I have two cases going, one in Nebraska, one in Kansas. For each, I have a taped telephone call that I plan to try to use as evidence.
For the Nebraska case, the rule is as follows:
27-901. Rule 901. Requirement of authentication or identification; general provision; illustrations and examples; enumerated.
(1) The requirement of authentication or identification as a condition precedent to admissibility is satisfied by evidence sufficient to support a finding that the matter in question is what its proponent claims.
(2) By way of illustration only, and not by way of limitation, the following are examples of authentication or identification conforming with the requirements of this rule:
(f) Telephone conversations, by evidence that a call was made to the number assigned at the time by the telephone company to a particular person or business, if (i) in the case of a person, circumstances, including self-identification, show the person answering to be the one called, or (ii) in the case of a business, the call was made to a place of business and the conversation related to business reasonably transacted over the telephone.
However, I can't find anything similar for Kansas, or that it's not allowed at all.
I keep thinking about how, a few years back, there was a judge who died when he fell down an elevator shaft in an old building. That building was evidence, which is why he was there. Obviously the rules can't state specific rules pertaining to every single type of evidence that could possibly be offered in a court case.
If I'd have thought of this earlier this week, I would have tried to track down a copy of West's Lawyer's Guide to Kansas Evidence, 5th (Vol. 3, Kansas Law and Practice.) The public libraries in town don't have it, and everyplace else that might will be shut down for the weekend.
Hopefully, so I hopefully won't stew all weekend while thinking about it, I'm hoping someone here might know or be able to find out on this.
BTW--I'm aware of the sorts of hearsay objections my adversary can make on this. That's not what I'm concerned about right now, just how to authenticate it.
