28.26—Witness fees.

The costs involved in the appearance of witnesses in any Board proceeding shall be allocated as follows:
(c) Witnesses who are not covered by paragraphs (a) or (b) of this section are entitled to the same witness fees as those paid to subpoenaed witnesses under 28 U.S.C. 1821. The fees shall be paid, in the first instance, by the party requesting the appearance of the witness, subject to a subsequent decision otherwise in accordance with § 28.89, concerning the award of attorneys fees and costs. Such fees shall be tendered to the witness at the time the subpoena is served, or, when the witness appears voluntarily, at the time of appearance. A federal agency or corporation is not required to tender witness fees in advance. Payment of travel and per diem expenses shall be governed by applicable law and regulation.
