Hidden Weapon During Terry Stop
Lila Lin was detained on a street corner after an informant reported a concealed firearm. The officer reached directly into her waistband and recovered the gun. The discovery confirmed the presence of a latent threat that justified the limited intrusion.
Seizure of Concealed Personal Property
Lars Lindstrom stored valuable equipment in a warehouse that authorities suspected was subject to forfeiture. Agents seized the items without prior notice because the property could be quickly moved or hidden. The court later upheld the seizure of the latent assets subject to post-seizure safeguards.

Dictionaries
Lillian Locke left a will devising a lot she did not own. Extrinsic evidence showed the description closely matched a different parcel she actually held. The court used that evidence to resolve the latent ambiguity and pass the intended property.
Undiscoverable Manufacturing Flaw
Lola Langley bought a new car whose steering mechanism contained a hidden manufacturing defect. An expert later confirmed the flaw could not have been found by reasonable inspection. The defect's latent nature supported her claim despite the warranty disclaimer.
Luna Lang's attorney prepared interview notes that remained shielded from discovery. Opposing counsel sought the materials but could not show substantial need. The notes stayed protected because their content was latent and not otherwise available.

Peremptory Challenge Based on Hidden Bias

When is a manufacturing defect considered latent for purposes of a products claim?+
A manufacturing defect is latent when it cannot be discovered through reasonable inspection at the time of purchase or use. The Henningsen case illustrates that such hidden flaws support liability even when a warranty disclaimer exists.

Can extrinsic evidence cure a latent ambiguity in a deed or will?+
Yes. When the description in a donative document does not match any property the donor owns, extrinsic evidence may show the description fits another parcel the donor actually held and intended to convey. The court may then construe the document to pass the intended property.
