The hearing officer shall admit any relevant evidence if the evidence is the sort of evidence upon which responsible persons are accustomed to rely in the conduct of serious affairs, regardless of the existence of any common law or statutory rule which might make such evidence improper. The hearing officer shall admit such improper evidence for any purpose but such evidence shall not be sufficient itself to support a finding unless the evidence would be admissible over objection in a civil action under the formal rules of evidence or unless the evidence is corroborated by otherwise admissible evidence.
