Section 332 - Procedures in general(a) Burden of proof.--Except as may be otherwise provided in section 315 (relating to burden of proof) or other provisions of this part or other relevant statute, the proponent of a rule or order has the burden of proof.(b) Admissibility of evidence.--Any oral or documentary evidence may be received, but the commission shall as a matter of policy provide for the exclusion of irrelevant, immaterial or unduly repetitious evidence. No sanction shall be imposed or rule or order be issued except upon consideration of the whole record or such portions thereof as may be cited by any party and as supported by and in accordance with the reliable, probative and substantial evidence.(c) Submission of evidence.--Every party is entitled to present his case or defense by oral or documentary evidence, to submit rebuttal evidence and to conduct such cross-examination as may be required for a full and true disclosure of the facts. The commission may, by rule, adopt procedures for the submission of all or part of the evidence in written form.(d) Record, briefs and argument.--The transcript of a public input hearing, the transcript of testimony and exhibits, together with all papers and requests filed in the proceeding, constitutes the exclusive record for decision, and shall be available for inspection by the public. Briefing and oral argument shall be held in accordance with rules established by the commission. For the purpose of this section, a public input hearing is a hearing held in the service area at which the ratepayers may offer testimony, written or otherwise, relating to any matter which has a bearing on the proceeding.(e) Official notice of facts.--When the commission's decision rests on official notice of a material fact not appearing in the evidence in the record, upon notification that facts are about to be or have been noticed, any party adversely affected shall have the opportunity upon timely request to show that the facts are not properly noticed or that alternative facts should be noticed. The commission in its discretion shall determine whether written presentations suffice, or whether oral argument, oral evidence, or cross-examination is appropriate in the circumstances. Nothing in this subsection shall affect the application by the commission in appropriate circumstances of the doctrine of judicial notice.(f) Actions of parties and counsel.--Any party who shall fail to be represented at a scheduled conference or hearing after being duly notified thereof, shall be deemed to have waived the opportunity to participate in such conference or hearing, and shall not be permitted thereafter to reopen the disposition of any matter accomplished thereat, or to recall for further examination of witnesses who were excused, unless the presiding officer shall determine that failure to be represented was unavoidable and that the interests of the other parties and the public would not be prejudiced by permitting such reopening or further examination. If the actions of a party or counsel in a proceeding shall be determined by the commission, after due notice and opportunity for hearing, to be obstructive to the orderly conduct of the proceeding and inimical to the public interest, the commission may reject or dismiss any rule or order in any manner proposed by the offending party or counsel, and, with respect to counsel, may bar further participation by him in any proceedings before the commission.(g) Decision of administrative law judge.--In all on-the-record proceedings referred to, an administrative law judge under section 331(b) (relating to powers of commission and administrative law judges), hearings shall be commenced by the administrative law judge within 90 days after the proceeding is initiated, and he shall render a decision within 90 days after the record is closed, unless the commission for good cause by order allows an extension not to exceed an additional 90 days.(h) Exceptions and appeal procedure.--Any party to a proceeding referred to an administrative law judge under section 331(b) may file exceptions to the decision of the administrative law judge with the commission, in a form and manner and within the time to be prescribed by the commission. The commission shall rule upon such exceptions within 90 days after filing. If no exceptions are filed, the decision shall become final, without further commission action, unless two or more commissioners within 15 days after the decision request that the commission review the decision and make such other order, within 90 days of such request, as it shall determine. The Office of Trial Staff and the chief counsel shall be deemed to have automatic standing as a party to such proceeding and may file exceptions to any decision of the administrative law judge under this subsection.(i) Review of testimony.--Any party of record in an investigation or inquiry by or hearing before the commission or its representative whose testimony is recorded electronically and subsequently transcribed shall, upon request, be permitted to review the recording to ensure that it has been transcribed accurately. The commission may impose a fee in an amount not exceeding the actual costs involved for making the recording available. Any request to review the recording must be made within the time prescribed by commission regulation, and such request shall not be used to unreasonably delay commission proceedings. This section shall not be construed to require the electronic recording of testimony. The official record of a proceeding shall be the written transcript. 1978 , July 1, P.L. 598, No. 116, § 1, effective in 60 days.
