Armory v Delamirie
(1722) 1 Strange 505 · 93 ER 664 · [1722] EWHC KB J94
Court of King’s Bench · 31 July 1722 · Pratt CJ
The plaintiff, described in the report as a chimney sweeper’s boy, found a jewel and took it to a goldsmith’s
shop to have it valued.
The jewel was handed to the goldsmith’s apprentice. Under the pretence of weighing it, the apprentice removed
the stones from the setting. The apprentice then told his master that the item was worth three halfpence.
The master offered that amount to the boy, who refused it and asked for the jewel to be returned.
The boy received only the empty setting. The stones were not returned.
He brought an action in trover against the master.
The King’s Bench ruled that the finder did not acquire absolute ownership merely by finding the jewel.
But the finder did acquire a possessory title sufficient to maintain an action against anyone other than
the rightful owner.
The finder had a possessory property right good against everyone except the rightful owner.
The court also held that the action could be maintained against the master in relation to the conduct
of his apprentice.
The most distinctive evidentiary feature of the case concerned the missing stones.
The report records that several members of the trade gave evidence about the value of a jewel of the finest
quality that would fit the socket.
Pratt CJ directed the jury that, unless the defendant produced the jewel and showed that it was not of the
finest quality, the strongest inference should be made against the defendant and the value of the best
fitting jewel should be used as the measure of damages.
The evidentiary point:
where the object needed to determine its value was not produced by the defendant,
the uncertainty created by that non-production was resolved against the defendant in the assessment of damages.
The case illustrates an old common-law evidentiary principle: when a party responsible for the relevant
object does not produce it, the court may have to deal with the resulting uncertainty.
In Armory, the response was not to invent a precise value unsupported by evidence.
Instead, the jury was directed to adopt the strongest valuation against the defendant because the defendant
had failed to produce the jewel and demonstrate that it was of lesser quality.
The principle is therefore more precise than the modern shorthand “spoliation penalty.”
It concerns the evidentiary consequences of non-production in the particular damages assessment before the court.
When a disputed object or piece of evidence is unavailable,
what caused its absence, who had control over it, and what evidentiary consequence follows?
That question is considerably broader than the facts of Armory v Delamirie, and the case should not
be presented as establishing a universal modern rule for every missing document, recording or item of evidence.
Its value lies in showing how the common law confronted evidentiary uncertainty when the relevant object
was not produced.

Armory draws a precise distinction between absolute ownership and a legally protected possessory interest.
The finder did not acquire an unqualified title against the whole world. He acquired a property interest sufficient to maintain an action against everyone except the rightful owner.
Possession can create a legally enforceable interest even where absolute historical title has not been established.
The relevant question is therefore not simply who can prove perfect title, but whose legal interest prevails against the particular person asserting a competing claim.
The second principle concerns the jewel itself. The apprentice removed the stones before returning the setting, leaving the court without the original object whose value was in dispute.
The court did not treat that absence as a neutral evidentiary gap.
Contemporary reports state that, because the defendant did not produce the jewel, the jury was directed to presume the strongest case against him when assessing its value.
The measure was the value of the finest jewel that could reasonably fit the socket.
This is more precise than describing Armory as creating a universal modern “spoliation penalty.”
The case establishes a judicial response to a missing object in a specific property dispute: where the defendant controlled the relevant evidence and failed to produce it, the evidentiary uncertainty was not simply resolved in his favour.
Armory does not establish that every missing document, recording, photograph, or physical object must automatically generate an adverse inference.
It does, however, provide an enduring evidentiary question:
who had control of the evidence, why is it unavailable, and what legal consequence should follow from its absence?
Armory v Delamirie was a property dispute decided in the early eighteenth century.
It does not establish a general rule that modern courts, prosecutors, or public authorities are legally presumed to have acted improperly whenever evidence is unavailable.
Its continuing relevance lies in the narrower evidentiary principle:
a party responsible for withholding the best available evidence cannot necessarily demand that the resulting uncertainty operate entirely in its own favour.
When the evidence needed to test a claim is no longer available, who controlled that evidence — and who should bear the resulting uncertainty?
