This is a prosecution for bastardy. Tbe evidence is very similar to that which is common in such cases. The mother, as the main witness for the state, testified positively that the defendant was the father of her child,
(1) The mother and the defendant are not of equal credibility. The mother is a mere witness for the state in a proceeding to compel the father of her child to support it, and save the town from such a burden. She has no pecuniary interest, beyond that of any other witness, in the result of the prosecution. Before the statute allowed a party to testify in his own behalf he was excluded from being a witness on the ground of his pecuniary interest in the result; while the mother in such a case was not excluded on that ground, or any other, but was always a competent witness. She is an involuntary witness, and may be compelled to testify, and he is not; but he may testify, and his pecuniary interest in the result now only goes to his credibility. ' It would be highly improper for the court to submit to the jury the question of their equal credibility as witnesses when, from the nature of the prosecution, they are not and cannot be equally credible. But even in case where both Avitnesses are the parties, and equally credible, in a civil suit, or where the verdict.may depend upon the preponderance of the evidence, such an instruction has been held by this court to be improper, in Bierbach v. Goodyear Rubber Co. 54 Wis. 208, Avhich has been followed in Spensley v. Lancashire Ins. Co. 62 Wis. 443. The reason given for the rejection of such a rule is
(2) The instruction assumes that, if the defendant and complainant are of equal credibility, then there can be no verdict of guilty unless further evideuce or circumstances proven satisfy the jury beyond a reasonable doubt of the defendant’s guilt; that is, such further evidence, without 'that of the complainant, must so satisfy the jury,— the corroborating evidence must in itself be sufficient without the evidence to be corroborated.
The other instructions asked are abstract or self-evident propositions, or were in substance given in the general charge. We are unable to find any just cause of complaint in the general charge of the court, or to understand the reasons attempted to be given in the brief of the learned counsel of the defendant why it was not in all particulars correct and fair. The main burden of the argument seems to be that the testimony of the complainant was contradictory, incredible, and uncorroborated, and was insufficient to convict the defendant. We think that her testimony was strongly corroborated. She was a young, hard-working, unsophisticated Polish emigrant girl, probably ignorant and unacquainted with the ways or the laws of this country, or the effect of evidence. She would not be at all likely to ’become a willing or swift witness against an innocent man. Cold, wilful, and corrupt perjury would not bo likely to reside in the tender and untutored nature of such a young giii. She seems to have manifested no hatred or ill will or spirit of revenge against the defendant, and she makes no complaint of being seduced under a promise of marriage.
By the Court.— The judgment of the circuit court is affirmed.
