Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 215 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“When a motion for a directed verdict has been properly made, and the trial court, after construing the evidence most strongly in favor of the party against whom the motion is directed, finds that upon any determinative issue reasonable minds could come to but one conclusion upon the evidence submitted and that conclusion is adverse to such party, the court shall sustain the motion and direct a verdict for the moving party as to that issue.”
32 later decisions quote this exact passage“When a motion for a directed verdict is entered, what is being tested is a question of law; that is, the legal sufficiency of the evidence to take the case to the jury. This does not involve weighing the evidence or trying the credibility of witnesses; it is in the nature of a demurrer to the evidence and assumes the truth of the evidence supporting the facts essential to the claim of the party against whom the motion is directed, and gives to that party the benefit of all reasonable inferences from that evidence.”
11 later decisions quote this exact passage“A motion for directed verdict * * * does not present factual issues, but a question of law, even though in deciding such a motion, it is necessary to review and consider the evidence.”
