N.Y. Comp. Codes R. & Regs. tit. 9, § 517.8
(4) A statement is not hearsay if:
(i) Prior statement by witness. The declarant testifies at the trial or hearing and is subject to cross-examination concerning the statement, and the statement is:
(ii) Admission by party-opponent. The statement is offered against a party and is:
(e) a statement by a co-conspirator of a party during the course and in furtherance of the conspiracy.
(b) Hearsay rule.
Hearsay is not admissible except as provided by these rules or by an Act of Congress applicable in trials by court-martial.
(c) Hearsay exceptions; availability of declarant immaterial.
The following are not excluded by the hearsay rule, even though the declarant is available as a witness:
(8) Public records and reports. Records, reports, statements, or data compilations, in any form, of public office or agencies, setting forth:
(24) Other exceptions. A statement not specifically covered by any of the foregoing exceptions but having equivalent circumstantial guarantees of trustworthiness, if the court determines that:
(iii) the general purposes of these rules and the interests of justice will best be served by admission of the statement into evidence.
However, a statement may not be admitted under this exception unless the proponent of it makes known to the adverse party sufficiently in advance of the trial or hearing to provide the adverse party with a fair opportunity to prepare to meet it, the intention to offer the statement and the particulars of it, including the name and address of the declarant.
(d) Hearsay exceptions; declarant unavailable.
(1) Definitions of unavailability. Unavailability as a witness includes situations in which the declarant:
(vi) is unavailable within the meaning of Military Law, section 130.49(d).
A declarant is not unavailable as a witness if the declarant's exemption, refusal, claim of lack of memory, inability, or absence is due to the procurement or wrongdoing of the proponent of the declarant's statement for the purpose of preventing the witness from attending or testifying.
(2) Hearsay exceptions. The following are not excluded by the hearsay rule if the declarant is unavailable as a witness.
(iv) Statement of personal or family history.
(v) Other exceptions. A statement not specifically covered by any of the foregoing exceptions but having equivalent circumstantial guarantees of trustworthiness, if the military judge determines that:
(c) the general purposes of these rules and the interest of justice will best be served by admission of the statement into evidence.
However, a statement may not be admitted under this exception unless the proponent of it makes known to the adverse party sufficiently in advance of the trial or hearing to provide the adverse party with a fair opportunity to prepare to meet it, the intention to offer the statement and the particulars of it, including the name and address of the declarant.
(e) Hearsay within hearsay.
Hearsay included within hearsay is not excluded under the hearsay rule if each part of the combined statements conforms with an exception to the hearsay rule provided in these rules.
(f) Attacking and supporting credibility of declarant.
When a hearsay statement, or a statement defined in Mil. R. Evid. 801(d)(2)(C), (D), or (E), has been admitted in evidence, the credibility of the declarant may be attacked, and if attacked may be supported, by any evidence which would be admissible for those purposes if declarant had testified as a witness. Evidence of a statement or conduct by the declarant at any time, inconsistent with the declarant's hearsay statement, is not subject to any requirement that the declarant may have been afforded an opportunity to deny or explain. If the party against whom a hearsay statement has been admitted calls the declarant as a witness, the party is entitled to examine the declarant on the statement as if under cross-examination.
