After careful examination of the testimony given on the trial touching on the question of the mental capacity of Holman Boorman when he made the exchange of certificates, we are entirely satisfied that the trial judge was right in holding that there was no testimony to go to the jury which tended to prove him mentally incompetent to make á valid exchange. The question was not whether he at some time had a delusion upon some subject, nor yet whether he always reasoned wisely or prudently, but, “ when capacity to do a certain act is in issue, the question is whether the alleged insane person had sufficient mental ability to know what he was doing and the nature of the act done.” Burnham v. Mitchell, 34 Wis. 117. “ The law recognizes the fact that there may be derangement of mind as to particular subjects, and yet capacity to act on other subjects. . . . The proof which is necessary to invalidate a man’s act by reason of his insanity must show inability to exercise reasonable judgment in regard to such act? Busw.
There was evidence given by a witness that he worked with Boorman a few days, cutting ice, in February before his death, and that deceased became quarrelsome and got mad at the witness because, as he said, witness did not drive the horse straight while he (Boorman) was holding the ice plow. On the strength of this testimony the plaintiff’s counsel proposed to ask him whether, in his judgment, Boorman was of sound mind at the time. An objection to this question was sustained on the ground that the witness had not shown enough facts upon which to predicate an opinion as to insanity, and this ruling is alleged as error. We think the ruling was right. It is the province of the court, in the exercise of a wise, legal discretion, to decide whether the facts on which a nonexpert’s opinion as to a person’s sanity is based entitle him to express his opinion to the jury. Denning v. Butcher (Iowa), 59 N. W. Rep. 69. This must be so, otherwise a nonexpert, after detailing the most trivial circumstance) might state his opinion as to sanity or insanity of the person whose sanity was in question. Such a rule could not be endured. In this instance the trial court rightly exercised its discretion.
This action is brought to recover upon the first or original certificate, and, it appearing that there was a valid surrender of that certificate or contract and acceptance of a different contract, the court was entirely right in directing a verdict for the defendant.
By the Oourt.— Judgment affirmed.
