Ala. R. Evid. 706
Advisory Committee's Notes
Section (a). Appointment. Section (a) recognizes the historic power of the trial court to appoint its own expert witnesses. See Alabama Great S. R.R. v. Hill, 90 Ala. 71, 8 So. 90 (1890). Compare J. Sink, The Unused Power of a Federal Judge to Call His Own Witnesses, 29 S. Cal. L. Rev. 195 (1956). The committee contemplates that this rule will make impartial experts more accessible to the courts. See Vt. R. Evid. 706 (reporter's notes to the effect that the rule "is a desirable one, providing an antidote to the most commonly noted weakness in the use of expert witnesses - the partisanship of experts chosen by the parties").
The appointment of an expert may be made upon the judge's own motion or upon that of a party. An expert witness appointed by the court is subject to the deposition procedure. All parties have the right to cross-examine such a witness. See Fed. R. Evid. 706 advisory committee's note.
Section (b). Compensation. Expert witnesses appointed by the court are to receive reasonable compensation as set by the court. The compensation should come from any source provided by law. If the law provides no other source for the compensation, then the judge may assess the compensation as costs to be paid by each party in such a proportion as the court deems fair.
Section (c). Disclosure of appointment. The fact that an expert has been appointed by the court is not to be disclosed to the jury. Such disclosure is precluded, whether by the court or by the parties themselves. See Elliott v. State, 48 Ala. App. 515, 266 So. 2d 318, cert. denied, 289 Ala. 742, 266 So. 2d 321 (1972). See also C. Gamble, McElroy's Alabama Evidence § 445.01 (4th ed. 1991).
Section (d). Parties' experts of own selection. Like its identical federal counterpart, section (d) provides that the trial court's exercise of its power to appoint and call an expert witness will not limit the parties in calling their own experts.
