Section 2402.150 Bias or

affidavit setting forth allegations of personal bias, prejudice, or
disqualification of a presiding Hearing Officer. The Director shall determine
this issue as part of the record of the case. When a Hearing Officer is
disqualified, or it becomes impractical for him to continue, another presiding
officer may be assigned unless it is further shown that substantial bias or
prejudice will result from the assignment.
b) The Hearing Officer may at any time voluntarily disqualify
himself.
