#### Harris Linden, Respondent, *v.*Samuel Brustein, Appellant.

(Supreme Court, Appellate Term,

June, 1898.)

1. Right to sue — The defendant cannot inquire into the terms of the plaintiff's assignment.

Where a party sues under an assignment of a cause of action, which is valid as against his assignor, the defendant has no legal interest to inquire whether the transfer was an actual sale, or merely colorable, or whether there was any consideration paid/ therefor, or what was the arrangement or understanding between the assignor and assignee. respecting the ultimate disposition of the proceeds of the recovery.

3. Witness — Impeachment.

Where, after the credibility of the plaintiff’s assignor has been attacked by two witnesses, the defendant calls the assignors as his own witness, he cannot subsequently insist that he has been injured by the refusal of the court to permit him to swear a third witness in order to impeach the assignor.

Appeal from a judgment of the Second District Court in favor of the plaintiff.

A. H. Sarasohn, for appellant.

John Callahan, for respondent.

Gildersleeve, J.

The ^ action is for a conversion, and the defense is a general denial, payment and an allegation that plaintiff is not the real party in interest. The plaintiff is the assignee of one . Simon Bririn. The Code, section 449, requires every action to be prosecuted in the name of the real party in interest; but the rule *656is that a plaintiff, suing upon an .assigned claim, “ is the real party in interest, under the Code, if he had a valid transfer as against the assignor, and holds the legal title to the demand; and the defendant has no legal interest to inquire whether the transfer was an actual sale or merely colorable, or whether a consideration was paid therefor. While such an inquiry may become material, if the rights of creditors are involved, or when some defense or counterclaim against the assignor is sought to ibe. interposed, it constitutes-no defense on the ground that the plaintiff is not the real party in interest.” See Sheridan v. Mayor, 68 N. Y. 30. The assignment from Brinn to plaintiff was after the cause of action for the conversion had accrued, and the assignment transferred the title of Brinn to the property as well as to the cause of action. The plaintiff could maintain the action, and the consideration of the assignment was not material, so long as it was valid as between, the parties to it. See McKeage v. Hanover Fire Ins. Co., 81 N. Y. 38. We do not think that there was reversible error in the refusal of the court to allow defendant’s counsel to ask Brinn, on cross-examination, the following questions, *“*Q; Then did you take out the summons? Who paid for the summons in this case, you or Linden? ” or the other similar questions referred to in the brief of the appellant. It is true that the court might well have .allowed them, were.it only with a view of tending to discredit Brinn’s testimony by showing that he had an interest in the result of the action; but the refusal to do so, in view of all the testimony in the case, does not constitute such’ prejudicial error as to warrant us in reversing the judgment. Brinn gives the details concerning the assignment. He says, “I told Linden that I had ;a. claim against Brustéin; and as I live uptown, there is too much trouble for m|e to sue him in my District Gourt, and he wants to buy this claim of me, that he should buy it, and sue him in this court.’’ Q. “What did Linden say?” A. “He was satisfied; he said all right.” He swears the assignment was made, before the commencement of the action, at No. 57 Bayard street, in the house of Linden. There seems to be no doubt that the assignment was valid as against the assignor, and, as -we-have said, ‘the defendant has no legal interest to inquire whether the transfer was an actual sale :or only colorable, or whether there was any consideration paid therefor (see Sheridan v. Mayor, *supra),*or what was the arrangement or understanding, between the parties respecting the ultimate disposition of the proceeds of the recovery. See Moore v. Robertson, *25*Abb. N C. 173. The evidence is meagre and unsatisfactory in many important respects, but we think *657there is enough to warrant a finding of the facts above set forth. The plaintiff’s assignor, Brinn, swears that, on December 18, 1896, defendant bought $64.93 of him “ on memorandum,” with the understanding that if the goods were not paid for they were to be returned; that the goods were not paid for; that he demanded their return, and that they were never returned, or paid for. Defendant admits that he owes plaintiff, or his .assignor, $10 and some cents; but he claims that he had either paid for the rest, or returned the goods. He also denies that he ever bought as much as $64.93 of Brinn at any one time. On his cross-examination, Brinn is unable, apparently, to give the 'details of the bill of ,goods sold “ on memorandum,” to defendant, without recourse to his books for the purpose of refreshing his memory, and ,hs merely says that the goods consisted of cloth. He, however, has furnished ,a bill of particulars, which is annexed to the return,' and which gives the details. As we have said, the testimony leaves much to be desired as to definiteness and clearness in many important particulars, but there appears to be sufficient evidence tO' sustain the finding of the trial justice in plaintiff’s favor. With regard to the point made under the amended ¡return, that the justice refused to allow the defendant to put a witness on the stand for the purpose of impeaching the plaintiff’s assignor, Simon Brinn, we may say, the defendant had produced two witnesses, who were examined solely for the purpose of attacking the credibility of Brinn, and had called a third witness for the same purpose, when the justice refused to allow such witness to be sworn or examined, to which the attorney for defendant excepted. The defendant’s attorney thereupn called Simon Brinn, as a witness on behalf of the defendant, and examined him at length with respect to the merits of the action. This course appears to have been entirely inconsistent with the position which he had taken with respect to Brinn’s credibility. By so doing, he gave him credit with the court, and precluded himself from following up the attack which he had made, and which, by his own act, he had in effect abandoned.

We do not find errors in the rulings of the justice, as to the admission and 'exclusion of evidence, of sufficient magnitude to require a reversal. It follows that the judgment, so far as assailed on this appeal, should be affirmed, with costs.

Beekmah, P. J., and Giegerich, J., concur.

■Judgment affirmed, with costs.
