Definition
Failure of evidence is a trial concept describing the situation in which a party — most commonly the plaintiff — has not produced sufficient proof to establish one or more facts that are legally necessary to win on an issue. It operates as a threshold judgment: if a required element of a claim has no evidentiary support, the entire case fails regardless of the strength of proof on other elements.
The concept has two recognized gradations:
1. Total failure of evidence. The complete absence of any proof — positive or inferential — on a fact that must be established. No witness, no document, no reasonable inference from the record supports the required finding. Courts have treated this as grounds for directed verdict or nonsuit.
2. Partial or technical failure of evidence. Proof is present but falls short of establishing one or more of the facts indispensable to the claim. The party has attempted proof but the attempt is legally insufficient to carry the issue. This is the more commonly litigated form.
Both forms share a core consequence: the trier of fact cannot properly find for the party bearing the burden of proof, and the opposing party is entitled to relief as a matter of law.
Common Confusion
Failure of evidence is frequently conflated with insufficiency of evidence and with variance. These are related but distinct concepts. Insufficiency of evidence typically means that evidence was presented but does not meet the applicable standard of proof — it is a quantitative or qualitative judgment on evidence that exists. Failure of evidence means the required proof was not offered at all, or was so entirely absent on a controlling fact that the issue was never properly before the fact-finder. Variance, by contrast, arises when evidence offered does not match the pleadings — proof was present, but it proved something different from what was alleged. A researcher conflating these terms in older materials will misread procedural rulings and the grounds on which judgments were entered.
Why It Matters in Research
This term appears most often in older American and English common law materials governing motions for nonsuit, directed verdict, and judgment notwithstanding the verdict. Researchers working in nineteenth- and early twentieth-century trial records, appellate opinions, or procedural treatises will encounter "failure of evidence" as a term of art with specific procedural consequences that do not map cleanly onto modern Rule 50 (federal) or equivalent state motions practice.
Several traps exist for corpus researchers:
First, the term was used both procedurally and substantively. A court might use "failure of evidence" to describe the grounds for granting a nonsuit (procedural consequence) while also using it to describe the evidentiary state of the record (substantive description). Context must be read carefully.
Second, the phrase "total failure of evidence" in historical sources does not always mean what a modern reader might expect — namely, a completely empty record. Courts, including in the Maryland authority cited by both Black's and Bouvier's, used "total" to mean failure on any single indispensable fact, not only failure to introduce any evidence at all. This expansive use of "total" is counterintuitive and has caused misreading in secondary literature.
Third, the term connects directly to the allocation of the burden of proof. Failure of evidence is always evaluated against the party who bears the burden on the contested fact. Researchers examining equity cases should note that burdens sometimes shifted mid-proceeding, making the question of whose evidence "failed" more complex than it appears in law cases.
Fourth, modern civil procedure has largely absorbed this concept into directed verdict and summary judgment doctrine without preserving the exact terminology. When researching modern materials, look for the functional equivalents rather than the phrase itself.
Historical Dictionary Support
Black's and Bouvier's are in near-complete agreement here, and both trace to the same underlying authority — a Maryland appellate source reported at 7 Gill & Johnson 28. This convergence is notable: both dictionaries are quoting or closely paraphrasing the same judicial language rather than offering independent synthesis.
What the historical dictionaries do not address is the procedural vehicle by which failure of evidence was raised. Neither Black's nor Bouvier's explains the distinction between a motion for nonsuit and a directed verdict, or how courts treated partial versus total failure differently in practice. Researchers relying on dictionary definitions alone will miss the procedural mechanics that determined what remedy followed a finding of failure of evidence.
Both dictionaries frame the concept exclusively from the plaintiff's perspective — "finding of the issue for the plaintiff" — reflecting the common law structure in which plaintiffs bore the primary burden and defendants invoked failure of evidence as a defense to the claim. This plaintiff-centric framing is accurate for its era but should not be read as excluding the concept's application to defendants bearing affirmative burdens.
Jurisdictional Note
The foundational judicial language in both historical dictionary entries originates from Maryland. Application and terminology varied across American jurisdictions, particularly as code pleading states departed from common law nonsuit practice in the late nineteenth century. Federal practice after the adoption of the Federal Rules of Civil Procedure in 1938 consolidated this doctrine under Rule 50 directed verdict standards, effectively retiring "failure of evidence" as a term of art in federal courts.
