Peter Vivian Daniel, Roach v. Hulings — Opinion of the Court
“ In trials at law, whilst it is invariably true, that the decision of questions upon the weight of the evidence belongs exclusively to the jury, it is equally true, that wherever instructions upon evidence are asked from the court to the jury, it is the right and duty of the former to judge of the relevancy, and, by necessary implication, to some extent, upon the certainty or definiteness, of the evidence proposed. ”
