22 Miss. Code. R. 20-16-114
The hearing need not be conducted according to technical rules relating to evidence and witnesses. The hearing officer shall admit evidence which is the sort of evidence on 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 improper the admission of such evidence over objection in civil actions, and which is not irrelevant, immaterial, unduly repetitious, or otherwise unreliable or of little probative value. Hearsay evidence may be used for the purpose of supplementing or explaining other evidence, but upon timely objection shall not be sufficient in itself to support a finding unless it would be admissible over objection in civil actions.
