in effect

Cal. Evidence Code - EVID § 730. Section 730.

When it appears to the court, at any time before or during the trial of an action, that expert evidence is or may be required by the court or by any party to the action, the court on its own motion or on motion of any party may appoint one or more experts to investigate, to render a report as may be ordered by the court, and to testify as an expert at the trial of the action relative to the fact or matter as to which the expert evidence is or may be required. The court may fix the compensation for these services, if any, rendered by any person appointed under this section, in addition to any service as a witness, at the amount as seems reasonable to the court. Nothing in this section shall be construed to permit a person to perform any act for which a license is required unless the person holds the appropriate license to lawfully perform that act.

Cal. Evidence Code - EVID § 731. Section 731.

(a) (1) In all criminal actions and juvenile court proceedings, the compensation fixed under Section 730 shall be a charge against the county in which the action or proceeding is pending and shall be paid out of the treasury of that county on order of the court. (2) Notwithstanding paragraph (1), if the expert is appointed for the court’s needs, the compensation shall be a charge against the court. (b) In any county in which the superior court so provides, the compensation fixed under Section 730 for medical experts appointed for the court’s needs in civil actions shall be a charge against the court. In any county in which the board of supervisors so provides, the compensation fixed under Section 730 for medical experts appointed in civil actions, for purposes other than the court’s needs, shall be a charge against and paid out of the treasury of that county on order of the court. (c) Except as otherwise provided in this section, in all civil actions, the compensation fixed under Section 730 shall, in the first instance, be apportioned and charged to the several parties in a proportion as the court may determine and may thereafter be taxed and allowed in like manner as other costs.

Cal. Evidence Code - EVID § 732. Section 732.

Any expert appointed by the court under Section 730 may be called and examined by the court or by any party to the action. When such witness is called and examined by the court, the parties have the same right as is expressed in Section 775 to cross-examine the witness and to object to the questions asked and the evidence adduced.

Cal. Evidence Code - EVID § 733. Section 733.

Nothing contained in this article shall be deemed or construed to prevent any party to any action from producing other expert evidence on the same fact or matter mentioned in Section 730; but, where other expert witnesses are called by a party to the action, their fees shall be paid by the party calling them and only ordinary witness fees shall be taxed as costs in the action.
