If, during the course of the hearing, a party first becomes aware of evidence of bias or other grounds for disqualification, the party may move for recusal but must establish the grounds by the introduction of evidence into the record.
If the workers' compensation commissioner or deputy workers' compensation commissioner determines that recusal is appropriate, that person shall withdraw. If that person determines that withdrawal is not required, that person shall enter an order to that effect.
This rule is intended to implement Iowa Code section 17A.17.
