If all parties waive their right to appear before the administrative
law judge or to present evidence or argument personally or by
representative, it shall not be necessary for the administrative law
judge to give notice of and conduct an oral hearing. A waiver of the
right to appear and present evidence and allegations as to facts and law
shall be made in writing and filed with the Chief Administrative Law
Judge or the administrative law judge. Where such 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 written evidence submitted by the
parties, together with any pleadings they may submit with respect to the
issues in the case. Such documents shall be considered as all of the
evidence in the case and the decision shall be based on them.
