Georgian juries deliberately undervalued stolen goods to avoid the mandatory death penalty, a practice later called 'pious perjury'

Faced with a criminal law that made petty property theft a capital offense (see claim-englands-bloody-code-made-petty-property-theft-a-capital-crime), eighteenth-century English juries developed a systematic workaround: they lied under oath about value. "As the 18th century proceeded, jurors often deliberately under-assessed the value of stolen goods in order to avoid a mandatory death sentence" (Wikipedia, "Bloody Code", citing Glyn-Jones 2000, p. 322). A commonly repeated illustration — juries valuing goods at 39 shillings to keep them below the 40-shilling capital threshold for theft from a dwelling-house — remains [unverified-quant — needs primary]: it does not appear in the cited Wikipedia entry (checked 2026-07-12), and Blackstone's own example concerns the older twelvepence grand-larceny line, not the 40s one. The practice itself was widespread enough to function as an institutionalized nullification of the law's stated severity: the statute stayed on the books at full harshness while its enforcers quietly refused to run it at face value.

The maneuver acquired the name "pious perjury" — a perjury committed for mercy's sake. The coinage is confirmed against the primary: William Blackstone, Commentaries on the Laws of England, Book IV, ch. 17 ("Of Offences Against Private Property"; Avalon Project full text, checked 2026-07-12, re-checked independently 2026-07-25) — "the mercy of juries will often make them strain a point, and bring in larciny to be under the value of twelvepence, when it is really of much greater value: but this is a kind of pious perjury," which, he adds, does not excuse the common law "from the imputation of severity." Two details worth keeping straight: Blackstone's own example is the twelvepence grand-larceny threshold, not the 40-shilling one, and he offers the practice as evidence against the law's severity, not as a defense of it. The general mechanism and the 40-shilling dwelling-house threshold itself are now sourced to a Tier 2 account — Robert Shoemaker, the Old Bailey Proceedings Online project's own lead historian, writing on the project's methodology page (2022-03-04): "Until 1827, defendants found guilty of stealing goods worth 40 shillings or more from a dwelling house were subject to a mandatory sentence of death," and juries "engaged in such 'pious perjury' with broad judicial and public support in order to save lives" — replacing this note's earlier reliance on Wikipedia for that half. The 39-shilling arithmetic tied to a specific case remains [unverified-quant — needs primary]: see claim-duglass-1750-old-bailey-case-cited-as-39-shilling-undervaluation for a named 1750 candidate case that is itself still unread against the primary. That remaining gap stays routed in question-verify-blackstone-pious-perjury-coinage-and-jury-undervaluation. (An earlier version of this note attributed both the coinage and the shilling example to the Wikipedia "Bloody Code" entry; that entry carries neither — corrected 2026-07-12.)

This is the human hinge of the whole hop chain: a supply chain leaking stolen brass (claim-georgian-instrument-workshops-drew-brass-partly-from-a-stolen-metal-trade) fed a capital-punishment regime that jurors then declined to enforce. It sits beside a neighboring puzzle about jurors and their conscience — claim-whitman-reasonable-doubt-began-as-juror-soul-protection argues the "beyond reasonable doubt" standard arose to protect jurors from the moral peril of wrongful conviction. Pious perjury is the same instinct expressed as action rather than doctrine: jurors managing the moral weight of a death sentence by bending the facts.
