In accordance with Section 4-178 of the Connecticut General Statutes, the following rules of evidence shall be followed in contested cases:
The Council shall give effect to the rules of privilege recognized by law in Connecticut. Subject to these requirements and subject to the right of any party or intervenor to cross examine, any testimony may be received in written form.
The Council may exclude evidence that is not probative or material and that tends not to prove or disprove a matter in issue.
Pursuant to Section 16-50j-25 of the Regulations of Connecticut State Agencies, in its discretion, the Council may accept any oral or written testimony.
Pre-filed testimony and other documentary evidence shall be produced under oath. Such evidence shall be received by the Council in written form to expedite the public hearing.
Cross examination may be conducted by any party or intervenor if it is required by the Council for full and true disclosure of the facts. Witnesses may be cross-examined on any pre-filed testimony and documents submitted as evidence. If the Council proposes to consider a limited appearance statement as evidence, the Council shall give all parties and intervenors an opportunity to challenge or rebut the statement and to cross-examine the person who makes the statement.
The Council may take administrative notice of facts in accordance with Section 4-178 of the Connecticut General Statutes, including prior decisions and orders of the Council and any exhibit admitted as evidence by the Council in a prior hearing of a contested case.
