Definition
A mandate is a command, direction, or authorization issued by a recognized authority. The term carries distinct meanings depending on context, and researchers should treat each as a functionally separate concept.
1. Appellate Mandate. In appellate practice, a mandate is the formal instrument by which an appellate court communicates its judgment to the lower court and directs the action to be taken on remand. It is the operative mechanism that gives effect to an appellate decision — without issuance of the mandate, the lower court generally lacks authority to proceed. The mandate typically issues after the expiration of time for rehearing or, in federal practice, after any stay is lifted.
2. Judicial Command or Writ. More broadly, a mandate is any judicial command or precept issuing from a court or judicial officer directing a named person, officer, or body to do or refrain from doing a specified act. In this sense it overlaps with mandamus, though the two are not identical.
3. Bailment by Mandate (Civil Law). In the civil law tradition, mandate denotes a specific type of bailment: a gratuitous commission by which one party (the mandant) entrusts another (the mandatory or mandatary) to perform some act or manage some business on the mandant's behalf, without compensation. The absence of reward distinguishes mandate from hire. This usage is prominent in Louisiana law and jurisdictions drawing on civil law sources.
4. Direction or Request (Commercial). In a looser but legally recognized sense, a mandate is any direction from one party to another to perform a specific act. A check, for example, has been characterized as a mandate from the drawer to the bank. A power of attorney to receive payment may also constitute a mandate.
5. Legislative or Electoral Mandate. In constitutional and political law, a mandate refers to the authority conferred by voters or a legislative body on an elected official or government to pursue a particular course of action. Coverage mandates in regulatory law — such as requirements that insurers cover specified health services — derive from this usage.

Common Language
Modern common usage (Wiktionary): The standard legal and general meaning — an authoritative command or commission — is well established in common usage. (Note: Wiktionary's alternative definition as "a date between two men" is informal wordplay and has no bearing on legal meaning.)
Historical common usage (Webster's 1913): "An official or authoritative command; an order or injunction; a commission; a judicial precept." Webster's also captures the civil law contractual sense: "A contract by which one employs another to manage any business for him."
The gap between common and legal meaning is real but subtle. In everyday use, "mandate" most often means simply a strong directive or an electoral authorization. In law, the term splinters into at least three technically distinct concepts — the appellate mandate (a procedural instrument), the civil law bailment (a gratuitous agency contract), and the coverage or regulatory mandate (a statutory obligation). A researcher who imports the common meaning uncritically into any of these contexts will misread the source.

Common Confusion
MANDATE vs. MANDAMUS. These terms share a root and both involve judicial commands, but they are not interchangeable. Mandamus is a writ — an extraordinary remedy compelling a public official or lower tribunal to perform a ministerial duty. An appellate mandate is the routine instrument by which any appellate judgment is transmitted to the lower court. Historical sources, including Rapalje & Lawrence, treat mandamus extensively in a section adjacent to mandate entries, and the proximity can blur the distinction. Burrill and Bouvier handle them as separate entries; researchers should not assume that pre-20th century sources using "mandate" in a quasi-public-law context are referring to mandamus.
MANDATE (appellate) vs. REMAND ORDER. The mandate is the vehicle; the remand is the instruction it carries. Some sources use these terms loosely as synonyms, particularly older digests.
MANDATORY (civil law agent) vs. MANDATORY (obligatory). The noun "mandatory" or "mandatary" refers to the agent in a civil law mandate relationship. The adjective "mandatory" means required or obligatory. In a single paragraph discussing insurance coverage mandates, both senses may appear. Context is essential.

Recognized Forms
/SUBTYPES
Appellate Mandate: Issues from a reviewing court to the court below following decision on appeal or writ of error.
Interlocutory Mandate: Recognized under English procedural reform and some American reformed codes; may issue before final judgment where the court finds it just or convenient. Rapalje & Lawrence notes this expressly in connection with the Common Law Procedure Act, 1854.
Civil Law Mandate (Mandat): The gratuitous agency contract of Roman and civil law origin. Survives in Louisiana, Quebec, and other mixed civil law jurisdictions.
Coverage Mandate: A statutory or regulatory requirement imposed on insurers, employers, or individuals to provide or obtain specified coverage. The term entered broad public discourse in connection with the Affordable Care Act.
Imperial Mandate (Historical): In Roman and later civil law, instructions addressed by the emperor to public functionaries governing their conduct. Black's first edition notes these resembled the mandata jurisdictio of proconsuls.

Why It Matters in Research
Researchers face two primary hazards with this term: false equivalence across its distinct legal meanings, and the appellate procedural significance of mandate timing.
On meaning: A 19th-century treatise discussing "mandate" in the context of agency or bailment is almost certainly discussing the civil law gratuitous commission — not an appellate court order. Modern federal cases discussing "the mandate" in appellate procedure are discussing something entirely different. The same word in a constitutional law article about electoral authority is different again. Do not assume continuity of meaning across doctrinal fields or time periods.
On appellate procedure: The issuance of the mandate is a procedurally critical event in appellate practice. It determines when the lower court regains jurisdiction, when judgments become final for enforcement purposes, and when the time for further review begins to run. Historical sources are thin on the mechanics of mandate issuance; researchers relying on pre-20th-century materials for current appellate practice will find significant gaps. Federal Rules of Appellate Procedure, Rule 41, governs mandate issuance in the federal courts and is the controlling modern source — none of the historical dictionaries in the Law Mind corpus address this rule directly.
On coverage mandates: The regulatory mandate — requiring individuals, employers, or insurers to provide or obtain coverage — is the dominant popular usage following the ACA litigation. Historical dictionaries are silent on this meaning. Researchers approaching health law sources should not expect the historical corpus to illuminate contemporary statutory mandate doctrine.
The civil law mandate/bailment sense is critically important for Louisiana law research and for understanding older commercial and agency materials drafted in the civil law tradition. Bouvier, writing with civil law awareness, handles this usage more fully than Black's.

Historical Dictionary Support
The historical dictionaries converge on the core judicial and civil law meanings but diverge in emphasis and completeness.
Black's Law Dictionary (both editions) leads with the appellate practice meaning — "a judicial command or precept proceeding from a court or judicial officer, directing the proper officer to enforce a judgment, sentence, or decree" — and briefly acknowledges the civil law contractual sense and the looser commercial usage (the check as mandate). Black's first edition also includes the Roman imperial mandate. Neither edition anticipates the regulatory coverage mandate.
Rapalje & Lawrence distinguishes between the judicial mandate and the civil law bailment mandate more clearly than Black's, and is the only source in this corpus to address the interlocutory mandate specifically, in connection with English procedural reform. This makes Rapalje particularly useful for researchers working with 19th-century English or early American reformed procedure materials.
Bouvier handles the term with characteristic breadth, covering the commercial direction, the power of attorney usage, and the judicial precept. Bouvier's civil law sensitivity gives his treatment of the bailment form more texture than Black's.
Anderson's Dictionary of Law offers a notably broad statutory-style definition that anticipates modern administrative usage: mandate includes "a writ, process or other written direction issued pursuant to law out of a court, or made pursuant to law, by a court, or a judge, or a person acting as a judicial officer." This is practically useful for researchers working with statutory definitions in late 19th and early 20th-century codes.
What the historical sources collectively miss: the procedural mechanics of appellate mandate issuance and recall; the constitutional and administrative dimensions of coverage mandates; and the full doctrinal framework around the ACA individual mandate. Researchers should treat historical dictionary entries as foundational context only, not as current doctrine.

Jurisdictional Note
The civil law mandate (gratuitous commission/bailment) retains significant independent doctrinal life in Louisiana, where the Civil Code treats mandate as a named contract. Researchers working in Louisiana law should consult the Louisiana Civil Code articles on mandate, not common law agency doctrine. In other U.S. jurisdictions, the civil law sense has largely been absorbed into general agency law and the term rarely appears in this technical sense in modern case law outside Louisiana.
