(a) Any defendant upon which a copy of a formal complaint is served shall answer such complaint in the manner prescribed under this section within 30 calendar days of service of the formal complaint by the complainant, unless otherwise directed by the Commission.(b) The answer shall advise the complainant and the Commission fully and completely of the nature of any defense, and shall respond specifically to all material allegations of the complaint. Every effort shall be made to narrow the issues in the answer. The defendant shall state concisely its defense to each claim asserted, admit or deny the averments on which the complainant relies, and state in detail the basis for admitting or denying such averment. General denials are prohibited. Denials based on information and belief are prohibited unless made in good faith and accompanied by a declaration or affidavit explaining the basis for the defendant's belief and why the defendant could not reasonably ascertain the facts from the complainant or any other source. If the defendant is without knowledge or information sufficient to form a belief as to the truth of an averment, the defendant shall so state and this has the effect of a denial. When a defendant intends in good faith to deny only part of an averment, the defendant shall specify so much of it as is true and shall deny only the remainder. The defendant may deny the allegations of the complaint as specific denials of either designated averments or paragraphs.(c) The answer shall include legal analysis relevant to the claims and arguments set forth therein.(d) Averments in a complaint or supplemental complaint filed pursuant to § 1.723(d) are deemed to be admitted when not denied in the answer.(e) Affirmative defenses to allegations in the complaint shall be specifically captioned as such and presented separately from any denials made in accordance with paragraph (b) of this section.(f) The answer shall include an information designation containing: (1) The name and, if known, the address and telephone number of each individual likely to have information relevant to the proceeding, along with the subjects of that information, excluding individuals otherwise identified in the complaint, answer, or exhibits thereto, and individuals employed by another party; and(2) A copy-or a description by category and location-of all relevant documents, electronically stored information, and tangible things that the disclosing party has in its possession, custody, or control, excluding documents submitted with the complaint or answer.(g) Failure to file an answer may be deemed an admission of the material facts alleged in the complaint. Any defendant that fails to file and serve an answer within the time and in the manner prescribed by this part may be deemed in default and an order may be entered against such defendant in accordance with the allegations contained in the complaint. 83 FR 44832 , Sept. 4, 2018
