821.38—Evidence.
Each party shall have the right to present a case-in-chief, or defense, by oral and documentary evidence, to submit evidence in rebuttal, and to conduct such cross-examination as may be required for a full and true disclosure of the facts. Hearsay evidence (including hearsay within hearsay, where there are acceptable circumstantial indicia of trustworthiness) shall be admissible. All material and relevant evidence should be admitted, but the law judge may exclude unduly repetitious evidence.
