Nathan Clifford, Weightman v. Corporation of Washington…
“ Where there is no evidence to sustain the action, or one of its essential elements, the court is bound so to instruct the jury; but where there is evidence tending to prove the entire issue, it is not competent for the court, although the evidence may be conflicting, to give an instruction which shall take from the jury the right of weighing the evidence and determining its force and effect, for the reason that, by all the authorities, they are the judges of the credibility of the witnesses, and the force and effect of the testimony. ”
