text: Juries usually weigh the evidence and testimony to determine questions of fact, while judges usually rule on questions of law, although the dissenting justices of the Supreme Court case Sparf et al. v. U.S. 156 U.S. 51 (1895), generally considered the pivotal case concerning the rights and powers of the jury, declared: “It is our deep and settled conviction, confirmed by a re-examination of the authorities … that the jury, upon the general issue of guilty or not guilty in a criminal case, have the right, as well as the power, to decide, according to their own judgment and consciences, all questions, whether of law or of fact, involved in that issue.”
