(a) Required or permitted.
(1) Any respondent to a complaint or order to show cause must make an answer, unless the Commission orders otherwise.
(2) An answer may not be made to a protest, an answer, a motion for oral argument, or a request for rehearing, unless otherwise ordered by the decisional authority. A presiding officer may prohibit an answer to a motion for interlocutory appeal. If an answer is not otherwise permitted under this paragraph, no responsive pleading may be made.
(3) An answer may be made to any pleading, if not prohibited under paragraph (a)(2) of this section.
(4) An answer to a notice of tariff or rate examination must be made in accordance with the provisions of such notice.

(c) Contents.
(1) An answer must contain a clear and concise statement of:
(i) Any disputed factual allegations; and
(ii) Any law upon which the answer relies.
(2) When an answer is made in response to a complaint, an order to show cause, or an amendment to such pleading, the answerer must, to the extent practicable:
(i) Admit or deny, specifically and in detail, each material allegation of the pleading answered; and
(ii) Set forth every defense relied on.
(3) General denials of facts referred to in any order to show cause, unsupported by the specific facts upon which the respondent relies, do not comply with paragraph (a)(1) of this section and may be a basis for summary disposition under Rule 217, unless otherwise required by statute.
(4) An answer to a complaint must include documents that support the facts in the answer in possession of, or otherwise attainable by, the respondent, including, but not limited to, contracts and affidavits. An answer is also required to describe the formal or consensual process it proposes for resolving the complaint.
(5) When submitting with its answer any request for privileged treatment of documents and information in accordance with this chapter, a respondent must provide a public version of its answer without the information for which privileged treatment is claimed and its proposed form of protective agreement to each entity that has either been served pursuant to § 385.206(c) or whose name is on the official service list for the proceeding compiled by the Secretary.

(i) If a motion requests an extension of time or a shortened time period for action, then answers to the motion to extend or shorten the time period shall be made within 5 days after the motion is filed, unless otherwise ordered.
(ii) [Reserved]
(2) Any answer to a pleading or amendment to a pleading, other than a complaint or an answer to a motion under paragraph (d)(1) of this section, must be made:
