II. There was a question regarding the good faith of the prosecutor in instituting and pressing these proceedings, and the trial court instructed as follows:
You are further instructed that it is improper to use the criminal laws of the State for the purpose of serving private ends; and in this connection you are advised that, in determining the guilt or innocence of the defendant, you are at liberty to consider whether the prosecution is conducted for the purpose of vindicating the criminal laws of the State, or for the collection of a debt claimed to be due from the defendant to the prosecuting witness, Albert liarrah.
Of course, the motive of the prosecuting witness, or of any other witness for that matter, may be shown for the purpose of testing his credibility, etc.; but the guilt or innocence of one accused of crime does not depend primarily upon
The trial court was undoubtedly led into giving the instruction complained of because of some language found in State v. Rivers, 58 Iowa, 102, and it must be confessed that there is warrant for such a charge in that opinion. .However, what was said in that case had reference primarily to the admissibility of certain testimony tending to show the motives of the prosecutor. As said in that opinion, such cases as this “ should be sifted to the bottom,” and nothing which tends to ■show that the prosecutor was using the criminal law to enforce the collection of a debt should be kept from the consideration1 •of the jury. But this is quite a different proposition from the broad statement that the motive of the prosecutor is alone sufficient to justify an acquittal, or that it has a direct- bearing
Other instructions are complained of, because they have no support in the evidence; arid because they applied the doctrine of reasonable doubt to specific detailed facts. These we shall not consider, for reasons already suggested, and for the further" reason that the detailed facts referred to were ultimate and essential facts necessary to be established to warrant a conviction. -
An instruction asked by the State and reading as follows should have been given:
This was the converse of- the one given by the court to which we have already made reference, and in fairness to the State it should have been given. There seems to have been evidence to support it.
There _was also error in permitting defendant to prove that by reason of the advance in the price of corn he did not make as much on the cattle purchased by him of Harrah as he had expected to, and that after receiving the cattle some of them died.
The judgment must in any event stand affirmed.
