(a) Service and content. In the interest of expedition, any participant may serve upon any other participant a written request for the admission of any relevant, unprivileged facts, including the genuineness of any documents or exhibits to be presented in the hearing. The admission shall be for purposes of the pending proceeding only. The participant requesting the admission shall file its request with the Commission in conformance with subpart B to part 3010 of this chapter.

(b) Answers. (1) A matter for which admission is requested shall be separately set forth in the request and is deemed admitted unless, within seven days after the request is filed, or within such other period as may be established by the Commission or presiding officer, the respondent files a written answer or motion to be excused from answering pursuant to paragraph (c) of this section. Answers to requests for admission shall be filed with the Commission in conformance with subpart B to part 3010 of this chapter.

(2) If the answer filed by the respondent does not admit a matter asserted in the participant's request, it must either specifically deny the matter or explain in detail why it cannot truthfully admit or deny the asserted matter. When good faith requires, the respondent must admit a portion of the asserted matter and either deny or qualify the remaining portion of such asserted matter. Lack of knowledge for failing to admit or deny can be invoked only after reasonable inquiry if the information already possessed or reasonably obtainable is insufficient to enable an admission or denial.

(3) Grounds for objection to requests for admission must be stated. Objections cannot be based solely upon the ground that the request presents a genuine issue for trial.

(c) Motion to be excused from answering. A respondent may, in lieu of answering a request for admission, file a motion pursuant to § 3020.105(b) to be excused from answering.
