Definition
Defossion is a historical form of capital punishment in which the condemned person was buried alive. It was imposed under certain ancient and medieval legal systems and is now entirely abolished. The term appears in legal dictionaries as a matter of historical record rather than as a doctrine with any continuing legal application.

Common Confusion
Defossion should not be confused with other archaic capital punishments catalogued in historical legal sources, such as immurement (walling a person into a structure) or inhumation in a purely religious or funerary sense. The defining legal characteristic of defossion is that burial itself was the instrument of execution, not a post-mortem act. Researchers encountering references to ancient punishments in historical sources should take care not to conflate defossion with related but distinct forms of death by suffocation or entombment described under different names in ecclesiastical or civil law texts.

Why It Matters in Research
Defossion is a term a researcher will encounter almost exclusively in two contexts: historical surveys of punishment and annotated legal dictionaries that carry forward entries from earlier editions without updating them for modern relevance.
The practical research risk is one of context collapse. A researcher working in early English, Roman, or ecclesiastical legal history may find defossion referenced in proximity to terms that remained legally operative far longer, such as attainder, corruption of blood, or the various forms of aggravated execution associated with treason. Defossion in those sources is often a catalog entry rather than a term of art with procedural content — it describes what was done, not a structured legal doctrine with elements, defenses, or remedies.
Researchers should also note that none of the historical dictionaries in the Law Mind corpus provide meaningful jurisdictional attribution for defossion — that is, none of them identify with precision which legal systems actually imposed it, under what authority, or during what period. Bouvier simply cites Black, and Black offers no further sourcing. This daisy-chaining is a common problem with archaic punishment terms in nineteenth-century legal dictionaries: compilers reproduced entries from earlier authorities without independent verification or historical elaboration. A researcher seeking to establish the actual historical practice should look beyond legal dictionaries to primary sources in Roman law, canon law, and comparative criminal history rather than relying on the dictionary lineage.
Defossion is occasionally relevant in comparative constitutional scholarship addressing the Eighth Amendment's prohibition on cruel and unusual punishment, where surveys of historically condemned execution methods are assembled to establish the outer boundary of permissible state action. In that context, defossion appears as evidence of what Anglo-American legal tradition had long considered barbaric, even when the precise historical record behind the dictionary entry is thin.

Historical Dictionary Support
All four sources in the Law Mind corpus agree on a single, brief definition: defossion is the punishment of being buried alive. There is no meaningful divergence among them. Black's Law Dictionary (1st edition) contains a minor textual artifact — a fragment referencing "titles of inferior officers, (especially ecclesias-" — that appears to be a printing or compilation error in which text from an adjacent column was captured alongside the defossion entry. This artifact does not appear in the 2nd edition of Black's or in Bouvier or Rapalje & Lawrence, and it carries no substantive legal meaning.
Rapalje & Lawrence places defossion immediately adjacent to entries for Defraud and Defraudation, reflecting the purely alphabetical organization of that dictionary rather than any conceptual relationship between the terms.
What the historical dictionaries do not provide: any citation to authority, any identification of the legal systems in which defossion was practiced, any discussion of whether it was ever imposed under English common law, or any note of its abolition. The entries are definitional placeholders, not substantive legal analysis.
