Although the assignment to Knowles was eventually avoided by the subsequent proceedings in bankruptcy against the estate of the assignor, the Charles A. Jenkins Company, hereinafter called the corporation, yet at the time of the alleged conversion he, and he alone, had the legal title to the *569property, the right to immediate possession and the actual possession. The corporation by the assignment had parted with the legal title and with it all right to the immediate possession.
Under these circumstances Knowles as assignee brought in the municipal court this action of trover. Before the trial in that court and within four months from the recording of the assignment, a petition was filed in the bankruptcy court against the corporation, upon which such proceedings were had as that the corporation was adjudicated a bankrupt and Bacon was appointed trustee; and he as such trustee filed in the municipal court a motion that “ he be admitted as party plaintiff in the above case and be allowed to prosecute said case,” which motion was granted. The record speaks of this motion as one “ substituting ” Henry C. Bacon “ the trustee in bankruptcy ... as plaintiff in the place of Knowles,” and inasmuch as all parties, including the justice of the Superior Court upon whose report the case is now before us, have proceeded upon the theory that the order allowing the motion was a substitution of Bacon for Knowles as plaintiff, we shall first consider it on that theory.
The main question is whether this action can be maintained by him as the substituted plaintiff. Before proceeding with this inquiry it is to. be noted that the question is not whether he could not now as trustee maintain some kind of action in the case, even in the nature of trover against the defendant, nor even whether as the person having the beneficial interest in the proceeds of the suit he could not have been allowed to prosecute this suit in the name of the original plaintiff. Even if it be assumed that the right to recover either the specific property or its proceeds from the defendant became vested in the trustee, still when he attempts to prosecute that right in a State court he is bound by the rules 6f procedure therein established; and accordingly they must govern the same as when any other party invokes the jurisdiction of the court. Even the provision of the bankruptcy act (§ 11 b), that the trustee may be ordered to enter his appearance and defend any pending suit against the bankrupt, cannot be regarded as intended to regulate the practice of the State courts and require them to make the trustee a party on his application, but rather to place upon him the official duty to appear according to the rules and practice of those respective *570courts so as to protect the interests of the general creditors. National Distilling Co. v. Seidel, 103 Wis. 489. Bank of Commerce v. Elliott, 109 Wis. 648. See also Collier on Bankruptcy, (7th ed.) 223, 224.
The present action is trover. It is elementary that at common law the plaintiff, in order to support this action, must at the time of the conversion have had a complete property either general or special in the chattel and also the actual possession, or the right to the immediate possession of it. Chitty on Pl. 167, and cases cited in the notes on that page. And such always has been the law in this State, both before and since the practice act. Vincent v. Cornell, 13 Pick. 294. Newhall v. Kingsbury, 131 Mass. 445. Robinson v. Bird, 158 Mass. 357. Winship v. Neale, 10 Gray, 382. And the plaintiff must show that at the date of the writ he had the right to immediate possession. Newhall v. Kingsbury, ubi supra, and cases cited. If there be an outstanding special property in another so that the genera] owner has not the right to immediate possession, then the latter should sue in case for the injury to his reversion, not in trover for the value of his goods. Chitty on Pl. 167.
Now it is apparent that when the conversion occurred for which this action was brought, the only person who had the possession and the right of possession was the assignee, the original plaintiff. It is true that his title was liable to be avoided by bankruptcy proceedings, but until so avoided it stood as against all persons. And such was the situation at the time the writ issued. Neither at the time of the conversion nor of the bringing of the action had the trustee any right to the possession. Nor did he succeed anybody who at either of those times had the right. He could not prosecute the right of the bankrupt because the bankrupt had no Such right, nor -could he prosecute as the successor of the assignee, because he did not hold under the assignee but under the bankrupt and adversely to the assignee. The action was brought for injury to the right of the assignee. The trustee attempts to prosecute it for injury to the right of the bankrupt, another and distinctly different right. For these reasons also the case is not analogous to those cases where an executor or administrator may come in and prosecute an action begun by the deceased. Even if it be said *571that the title of the trustee related back to the time of the assignment, still the same trouble remains. As substitute plaintiff he is trying to maintain an action which is not based upon any right of possession that the bankrupt had either at the time of the conversion or at the date of the writ, because the bankrupt had no such right, nor upon the right of the assignee because he in no sense claims under or in continuance of the right of the assignee, but upon his own right of immediate possession as trustee at the time of the conversion and at the date of the writ. He failed to prove any such right in himself either by relation, succession or otherwise, and therefore, under our rules of procedure, failed to maintain his action. At least the first and sixth rulings requested should have been given.
So far this opinion has proceeded upon the theory upon which the judge and counsel have proceeded, namely, that the motion was in legal effect a motion to strike out the name of Knowles as plaintiff and to insert in place thereof the name of Bacon, and that after the motion was allowed the only plaintiff on record or otherwise was Bacon. It is to be observed however that the motion does not expressly ask to have the name of Bacon substituted for that of Knowles, and is not in the usual technical form of a motion framed for such a purpose. The language is somewhat equivocal, and, by a liberal but not impossible construction, under the circumstances of the case it might have been held by the trial court to be a motion to be allowed to prosecute the case in the only way possible, to wit, as the only party plaintiff really beneficially interested, and in the name of the original plaintiff. See Costelo v. Crowell, 134 Mass. 280.
The assignor having been adjudged a bankrupt upon a petition filed “ against it within four months after the recording of the assignment,” Knowles, the assignee, by the express terms of the assignment as well as by law, was bound to pay over to Bacon, the trustee in bankruptcy, the proceeds of the suit. The real party beneficially interested therefore was Bacon, not Knowles; and had the motion been regarded as a motion that the trustee, as the party entitled to the proceeds and therefore the only one beneficially interested, should be allowed to prosecute the action in the name of the original plaintiff for the benefit of the trustee, the point now relied upon by the defendant could not have been *572taken. The plaintiff Bacon has acquiesced in the interpretation of his motion as one of substitution, however, and cannot now contend to the contrary.
But the point is very technical, and so far as appears upon this record has no relation whatever to the real merits of the case. The record shows a conversion, an action brought for damages by the person entitled to bring it, and the intervention of a party beneficially interested in the proceeds; and the failure of the latter to get at the proceeds is based, as before stated, on a mere technicality which can be cured by amendment. In view of all the facts appearing upon the record we think that the plaintiff should have an opportunity to apply to the Superior Court for leave to amend his writ in the manner hereinbefore indicated.
If within thirty days from the entry of the rescript no amendment is allowed changing the position of the trustee to that allowing him as the party beneficially interested to prosecute the action in the name of the original plaintiff, there shall be judgment for the defendant. If, however, the amendment be allowed, then such proceedings thereafter shall be had either by way of a judgment upon the verdict, or of a new trial, or otherwise, as to that court shall seem just and proper.
So ordered.
