Definition
A peremptory nonsuit is a nonsuit ordered by the court against a plaintiff, without the plaintiff's consent, as a matter of judicial compulsion rather than plaintiff's choice. It is distinguished from a voluntary nonsuit, in which the plaintiff elects to discontinue the action on their own initiative.
The term captures two ideas working together. "Nonsuit" refers to a termination of the plaintiff's case — historically, a judgment entered when the plaintiff failed to appear, failed to produce sufficient evidence, or otherwise could not proceed. "Peremptory" signals that the dismissal is mandatory and court-directed, not discretionary or optional. The court, upon finding that the plaintiff's evidence is legally insufficient to support a verdict, directs dismissal without giving the plaintiff further opportunity to cure the deficiency.
In practice, a peremptory nonsuit operates much like what modern procedure calls a directed verdict for the defendant at the close of the plaintiff's case, or a judgment as a matter of law under Rule 50 of the Federal Rules of Civil Procedure. The underlying logic is identical: the plaintiff has had a full opportunity to present evidence, and that evidence, viewed favorably to the plaintiff, cannot sustain a verdict.

Common Confusion
PEREMPTORY NONSUIT vs. VOLUNTARY NONSUIT: These are opposite procedures. A voluntary nonsuit is taken by the plaintiff as a matter of right (subject to conditions), typically to avoid an unfavorable ruling and preserve the ability to refile. A peremptory nonsuit is imposed by the court over the plaintiff's objection. Conflating the two matters for research purposes because their legal effects — including whether the plaintiff may refile — differ significantly across jurisdictions and historical periods.
PEREMPTORY NONSUIT vs. PEREMPTORY CHALLENGE: The word "peremptory" is shared with peremptory challenges in jury selection, where it means something structurally similar (a challenge requiring no stated reason) but arises in an entirely different procedural context. The encyclopedia entry linked above addresses jury selection and peremptory challenges; it is not directly relevant to this term.

Why It Matters in Research
The term belongs predominantly to older American and English procedural practice and is largely a creature of common law pleading. Researchers will encounter it frequently in nineteenth- and early twentieth-century case reporters, treatises, and practice manuals, but it has largely been displaced in modern jurisdictions by the language of directed verdicts and judgments as a matter of law under reformed civil procedure codes.
Several research traps apply:
First, terminological displacement. After the Federal Rules of Civil Procedure took effect in 1938 and state procedural reforms followed, courts stopped using "peremptory nonsuit" in most jurisdictions. A researcher looking for modern doctrine on insufficiency of plaintiff's evidence must search under directed verdict, judgment as a matter of law, or Rule 50 — not peremptory nonsuit. Historical sources will use the older term; modern sources will not.
Second, effect of the judgment. Whether a peremptory nonsuit operated as a judgment on the merits — barring relitigation — or merely as a dismissal without prejudice varied by jurisdiction and period. This distinction is critical when tracing preclusion questions in historical litigation files. Do not assume the modern rule applies to an older peremptory nonsuit without checking the governing law of the period.
Third, state survival. A handful of states retained the term and the procedure well into the twentieth century even after federal reform. Louisiana, for example, maintained distinct nonsuit rules for an extended period. Researchers in state-specific historical records should not assume uniform displacement.
Fourth, confusion in secondary literature. Older treatises sometimes use "nonsuit," "peremptory nonsuit," and "compulsory nonsuit" interchangeably, while others draw careful distinctions among them. Cross-check the specific author's usage before relying on a treatise's doctrinal characterization.

Historical Dictionary Support
Black's Law Dictionary defines a peremptory nonsuit as a compulsory or involuntary nonsuit — one ordered by the court, as distinguished from one the plaintiff takes voluntarily. This definition is accurate as far as it goes but is notably compressed. It captures the essential distinction (court-ordered versus plaintiff-elected) without addressing the procedural trigger, the standard for granting the nonsuit, or the legal effect of the judgment.
The definition's brevity reflects how well-settled the concept was among practitioners of the era for whom Black's was written. The procedural mechanics were assumed knowledge. For a modern researcher, the missing context is significant: the standard for a peremptory nonsuit was typically that the plaintiff had produced no legally competent evidence sufficient to go to the jury — a standard that courts applied with some variation depending on whether the court was sitting with or without a jury.
Historical dictionary sources do not meaningfully disagree on the core definition, because the concept was never particularly contested. What they omit, collectively, is the trajectory of the term's obsolescence and its relationship to modern directed-verdict practice. Researchers who find the term in historical sources should treat it as functionally equivalent to a modern judgment as a matter of law for the purpose of understanding the procedural posture of the case, while remaining alert to differences in preclusive effect under the law then in force.

Jurisdictional Note
The term was in general use across American common law jurisdictions through the nineteenth century and into the early twentieth. Federal courts and most state courts abandoned the terminology after procedural codification, substituting directed verdict and later judgment as a matter of law. Some states retained distinctive nonsuit procedures longer than others; researchers working in Southern and Gulf Coast state courts should verify local procedural history before assuming the term had the same meaning and effect as the general common law form.

Encyclopedia Cross-Reference
The Law Mind Criminal Law Encyclopedia entry on Jury Selection — Voir Dire, Peremptory Challenges, and Batson addresses peremptory challenges in the jury selection context and is not directly relevant to peremptory nonsuit. No single Law Mind Encyclopedia entry appears to address civil procedure or nonsuit doctrine directly. Researchers may find relevant background in encyclopedia entries covering trial procedure and burdens of proof.
