Whether Illinois should apply the same standard to directed-verdict motions and judgments notwithstanding the verdict, and what that standard should be.
Holding
Yes. A directed verdict or judgment notwithstanding the verdict is proper only when all the evidence, viewed most favorably to the opponent of the motion, so overwhelmingly favors the movant that no contrary verdict could ever stand.
Reasoning
The Court held that the same inquiry governs both a directed verdict and judgment notwithstanding the verdict: whether the evidence presents a substantial factual dispute for the jury. In each setting, the question is whether the case may properly be removed from the jury's consideration.
Illinois precedent had used both an "any evidence" formulation and a reasonable-person formulation. The Court concluded that neither, taken literally, was fully satisfactory. A pure any-evidence rule could require submission to a jury even when the opposing proof was so weak and thoroughly rebutted that a verdict based on it could not survive review.
The Court distinguished a verdict that is merely against the manifest weight of the evidence from one that is legally unsustainable. A new trial may be appropriate when the verdict is against the manifest weight, but directing a verdict or entering judgment notwithstanding the verdict ends the litigation. That more final remedy requires a more conclusive evidentiary showing.
The jury-trial guarantee preserves the jury's role in resolving genuine factual disputes, including disputes turning on witness credibility. But it does not require submission where the evidence, considered as a whole and in the nonmovant's favor, overwhelmingly supports one result. Slight contrary evidence does not itself create a substantial jury question.
