgh, id. 281, 284. Every action at law must now be prosecuted in the name of the real parties in interest. But an executor or administrator, or a trustee of an express trust, or person expressly authorized by statute, may sue, without joining with him the person for whose benefit the action is prosecuted. (Secs. 111, 113.) Previously an action at law, to recover chose in action, should be in the name of the assignor, or if dead, bis personal representative, if any; but if there was no executor or administrator, the assignee might sue in Ms own name. 2 R. S. (2d ed.) 274, sec. 5; Seeley v. Seeley, 2 Hill, 496; See Corbin v. Emerson, 10 Leigh, 663; Bell v. Shrock, 2 B.Mon. 29.
In equity, parties to a suit may be classed under three heads:
1st. Those who may be parties.
2d. Those who should be parties.
3d. Those who must be parties.
Those who may be parties.—Are those who have no real or legal interest, and who, without being improper, are not necessary parties; as for example, the assignor of an absolute and Voluntary assignment of a judgment, or an equity of redemption. Beeren v. Crane, 1 Green, Ch. R. 348; Vreeland v. Loubot, ib. 104, 348; Chester v. King, id. 405. Or, where a person implicated in a fraud, is made a party, for the purpose of charging him with costs, if M'Closker v. Brady, 1 Barb. Ch. R. 343; S. C., 1 Comst. 214. Or a residuary legatee to a bill by a creditor seeking to charge the general assets of the testator. Burrwell v. Corwood, 2 How. U. S. 515. But in general no one should be a party, against whom no judgment could be rendered. Reemsdyke v. Kane, 1 Call. 383; Vanderpool v. Devenport's Ex'rs, 2 Green, C. R. Where, however, the assignment is involuntary, as if made by operation of law, the assignor must be made a party. Sedgwick v. Cleveland, 7 Paige, 289; Mills v. Hoag, id. 21.
Those who should be parties.—The exact difference between those who may be, and those who should be parties, is slight, and the line of demarcation *200often difficult to trace. It is said that it may be done by limiting the class of those who should be parties, to those who have an interest in the event of the suit. Wiser v. Blackley, 1 John. Ch. 438; King v. Berny’s Ex'rs, 2 Green. Ch. 52; Caldwell v. Taggart, 4 Pet. 190; Bank Alexandria v. Seaton, 1 id. 306; Marshall v. Beverly, 5 Wheat. 313; Wendell v. Van Rensselaer, 1 John. Ch. 349; Hallett v. Hallett, 2 Paige, 15; see also Am. Ch. Dig. by Waterman, tit. Parties.
Those who must he parties.—Includes, as a general thing, those who should, he parties, and extends to all persons materially interested, in the matter of the bill, as plaintiffs or defendants. Such persons should be made parties, however numerous they be. West v. Randell, 2 Mason, 181; Crocker v. Higgins, 7 Conn. 342; Wendell v. Van Rensselaer, 1 John. Ch. 349; New London Bank v. Lee, 11 Conn. 112. The rule as to those who should be parties, is extremely pliable, and maybe moulded to suit the ends of justice. Hallett v. Hallett, 2 Paige, 15, and cases there cited. But the court will not exercise such latitude of discretion, wdien the rights of persons not before it, are so inseparably connected with the claims of the parties litigant, that no decree can be made without affecting the rights of the former.
