(a) Appointment. Appointment of experts by the court is subject to the
availability of funds or the agreement of the parties concerning compensation.
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 the witness consents to
act. A witness so appointed shall be informed of the witness' 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 the witness' findings, if any; the witness'
deposition may be taken by any party, and the witness may be called to testify by
the court or any party. The witness shall be subject to cross-examination by each
party, including a party calling the witness.
(b) 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
(c) Parties' experts of own selection. Nothing in this rule limits the parties in
calling expert witnesses of their own selection.
