3001.26—Interrogatories for purpose of discovery.

(a) Service and contents. In the interest of expedition and limited to information which appears reasonably calculated to lead to the discovery of admissible evidence, any participant may propound to any other participant in a proceeding written, sequentially numbered interrogatories, by witness, requesting nonprivileged information relevant to the subject matter in such proceeding, to be answered by the participant served, who shall furnish such information as is available to the participant. A participant through interrogatories may require any other participant to identify each person whom the other participant expects to call as a witness at the hearing and to state the subject matter on which the witness is expected to testify. The participant propounding the interrogatories shall file them with the Commission in conformance with §§ 3001.9 through 3001.12. Follow-up interrogatories to clarify or elaborate on the answer to an earlier discovery request may be filed after the initial discovery period ends. They must be filed within seven days of receipt of the answer to the previous interrogatory unless extraordinary circumstances are shown.
(b) Answers. Answers to discovery requests shall be prepared so that they can be incorporated as written cross-examination. Each answer shall begin on a separate page, identify the individual responding and the relevant testimony number, if any, the participant who asked the question, and the number and text of the question. Each interrogatory shall be answered separately and fully in writing, unless it is objected to, in which event the reasons for objection shall be stated in the manner prescribed by paragraph (c) of this section. The participant responding to the interrogatories shall file the answers in conformance with §§ 3001.9 through 3001.12 within 14 days of the filing of the interrogatories or within such other period as may be fixed by the Commission or presiding officer, but before the conclusion of the hearing.
(c) Objections. In the interest of expedition, the bases for objection shall be clearly and fully stated. If objection is made to part of an interrogatory, the part shall be specified. A participant claiming privilege shall identify the specific evidentiary privilege asserted and state the reasons for its applicability. A participant claiming undue burden shall state with particularity the effort that would be required to answer the interrogatory, providing estimates of cost and work hours required, to the extent possible. An interrogatory otherwise proper is not necessarily objectionable because an answer would involve an opinion or contention that relates to fact or the application of law to fact, but the Commission or presiding officer may order that such an interrogatory need not be answered until a prehearing conference or other later time. Objections shall be filed with the Commission in conformance with §§ 3001.9 through 3001.12 within 10 days of the filing of the interrogatories.
(d) Motions to compel responses to discovery. Motions to compel a more responsive answer, or an answer to an interrogatory to which an objection was interposed, should be filed within 14 days of the answer or objection to the discovery request. The text of the discovery request, and any answer provided, should be provided as an attachment to the motion to compel. Participants who have objected to interrogatories which are the subject of a motion to compel shall have seven days to answer. Answers will be considered supplements to the arguments presented in the initial objection.
(e) Compelled answers. The Commission, or the presiding officer, upon motion of any participant to the proceeding, may compel a more responsive answer, or an answer to an interrogatory to which an objection has been raised if the objection is found not to be valid, or may compel an additional answer if the initial answer is found to be inadequate. Such compelled answers shall be filed in conformance with §§ 3001.9 through 3001.12 within seven days of the date of the order compelling an answer or within such other period as may be fixed by the Commission or presiding officer, but before the conclusion of the hearing.
(f) Supplemental answers. The individual or participant who has answered interrogatories is under the duty to seasonably amend a prior answer if he/she obtains information upon the basis of which he/she knows that the answer was incorrect when made or is no longer true. Participants shall serve supplemental answers to update or to correct responses whenever necessary, up until the date the answer could have been accepted into evidence as written cross-examination. Participants filing supplemental answers shall indicate whether the answer merely supplements the previous answer to make it current or whether it is a complete replacement for the previous answer.
(g) Orders. The Commission or the presiding officer may order that any participant or person shall answer on such terms and conditions as are just and may for good cause make any protective order, including an order limiting or conditioning interrogatories, as justice requires to protect a participant or person from undue annoyance, embarrassment, oppression, or expense.
