(a) If all parties waive their right to appear before the
administrative law judge, it shall not be necessary for the
administrative law judge to give notice of, or conduct, an oral
hearing. A waiver of the right to appear shall be made in writing and
filed with the Chief Administrative Law Judge or the administrative law
judge assigned to hear the case. Such waiver may be withdrawn by a
party for good cause shown at any time prior to the mailing of the
decision in the claim. Even though all of the parties have filed a
waiver of the right to appear, the administrative law judge may,
nevertheless, after giving notice of the time and place, conduct a
hearing if he or she believes that the personal appearance and
testimony of the party or parties would assist in ascertaining the
facts in issue in the claim. Where a waiver has been filed by all
parties, and they do not appear before the administrative law judge
personally or by representative, the administrative law judge shall
make a record of the relevant documentary evidence submitted in
accordance with this part and any further written stipulations of the
parties. Such documents and stipulations shall be considered the
evidence of record in the case and the decision shall be based upon
such evidence.
(b) Except as provided in Sec. 725.456(a), the unexcused failure of
any party to attend a hearing shall constitute a waiver of such party's
right to present evidence at the hearing, and may result in a dismissal
of the claim (see Sec. 725.465).
