A directed verdict, now formally called judgment as a matter of law under Federal Rule of Civil Procedure 50(a), is a ruling that ends a jury trial before it reaches the jury because the evidence, viewed in the light most favorable to the non-moving party, provides no legally sufficient basis for a reasonable jury to rule in that party's favor. Either side can move for it once the opposing party has been fully heard on the issue, most commonly at the close of the plaintiff's case or at the close of all the evidence. If granted, the judge enters judgment directly, and the jury never deliberates on that claim or the case at all.

The standard is deliberately demanding: courts are reluctant to take fact-finding away from the jury, so a directed verdict is granted rarely and typically reserved for cases where a plaintiff has failed to introduce evidence on an essential element or a defense is legally unavailable regardless of disputed facts. It is distinct from summary judgment, which is decided before trial on the papers, and from a renewed motion for judgment as a matter of law (formerly JNOV) under Rule 50(b), which asks the judge to override an actual jury verdict after it has already been rendered.

In simulation terms, a directed verdict collapses every remaining branch of the trial trajectory into a single terminal outcome without ever reaching the jury decision node the rest of the model assumes. Juricratic represents this as a distinct, low-probability, case-ending branch rather than folding it into ordinary trial-outcome variance, because treating it as just another point on a continuous distribution would understate how sharply and completely it can end a case. Surfacing that branch separately also reminds a user that some risk in a trial track is procedural rather than evidentiary, and no amount of favorable jury modeling changes it.

Defense counsel move for judgment as a matter of law almost as a matter of course at the close of the plaintiff's evidence, both because it occasionally succeeds and because doing so preserves the issue for a post-verdict renewed motion and for appeal. Plaintiffs' counsel structure their case-in-chief specifically to make sure every element has at least some supporting evidence in the record, since a single missing element can end the case before the jury ever votes.
