Evidence Law: Witnesses: Hearsay evidence + Recorded recollection + Dead man's statute

Hearsay evidence, in a legal forum, is testimony from a witness under oath who is reciting an out-of-court statement, content of which is being offered to prove the truth of the matter asserted.

In most courts, hearsay evidence is inadmissible (the "Hearsay Evidence Rule") unless an exception to the Hearsay Rule applies.

For example, to prove that Tom was in town, the attorney asks a witness, "What did Susan tell you about Tom being in town?" Since the witness's answer will rely on an out-of-court statement that Susan made, if Susan is unavailable for cross-examination, the answer is hearsay. A justification for the objection is that the person who made the statement is not in court and thus is insulated from cross-examination. Note, however, that if the attorney asking the same question is not trying to prove the truth of the assertion about Tom being in town but the fact that Susan said the specific words, it may be acceptable. For example, it would be acceptable to ask a witness what Susan told them about Tom in a defamation case against Susan because now the witness is asked about the opposing party's statement that constitutes a verbal act.

The hearsay rule does not exclude the evidence if it is an operative fact. Language of commercial offer and acceptance is also admissible over a hearsay exception because the statements have independent legal significance.

Double hearsay is a hearsay statement that contains another hearsay statement itself. For example, a witness wants to testify that "a very reliable man informed me that Wools-Sampson told him". The statements of the very reliable man and Wools-Sampson are both hearsay submissions on the part of the witness, and the second hearsay (the statement of Wools-Sampson) depends on the first (the statement of the very reliable man). In a court, both layers of hearsay must be found separately admissible. In this example, the first hearsay also comes from an anonymous source, and the admissibility of an anonymous statement depends upon the discharge of an additional legal burden of proof.

Many jurisdictions that generally disallow hearsay evidence in courts permit the more widespread use of hearsay in non-judicial hearings.

A recorded recollection (sometimes referred to as a prior recollection recorded), in the law of evidence, is an exception to the hearsay rule which allows witnesses to testify to the accuracy of a recording or documentation of their own out-of-court statement based on their recollection of the circumstances under which the statement was recorded or documented - even though the witness does not remember the events attested to in the statement. It is sufficient that the witness is able to testify to having made the recording, and to having written an accurate statement at that time.

A dead man's statute, also known as a dead man act or dead man's rule, is a statute designed to prevent perjury in a civil case by prohibiting a witness who is an interested party from testifying about communications or transactions with a deceased person (a "decedent") against the decedent unless there is a waiver.

This prohibition applies only against a witness who has an interest in the outcome of the case and applies only where that witness is testifying for his own interests and against the interests of the decedent. Furthermore, the restriction only exists in civil cases, never in criminal cases.
