¶1In the district court of Fillmore county, Henry Biester was charged with a felonious assault and was tried and found guilty of an assault and battery. The court overruled a motion for a new trial and sentenced defendant to pay a fine of $50 and the costs of prosecution. The clerk of the court, acting on the suggestion of the trial judge, taxed against the state the fees and mileage of *278twenty-three witnesses, who had been subpoenaed by the state, bnt not called or examined at the trial. The aggregate amount of such fees and mileage is $192.70. The county attorney moved to retax these costs, and in support of the motion filed affidavits from which it appears that seven of the twenty-three witnesses were never intended to be used to prove the criminal act upon which the prosecution was grounded. They knew nothing about the alleged assault and could give no testimony tending in any degree to establish the commission of a misdemeanor. They were subpoenaed only for the purpose of rebutting any evidence that might be adduced to show that the protracted illness of Henry Nachbor, the prosecuting witness, was due in part to bad nursing. The sixteen other witnesses constituted the state’s reserve. They did not testify because the emergency in which they would be available did not arise. They were intended to be used for the purpose of meeting evidence which there was reason to suppose the defendant Avould offer to prove his general good character. Acting, it would seem, on the assumption that all costs made by the state, whether necessary or unnecessary, reasonable or unreasonable, should be taxed against the defendant, the trial court sustained the motion.
¶2We can not approve the decision nor the principle upon Avhich it is based. , The fees and mileage of the seven witnesses subpoenaed for the purpose of proving that the assault was felonious should not have been charged against the defendant, for upon that issue the state failed. There is, it seems to us, neither reason nor justice in imposing on a person who has committed a misdemeanor the expense incurred by the state in a futile effort to convict him of a felony. The costs of prosecution contemplated by the statute are in our judgment, the costs incurred in establishing guilt, in proving a specific charge, not those made in connection with a false accusation — a charge that is disproved and shown to be groundless. If the seven witnesses had been actually called and sworn they could have given no testimony releArant to the issue resolved in favor of the *279state; they could have contributed nothing whatever to the result of the trial. The expense incurred in bringing them to court was unnecessarily incurred; it was, according to the verdict, which is a legal verity, incurred in attempting to prove what was not true. Adjudged cases bearing directly upon the point are not at hand, but Commonwealth v. Ewers, 4 Gray [Mass.], 21, and State v. O’Kane, 23 Kan., 244, may be cited as sustaining in a general way the principle upon which our conclusion rests.
¶3The facts found by the trial court make it certain, regardless of the general rule in such cases, that the county attorney had good reason for subpoenaing witnesses to prove that the defendant Avas of bad repute in the neighborhood where he lived. Biester’s character was not necessarily involved in the issue; it was presumed to be good, but he was not required to rely on the presumption; he was at liberty to buttress it with evidence. Such evidence the state had, however, a right to contradict; but from the record before us, we can not believe that the county attorney acted with common prudence or discretion in summoning sixteen impeaching witnesses. Costs properly taxable to a defendant in a criminal cause are not all the costs which the person having charge of the prosecution may see fit to make, but only such as there was actual, apparent, or probable necessity for incurring. In determining AArha,t costs fall Avithin this description, the trial court has, of course, a very large discretion, but its decision is nevertheless subject to review, and will be reversed or modified Avhenever it appears that there has been an abuse of the discretionary power. In this case the action of the court Avas based on a Avrong principle. The fees and mileage of the sixteen witnesses were evidently taxed against the defendant because they had been subpoenaed and were in attendance, not because they Avere all supposed to be necessary for the purpose of impeachment. Trial courts usually limit the number of witnesses that may be called to prove facts collateral to the main issue; and we presume this discretionary poAver would have been exercised in this case *280if defendant’s character bad been actually drawn in question. An order imposing a reasonable limitation should have been anticipated by the county attorney. He should not, we think, have subpoenaed mure than seven impeaching witnesses. Nothing in the record discloses an apparent or probable necessity for m'ore than that number. Our conclusion, therefore, is that the fees and mileage of sixteen of the twenty-three witnesses were improperly taxed against the defendant Ried v. State, 19 Nebr., 695; Mergentheim v. State, 107 Ind., 567; Minthon v. Lewis, 78 Ia., 620.
¶4The order under review is reversed and the case remanded with direction to the district court to retax the costs in conformity with the views here expressed.
¶5Reversed and remanded.
