allcomplaints and amended complaintsshall be filed.An original and one copyof all other pleadings shall be filed.68.406Service.(a)The Commission will serve a copyof any complaint or amended com-plaint filed with it,together with a no-tice of the filing of the complaint.Such notice shall call upon the defend-ant to satisfy or answer the complaintin writing within the time specified insaid notice of complaint.(b)All subsequent pleadings andbriefs shall be served by the filingparty on all other parties to the pro-ceeding in accordance with the require-ments of 1.47.Proof of such serviceshall also be made in accordance withthe requirements of said section.68.408Answers to complaints andamended complaints.Any party upon whom a copy of acomplaint or amended complaint isserved under this subpart shall servean answer within the time specified bythe Commission in its notice of com-plaint.The answer shall advise the par-ties and the Commission fully and com-pletely of the nature of the defense,and shall respond specifically to allmaterial allegations of the complaint.In cases involving allegations of harm,the answer shall indicate what actionhas been taken or is proposed to betaken to stop the occurrence of suchharm,both in terms of future produc-tion and with reference to articles inthe possession of distributors,sellers,and users.Collateral or immaterialissues shall be avoided in answers andevery effort should be made to narrowthe issues.Matters alleged as affirma-tive defenses shall be separately statedand numbered.Any defendant failingto file and serve an answer within thetime and in the manner prescribed maybe deemed in default.68.410Replies to answers or amend-ed answers.Within 10 days after service of an an-swer or an amended answer,a com-plainant may serve a reply which shallbe responsive to matters contained insuch answer or amended answer andshall not contain new matters.Failureto reply will not be deemed an admis-sion of any allegation contained insuch answer or amended answer.68.412Defective pleadings.Any pleading filed in a complaintproceeding not in substantial con-formity with the requirements of theapplicable rules in this part may bedismissed.68.414Hearing aid-compatibility:En-forcement.Enforcement of 68.4 and 68.112 ishereby delegated to those states whichadopt those sections and provide fortheir enforcement.The procedures fol-lowed by a state to enforce those sec-tions shall provide a 30-day period aftera complaint is filed,during which timestate personnel shall attempt to re-solve a dispute on an informal basis.Ifa state has not adopted or incorporated68.4 and 68.112,or failed to act within6 months from the filing of a complaintwith the state public utility commis-sion,the Commission will accept suchcompliants.A written notification tothe complainant that the state believesaction is unwarranted is not a failureto act.49 FR 1368,Jan.11,1984Subpart FConnectorsSOURCE:41 FR 28699,July 12,1976,unlessotherwise
