Definition
A peremptory rule is a court order that must be obeyed immediately and without qualification. It admits of no condition, no alternative, and no opportunity for the party subject to it to show cause why it should not be enforced. The order is final in the sense that it does not invite argument or compliance on terms — it simply commands.
In older English and American practice, the peremptory rule appeared most prominently as a procedural device to force a dilatory party to act. When a plaintiff failed to file a declaration within the time allowed, the defendant could obtain a peremptory rule to declare, compelling the plaintiff to proceed or face dismissal. This was distinguished from a rule to show cause, which gave the party an opportunity to explain or contest before the court acted.
The term "rule" here carries its procedural sense: a court-issued directive, not a general legal principle.

Common Language
Modern common usage (Wiktionary): "Peremptory" means admitting no refusal or denial; absolute and final; sometimes carrying a tone of imperious command.
Historical common usage (Webster's 1913): "Precluding debate or expostulation; not admitting of question or appeal; positive; absolute; decisive."
The common meaning of "peremptory" as simply "bossy" or "imperious" understates the technical legal function of the word. In legal usage, peremptory does not merely describe tone — it describes a procedural category. A peremptory rule is structurally different from a conditional order: it forecloses the responding party's ability to contest, explain, or delay. The gap between "commanding in manner" and "foreclosing procedural response" is the one that trips researchers working with historical court records.

Common Confusion
Peremptory rule is most easily confused with two related but distinct concepts:
First, the peremptory challenge in jury selection — the right of counsel to excuse a prospective juror without stating a reason. The word "peremptory" functions similarly in both contexts (unconditional, requiring no justification), but a peremptory challenge is a litigation right, not a court order. The two are unrelated procedurally.
Second, the rule to show cause — the near-opposite of a peremptory rule. A rule to show cause gives the responding party an opportunity to appear and argue before any consequence attaches. Historical pleading records often reference both, and the distinction between them is the difference between conditional and unconditional court action. Researchers skimming older records may miss which type of rule was issued.

Why It Matters in Research
The peremptory rule belongs primarily to the era of common law pleading, when courts managed dilatory parties through a structured system of rules and defaults. Its appearance in historical court records — especially English and early American — is a marker of procedural posture, not substantive ruling. Seeing a peremptory rule in the record tells you that one party was forcing another to act, and that the court had already moved past any conditional stage.
Researchers working in equity practice will encounter the term differently. Equity courts used their own rule-based management systems, and what common law courts called a peremptory rule had functional equivalents in equity under different names. Cross-checking between law and equity records requires awareness of this terminological divergence.
The term has largely fallen out of modern procedural vocabulary in American courts. Federal and state civil procedure rules absorbed and replaced the old system of rules to declare, rules to plead, and similar devices. When the term appears in modern legal writing, it is almost always in the context of peremptory challenges, not peremptory rules in the classical procedural sense. This shift creates a research trap: searching "peremptory rule" in modern databases will surface jury selection materials, not the historical procedural device.
Bouvier's definition preserves the most historically useful detail — the specific mechanism of the rule to declare — which Black's and Burrill's omit. For researchers tracing the procedural history of a common law action, Bouvier's account is the better starting point.

Historical Dictionary Support
Black's and Burrill's agree closely, offering nearly identical definitions: an absolute rule, without condition or alternative of showing cause. Both treat the peremptory rule as the straightforward opposite of a conditional rule. Neither elaborates on the specific procedural contexts in which the device appeared.
Bouvier's is more useful to the practicing researcher. It identifies the rule to declare as the paradigm case, explains the mechanism (defendant compelling plaintiff to proceed when plaintiff has delayed), and attributes the definition to Anderson's law dictionary — a signal that this usage was well-settled in practice, not merely theoretical. Bouvier's framing also captures something the other two miss: the rule's function was not merely to command, but to cut off further delay or argument by the opposing party.
What all three historical sources omit is any discussion of how the peremptory rule functioned in equity, or how it related to the broader system of conditional and absolute rules used to manage case progression. Researchers looking for that context will need to consult treatises on common law pleading rather than the dictionary entries alone.

Jurisdictional Note
The peremptory rule as a distinct procedural device was more fully developed in English practice and in American jurisdictions that closely followed English common law pleading. With the adoption of the Field Code in New York (1848) and eventually the Federal Rules of Civil Procedure (1938), the formal system of pleading rules that gave rise to the peremptory rule was substantially displaced. The term survives in historical records across most common law jurisdictions but is not a functional term of art in modern American civil procedure.

Encyclopedia Cross-Reference
Jury Selection — Voir Dire, Peremptory Challenges, and Batson (The Law Mind Criminal Law Encyclopedia): Covers the peremptory challenge — a distinct but etymologically related concept. Useful for understanding the broader legal meaning of "peremptory" as a term of art, and essential context if research touches jury selection rather than historical pleading procedure.
