§ 458.78 Rules of evidence.
The technical rules of evidence do not apply. Any evidence may be received, except that an Administrative Law Judge may exclude any evidence or offer of proof which is immaterial, irrelevant, unduly repetitious, or customarily privileged. Every party shall have a right to present his case by oral and documentary evidence and to submit rebuttal evidence.
