The Commission shall conduct proceedings on the record with the opportunity for a hearing subject to this subpart whenever:

(a) The Commission determines that a complaint filed under part 3022 of this chapter raises one or more material issues of fact or law in accordance with § 3022.30 of this chapter and a proceeding on the record with the opportunity for a hearing is necessary;

(b) The Commission determines that the streamlined procedures in part 3020 of this chapter applicable to a Postal Service request to change the nature of postal services which will generally affect service on a nationwide or substantially nationwide basis are not appropriate; or

(c) The Commission in the exercise of its discretion determines it is appropriate.

Whenever the Commission determines that a proceeding will be held on the record with an opportunity for a hearing under this part, it shall publish notice of the proceeding in the Federal Register pursuant to § 3010.151.

(a) Initiation and purposes. The Commission or the presiding officer, if one has been appointed, may direct the parties in a proceeding to appear for a prehearing conference for the purposes of considering all possible ways of expediting the proceeding, including those in paragraph (e) of this section. Prehearing conference procedures shall be rigorously pursued by all parties.

(b) Who presides. The presiding officer, if one has been designated, shall preside over prehearing conferences. If a presiding officer has not been designated or is otherwise unavailable for a prehearing conference, then the ranking Commissioner in attendance shall be considered the presiding officer for that conference. The presiding officer shall open and close each prehearing conference session and shall be responsible for controlling the conduct of the conference.

(c) Informal off-the-record procedures. In order to make the prehearing conference as effective as possible, the presiding officer may direct that conferences be held off the record, without the presiding officer present. Informal off-the-record conferences shall be presided over by the Public Representative or such other person as the parties may select. At off-the-record conferences, parties shall be expected to reach agreement on those matters, which will expedite the proceeding, including the matters specified in the notice of the prehearing conference, in the ruling of the presiding officer directing that the off-the-record conference be held, and in paragraph (e) of this section. A report on the results of off-the-record conferences shall be made to the presiding officer on the record at a time specified by the presiding officer. The presiding officer shall then determine the further prehearing procedures, if any, to be followed.

(d) Required preparation and cooperation of all parties. All parties in any proceeding before the Commission are required and expected to come to prehearing conferences fully prepared to discuss in detail and resolve all matters, such as those specified in paragraph (e) of this section, in the notice of the prehearing conference, and in such other notice or agenda as may have been issued by the Commission or the presiding officer. All parties are required and expected to cooperate fully at all stages of the proceeding to achieve these objectives through thorough advance preparation for the prehearing conference, including informal communications between the parties, requests for discovery and appropriate discovery procedures at the earliest possible time and no later than at the prehearing conference, and the commencement of preparation of evidence and cross-examination. The failure of any party to appear at the prehearing conference or to raise any matters that could reasonably be anticipated and resolved at the prehearing conference shall not be permitted to unduly delay the progress of the proceeding and shall constitute a waiver of the rights of the party with regard thereto, including all objections to the agreements reached, actions taken, or rulings issued by the presiding officer with regard thereto.

(e) Matters to be pursued. At the prehearing conference, the presiding officer and the parties shall consider and resolve such matters as:

(1) The definition and simplification of the issues, including any appropriate explanation, clarification, or amendment of any proposal, filing, evidence, complaint or other pleading filed by any party;

(2) Arrangements for timely completion of discovery from the Postal Service or any other party of information regarding any issues in the proceeding, prior filings, evidence or pleadings of any party;

(3) Procedures for timely discovery with regard to any future evidentiary filings of any party;

(4) Stipulations, admissions or concessions as to evidentiary facts, and agreements as to documentary matters, exhibits and matters of official notice, which will avoid unnecessary proof or dispute;

(5) The possible grouping of parties with substantially like interests for purposes of presenting evidence, making and arguing motions and objections, cross-examining witnesses, filing briefs, and presenting oral argument to the Commission or presiding officer;

(6) Disclosure of the number, identity and qualifications of witnesses, and the nature of their testimony, particularly with respect to the policies of the Act and, as applicable according to the nature of the proceeding;

(7) Limitation of the scope of the evidence and the number of witnesses in order to eliminate irrelevant, immaterial, or cumulative and repetitious evidence;

(8) Procedures to direct and control the use of discovery prior to the hearing and submission of written testimony and exhibits on matters in dispute so as to restrict to a bare minimum the amount of hearing time required for oral cross-examination of witnesses;

(9) Division of the proceeding where practicable into two or more phases for separate and, if advisable, simultaneous hearings;

(10) Establishment of dates for the submission and service of such written testimony and exhibits as may be appropriate in advance of the hearing;

(11) The order of presentation of the evidence and cross-examination of witnesses so that the hearing may proceed in the most expeditious and orderly manner possible; and

(12) All other matters which would aid in an expeditious disposition of the proceeding, including consent of the parties to the conduct of the entire proceedings off the record.

(f) Rulings by presiding officer. (1) The presiding officer at a prehearing conference, shall, irrespective of the consent of the parties, dispose of by ruling:

(i) Any of the procedural matters itemized in paragraph (e) of this section; and

(ii) Such other procedural matters on which the presiding officer is authorized to rule during the course of the hearing if ruling at this stage would expedite the proceeding.

(2) Either on the record at the conclusion of such prehearing conference, or by order issued shortly thereafter, the presiding officer shall state the agreements reached by the parties, the actions taken, and the rulings made by the presiding officer. Such rulings shall control the subsequent course of the proceedings unless modified during the hearing to prevent manifest injustice.

(a) In any case noticed for a proceeding to be determined on the record, the Commission or the presiding officer, if one has been appointed, may determine whether to hold a public hearing, or to hold a hearing by written submission of material only. A public hearing may be held if a hearing is requested by any party to the proceeding or if the Commission determines that a hearing is in the public interest. Generally, public hearings provide an opportunity for oral cross-examination of witnesses whereas hearings held by written submission of material only do not.

(b) Once established, requests to change the hearing format may be proposed by motion, or by the Commission's or presiding officer's own motion.

(c) Only representatives of the Commission, parties that have intervened in a proceeding, or persons intending to intervene prior to the deadline for notices of intervention may participate in a public hearing. However, public hearings are generally open to the public for observation. Public hearings may be closed to the public for good cause, or when confidential material is being presented.

(a) When issued. Upon consideration of the outcome of the prehearing conference, if held, and a determination of the need for a public hearing, the Commission, or the presiding officer if one has been appointed, shall issue a scheduling order. The scheduling order may be combined with any other order or ruling that the Commission or the presiding officer may issue. The scheduling order may be periodically modified as warranted.

(b) Content of scheduling order. The content of the scheduling order shall be tailored to the specifics of the matter before the Commission, including any requirement for a public hearing. The Commission or the presiding officer shall consider scheduling the following:

(1) A deadline for conclusion of discovery on proponent's direct case;

(2) A deadline to request oral cross-examination of proponent's witnesses;

(3) A deadline for designation of written cross-examination on proponent's direct case;

(4) The time and date for a public hearing on proponent's direct case, or the date and procedures for entering a proponent's direct case into evidence in a hearing by written submission of material only;

(5) A deadline for parties other than the proponent to file testimony in support of, or in rebuttal to, the proponent's direct case;

(6) A deadline for conclusion of discovery on testimony supporting or rebutting the proponent's direct case;

(7) A deadline to request oral cross-examination of other parties' witnesses;

(8) A deadline for designation of written cross-examination on other parties' testimony;

(9) The time and date for a public hearing on other parties' testimony, or the date and procedures for entering other parties' testimony in a hearing by written submission of material only;

(10) A deadline for the proponent to file surrebuttal testimony to other parties' direct cases;

(11) A deadline for conclusion of discovery on any proponent's surrebuttal rebuttal testimony;

(12) A deadline to request oral cross-examination of proponent's surrebuttal witnesses;

(13) A deadline for designation of written cross-examination on proponent's surrebuttal testimony;

(14) The time and date for a public hearing on a proponent's surrebuttal testimony, or the date and procedures for entering a proponent's surrebuttal testimony in a hearing by written submission of material only;

(15) A deadline for filing briefs;

(16) A deadline for filing reply briefs; and

(17) A deadline for requesting oral argument.

(c) Witness availability. Parties shall promptly file notice of potential witness unavailability to appear at any public hearing as soon as known. Witness unavailability will be considered when establishing the initial, or any subsequent, procedural schedules. Once the initial scheduling order is issued, but no later than ten calendar days prior to a scheduled hearing, parties may file notice of preferences for dates and times of witness appearance at any public hearing.

(d) Subsequent scheduling of public hearings. At the adjournment of any public hearing (including prehearing conferences), the Commission, or the presiding officer if appointed, shall announce when the hearing will reconvene. If an announcement is not made, the Commission or the presiding officer shall announce the time, date, and location of the subsequent hearing, or prehearing conference in writing by notice, order, or presiding officer ruling.

(a) Sections 3010.311 through 3010.313 allow discovery reasonably calculated to lead to admissible evidence during a proceeding noticed for hearing on the record. In general, discovery against a party will be scheduled to end prior to the receipt into evidence of that party's direct case. An exception to this procedure shall operate in all proceedings set for hearing when a party needs to obtain information (such as operating procedures or data) available only from the Postal Service. Such discovery requests are permissible only for the purpose of the development of rebuttal testimony and may be made up to 20 days prior to the filing date for final rebuttal testimony.

(b) The discovery procedures set forth in §§ 3010.311 through 3010.313 are not exclusive. Parties are encouraged to engage in informal discovery whenever possible to clarify exhibits and testimony. The results of these efforts may be introduced into the record by stipulation, by supplementary testimony or exhibit, by presenting selected written interrogatories and answers for adoption by a witness at the hearing, or by other appropriate means. In the interest of reducing motion practice, parties also are expected to use informal means to clarify questions and to identify portions of discovery requests considered overbroad or burdensome.

(c) If a party or an officer or agent of a party fails to obey an order of the Commission or the presiding officer to provide or permit discovery pursuant to §§ 3010.311 through 3010.313, the Commission or the presiding officer may make such orders in regard to the failure as are just, and among others, may direct that the matters regarding which the order was made or any other designated facts shall be taken to be established for the purposes of the proceeding in accordance with the claim of the parties obtaining the order, or prohibit the disobedient party from introducing designated matters in evidence, or strike the evidence, complaint or pleadings or parts thereof.

(a) Service and contents. In the interest of expedition and limited to information which appears reasonably calculated to lead to the discovery of admissible evidence, any party may propound to any other party in a proceeding written, sequentially numbered interrogatories, by witness, requesting non-privileged information relevant to the subject matter and reasonably calculated to lead to the discovery of admissible evidence in such proceeding, to be answered by the party served, who shall furnish such information as is available to the requesting party. A party through interrogatories may require any other party to identify each person whom the other party expects to call as a witness at the hearing and to state the subject matter on which the witness is expected to testify. The party propounding the interrogatories shall file them with the Commission and serve them on the answering party. Follow-up interrogatories to clarify or elaborate on the answer to an earlier discovery request may be filed after the initial discovery period ends. They must be filed within seven days of receipt of the answer to the previous interrogatory unless extraordinary circumstances are shown.

(b) Answers. Answers to discovery requests shall be prepared so that they can be incorporated as written cross-examination. Each answer shall begin on a separate page, identify the individual responding and the relevant testimony number, if any, the party who asked the question, and the number and text of the question. Each interrogatory shall be answered separately and fully in writing, unless it is objected to, in which event the reasons for objection shall be stated in the manner prescribed by paragraph (c) of this section. The party responding to the interrogatories shall file the answers with the Commission and serve them on the requesting party within 14 days of the filing of the interrogatories or within such other period as may be fixed by the Commission or presiding officer, but before the conclusion of the hearing.

(c) Objections. In the interest of expedition, the grounds for every objection shall be clearly and fully stated. If an objection is made to part of an interrogatory, the part shall be specified. A party claiming privilege shall identify the specific evidentiary privilege asserted and state the reasons for its applicability. A party claiming undue burden shall state with particularity the effort that would be required to answer the interrogatory, providing estimates of cost and work hours required, to the extent possible. An interrogatory otherwise proper is not necessarily objectionable because an answer would involve an opinion or contention that relates to fact or the application of law to fact, but the Commission or presiding officer may order that such an interrogatory need not be answered until a prehearing conference or other later time. Objections shall be filed with the Commission and served on the requesting party within ten days of the filing of the interrogatories. Any ground not stated in a timely objection is waived unless excused by the Commission or presiding officer for good cause shown.

(d) Motions to compel responses to discovery. Motions to compel a more responsive answer, or an answer to an interrogatory to which an objection was interposed, should be filed within 14 days of the answer or objection to the discovery request. The text of the discovery request, and any answer provided, should be provided as an attachment to the motion to compel. Parties who have objected to interrogatories which are the subject of a motion to compel shall have seven days to answer. Answers will be considered supplements to the arguments presented in the initial objection.

(e) Compelled answers. The Commission, or the presiding officer, upon motion of any party to the proceeding, may compel a more responsive answer, or an answer to an interrogatory to which an objection has been raised if the objection is overruled, or may compel an additional answer if the initial answer is found to be inadequate. Such compelled answers shall be filed with the Commission and served on the compelling party within seven days of the date of the order compelling an answer or within such other period as may be fixed by the Commission or presiding officer, but before the conclusion of the hearing.

(f) Supplemental answers. The individual or party who has answered interrogatories is under the duty to seasonably amend a prior answer if the individual or party obtains information upon the basis of which the individual or party knows that the answer was incorrect when made or is no longer true. Parties shall serve supplemental answers to update or to correct responses whenever necessary, up until the date the answer could have been accepted into evidence as written cross-examination. Parties filing supplemental answers shall indicate whether the answer merely supplements the previous answer to make it current or whether it is a complete replacement for the previous answer.

(g) Orders. The Commission or the presiding officer may order that any party or person shall answer on such terms and conditions as are just and may for good cause make any protective order, including an order limiting or conditioning interrogatories, as justice requires to protect a party or person from undue annoyance, embarrassment, oppression, or expense.

(a) Service and contents. In the interest of expedition and limited to information which appears reasonably calculated to lead to the discovery of admissible evidence, any party may serve on any other party to the proceeding a request to produce and permit the party making the request, or someone acting on behalf of the requesting party or the requesting party's agent to inspect and copy any designated documents or things that constitute or contain matters, not privileged, that are relevant to the subject matter involved in the proceeding or reasonably calculated to lead to the discovery of admissible evidence and that are in the custody or control of the party to whom the request is addressed. The request shall set forth the items to be inspected either by individual item or category, and describe each item and category with reasonable particularity, and shall specify a reasonable time, place and manner of making inspection. The party requesting the production of documents or things shall file its request with the Commission and serve the request on the responding party.

(b) Answers. The party responding to the request shall file an answer with the Commission and serve the answer on the requesting party within 14 days after the request is filed, or within such other period as may be fixed by the Commission or presiding officer. The answer shall state, with respect to each item or category, that inspection will be permitted as requested unless the request is objected to pursuant to paragraph (c) of this section. The responding party may produce copies of documents or of electronically stored information in lieu of permitting inspection. Production must be completed no later than the time for inspection specified in the request unless good cause is shown.

(c) Objections. In the interest of expedition, the grounds for objection shall be clearly and fully stated. If an objection is made to part of an item or category, the part shall be specified. Any objection must state whether any responsive materials are being withheld on the basis of that objection. A party claiming privilege shall identify the specific evidentiary privilege asserted and state with particularity the reasons for its applicability. A party claiming undue burden shall state with particularity the effort that would be required to answer the request, providing estimates of cost and work hours required, to the extent possible. Objections shall be filed with the Commission and served on the requesting party within ten days of the request for production. The responding party may state an objection to a request to produce electronically stored information. If it objects to the form of the documents or things requested (or if no form was specified in the request), the responding party must state the form or forms it intends to use to produce the requested information.

(d) Motions to compel requests for production of documents or things for purposes of discovery. Motions to compel shall be filed within 14 days of the answer or objection to the discovery request. The text of the discovery request, and any answer provided, should be provided as an attachment to the motion to compel. Parties who have objected to requests for production of documents or things which are the subject of a motion to compel shall have seven days to answer. Answers will be considered supplements to the arguments presented in the initial objection.

(e) Compelled answers. Upon motion of any party to the proceeding to compel a response to discovery, as provided in paragraph (d) of this section, the Commission or the presiding officer may compel production of documents or things to which an objection is overruled. Such compelled documents or things shall be made available to the party making the motion within seven days of the date of the order compelling production or within such other period as may be fixed by the Commission or presiding officer, but before the conclusion of the hearing.

(f) Orders and rulings. The Commission or the presiding officer may direct any party or person to respond to a request for inspection on such terms and conditions as are just and may for good cause impose any protective conditions, including limitations or preconditions for inspections, as justice requires to protect a party or person from undue annoyance, embarrassment, oppression, or expense.

(a) Service and content. In the interest of expedition, any party may serve upon any other party a written request for the admission, for purposes of the pending proceeding only, of any relevant, unprivileged facts, including the genuineness of any documents or exhibits to be presented in the hearing. Each requested admission shall be set forth separately and shall be deemed admitted unless within 14 days after the request is filed (or such other period as may be fixed by the Commission or presiding officer) the party to whom the request is directed files a written answer denying the requested admission pursuant to paragraph (c) of this section or objecting pursuant to paragraph (d) of this section. The party requesting an admission shall file its request with the Commission and serve the request on the responding party.

(b) Answers. Answers that fail to admit a matter as requested shall specifically deny the matter or set forth in detail the reasons why the answering party cannot truthfully admit or deny the matter. A denial shall fairly meet the substance of the requested admission. When a party qualifies an answer or denies only a part of the admission requested, the party shall specify so much of the requested admission as is true and qualify or deny the remainder. A failure to admit or deny for lack of information or knowledge shall not be made unless the responding party states that it has made a reasonable inquiry and that information known or readily obtainable by the party is insufficient to enable the party to admit or deny. A party who answers a request for admission shall file its answer with the Commission and serve the answer on the requesting party.

(c) Objections. If an objection is made, the grounds for such objection shall be clearly and fully stated. If an objection is made to part of an item, the part to which an objection is made shall be specified. A party claiming privilege shall identify the specific evidentiary privilege asserted and state the reasons for its applicability. A party claiming undue burden shall state with particularity the effort that would be required to answer the request, providing estimates of cost and work hours required to the extent possible. Objections shall be filed with the Commission and served on the requesting party, within ten days of the request for admissions.

(d) Motions to compel responses to requests for admissions. The party who has requested an admission may move to determine the sufficiency of the answers or objections. Motions to compel a more responsive answer, or an answer to a request to which an objection was interposed, shall be filed within 14 days of the answer or objection to the request for admissions. The text of the request for admissions, and any answer provided, should be provided as an attachment to the motion to compel. Parties who have objected to requests for admissions which are the subject of a motion to compel shall have seven days to file a response. Responses will be considered supplements to the arguments presented in the initial objection.

(e) Compelled answers. The Commission or the presiding officer may compel answers to a request for admissions to which an objection has been raised if the objection is overruled. Such compelled answers shall be filed with the Commission and served on the requesting party within seven days of the date of the order compelling production or within such other period as may be fixed by the Commission or the presiding officer, but before the conclusion of the hearing. If the Commission or presiding officer determines that an answer does not comply with the requirements of this rule, it may order either that the matter is admitted or that an amended answer be filed.

Any party to a proceeding may submit offers of settlement or proposals of adjustment at any time and may request a conference between the parties to consider such offers or proposals. The Commission or the presiding officer shall afford the parties appropriate opportunity prior to or during the hearing for conferences for the purpose of considering such offers or proposals as time, the nature of the proceeding, and the public interest permit. Unaccepted offers of settlement or adjustment and proposed stipulations not agreed to shall be privileged and shall not be admissible in evidence against any party claiming such privilege.

(a) How convened. (1) Hearings shall be convened by the issuance of a notice, order, or presiding officer's ruling that is published in the Federal Register. Only the first session of a public hearing need be noticed and published in the Federal Register. All subsequent sessions within a docket are to be considered part of the same hearing. If there is a prehearing conference, the prehearing conference is to be considered the first hearing session in that docket.

(2) At the adjournment of each hearing session, the presiding officer responsible for the conduct of that hearing session shall announce if and when the hearing will reconvene. If an announcement is not made at the adjournment of the hearing session, the Commission or presiding officer shall announce the time, date, and location of any subsequent hearing, or prehearing conference, in writing by notice, order, or presiding officer ruling.

(b) Who presides. The presiding officer, if designated, shall preside over a public hearing. If a presiding officer has not been designated or is otherwise unavailable for a hearing, then the ranking Commissioner in attendance shall be considered the presiding officer for that hearing. The presiding officer shall open and close each session of the hearing, and shall be responsible for controlling the conduct of the hearing.

(c) Entering of appearances. The presiding officer before whom the hearing is held will cause to be entered on the record all appearances together with a notation showing on whose behalf each such appearance has been made.

(d) Witnesses. All witnesses are expected to be available for public hearings. Unless otherwise ordered by the presiding officer, a witness need only attend a hearing on those days scheduled for entering that witness's testimony. Subject to the discretion and prior approval of the presiding officer, a witness may be excused from appearing at a hearing and may have the witness's written testimony and cross-examination entered into evidence by counsel.

(e) Order of presentations. (1) The proponent of a matter before the Commission shall present the proponent's direct case first. In matters initiated by the Postal Service, the Postal Service shall be considered the proponent. In complaint proceedings under section 3662 of the Act, the complainant shall be considered the proponent. The proponent also shall be provided an opportunity to respond to any rebuttal to the proponent's direct case. In all other instances, the Commission or the presiding officer shall determine the order of presentation.

(2) The order of presentations by parties other than the proponent shall be determined by the Commission or the presiding officer.

(3) The Commission or presiding officer shall announce the order of presentation of parties and individual witnesses prior to hearing sessions and shall issue such other procedural orders as may be necessary to assure the orderly and expeditious conclusion of the hearing. Parties may present their preferences for order of appearance to the Commission or the presiding officer orally at a hearing or by filing a notice prior to the scheduled hearing date. Parties who disagree with a proposed order of appearances may move for a revised order of appearances either orally at a hearing or by filing a written motion pursuant to § 3010.160.

(f) Swearing in of witnesses. (1) Witnesses attending a hearing whose testimony is to be taken shall be sworn, or shall affirm, before their testimony shall be deemed evidence in the proceeding or any questions are put to them. The witness shall be sworn by means of the following (or an equivalent): “Please raise your right hand. Do you solemnly swear (or affirm), that the testimony that you are about to give is the truth, the whole truth, and nothing but the truth? Please state your full name.”

(2) The oath shall be given upon the first appearance of the witness providing testimony. Upon subsequent appearances, the witness is to be reminded by the presiding officer that the witness remains under oath for the duration of the proceeding.

(3) Witnesses not attending a hearing whose testimony is entered by counsel during a hearing shall attach a signed declaration that the testimony being submitted is that of the witness. A declaration shall be included with each piece of written testimony, and each set of written cross-examination. The declaration shall state the following (or an equivalent): “Declaration of [witness name]. I, [witness name], hereby declare under penalty of perjury that: The [testimony, designated responses to written cross-examination] filed under my name were prepared by me or under my direction; and were I to [provide oral testimony, respond orally to the questions appearing in the interrogatories], my answers would be the same.”

(4) Hearings that are conducted by the written submission of testimony only shall also attach written declarations to testimony and cross-examination as described above.

(g) Presentation of the evidence—(1) Presentations by parties. Each party shall have the right to present evidence, cross-examine witnesses (limited to testimony adverse to the party conducting the cross-examination), and to present objections, motions, and arguments. The case-in-chief of parties other than the proponent shall be in writing and shall include the party's direct case and rebuttal, if any, to the initial proponent's case-in-chief. A party's presentation may be accompanied by a trial brief or legal memoranda. Legal memoranda on matters at issue are generally welcome at any stage of the proceeding. Parties will be given an opportunity to rebut presentations of other parties, including an opportunity for the initial proponent to present surrebuttal evidence. New affirmative matter (not in reply to another party's direct case) should not be included in rebuttal testimony or exhibits. When objections to the admission or exclusion of evidence before the Commission or the presiding officer are made, the grounds relied upon shall be stated. Formal exceptions to rulings are unnecessary.

(2) Written testimony. (i) Written testimony shall be offered in evidence by motion. The motion shall be made orally during a hearing, or in writing when the hearing is conducted by the written submission of testimony only. When a party moves to enter testimony into the record, three hard copies of the document shall simultaneously be submitted to the Commission for the record. The copies are to be printed single-sided, and not stapled, hole-punched, or bound, but may be fastened together by paper or binder clip, or equivalent.

(ii) Witnesses shall be provided an opportunity to verify that the written testimony they are sponsoring is their testimony and that it would be the same if given orally. The witness, or counsel, shall state the original filing date of the testimony and identify all subsequent filings that amended the original testimony. If there are any final corrections to the testimony, the corrections may be noted on the hard copies submitted to the Commission. However, the witness shall be required to file errata to the testimony within seven days of the hearing, making corrections only to the extent as identified during the hearing. Any other changes shall be requested separately by motion to amend the record.

(iii) Parties shall be provided an opportunity to object to all or part of a witness's written testimony prior to entering that testimony into the record. Objections that have not previously been made in writing at least 14 days prior to the hearing date shall be granted only under extraordinary circumstances.

(iv) After resolution of all objections, the presiding officer shall order the testimony entered into the record as evidence. Unless otherwise ordered by the presiding officer, the written testimony shall not be copied into the hearing transcript.

(3) Library references. (i) Library references sponsored by a witness and associated with the witness's written testimony or written cross-examination may be offered in evidence by motion. The motion shall be made orally during a public hearing, or in writing for a hearing that is conducted by the written submission of testimony only.

(ii) Witnesses shall be provided an opportunity to verify that the library reference is their library reference and to affirm that they are in fact sponsoring the library reference. If a witness inadvertently fails to verify and affirm that the witness is sponsoring a library reference that is cited in written testimony or in response to written cross-examination, it will be presumed that the library reference is to be included in the record to the extent specified in the notice of the filing of the library reference.

(iii) Parties shall be provided an opportunity to object to all or any part of the library reference being entered into the record. Objections that have not been made in writing at least 14 days prior to the hearing date shall be granted only under extraordinary circumstances.

(iv) After resolution of all objections, the presiding officer shall order the library reference be entered into the record as evidence. Unless ordered by the presiding officer, library references shall not be copied into the hearing transcript.

(4) Written cross-examination. (i) Written cross-examination will be utilized as a substitute for oral cross-examination whenever possible, particularly to introduce factual or statistical evidence. Written cross-examination may be offered in evidence by motion. The motion shall be made orally during a public hearing, or in writing for a hearing that is conducted by the written submission of testimony only. Written cross-examination proposed by parties other than the party associated with the witness shall be considered first, followed by that of the party of the witness.

(ii) Designations of written cross-examination should be filed with the Commission and served on the answering party no later than three working days before the scheduled appearance of a witness. Designations shall identify every item to be offered as evidence, listing the party who initially posed the discovery request, the witness and/or party to whom the question was addressed (if different from the witness answering), the number of the request and, if more than one answer is provided, the dates of all answers to be included in the record. (For example, “PR-T1-17 to USPS witness Jones, answered by USPS witness Smith (March 1, 1997) as updated (March 21, 1997)).” When a party designates written cross-examination, three hard copies of the documents to be included shall simultaneously be submitted to the Secretary. The documents are to be printed single-sided, and not stapled, hole-punched, or bound, but may be fastened together by paper or binder clip, or equivalent. The Secretary shall prepare for the record a packet containing all materials designated for written cross-examination in a format that facilitates review by the witness and counsel.

(iii) A witness shall be provided an opportunity to verify that the written cross-examination is that of the witness and to assert that if the written cross-examination were being provided orally at the hearing it would be that of the witness. If there are any final corrections to the written cross-examination, the corrections may be noted on the hard copies before submission to the Commission.

(iv) Parties shall be provided an opportunity to object to all or any part of the written cross-examination prior to entering the testimony into the record.

(v) After resolution of all objections, the presiding officer shall order the written cross-examination entered into the record as evidence. The presiding office shall direct that the written cross-examination be copied into the hearing transcript.

(5) Oral cross-examination. (i) Oral cross-examination will be permitted for clarifying written cross-examination and for testing assumptions, conclusions, or other opinion evidence.

(ii) Notices of intent to conduct oral cross-examination should be filed three or more working days before the announced appearance of the witness and should include specific references to the subject matter to be examined and page references to the relevant direct testimony and exhibits. If no notices are filed, and the Commission or presiding officer has no other reason for the witness to appear, the Commission or the presiding officer, in their discretion, may excuse the witness from appearing at the hearing and direct that the witness's testimony be entered by counsel.

(iii) A party intending to use complex numerical hypotheticals, or to question using intricate or extensive cross-references, shall provide adequately documented cross-examination exhibits for the record. Copies of these exhibits should be filed at least two full business days before the scheduled appearance of the witness. They may be filed online or delivered in hardcopy form to counsel for the witness, at the discretion of the party. When presented, examination exhibits are not to be considered record evidence. They are to be transcribed into the record for reference only. If adopted by the witness, the examination exhibit may be offered in evidence by motion.

(iv) At the conclusion of oral cross-examination, the witness shall be given an opportunity to consult with counsel. Counsel shall then be provided an opportunity to examine the witness for the purpose of clarifying statements previously made during oral cross-examination.

(h) Institutional testimony. (1) This paragraph (h) is applicable to testimony offered in evidence that is not sponsored by an individual witness. This typically occurs when discovery questions are answered by the institution, and not by an individual witness.

(2) When institutional responses are offered in evidence by any party, the responding party shall make available at the hearing an officer of the institution that has the authority to attest to the authenticity and truthfulness of the responses, and that has the knowledge to be subject to oral cross-examination in regard to the responses. Section 3010.321 applies as if the officer of the institution were an individual witness.

(i) Limitations on presentation of the evidence. The taking of evidence shall proceed with all reasonable diligence and dispatch, and to that end, the Commission or the presiding officer may limit appropriately the number of witnesses to be heard upon any issue, the examination by any party to specific issues, and the cross-examination of a witness to that required for a full and true disclosure of the facts necessary for the disposition of the proceeding and to avoid irrelevant, immaterial, or unduly repetitious testimony.

(j) Motions during hearing. After a hearing has commenced, a request may be made by motion to the presiding officer for any procedural ruling or relief desired. Such motions shall specify the ruling or relief sought, and state the grounds therefor and statutory or other supporting authority. Motions made during hearings may be stated orally upon the record, except that the presiding officer may require that such motions be reduced to writing and filed separately. Any party shall have the opportunity to answer or object to such motions at the time and in the manner directed by the presiding officer.

(k) Rulings on motions. The presiding officer is authorized to rule upon any such motion not formally acted upon by the Commission prior to the commencement of a prehearing conference or hearing where immediate ruling is essential in order to proceed with the prehearing conference or hearing, and upon any motion to the presiding officer filed or made after the commencement thereof, except that no motion made to the presiding officer, a ruling upon which would involve or constitute a final determination of the proceeding, shall be ruled upon affirmatively by the presiding officer except as a part of a presiding officer's intermediate decision. This section shall not preclude a presiding officer, within the presiding officer's discretion, from referring any motion made in hearing to the Commission for ultimate determination.

(l) Transcript corrections. Corrections to the transcript of a hearing should not be requested except to correct a material substantive error in the transcription made at the hearing. Any request to correct a transcript shall be by motion filed no later than seven days after the transcript, or notice of the availability of a confidential transcript, is posted to the Commission's website. Corrections or changes to actual testimony shall not be allowed.

(a) Form and admissibility. In all hearings, relevant and material evidence which is not unduly repetitious or cumulative shall be admissible. Witnesses whose testimony is to be taken shall be sworn, or shall affirm, before their testimony shall be deemed evidence in the proceeding or any questions are put to them.

(b) Documentary material—(1) General. Documents and detailed data and information shall be presented as exhibits. Exhibits should be self-explanatory. They should contain appropriate footnotes or narrative explaining the source of each item of information used and the methods employed in statistical compilations. The principal title of each exhibit should state what it contains or represents. The title may also contain a statement of the purpose for which the exhibit is offered; however, this statement will not be considered part of the evidentiary record. Where one part of a multi-part exhibit is based on another part or on another exhibit, appropriate cross-references should be made. Relevant exposition should be included in the exhibits or provided in accompanying testimony. Testimony, exhibits and supporting workpapers prepared for Commission proceedings that are premised on data or conclusions developed in a library reference shall provide the location of that information within the library reference with sufficient specificity to permit ready reference, such as the page and line, or the file and the worksheet or spreadsheet page or cell. Where relevant and material matter offered in evidence is embraced in a document containing other matter not material or relevant or not intended to be put in evidence, the party offering the same shall plainly designate the matter offered excluding the immaterial or irrelevant parts. If other matter in such document is in such bulk or extent as would unnecessarily encumber the record, it may be marked for identification, and, if properly authenticated, the relevant and material parts may be read into the record, or, if the Commission or presiding officer so directs, a true copy of such matter in proper form shall be received in evidence as an exhibit. Copies of documents shall be delivered by the party offering the same to the other parties or their attorneys appearing at the hearing, who shall be afforded an opportunity to examine the entire document and to offer in evidence in like manner other material and relevant portions thereof.

(2) Status of library references. Designation of material as a library reference and acceptance in the Commission's docket section do not confer evidentiary status. The evidentiary status of the material is governed by § 3010.321(g)(3).

(c) Commission's files. Except as otherwise provided in paragraph (e) of this section, any matter contained in a report or other document on file with the Commission may be offered in evidence by specifying the report, document, or other file containing the matter so offered and the report or other document need not be produced or marked for identification.

(d) Public document items. Whenever there is offered in evidence (in whole or in part) a public document, such as an official report, decision, opinion or published scientific or economic statistical data issued by any of the Executive Departments (or their subdivisions), legislative agencies or committees, or administrative agencies of the Federal Government (including Government-owned corporations) and such document (or part thereof) has been shown by the offeror thereof to be reasonably available to the public, such document need not be produced or physically marked for identification, but may be offered in evidence as a public document item by clearly identifying the document and the relevant parts thereof.

(e) Designation of evidence from other Commission dockets. (1) Parties may request that evidence received in other Commission proceedings be entered into the record of the current proceeding. These requests shall be made by motion, shall explain the purpose of the designation, and shall identify material by page and line or paragraph number.

(2) In proceedings to consider the appeal of a Postal Service determination to close or consolidate a post office conducted pursuant to part 3021 of this chapter, these requests must be made at least six days before the date for filing the party's direct case. Oppositions to motions for designations and/or requests for counter-designations shall be filed within three days. Oppositions to requests for counter-designations are due within two days.

(3) In all other proceedings subject to this section, these requests must, in the absence of extraordinary circumstances, be made at least 28 days before the date for filing the party's direct case. Oppositions to motions for designations and/or requests for counter-designations shall be filed within 14 days. Oppositions to requests for counter-designations are due within seven days.

(4) In all proceedings subject to this section, the moving party must submit two copies of the identified material to the Secretary at the time requests for designations and counter-designations are made.

(f) Form of prepared testimony and exhibits. Unless the presiding officer otherwise directs, the direct testimony of witnesses shall be reduced to writing and offered either as such or as an exhibit. All prepared testimony and exhibits of a documentary character shall, so far as practicable, conform to the requirements of § 3010.124(a) and (b).

(g) Copies to parties. Except as otherwise provided in these rules, copies of exhibits shall be furnished to the presiding officer and to the parties or counsel during a hearing, unless the presiding officer otherwise directs.

(h) Reception and ruling. The presiding officer shall rule on the admissibility of evidence and otherwise control the reception of evidence so as to confine it to the issues in the proceeding.

(i) Offers of proof. Any offer of proof made in connection with any ruling of the presiding officer rejecting or excluding proffered oral testimony shall consist of a statement of the substance of the evidence which counsel contends would be adduced by such testimony; and if the excluded evidence consists of evidence in documentary or written form, or of reference to documents or records, a copy of such evidence shall be marked for identification and shall constitute the offer of proof.

(j) Official notice of facts. Official notice may be taken of such matters as might be judicially noticed by the courts of the United States or of any other matter peculiarly within the knowledge of the Commission as an expert body. Any party shall, on timely request, be afforded an opportunity to show the contrary.

(a) Statistical studies. All statistical studies offered in evidence in hearing proceedings or relied upon as support for other evidence shall include a comprehensive description of the assumptions made, the study plan utilized, the procedures undertaken, and references from the academic literature supporting the procedures undertaken. Machine-readable data files, program files, workbooks, and all other necessary materials to enable independent replication of the results or program output if requested by the Commission or parties shall be provided in the form of a compact disk or other media or method approved in advance by the Secretary. Where a computer analysis is employed to obtain the result of a statistical study, all of the submissions required by paragraph (b) of this section shall be furnished, upon request. In addition, for each of the following types of statistical studies, the following information should be provided:

(1) Market research. The following information shall be provided:

(i) A clear and detailed description of the sample, observational, and data preparation designs, including definitions of the target population, sampling frame, units of analysis, questionnaires or data collection instruments, survey variables, and the possible values;

(4) Econometric studies. The following information shall be provided:

(i) A presentation of the economic theory and assumptions underlying the study;

(ii) A complete description of the econometric model(s) and the reasons for each major assumption and specification;

(iii) The definition of the variables selected and the justification for their selection;

(iv) For any alternative model whose computed econometric results influenced the choice of the preferred model, a statement of the reasons for rejecting that alternative, an identification of any differences between that alternative and the preferred model with respect to variable definitions, equation forms, data, or estimation methods, and, upon request, the computed econometric results for that alternative;

(v) A reference to a detailed description in a text, manual, or technical journal for every econometric technique used in the estimation process and the reasons for selecting the technique, or, in the alternative, a description and analysis of the technique that is sufficient for a technical evaluation;

(vi) Summary descriptions and source citations for all input data and, upon request, a complete listing of the data. Complete descriptions of any alterations, adjustments, or transformations made to the data as received from the original sources, and the reasons for making the alterations, adjustments, or transformations;

(vii) A complete report of the econometric results including, where applicable coefficient estimates, standard errors and t-values, goodness-of-fit statistics, other appropriate test statistics, the variance/covariance matrix of the estimates, and computed residuals for results computed from samples composed of fewer than 250 observations, and, upon request, other computed residuals; and

(viii) Descriptions of all statistical tests of hypotheses and the results of such tests.

(5) All other studies involving statistical methodology. The following information shall be provided:

(i) The formula used for statistical estimates;

(ii) The standard errors of each component estimated;

(iii) Test statistics and the description of statistical tests and all related computations, and final results; and

(iv) Summary descriptions of input data, and upon request the actual input data shall be made available at the offices of the Commission.

(b) Computer analyses. (1) In the case of computer studies or analyses which are being offered in evidence, or relied upon as support for other evidence, a foundation for the reception of such materials must be laid by furnishing a general description of the program that includes the objectives of the program, the processing tasks performed, the methods and procedures employed, and a listing of the input and output data and source codes (or a showing pursuant to paragraph (b)(3) of this section as to why such codes cannot be so furnished) and such description shall be furnished in all cases. For the purpose of completing such foundation, the following additional items shall be deemed presumptively necessary and shall be furnished upon request of a party, the Commission, or the presiding officer, unless the presumption is overcome by an affirmative showing. The following information shall be provided:

(i) For all input data, designations of all sources of such data, and explanations of any modifications to such data made for use in the program;

(ii) Definitions of all input and output variables or sets of variables;

(vi) If the requested program is user interactive, a representative sample run, together with any explanation necessary to illustrate the response sequence;

(vii) An expert on the design and operation of the program shall be provided at a technical conference to respond to any oral or written questions concerning information that is reasonably necessary to enable independent replication of the program output; and

(viii) Computer simulation models offered in evidence or relied upon as support for other evidence, shall be bound by all applicable provisions of this paragraph (b) and the separate requirements of paragraph (a) of this section, to the extent that portions of the simulation model utilize or rely upon such studies. Information that compares the simulation model output results to the actual phenomena being modelled, using data other than those from which the model was developed, shall be separately identified and submitted as evidence supporting the test and validation of the simulation model. Separate statements concerning the model limitations, including limiting model design assumptions and range of data input utilized in model design, shall be provided. Where test and validation of the entire simulation model are not possible, test and validation information shall be provided for disaggregate portions of the model. If disaggregate testing and validation are not possible, separate statements to that effect and statements regarding operational experts' review of model validity shall be provided.

(2) Upon timely and otherwise proper request of a party, or sua sponte, the Commission or the presiding officer may rule that matters other than those listed in paragraphs (b)(1)(i) through (viii) of this section are necessary to establish the foundation for reception of the evidence concerned and must be furnished.

(3) When the requestor is other than the Commission or the presiding officer, the cost of producing the material required in paragraphs (b)(1)(iv), (vi), and (vii) of this section, shall be borne by the requesting party unless otherwise ordered, for good cause shown by the requestor. When the Commission or the presiding officer is the requestor, it may assume or equitably allocate such costs for good cause shown by the requester.

(4) If the recipient of a request for materials pursuant to this paragraph (b) asserts that compliance with the request would conflict with patent, copyright, trade secret or contract rights applicable to the requested material, the recipient shall immediately notify the requestor and the presiding officer. If valid, the presiding officer shall devise means of accommodating such rights. Such means may include protective orders, including access under protective conditions to the computer facilities of the recipient of a request, making material available for inspection, compensation, or other procedures, according to the nature of the right affected by compliance with this paragraph (b). If the presiding officer determines that compensation is necessary to accommodate the affected right, the cost of compensation shall be borne in the same manner that paragraph (b)(3) of this section prescribes for bearing the costs referenced there. If such right cannot be accommodated by reasonable compensation, or by protective orders or other procedures, and, as a result, materials required by this paragraph (b) cannot be provided, the presiding officer shall determine, in the presiding officer's discretion, whether evidence that relies upon the materials not provided shall be admissible or afforded limited weight.

(c) Other studies and analyses. In the case of all studies and analyses offered in evidence in hearing proceedings or relied upon as support for other evidence, other than the kinds described in paragraphs (a) and (b) of this section, there shall be a clear statement of the study plan, all relevant assumptions and a description of the techniques of data collection, estimation and/or testing. In addition, there shall be a clear statement of the facts and judgments upon which conclusions are based, together with an indication of the alternative courses of action considered and the steps taken to ensure the validity, accuracy, and reliability of the evidence. Tabulations of input data, workbooks, and all other materials necessary to replicate results shall be made available upon request at the offices of the Commission.

(d) Expedition. The party who offers studies or analyses in evidence shall expedite responses to requests made pursuant to this section for data or other information. Responses shall be served on the requesting party, and notice thereof filed with the Secretary in accordance with the provisions of § 3010.127 no later than 3 days after a request is made under § 3010.322(e)(2) or no later than 14 days after a request is made under § 3010.322(e)(3).

(a) Definition. Except as hereinafter provided, documents and testimony made subject to in camera orders are not made a part of the public record, but are kept confidential, and only authorized parties, their counsel, authorized Commission personnel, and court personnel concerned with judicial review shall have access thereto. The right of the presiding officer, the Commission, and reviewing courts to disclose in camera data to the extent necessary for the proper disposition of the proceeding is specifically reserved.

(b) In camera treatment of documents and testimony. (1) Presiding officers shall have authority, but only in those unusual and exceptional circumstances when good cause is found on the record, to order documents or oral testimony offered in evidence whether admitted or rejected, to be placed in camera. The order shall specify the date on which in camera treatment expires and shall include:

(i) A description of the documents and testimony;

(ii) A full statement of the reasons for granting in camera treatment; and

(iii) A full statement of the reasons for the date on which in camera treatment expires.

(2) Any party desiring, for the preparation and presentation of the case, to disclose in camera documents or testimony to experts, consultants, prospective witnesses, or witnesses, shall make application to the presiding officer setting forth the justification therefor. The presiding officer, in granting such application for good cause found, shall enter an order protecting the rights of the affected parties and preventing unnecessary disclosure of information. In camera documents and the transcript of testimony subject to an in camera order shall be segregated from the public record and filed in a sealed envelope, bearing the title and docket number of the proceeding, the notation “In Camera Record under § 3010.323,” and the date on which in camera treatment expires.

(c) Release of in camera information. In camera documents and testimony shall constitute a part of the confidential records of the Commission. However, the Commission, on its own motion or pursuant to a request, may make in camera documents and testimony available for inspection, copying, or use by any other governmental agency. The Commission shall, in such circumstances, give reasonable notice of the impending disclosure to the affected party. However, such notice may be waived in extraordinary circumstances for good cause.

(d) Briefing of in camera information. In the submittal of proposed findings, briefs, or other papers, counsel for all parties shall make a good faith attempt to refrain from disclosing the specific details of in camera documents and testimony. This shall not preclude references in such proposed findings, briefs, or other papers to such documents or testimony including generalized statements based on their contents. To the extent that counsel consider it necessary to include specific details of in camera data in their presentations, such data shall be incorporated in separate proposed findings, briefs, or other papers marked “confidential,” which shall be placed in camera and become a part of the in camera record.

(a) When permissible. The testimony of a witness may be taken by deposition when authorized by the Commission or the presiding officer on application of any party before the hearing is closed. An authorization to take the deposition of a witness will be issued only if:

(1) The person whose deposition is to be taken would be unavailable at the hearing;

(2) The deposition is deemed necessary to perpetuate the testimony of the witness; or

(3) The taking of the deposition is necessary to prevent undue and excessive expense to a party and will not result in undue delay or an undue burden to other parties.

(b) Application. An application for authorization to take testimony by deposition shall be filed with the Commission or the presiding officer and shall state:

(1) The name, identification, and post office address of the witness;

(2) The subject matter of the testimony.

(3) The time and place of taking the deposition;

(4) The name, identification, and post office address of the officer before whom the deposition is to be taken; and

(5) The reasons why the testimony of such witness should be taken by deposition.

(c) Authorization. If the application so warrants, the Commission or the presiding officer will issue and serve or cause to be served on the parties within a reasonable time in advance of the time fixed for taking testimony, an authorization for the taking of such testimony by deposition. Such authorization shall name the witness, the time, place, and officer before whom the deposition shall be taken, and shall specify the number of copies of the deposition to be submitted to the Commission. The authorization may include such terms and conditions as the Commission or the presiding officer deems fair and reasonable.

(d) Qualifications of officer before whom taken. Such deposition may be taken before a presiding officer or other authorized representative of the Commission, or any officer, not being counsel or attorney for any party or having an interest in the proceeding, authorized to administer oaths by the laws of the United States or of the place where the deposition is to be taken.

(e) Oath and reduction to writing. The officer before whom the deposition is to be taken shall put the witness on oath or affirmation and shall personally, or by someone acting under the officer's direction and in the officer's presence, record the examination of the witness. The examination shall be transcribed in the form specified in § 3010.124(a), signed by the witness, and certified in the usual form by the officer. The original of the deposition, together with the number of copies required by the authorization to be made by such officer, shall be forwarded by the officer to the Secretary by personal delivery or registered mail. Upon receipt, the Secretary shall hold the original for use in the hearing upon request by any party and shall make copies available for public inspection.

(f) Scope and conduct of examination. Unless otherwise directed in the authorization, the witness may be questioned regarding any matter which is relevant to the issues involved in the proceeding. Parties shall have the right for cross-examination and objection. In lieu of participation in the oral examination, parties may transmit written interrogatories to the officer who shall propound them to the witness.

(g) Objections. The officer before whom the deposition is taken shall not have the power to rule upon procedural matters or the competency, materiality, or relevancy of questions. Procedural objections or objections to questions of evidence shall be stated briefly and recorded in the deposition without argument. Objections not stated before the officer shall be deemed waived.

(h) When a part of the record. No portion of a deposition shall constitute a part of the record in the proceeding unless received in evidence by the presiding officer. If only a portion of the deposition is offered in evidence by a party, any other party may require the party to introduce all of it which is relevant to the part introduced, and any party may offer in evidence any other portions.

(i) Fees. Witnesses whose depositions are taken and the officer taking the same shall be entitled to the same fees as are paid for like services in the District Courts of the United States to be paid directly by the party or parties on whose application the deposition was taken.

(a) When filed. At the close of the taking of testimony in any proceeding, the Commission or the presiding officer shall fix the time for the filing and service of briefs, giving due regard to the timely issuance of the decision. In addition, subject to such consideration, due regard shall be given to the nature of the proceeding, the complexity and importance of the issues involved, and the magnitude of the record. In cases subject to a limitation on the time available to the Commission for decision, the Commission may direct each party to file its brief simultaneously with the filing of briefs by other parties. In cases where, because of the nature of the issues and the record or the limited number of parties involved, the filing of initial and reply briefs, or the filing of initial, answering, and reply briefs, will not unduly delay the conclusion of the proceeding and will aid in the proper disposition of the proceeding, the parties may be directed to file more than one brief and at different times rather than a single brief filed simultaneously with briefs filed by other parties. The Commission or presiding officer may also order the filing of briefs during the course of the proceeding.

(b) Contents. Each brief filed with the Commission shall be as concise as possible, within any page limitation specified by the Commission or the presiding officer, and shall include the following in the order indicated:

(1) A subject index with page references, and a list of all cases and authorities relied upon, arranged alphabetically, with references to the pages where the citation appears;

(2) A concise statement of the case from the viewpoint of the filing party;

(3) A clear, concise, and definitive statement of the position of the filing party as to the matter before the Commission and the decision to be issued;

(4) A discussion of the evidence, reasons, and authorities relied upon with exact references to the record and the authorities; and

(5) Proposed findings and conclusions with appropriate references to the record or the prior discussion of the evidence and authorities relied upon.

(c) Incorporation by references. Briefs before the Commission or a presiding officer shall be completely self-contained and shall not incorporate by reference any portion of any other brief, pleading, or document.

(d) Excerpts from the record. Testimony and exhibits shall not be quoted or included in briefs except for short excerpts pertinent to the argument presented.

(e) Filing and service. Briefs shall be filed with the Commission and served on all parties as required pursuant to subpart B of this part.

The Commission or the presiding officer may direct the filing of proposed findings and conclusions with a brief statement of the supporting reasons for each proposed finding and conclusion.

In any case in which the presiding officer is to issue an intermediate decision, such officer may permit the presentation of oral argument when, in the presiding officer's opinion, time permits, and the nature of the proceedings, the complexity or importance of the issues of fact or law involved, and the public interest warrants hearing such argument. The presiding officer shall determine the time and place for oral argument, and may specify the issue or issues on which oral argument is to be presented, the order in which the presentations shall be made, and the amount of time allowed each party. A request for oral argument before the issuance of an intermediate decision shall be made during the course of the hearing on the record.

(a) When ordered. In any proceeding before the Commission for decision, the Commission, upon the request of any party or on its own initiative, may order oral argument when, in the Commission's discretion, time permits, and the nature of the proceedings, the complexity or importance of the issues of fact or law involved, and public interest warrants such argument.

(b) How requested. Any party in a proceeding before the Commission for decision may request oral argument before the Commission by filing a timely motion. In a proceeding before the Commission on exceptions to an intermediate decision, such motion shall be filed no later than the date for the filing of briefs on exceptions.

(c) Notice of oral argument. The Commission shall rule on requests for oral argument, and if argument is allowed, the Commission shall notify the parties of the time and place set for argument, the amount of time allowed each party, and the issue or issues on which oral argument is to be heard. Unless otherwise ordered by the Commission, oral argument shall be limited to matters properly raised on the record and in the briefs before the Commission.

(d) Use of documents at oral argument. Charts, graphs, maps, tables, and other written material may be presented to the Commission at oral argument only if limited to facts in the record of the case being argued and if copies of such documents are filed with the Secretary and served on all parties at least seven days in advance of the argument. Enlargements of such charts, graphs, maps, and tables may be used at the argument provided copies are filed and served as required by this paragraph.

(a) At the conclusion of a proceeding on the record with the opportunity for a hearing, the Commission shall issue a final decision which either:

(1) Adopts an intermediate decision prepared by a presiding officer; or

(2) Rules upon the matters that are before the Commission, or provides explanation for why such rulings are not being provided.

(b) Commission decisions shall be based on the evidence entered into the record, and consider the arguments filed on brief. Argument provided in comments may further inform the Commission's decision, but have no evidentiary standing and are not required to be addressed in the final decision.

(c) An intermediate decision may be adopted by the Commission in whole or in part. When an intermediate decision is adopted in part, the Commission shall explain its decisions regarding both what is and is not adopted.

(d) When exceptions, or objections to exceptions, to an intermediate decision are filed pursuant to § 3010.336 by any party to the proceeding, the Commission shall consider and rule upon such exceptions, or objections to exceptions in its final decision.

(e) Commission decisions shall be filed in the docket and served on all parties. Commission decisions shall be part of the record of the proceeding.

(a) An intermediate decision shall be issued by the presiding officer which rules upon the matters that are before the Commission, or provides explanation for why such rulings are not being provided, in a proceeding on the record with the opportunity for a hearing when:

(1) The Commission is not sitting en banc; or

(2) The presiding office has been directed to issue an intermediate decision by Commission notice or order.

(b) Intermediate decisions shall be based on the evidence entered into the record, and shall consider the arguments filed on brief. Arguments provided in comments may further inform the presiding officer's decision, but are not required to be addressed in the intermediate decision.

(c) Intermediate decisions shall be filed in the docket and served on all parties. Intermediate decisions shall be part of the record of the proceeding.

(d) Intermediate decisions are subject to review by the Commission and subject to challenge by parties to the proceeding through the filing of exceptions pursuant to § 3010.336. After review and consideration of the exceptions filed, intermediate decisions may be adopted by the Commission, in whole or in part, as part of the final decision in the proceeding.

(e)(1) The Commission may, at any time, direct the omission of an intermediate decision and the certification of the record for the Commission's consideration sitting en banc. Parties to a proceeding may, by motion, request the omission of an intermediate decision and the certification of the record for the Commission's consideration sitting en banc. Motions shall specify:

(i) The concurrence of other parties; and

(ii) Whether opportunity for filing briefs or presenting oral argument to the Commission is desired or waived.

(2) Failure of any party to object to such request shall constitute a waiver of any objections. Motions shall be filed no later than the deadline for the filing of briefs. In either instance, the decision to omit an intermediate decision shall be based upon the consideration of the novelty of the matters before the Commission, and the timely and efficient operation of the docket.

(a) Briefs on exceptions and opposing exceptions. Any party in a proceeding may file exceptions to any intermediate decision by first filing a notice of intent to file a brief on exceptions with the Commission within seven days after the date of issuance of the intermediate decision or such other time as may be fixed by the Commission. The brief on exceptions shall be filed with the Commission within 30 days after the date of issuance of the intermediate decision or such other time as may be fixed by the Commission. Any party to a proceeding may file a response to briefs on exceptions within 20 days after the time limited for the filing of briefs on exceptions or such other time as may be fixed by the Commission. No further response will be entertained unless the Commission, upon motion for good cause shown or on its own initiative, so orders.

(b) Filing and contents. Briefs on exceptions and briefs opposing exceptions shall be filed in accordance with § 3010.330. In briefs on exceptions, the discussion of evidence, reasons and authorities shall be specifically directed to the findings, conclusions and recommendations in the intermediate decision to which exception is taken. Briefs on exceptions should not include a discussion of evidence and authorities on matters and issues to which no exception to the intermediate decision is taken. Briefs on exceptions and briefs opposing exceptions need not contain a statement of the case to the extent that it was correctly stated in either the intermediate decision or the brief on exceptions of another party to which reference is made.

(c) Failure to except results in waiver. Any party who fails to except or object to any part of an intermediate decision in its brief on exceptions may not thereafter raise such exceptions or objections which shall be deemed to have been waived.
