28 CFR § 68.43 - Exhibits.

(a) Identification. All exhibits offered in evidence shall be numbered and marked with a designation identifying the party or intervenor by whom the exhibit is offered.

(b) Exchange of exhibits. When written exhibits are offered in evidence, one copy must be furnished to each of the parties at the hearing, and two copies to the Administrative Law Judge, unless the parties previously have been furnished with copies or the Administrative Law Judge directs otherwise. If the Administrative Law Judge has not fixed a time for the exchange of exhibits, the parties shall exchange copies of exhibits at the earliest practicable time, preferably before the hearing or, at the latest, at the commencement of the hearing.

(c) Substitution of copies for original exhibits. The Administrative Law Judge may permit a party to withdraw original documents offered in evidence and substitute true copies in lieu thereof.
