Federal Rule of Evidence 803(5) or a comparable State rule creates a hearsay exception for a memorandum or record concerning a matter about which a witness once had knowledge but now has insufficient recollection to enable the witness to testify fully and accurately, shown to have been made or adopted by the witness when the matter was fresh in the witness' memory and to reflect that knowledge correctly.

If Congress makes no changes, the following restyled Federal Rule of Evidence will go into effect on December 1, 2011:

Rule 803. Exceptions to the Rule Against Hearsay — Regardless of Whether the Declarant Is Available as a Witness

The following are not excluded by the rule against hearsay, regardless of whether the declarant is available as a witness:

....


(5) Recorded Recollection. A record that:

(A) is on a matter the witness once knew about but now cannot recall well enough to testify fully and accurately;

(B) was made or adopted by the witness when the matter was fresh in the witness’s memory; and

(C) accurately reflects the witness’s knowledge.

If admitted, the record may be read into evidence but may be received as an exhibit only if offered by an adverse party.
