¶1The trial in this cause resulted in defendant being convicted of manslaughter in the fourth degree and his punishment assessed at a fine of $500.
¶2Among other instructions given by the court of its own motion was the following: “Thé jury is further instructed that the defendant and his wife are competent witnesses in behalf of the defendant, and the jury should not discard their testimony for the reason alone that one is the defendant in this case and' on trial, and the other is his wife: but such facts may be considered by the jury in determining the credit to be given to their respective testimony; and the jury is further instructed that they are the sole judges of the credibility of the witnesses and of the weight of the evidence, and if the jury believe from the evidence that any witness has intentionally sworn falsely as to any material fact in the case, then they are at liberty to disregard the whole or any part of the testimony of such witness.”
¶3This instruction, so far as the defendant is concerned, is the counterpart of one given by the same learned judge in Austin’s case, 113 Mo. 538, which was one cause of reversal in that case. The instruction *622here is doubly erroneous, for the reason that a similar rule is laid down in it as to the wife of defendant.
¶4Judgment reversed and cause remanded.
