I join with the majority in so far as it holds that the challenge to the juror should have been sustained, but I cannot bring myself to hold that the error could possibly have prejudiced the defendant. It is not claimed that any juror who sat upon the case was incompetent, or that a fair trial was not had because of the error in overruling the challenge to the juror. There is not, in my opinion, any ground upon which prejudice can be presumed. State v. Foster, 136 Iowa 527.
I would affirm.
