Definition
A case certified is a procedural mechanism by which a lower court — historically a federal circuit court — formally transmits a specific, discrete question of law to a higher court for resolution. Rather than appealing the entire case, the court below identifies a precise legal proposition on which the judges are divided or uncertain and submits that question alone to the superior tribunal. The higher court answers the certified question; the answer is then returned to the originating court for application to the pending matter.
In the federal system, the device has historically allowed circuit courts to obtain authoritative guidance from the Supreme Court on unsettled legal questions arising mid-proceeding, without waiting for final judgment and full appellate review.

Common Confusion
"Case certified" should not be confused with certification of a class action under Rule 23, which determines whether a lawsuit may proceed on behalf of a defined group of plaintiffs. Nor should it be confused with the certification of records for authentication purposes — the process by which official custodians attest to the accuracy of copies. All three procedures use the word "certified" or "certification," but they operate on entirely different legal logics. Class certification concerns party structure; record certification concerns evidentiary foundation; case certification concerns the transmission of a legal question between courts.

Core Elements
For a case certified to be properly presented — and for the receiving court to accept jurisdiction — the certified question must satisfy several formal requirements:
1. Distinct point or proposition of law. The question must be cleanly severable. It cannot sweep in the broader factual or legal controversy; it must stand on its own.
2. Clear statement. The question must be formulated with enough precision that the higher court can answer it without needing to resolve the underlying facts or other contested issues in the case.
3. Not equivalent to the whole case. Certification is not a mechanism to transfer the entire dispute upward. If answering the question would effectively decide the case, courts have historically declined to treat it as a proper certified question.
4. Genuine division or uncertainty. The procedure is triggered by a real legal impasse — historically, a division of opinion among circuit judges — not by a party's preference for a different tribunal.

Why It Matters in Research
Researchers working in pre-twentieth-century federal practice will encounter case certified as a distinct procedural category, particularly in Supreme Court records and reporters from the nineteenth century. Questions certified from the circuit courts to the Supreme Court appear in the reports under their own heading and may not be indexed as conventional appeals. A researcher tracing the development of a legal doctrine may find early Supreme Court pronouncements that originated not from adversarial appeals but from certified questions — meaning the factual record is thin and the Court's language is more abstract than usual.
The restrictive formal requirements — especially the rule that the question must not involve the whole case — generated significant litigation over what qualified. Courts were skeptical of attempts to use certification as a workaround for interlocutory appeals. This tension is visible in the case law Bouvier cites and shapes how nineteenth-century practitioners drafted certified questions.
In modern federal practice, certification has migrated in important ways. The Supreme Court's direct receipt of certified questions from lower federal courts is now narrow and infrequent. But certification has proliferated in a different direction: most states now permit or require federal courts sitting in diversity to certify unsettled questions of state law to that state's highest court. These modern state-law certification procedures share the same structural logic — discrete question, clean formulation, no wholesale transfer of the case — but operate under rules that vary considerably by jurisdiction.
Researchers should not assume that a historical source's treatment of case certified maps neatly onto modern certification practice. The procedural context, the receiving court, and the governing rules have all shifted.

Historical Dictionary Support
Bouvier's treatment is concise but precise. The definition centers on the federal circuit-to-Supreme Court mechanism and articulates the core formal requirements in terms that closely track the case law of the period: the question must be a "distinct point or proposition of law so clearly stated that it can be answered without regard to the other issues of law or fact in the case," and "it must not involve the whole case." Bouvier's entry is incomplete as extracted — the final sentence trails off — but the substance it conveys accurately reflects how nineteenth-century courts policed the boundaries of the procedure.
The historical dictionaries are more useful here for confirming the procedural architecture than for illuminating contested meaning. The requirements Bouvier describes were the product of judicial interpretation rather than explicit statutory command, and they reflect a recurring concern: that certification not become a mechanism for evading the final judgment rule by routing half-developed cases upward prematurely.
What historical sources do not address is the modern state-law certification variant. That development is entirely absent from Bouvier-era sources and must be supplied from contemporary procedural materials.

Jurisdictional Note
In the modern federal courts, certification of questions to the Supreme Court is governed by 28 U.S.C. § 1254(2) and is rarely used. The more active variant today is federal-to-state certification, by which a federal court asks a state supreme court to resolve an unsettled question of that state's own law. Availability, procedure, and the degree to which state courts are obligated to accept certified questions vary significantly by state.
