Section 706. Court Appointed Experts

(a) Appointment. The Court may on its 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 Court may appoint any expert witnesses agreed upon by the parties, and may appoint expert witnesses of its own selection. An expert witness shall not be appointed by the Court unless he consents to act. A witness so appointed shall be informed of his duties by the Court in writing, a copy of which shall be filed with the clerk, or at a conference in which the parties shall have opportunity to participate. A witness so appointed shall advise the parties of his findings, if any; his deposition may be taken by any party; and he may be called to testify by the Court or any party. He shall be subject to cross-examination by each party, including a party calling him as a witness.

(b) Compensation. Expert witnesses so appointed are entitled to reasonable compensation in whatever sum the Court may allow. The compensation thus fixed is payable from the Court fund, said fund to be reimbursed by the parties in such proportion and at such time as the Court directs, and thereafter charged in like manner as other costs.

(c) Disclosure of Appointment. In the exercise of its discretion, the Court may authorize disclosure to the jury of the fact that the Court appointed the expert witness.

(d) Parties' Experts of Own Selection. Nothing in this section limits the parties in calling expert witnesses of their own selection.
