¶1Defendant in this case was convicted of the crime of keeping and maintaining a common nuisance under the liquor laws of this state. During the trial of the action the state offered in evidence three bottles which it claimed contained beer and which it also claimed were purchased from the defendant as- charged .in the information. The case comes up on the judgment roll alone, so we do not know what the evidence was, but the record shows a plea of not guilty which put to issue all of the material allegations of the complaint, and both under the plea and the charge of the court it was necessary for the state to prove, and for the jury to find, that the contents of the bottles were actually beer.
¶2When the jury retired to deliberate on the verdict, the court sent to the jury room with the jury the three bottles with their contents, but it did not caution the jury not to open the said bottles or to experiment with them. No objection, however, seems to have been made by the defendant to the court’s action in this respect. When the bailiff was notified by the jurymen that they had arrived at their verdict, and when he opened the door of the jury room to obtain the same, he found the three bottles empty. His affidavit is as follows: “John Weeding, being first duly sworn on his oath, says that he was one of the bailiffs in regular attendance upon the special January, 1914, term of said district court, and that as such he was duly sworn as a bailiff to take charge of the jury impaneled and sworn to try the above-entitled action, upon their retirement for the consideration of their verdict; that, upon the retirement of said jury to the jury room, there was taken with said jury to the said jury room, among the exhibits introduced in evidence in said action, three bottles, commonly known as quart bottles, alleged by the state to contain an intoxicating liquor commonly known as beer, and that the said three bottles were left by the bailiffs in charge of said jury, in the jury room with the said jury during their deliberations upon their verdict. That upon his being notified by the said jury that they had arrived at their verdict, and upon the opening of the *399said jury room by the bailiff in charge of said jury, said affiant as one of said bailiffs discovered that the said three bottles had been opened by some of said jurymen, during their deliberations upon their verdict, and that he verily believes from his knowledge of the facts and from the statement made to him by the said jurymen thereafter, that the said contents of the said exhibits were drunk by certain of the jurymen impaneled and sworn to try said action during deliberations of the said jury upon their verdict, and while in their jury room for that purpose; and affiant further avers that the said bottles taken to the said jury room as aforesaid, and emptied of their contents as aforesaid, were taken empty into open court by the bailiffs in attendance upon said jury and when the said jury returned into open court to render their verdict.”
¶3If the jury drank the contents of the bottles in order to test its qualities as an intoxicant they clearly violated the law, as they had no right to try any such experiment. Consolidated Ice-Mach. Co. v. Trenton Hygeian Ice Co. (C. C.) 57 Fed. 898; People v. Conkling, 111 Cal. 627, 44 Pac. 314. Even if they drank it from a spirit of bravado, prejudice will be presumed.
¶4There is no merit in the contention of counsel for the state that in this case there was no proof that the contents of the bottles were drunk during the deliberations of the jury or before they had signed their verdict. The affidavit of the bailiff clearly shows that it was drunk before the jury notified him that they had arrived at a verdict, and their deliberations in the eyes of the law must be presumed to have continued not only up to such time, but up to the time that their verdict was returned in open court, and in fact until after the jury had been polled if a poll had been demanded. Up to this time, indeed, any juryman might have withdrawn his signature and repudiated his action. It is not even necessary to decide the case on the ground that the jury wrongfully experimented with the evidence. Both parties have a right to the cool, dispassionate, and unbiased judgment of eách juror, and the rule seems to be well established that prejudice will be presumed if liquor is drunk after the jury has retired to consider the case. State v. Baldy, 17 Iowa, 39; Berry v. Berry, 31 Iowa, 415; State v. Reilly, 108 Iowa, 735, 78 N. W. 680; State v. Bullard, 16 N. H. 139; People v. Douglass, 4 Cow. 36, 15 Am. Dec. 332 ; Rose v. Smith, 4 Cow. 1Y, *40015 Am. Dec. 331; Gamble v. State, 44 Fla. 429, 60 L.R.A. 547, 103 Am. St. Rep. 150, 33 So. 471, 1 Ann. Gas. 285, 12 Am. Crim. Rep. 638; Jones v. State, 13 Tex. 168, 62 Am. Dec. 550; Davis v. State, 35 Ind. 496, 9 Am. Rep. 760; Leighton v. Sargent, 31 N. H. 119, 64 Am. Dec. 328; Ryan v. Harrow, 27 Iowa, 494, 1 Am. Rep. 302; Dolan v. State, 40 Ark. 454; Creek v. State, 24 Ind. 151; State v. Bruce, 48 Iowa, 530, 30 Am. Rep. 403; State v. Madigan, 57 Minn. 425, 59 N. W. 490; State v. Greer, 22 W. Va. 800.
¶5We realize that some authorities hold that prejudice will not be presumed, but must be affirmatively shown. See 12 Oye. 726. We refuse to follow these cases, however, as it is very difficult for us to see how the defendant can generally, and especially where the misconduct takes place solely within the jury room, furnish the required proof. The rule is well established that a juryman will not be allowed to impeach his own verdict. Counsel for the defendant in the case at bar produced all the evidence that it was possible for him to obtain and to introduce. It would have been competent, it is true, for the state, the verdict having been once attacked, to have produced evidence in support thereof,' even though it came from the jurymen themselves, but this it failed to do. The presumption of prejudice, therefore, prevails, as there is no proof to overcome it.
¶6The judgment of the District Court is reversed and the cause is remanded for further proceedings according to law.
