39 C.F.R. §§ 3010.311–3010.313

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 party may propound to any other party in a proceeding written, sequentially numbered interrogatories, by witness, requesting non-privileged information relevant to the subject matter and reasonably calculated to lead to the discovery of admissible evidence in such proceeding, to be answered by the party served, who shall furnish such information as is available to the requesting party. A party through interrogatories may require any other party to identify each person whom the other party expects to call as a witness at the hearing and to state the subject matter on which the witness is expected to testify. The party propounding the interrogatories shall file them with the Commission and serve them on the answering party. 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.

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 party 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 party responding to the interrogatories shall file the answers with the Commission and serve them on the requesting party 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.

Objections. In the interest of expedition, the grounds for every objection shall be clearly and fully stated. If an objection is made to part of an interrogatory, the part shall be specified. A party claiming privilege shall identify the specific evidentiary privilege asserted and state the reasons for its applicability. A party 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 and served on the requesting party within ten days of the filing of the interrogatories. Any ground not stated in a timely objection is waived unless excused by the Commission or presiding officer for good cause shown.

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. Parties 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.

Compelled answers. The Commission, or the presiding officer, upon motion of any party 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 overruled, or may compel an additional answer if the initial answer is found to be inadequate. Such compelled answers shall be filed with the Commission and served on the compelling party 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.

Supplemental answers. The individual or party who has answered interrogatories is under the duty to seasonably amend a prior answer if the individual or party obtains information upon the basis of which the individual or party knows that the answer was incorrect when made or is no longer true. Parties 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. Parties 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.

Orders. The Commission or the presiding officer may order that any party 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 party or person from undue annoyance, embarrassment, oppression, or expense.

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 party may serve on any other party to the proceeding a request to produce and permit the party making the request, or someone acting on behalf of the requesting party or the requesting party's agent to inspect and copy any designated documents or things that constitute or contain matters, not privileged, that are relevant to the subject matter involved in the proceeding or reasonably calculated to lead to the discovery of admissible evidence and that are in the custody or control of the party to whom the request is addressed. The request shall set forth the items to be inspected either by individual item or category, and describe each item and category with reasonable particularity, and shall specify a reasonable time, place and manner of making inspection. The party requesting the production of documents or things shall file its request with the Commission and serve the request on the responding party.

Answers. The party responding to the request shall file an answer with the Commission and serve the answer on the requesting party within 14 days after the request is filed, or within such other period as may be fixed by the Commission or presiding officer. The answer shall state, with respect to each item or category, that inspection will be permitted as requested unless the request is objected to pursuant to paragraph (c) of this section. The responding party may produce copies of documents or of electronically stored information in lieu of permitting inspection. Production must be completed no later than the time for inspection specified in the request unless good cause is shown.

Objections. In the interest of expedition, the grounds for objection shall be clearly and fully stated. If an objection is made to part of an item or category, the part shall be specified. Any objection must state whether any responsive materials are being withheld on the basis of that objection. A party claiming privilege shall identify the specific evidentiary privilege asserted and state with particularity the reasons for its applicability. A party claiming undue burden shall state with particularity the effort that would be required to answer the request, providing estimates of cost and work hours required, to the extent possible. Objections shall be filed with the Commission and served on the requesting party within ten days of the request for production. The responding party may state an objection to a request to produce electronically stored information. If it objects to the form of the documents or things requested (or if no form was specified in the request), the responding party must state the form or forms it intends to use to produce the requested information.

Motions to compel requests for production of documents or things for purposes of discovery. Motions to compel shall 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. Parties who have objected to requests for production of documents or things 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.

Compelled answers. Upon motion of any party to the proceeding to compel a response to discovery, as provided in paragraph (d) of this section, the Commission or the presiding officer may compel production of documents or things to which an objection is overruled. Such compelled documents or things shall be made available to the party making the motion within seven days of the date of the order compelling production or within such other period as may be fixed by the Commission or presiding officer, but before the conclusion of the hearing.

Orders and rulings. The Commission or the presiding officer may direct any party or person to respond to a request for inspection on such terms and conditions as are just and may for good cause impose any protective conditions, including limitations or preconditions for inspections, as justice requires to protect a party or person from undue annoyance, embarrassment, oppression, or expense.

Service and content. In the interest of expedition, any party may serve upon any other party a written request for the admission, for purposes of the pending proceeding only, of any relevant, unprivileged facts, including the genuineness of any documents or exhibits to be presented in the hearing. Each requested admission shall be set forth separately and shall be deemed admitted unless within 14 days after the request is filed (or such other period as may be fixed by the Commission or presiding officer) the party to whom the request is directed files a written answer denying the requested admission pursuant to paragraph (c) of this section or objecting pursuant to paragraph (d) of this section. The party requesting an admission shall file its request with the Commission and serve the request on the responding party.

Answers. Answers that fail to admit a matter as requested shall specifically deny the matter or set forth in detail the reasons why the answering party cannot truthfully admit or deny the matter. A denial shall fairly meet the substance of the requested admission. When a party qualifies an answer or denies only a part of the admission requested, the party shall specify so much of the requested admission as is true and qualify or deny the remainder. A failure to admit or deny for lack of information or knowledge shall not be made unless the responding party states that it has made a reasonable inquiry and that information known or readily obtainable by the party is insufficient to enable the party to admit or deny. A party who answers a request for admission shall file its answer with the Commission and serve the answer on the requesting party.

Objections. If an objection is made, the grounds for such objection shall be clearly and fully stated. If an objection is made to part of an item, the part to which an objection is made shall be specified. A party claiming privilege shall identify the specific evidentiary privilege asserted and state the reasons for its applicability. A party claiming undue burden shall state with particularity the effort that would be required to answer the request, providing estimates of cost and work hours required to the extent possible. Objections shall be filed with the Commission and served on the requesting party, within ten days of the request for admissions.

Motions to compel responses to requests for admissions. The party who has requested an admission may move to determine the sufficiency of the answers or objections. Motions to compel a more responsive answer, or an answer to a request to which an objection was interposed, shall be filed within 14 days of the answer or objection to the request for admissions. The text of the request for admissions, and any answer provided, should be provided as an attachment to the motion to compel. Parties who have objected to requests for admissions which are the subject of a motion to compel shall have seven days to file a response. Responses will be considered supplements to the arguments presented in the initial objection.

Compelled answers. The Commission or the presiding officer may compel answers to a request for admissions to which an objection has been raised if the objection is overruled. Such compelled answers shall be filed with the Commission and served on the requesting party within seven days of the date of the order compelling production or within such other period as may be fixed by the Commission or the presiding officer, but before the conclusion of the hearing. If the Commission or presiding officer determines that an answer does not comply with the requirements of this rule, it may order either that the matter is admitted or that an amended answer be filed.
