Authorization
The process of proving that an item of evidence is what its proponet claims it to be
901(a): 3 general principles of authentication
- Evidence must be authenticated “in order to have it admitted”
- Evidence is suthenticated by showing that the item is what the proponet claims it to be
- The showing must be sufficent to support a finding
Evidence contesting the authenticity of an item that is already deemed authenticated and admissible, is
admissible
Limit on the power a party offering tangible evidence to decide on what they claim that evidence to be:
The claim must be consistany with establishing that the item is relevent
The burden of proving authenticity
sufficent to support a finding
meaning when:
evidence is “sufficent to support a finding”
so long a reasonable juror could conclude that the evidence is what it is claimed to be
Authentication is what equivilant to personal knowledge
Object
Authentication is also called
laying the foundation
Rule 901: Authentication
The list of examples is not
exhaustive, there may be more circumstances
The person who can authenticate is the person who has
the Personal Knowledge needed to provide authenticating testiony
FP (Facts Precieved) = FT (Facts that can be testified)
Authenticating a Photograph
Personal knowledge requirement varies based on
what the party offering the photograph claims it to be
A witness can authenticate a photograph by testifying that the photo is a
“fair and accurate dipiction” of a location
Authenticating a Photograph
When a witness authenticates a photo by saying that it is a “fair and accurate” depiction of the location, the photo is used as demonstrative evidence, if used to
help illustrate or explain witness testimony
If an item is unique in charater or appearance then
often a single witness can authenticate the item
