upon the part of the plaintiff, the objection was overruled, and an •exception was taken. It seems to have been held, at the instiga-' tion of the defendants, in repeated cases in the court of appeals (Roberts v. N. Y. E. Railroad Co.,
128 N. Y. 455 ; 40 St. Rep. 454 ; McGean v. Man. Railway Co.,
117 N. Y. 219 ; 27 St. Rep. 337 ), that such evidence is incompetent and improper, because itt leaves the witness to determine the only question which the court is called upon to decide upon the evidence. The court said, in the case of
Ferguson v. Hubbell, 97 N. Y. 507 , that it is generally safer to take the judgment of unskilled jurors than the opinions of hired, and generally biased, experts. In the ease of McGean v. Railway Co., above cited, the question was asked, “ What would have been the rental value of the premises in the years 1878, 1880 .-and 1881, if the railroad had not been built ?
" And it was held to be improper, because it was merely speculative, and speculative upon the only question which the court and jury were.called upon to decide, and the question called for an opinion of the witness upon that very subject; the court saying that the case was one where the facts which formed the basis of the action could be specified, and should be stated, and the inference to be drawn from those facts should be drawn by the court and the jury. So, in the case at bar, the witness was asked, in substance, what effect the construction of the elevated road had upon the value of the premises,—the very question which the court was called upon to determine from the evidence of the facts relating to the property. The same rule was laid down in the case of Hunter v. Man. Railway Co.,
141 N. Y. 281 ; 57 St. Rep. 400 , where it was held improper to show what is the particular damage caused to the plaintiff by the presence of the railroad, or to show what the premises would be worth, or what their rental value would be without the ■road; the court holding questions of this latter class to be an in-’ vasion of the province of the court and the jury, and that the rule, ■as now laid down, rigidly excludes calling for the judgment of the witness upon the question which is to be submitted and decided. The sole question involved in the investigation in the case at bar was whether the construction of the road had tended to increase ■or decrease the value of the property in question, and this, under the decisions, the court was called upon to decide, and not the witness.
The judgment should be reversed, and a new trial ordered, with «costs to the appellant to abide the event.
All concur.
