§ 501.730 Depositions upon oral examination.
(a) Procedure. Any party desiring to take the testimony of a witness by deposition shall make a written motion setting forth the reasons why such deposition should be taken including the specific reasons why the party believes the witness may be unable to attend or testify at the hearing; the name and address of the prospective witness; the matters concerning which the prospective witness is expected to be questioned; and the proposed time and place for the taking of the deposition.
(b) Required finding when ordering a deposition. In the discretion of the Administrative Law Judge, an order for deposition may be issued upon a finding that the prospective witness will likely give testimony material to the proceeding, that it is likely the prospective witness will be unable to attend or testify at the hearing because of age, sickness, infirmity, imprisonment or other disability, and that the taking of a deposition will serve the interests of justice.
