4 - Tangible Evidence Flashcards
What is tangible evidence? What does it include? (2)
Tangible evidence is evidence that is not testimonial in nature, and includes both documentary evidence and real evidence.
What is real evidence? When is it admissible?
Real evidence is evidence in the form of a physical object (e.g., a gun, torn clothing, an injured foot, a sound recording). Real evidence is admissible as long as its value is not outweighed by the danger of unfair prejudice.
All tangible evidence must be …? FRE?
All tangible evidence must be authenticated (i.e., there must be sufficient evidence to support a finding that the thing is what its proponent claims it is) before it can be admitted into evidence. Fed. R. Evid. 901(a).
What is authentication?
There must be sufficient evidence to support a finding that the thing is what its proponent claims it is.
How may real evidence be authenticated? (3)
By testimony of personal knowledge showing familiarity with the object, by distinctive markings or characteristics, or by chain of custody.
What about “chain of custody” and authentication?
Authentication by chain of custody must be used with respect to evidence that could easily be tampered with or confused with a similar item, such as a blood sample. The witness testifying must account for the whereabouts of the item from the time it was obtained up until the trial.
What are reproductions? (4) How can they be authenticated? Must there be personal testimony from the creator?
When reproductions (e.g., photographs, diagrams, maps, movies) are used to illustrate testimony, they may be authenticated by testimony of a witness with personal knowledge that the object accurately depicts what it its proponent claims it does. It is generally not necessary to call the person who created the reproduction to authenticate it.
How can x-rays be authenticated? (4)
X-ray pictures cannot be authenticated by the testimony of a witness that it is an accurate depiction of the facts. To authenticate an x-ray picture it must be shown that an accurate process was used, the machine used was working properly, and the operator of the machine was qualified to operate it. The chain of custody of the x-ray picture must also be established.
What standard must documents be authenticated by?
Most documents must be authenticated by sufficient proof to support a jury finding that the document is genuine. (This is a standard below preponderance of the evidence.)
What are common methods of authentication of documentary evidence? (3)
Common methods of authentication include stipulation by the opposing party, testimony of an eyewitness, and handwriting verification.
What is an ancient document, and what does it take for it to be authentic (3)? FRE?
A document or data compilation, including data stored electronically, that is (i) at least 20 years old, (ii) in a condition unlikely to create suspicion as to its authenticity, and {iii) was found in a place where it would likely be if it were authentic, is considered to be authentic. Fed. R. Evid. 901(b)(8).
What is the reply letter doctrine?
A document may be authenticated by evidence that it was written in response to a communication, so long as it is unlikely, based on the contents, that it was written by someone other than the recipient of the first communication.
What are the two methods by which handwriting verification may be used to authenticate a writing?
Comparison and non-expert opinion
What about comparison and handwriting verification? FRE?
An expert witness or the trier of fact (i.e., the jury) may compare the writing in question with another writing that has been proven to be genuine in order to determine the authenticity of the writing in question. Fed. R. Evid. 901(b)(3).
What about lay witness testimony and handwriting verification? Except? FRE?
A lay witness with personal knowledge of the claimed author’s handwriting may testify as to whether the document is in that person’s handwriting. The lay witness must not have become familiar with the handwriting for the purposes of litigation. Fed. R. Evid. 901(b)(2).
