Robert Cooper Grier,
Richardson v. City of Boston (60 U.S. 263…
“ At the conclusion of the trial, the court, at the request of defendant's counsel, instructed the jury 'that there was not sufficient evidence in the cause to authorize the jury to find the rights claimed by the plaintiff.'As it is the duty of the jury to decide the facts, the sufficiency of evidence to prove those facts must necessarily be within their province. The jury cannot assume the truth of any material averment without some evidence; and it is error in the court to instruct the jury that they may find a material fact of which there is no evidence. ”
