(a) General rules.

(1) If a witness will not be available for the hearing, a party may apply in accordance with the procedures set forth in paragraph (a)(2) of this section, to the administrative law judge for the issuance of a subpoena, including a subpoena duces tecum, requiring the attendance of the witness at a deposition. The administrative law judge may issue a deposition subpoena under this section upon showing that:

(i) The witness will be unable to attend or may be prevented from attending the hearing because of age, sickness or infirmity, or will otherwise be unavailable;

(ii) The witness' unavailability was not procured or caused by the subpoenaing party;

(iii) The testimony is reasonably expected to be material; and

(iv) Taking the deposition will not result in any undue burden to any other party and will not cause undue delay of the proceeding.

(2) The application must contain a proposed deposition subpoena and a brief statement of the reasons for the issuance of the subpoena. The subpoena must name the witness whose deposition is to be taken and specify the time and place for taking the deposition. A deposition subpoena may require the witness to be deposed at any place within the country in which that witness resides or has a regular place of employment or such other convenient place as the administrative law judge shall fix.

(3) Any requested subpoena that sets forth a valid basis for its issuance must be promptly issued, unless the administrative law judge on his or her own motion, requires a written response or requires attendance at a conference concerning whether the requested subpoena should be issued.

(4) The party obtaining a deposition subpoena is responsible for serving it on the witness and for serving copies on all parties. Unless the administrative law judge orders otherwise, no deposition under this section shall be taken on fewer than ten days' notice to the witness and all parties. Deposition subpoenas may be served in any state, territory, possession of the United States, or the District of Columbia, on any person or company doing business in any state, territory, possession of the United States, or the District of Columbia, or as otherwise permitted by law.

(b) Objections to deposition subpoenas.

(1) The witness and any party who has not had an opportunity to oppose a deposition subpoena issued under this section may file a motion with the administrative law judge to quash or modify the subpoena prior to the time for compliance specified in the subpoena, but not more than ten days after service of the subpoena.

(2) A statement of the basis for the motion to quash or modify a subpoena issued under this section must accompany the motion. The motion must be served on all parties.

(c) Procedure upon deposition.

(1) Each witness testifying pursuant to a deposition subpoena must be duly sworn, and each party shall have the right to examine the witness. Objections to questions or documents must be in short form, stating the grounds for the objection. Failure to object to questions or documents is not deemed a waiver except where the ground for the objection might have been avoided if the objection had been timely presented. All questions, answers, and objections must be recorded.

(2) Any party may move before the administrative law judge for an order compelling the witness to answer any questions the witness has refused to answer or submit any evidence the witness has refused to submit during the deposition.

(3) The deposition must be subscribed by the witness, unless the parties and the witness, by stipulation, have waived the signing, or the witness is ill, cannot be found, or has refused to sign. If the deposition is not subscribed by the witness, the court reporter taking the deposition shall certify that the transcript is a true and complete transcript of the deposition.

(d) Enforcing subpoenas. If a subpoenaed person fails to comply with any order of the administrative law judge which directs compliance with all or any portion of a deposition subpoena under paragraph (b) or (c)(2) of this section, the subpoenaing party or other aggrieved party may, to the extent authorized by applicable law, apply to an appropriate United States district court for an order requiring compliance with the portions of the subpoena that the administrative law judge has ordered enforced. A party's right to seek court enforcement of a deposition subpoena in no way limits the sanctions that may be imposed by the administrative law judge on a party who fails to comply with or procures a failure to comply with, a subpoena issued under this section.
