Definition
Questions of fact are issues in litigation that turn on what actually happened — the events, circumstances, conditions, and intentions that the trier of fact must determine from evidence. They are distinguished from questions of law, which ask what rule governs, and from mixed questions, which ask whether a set of facts satisfies a legal standard.
In the common law trial system, questions of fact are the province of the jury when a jury is present. The finder of fact weighs credibility, resolves conflicting evidence, and draws inferences. The judge, by contrast, resolves questions of law. This allocation — fact to jury, law to judge — is the organizing principle of common law trial procedure and carries constitutional significance in jurisdictions that guarantee jury trial rights.
The distinction is not always clean. Some factual determinations belong to the judge rather than the jury: preliminary or foundational facts necessary to rule on admissibility (Is this document authentic enough to be shown to the jury?), facts bearing on a witness's competence to testify, and facts relevant to the court's own jurisdiction. These are sometimes called "preliminary questions of fact" or "judicial fact-finding." They are resolved by the judge without submitting them to the jury, even though they are, in their nature, factual.
In appellate practice, questions of fact receive deferential review. Appellate courts generally will not disturb a factual finding unless it is clearly erroneous or against the manifest weight of the evidence. This deference reflects institutional design: the trial forum that heard and observed the evidence is better positioned to assess it.

Common Language
Modern common usage (Wiktionary): Plural of "question of fact" — no independent entry; treated as self-explanatory.
Historical common usage (Webster's 1913): Not separately defined; the component words carry their ordinary meanings.
The everyday phrase "a question of fact" suggests simply: something you could look up or verify. In law, the phrase carries structural weight. It determines who decides (judge or jury), what standard of review applies on appeal, and whether a constitutional jury-trial right attaches. The casual meaning misses all of that machinery.

Common Confusion
Questions of fact are frequently confused with mixed questions of law and fact, which ask whether established or assumed facts satisfy a legal standard — for example, whether a defendant's conduct was "reasonable" under the circumstances. Courts and commentators disagree about where to place mixed questions on the fact/law spectrum, and that placement has real consequences for the standard of appellate review. A researcher treating all reasonableness determinations as pure fact questions will misread the appellate case law.
Questions of fact are also confused with questions of legislative fact — background empirical propositions (social, economic, scientific) that inform the creation or interpretation of legal rules rather than the resolution of a particular dispute. Legislative facts are not found by juries and are not subject to the same evidentiary rules as adjudicative facts.

Core Elements
The fact/law allocation in any given case involves three recurring sub-questions:
1. WHO DECIDES: Jury (or judge sitting as factfinder) for disputed adjudicative facts; judge alone for preliminary admissibility facts, jurisdictional facts, and questions of law.
2. HOW IT IS DECIDED: Through evidence, witness testimony, and inference — not legal argument about what the rule is.
3. WHAT REVIEW APPLIES: Highly deferential on appeal (clear error, manifest weight, substantial evidence, depending on the context and jurisdiction). Questions of law receive de novo review; the deference gap between the two is practically significant.

Why It Matters in Research
The fact/law distinction is a load-bearing structure of procedural law, and it shifts depending on context. A researcher must track three variables simultaneously: the substantive area of law, the procedural posture (trial vs. appellate), and the historical period.
In historical sources, the allocation of preliminary fact questions to judges rather than juries was contested and unevenly settled. The Rapalje & Lawrence entry reflects a mid-to-late 19th century understanding in which the judge's role in resolving foundational facts (document authenticity, witness competence) was accepted but not uniformly codified. Modern evidence codes — particularly Federal Rule of Evidence 104 — have since formalized this allocation, but the underlying logic is the same. When reading pre-codification materials, do not assume the modern FRE framework applies.
In appellate research, the characterization of an issue as fact or law can be outcome-determinative. Courts sometimes strategically characterize issues to manipulate the standard of review. Be alert to this in judicial opinions, particularly in administrative law cases where the "substantial evidence" standard creates its own distinct regime.
The corpus connections matter: questions of fact in criminal cases intersect with mistake-of-fact doctrine (a defendant's mistaken belief about facts can negate mens rea — see the Mistake of Fact entry). In constitutional litigation, some seemingly factual questions are insulated from jury resolution by the political question doctrine. And the judicial notice rules carve out facts so well-established that no evidence is required at all — a formal exception to the ordinary fact/law machinery.
Researchers using historical legal dictionaries should note that pre-20th-century sources tend to discuss questions of fact primarily in the jury trial context, with limited treatment of the administrative law and appellate review dimensions that dominate modern doctrine. Do not read silence on those topics as suggesting they were nonexistent; they were simply handled elsewhere.

Historical Dictionary Support
Rapalje & Lawrence give a concise statement of the core rule as it stood in the common law tradition: the jury decides issues of fact, but questions of fact that are preliminary to a ruling of law — authenticity of a document for admission purposes, competence of a witness — fall to the judge. This formulation captures the essential structure that persists in modern doctrine.
What the entry does not address: the standard of appellate review of factual findings, the treatment of mixed questions, legislative versus adjudicative fact, or the administrative law context. These are 20th-century developments largely absent from 19th-century dictionary treatments. Rapalje & Lawrence's framing is useful precisely because it reflects the baseline common law allocation without the later codified elaborations — it is a reliable anchor for historical research but an incomplete guide to modern practice.

Jurisdictional Note
The fact/law distinction operates in all common law jurisdictions but with variation in the standards of appellate review and in how mixed questions are categorized. Civil law systems distribute adjudicative responsibility differently and do not map cleanly onto the common law jury/judge division. Federal and state systems in the United States also diverge on specific applications, particularly in administrative proceedings.
