Definition
A peremptory writ is a writ that commands its recipient to act without condition or alternative — it issues an absolute, unconditional directive rather than offering the recipient a preliminary opportunity to show cause or comply on their own terms. The term has two distinct but related applications in legal history:
1. As a form of original writ: In early common law procedure, the peremptory writ (also called the si te fecerit securum writ, named from its operative Latin words) was an original writ commanding the sheriff to compel the defendant to appear in court without any option or excuse, provided the plaintiff first gave the sheriff security to prosecute the claim in good faith. Unlike the pone or the bill of Middlesex, which allowed the defendant an initial opportunity to appear voluntarily, the peremptory writ bypassed that preliminary stage and compelled appearance directly. It was used narrowly — principally in cases where the plaintiff sought satisfaction in general rather than demanding a specific sum or thing.
2. As a final or absolute writ in extraordinary writ practice: In mandamus and other prerogative writ proceedings, a peremptory writ is the final, unconditional command issued by the court after the respondent has either failed to show cause against the writ or has shown cause that the court finds insufficient. It is distinguished from the alternative writ, which invites the respondent to comply or to appear and contest. The peremptory writ closes that dialogue and commands performance without further option.

Common Confusion
Peremptory writ is frequently confused with peremptory challenge, particularly when researchers encounter the word "peremptory" in jury selection materials. The two share only the adjective: a peremptory challenge in jury selection is an objection to a juror requiring no stated reason; a peremptory writ in procedural law is an unconditional court command. The connecting thread is the Latin root sense of "absolute" or "without option," but the legal mechanisms are entirely unrelated. Researchers working in criminal procedure should note that encyclopedia coverage of peremptory challenges (voir dire, Batson doctrine) will not address writ practice, and vice versa.

Core Elements
In extraordinary writ proceedings, the peremptory writ functions as the terminal stage of a two-step process:
Alternative writ stage: Court issues a preliminary writ commanding the respondent to perform the act or to appear and show cause why performance should not be ordered. The respondent has an opportunity to contest.
Peremptory writ stage: If the respondent fails to show sufficient cause, the court issues the peremptory writ — an absolute command to perform, carrying enforcement consequences for non-compliance. No further opportunity to contest the underlying obligation is available at this stage.
This two-step structure distinguishes peremptory writs from ex parte orders and from injunctions, and it is essential context when reading historical mandamus cases.

Why It Matters in Research
The term "peremptory writ" appears across centuries of common law materials in ways that require careful attention to context.
In early common law sources, the peremptory writ is a technical procedural artifact of original writ practice — a system that was abolished in England by the Common Law Procedure Acts of the mid-nineteenth century and was never transplanted wholesale into American practice. Researchers encountering the si te fecerit securum writ in pre-nineteenth century English reports should treat it as a historical curiosity rather than a live procedural tool.
In mandamus and extraordinary writ practice, the peremptory/alternative distinction remains alive and consequential. American courts — both federal and state — still use "peremptory writ of mandamus" as a technical term, and the distinction between the alternative and peremptory stages governs timing questions, the scope of review, and enforcement. Researchers analyzing mandamus proceedings must track where in this sequence a given writ or opinion falls.
Trap for historical sources: Older dictionaries and treatises sometimes use "peremptory writ" loosely to describe any final or urgent judicial command, without anchoring it to either the original writ system or the mandamus framework. Black's own entry conflates the original writ definition with the general proposition without fully separating the two contexts. Read historical uses with care.
Corpus connection: The term intersects with habeas corpus research because extraordinary writ doctrine developed in parallel across mandamus, certiorari, prohibition, and habeas. Understanding the peremptory/alternative structure in mandamus illuminates analogous structural questions in habeas proceedings.

Historical Dictionary Support
Black's Law Dictionary and Rapalje & Lawrence are in agreement on the core definition of the peremptory writ as an original writ — both anchor the definition in the Latin formula si te fecerit securum and describe its function as compelling defendant appearance without option, conditioned on plaintiff's security. The two sources are essentially parallel on this point, suggesting a shared derivation from English common law treatise tradition.
What both sources underemphasize is the peremptory writ's role in the mature extraordinary writ framework — the alternative-to-peremptory progression in mandamus practice that became the dominant context in which American lawyers and courts used the term from the nineteenth century forward. Historical dictionaries of this era were written primarily with English common law procedure as the reference point; American practitioners had already adapted the terminology into a somewhat different procedural context, and the dictionaries lag that development.
Neither Black's nor Rapalje & Lawrence addresses the abolition of the original writ system and the resulting narrowing of the term's practical meaning to extraordinary writ proceedings. Researchers relying on these sources alone risk applying a procedural framework that had already been superseded in the jurisdictions most relevant to their research.

Jurisdictional Note
In federal practice, the peremptory writ of mandamus is a recognized procedural form, though courts of appeals issue mandamus sparingly and the alternative/peremptory structure may be compressed or bypassed in urgent cases. State practice varies considerably: some states retain formal alternative and peremptory stages by rule or statute; others have modernized their writ procedures in ways that collapse or rename these stages. Researchers should verify current procedural rules for the specific jurisdiction before relying on the classical two-step framework.
