Code of Federal Regulations Title 29. Labor § 29.18.706 Judge appointed experts

(a) Appointment. The judge may on the judge's own motion or on the motion of any party enter an order to show cause why expert witnesses should not be appointed, and may request the parties to submit nominations. The judge may appoint any expert witnesses agreed upon by the parties, and may appoint expert witnesses of the judge's own selection. An expert witness shall not be appointed by the judge unless the witness consents to act. A witness so appointed shall be informed of the witness' duties by the judge in writing, a copy of which shall be filed with the clerk, or at a conference in which the parties shall have an opportunity to participate. A witness so appointed shall advise the parties of the witness' findings, if any;  the witness' deposition may be taken by any party;  and the witness may be called to testify by the judge or any party. The witness shall be subject to cross-examination by each party, including a party calling the witness.

(b) Compensation. Expert witnesses so appointed are entitled to reasonable compensation in whatever sum the judge may allow. The compensation thus fixed is payable from funds which may be provided by law in hearings involving just compensation under the fifth amendment. In other hearings the compensation shall be paid by the parties in such proportion and at such time as the judge directs, and thereafter charged in like manner as other costs.

(c) Parties' experts of own selection. Nothing in this rule limits the parties in calling expert witnesses of their own selection.
