The Judges or Stewards shall allow a full presentation of evidence and are not bound by the technical rules of evidence. However, the Judges or Stewards may disallow evidence that is irrelevant or unduly repetitive of other evidence. They shall have the authority to determine, in their sole discretion, the weight and credibility of any evidence or testimony, or both. The Judges or Stewards may admit hearsay evidence if in the opinion of the Judges or Stewards it is the type of evidence that is commonly relied on by reasonably prudent people.
