¶1This action was on a bond given pursuant to section 2912 of the Code of Civil Procedure, and the sole issue was whether the defendant Eika Bernhardt, the principal, was the general owner of certain chattels transferred to her under a bill of sale from her husband. The plaintiff, in his efforts to overcome the proof of her title, introduced the evidence of two witnesses, Adolph Mendel and Julius Kaufman, the original owners of the claim which was the foundation of this suit and which the plaintiff had acquired through an intermediate assignment. On *653cross-examination each of those witnesses was interrogated as to his pecuniary interest in the result of the action. The evidence was excluded and exceptions were duly taken. These rulings constituted error prejudicial to the defendants.
¶2The interest which a witness has in the subject of the contro- ■ versy is always a material inquiry. 1 Greenl. Ev., § 446; Matter of Snelling, 136 N. Y. 515, 519; Vaughn v. Westover, 2 Hun, 43. The utility of cross-examination aimed at the credibility of a witness is seriously impaired, if inquiry into his relation to the subject-matter of the litigation be restricted. The plaintiff’s recovery in this action depended largely on the testimony of these two witnesses, who gave evidence of admissions adverse to the defendants’ contention. Their disinterestedness, therefore, especially when considered in the light of the slight proof attacking the bona fides of the transfer, became of material moment.
