1720.425—Presentation and admission of evidence.
(a)
All witnesses at a hearing for the purpose of taking evidence shall testify under oath or affirmation which shall be administered by the administrative law judge. Every party shall have the right to present such oral or documentary evidence and to conduct such cross-examinations as may be required for a full and true disclosure of the facts. The administrative law judge shall receive relevant and material evidence, rule upon offers of proof and exclude all irrelevant, immaterial or unduly repetitious evidence.
(b)
Evidence shall not be excluded merely by application of technical rules governing its admissibility, competency, weight or foundation in the record; but evidence lacking any significant probative value, or substantially tending merely to confuse or extend the record, shall be excluded. The administrative law judge may allow arguments on the admissibility of evidence by analogy to the Federal Rules of Evidence currently applicable in the United States District Courts of the United States.
(c)
When offered evidence is excluded, the party offering the same shall be permitted to state on the record an offer of proof with respect thereto and rejected exhibits, adequately marked, shall on request of the party offering the same be retained in the record for purposes of review. Evidence may be received subject to deferred ruling on objections to its admissibility.
(d)
Objections to evidence shall be timely made and shall specify the particular ground of objection without argument except as argument may be expressly required by the administrative law judge. Formal exception to an adverse ruling is unnecessary.
