§ 2200.52 General provisions governing discovery.
(a) General—(1) Methods and limitations. In conformity with these rules, any party may, without leave of the Commission or the Judge, obtain discovery by one or more of the following methods:
(i) Production of documents or things or permission to enter upon land or other property for inspection and other purposes to the extent provided in § 2200.53;
(ii) Requests for admission to the extent provided in § 2200.54; and
(iii) Interrogatories to the extent provided in § 2200.55.
(iv) Discovery is not available under these rules through depositions except to the extent provided in § 2200.56.
(v) In the absence of a specific provision, discovery procedures shall be in accordance with the Federal Rules of Civil Procedure, except that the provisions of Federal Rule of Civil Procedure 26(a) do not apply to Commission proceedings. This exception does not preclude any prehearing disclosures (including disclosure of expert testimony and written reports) directed in a scheduling order entered under § 2200.51.
(2) Time for discovery. A party may initiate all forms of discovery in conformity with these Rules at any time after the filing of the first responsive pleading or motion that delays the filing of an answer, such as a motion to dismiss. Discovery shall be initiated early enough to permit completion of discovery no later than 14 days prior to the date set for hearing, unless the Judge orders otherwise.
(3) Service of discovery documents. Every document relating to discovery required to be served on a party shall be served on all parties.
(4) Stipulations about discovery procedures. Unless the Commission or the Judge orders otherwise, the parties may stipulate that:
(i) A deposition may be taken before any person, at any time or place, on any notice, and in the manner specified—in which event it may be used in the same way as any other deposition; and
(ii) Other procedures governing or limiting discovery may be modified—but a stipulation extending the time for any form of discovery must be approved by the Commission or the Judge if it would interfere with the time set forth for completing discovery, for hearing a motion, or for hearing.
(b) Scope of discovery. The information or response sought through discovery may concern any matter that is not privileged and that is relevant to the subject matter involved in the pending case and proportional to the needs of the case, considering the importance of the issues at stake, the parties' relative access to relevant information, the parties' resources, the importance of the discovery in resolving the issues, and whether the burden or expense of the proposed discovery outweighs its likely benefit. Information within this scope of discovery need not be admissible in evidence to be discoverable.
