Definition
"Black gap" does not appear as a recognized legal term of art in the Law Mind corpus or in standard Anglo-American legal usage. The entry retrieved under this heading in Black's Law Dictionary (2nd Ed.) Supplemental is not a definition of "black gap" but rather a definition of the black cap — the head-dress worn by a judge when pronouncing a sentence of death. The appearance of this entry under the search term is the result of an indexing or optical-character-recognition artifact, not a substantive match.
BLACK CAP (the actual term): The black cap is a square piece of black fabric worn by an English judge atop the judicial wig when formally pronouncing a death sentence. It is described by Wharton (cited in the Black's supplemental entry) as part of judicial full dress, worn on occasions of especial state. The practice is historical to English courts and has no operative counterpart in American legal procedure.

Common Confusion
Researchers encountering a source reference to "black gap" in an index, digest, or OCR-processed legal text should treat it as a probable misread or mis-sort of "black cap." The two terms are visually similar in certain typefaces and handwritten sources, and degraded historical print compounds the risk. No independent legal doctrine, evidentiary rule, or procedural concept called the "black gap" has been identified in the Law Mind corpus or in standard Anglo-American legal literature.

Why It Matters in Research
The central research lesson here is artifact identification. OCR errors, hand-digitization mistakes, and loose alphabetization in historical supplements can generate phantom entries — terms that appear in an index or search result but correspond to no genuine legal concept. "Black gap" is a textbook example.
If you encountered this term in a case, brief, or secondary source, the most productive next steps are:
1. Return to the original source document and verify the actual text. A scan of the physical page will resolve most OCR-generated confusion.
2. Search for "black cap" rather than "black gap" in historical English legal sources. The black cap has genuine doctrinal and ceremonial significance in English criminal procedure, particularly in capital cases from the 17th through 20th centuries.
3. If the term appears in an American source, verify whether the author was discussing English practice comparatively, as the black cap was never adopted in American courts.
Do not build a research chain on an unverified term. Phantom entries can propagate across secondary literature when researchers cite indexes rather than primary texts.

Historical Dictionary Support
The Black's Law Dictionary (2nd Ed.) Supplemental entry, as retrieved, reads: "The head-dress worn by the judge in pronouncing the sentence of death. It is part of the Judicial full dress, and is worn by the judges on occasions of especial state. Wharton." This is a definition of the black cap, with the Wharton citation pointing to Francis Wharton's legal lexicography. The entry is substantively consistent with what historical English legal dictionaries record about the black cap — a ceremonial item confined to English (and some Commonwealth) practice, carrying no procedural legal force in itself but serving as the formal signal that a death sentence was being pronounced.
No historical legal dictionary in the Law Mind shelf carries a substantive entry for "black gap" as an independent legal term.

Encyclopedia Cross-Reference
The matching encyclopedia entries returned for this search — Federal Workers' Compensation Programs (employment_115) and UCC Article 2 Gap-Fillers (contracts_109) — are not relevant to either "black gap" or "black cap" as legal concepts. Their appearance reflects the same index-matching artifact that generated this entry. Researchers should not treat those encyclopedia entries as substantively connected to this term.
If your research concern is gap-filling in contract law, proceed directly to: UCC Article 2 — Contract Formation Under Article 2 (Open Terms, Gap-Fillers), The Law Mind Contracts & Commercial Law Encyclopedia (contracts_109).
