United States v. Duffy
Citation and Court
454 F.2d 809 (5th Cir. 1972), United States Court of Appeals for the Fifth Circuit
Facts
Duffy was charged with transporting a stolen car across state lines. A key piece of evidence was a shirt found in the car bearing a laundry mark with the letters “D-U-F.” A witness testified to having observed the laundry mark on the shirt. Duffy argued that the best evidence rule required production of the shirt itself rather than testimony about the marking.
Issue
Whether the best evidence rule requires production of the shirt itself when a witness testifies about a simple laundry mark observed on it.
Holding
The Fifth Circuit held that the best evidence rule did not require production of the shirt because the shirt was not a “writing” for purposes of the rule, and the witness was testifying from personal knowledge of what he observed, not about the “contents” of a document.
Rule / Doctrine
The best evidence rule (now FRE 1002) applies to writings, recordings, and photographs when a party seeks to prove their content. The rule does not apply to every piece of tangible evidence; it is limited to inscriptions where the precise terms of the inscription are at issue. When a witness testifies from personal observation about a simple marking on an object, the rule does not require production of the object itself.
Significance
United States v. Duffy is the leading case defining the scope of the best evidence rule and establishing that it does not extend to every physical object bearing writing. It is regularly paired with Seiler v. Lucasfilm, Ltd. to illustrate the outer boundaries of FRE 1002.
