The administrative law judge shall, within 20 days after the
official termination of the hearing, deliver by mail, or otherwise, to
the office of the district director having original jurisdiction, the
transcript of the hearing, other documents or pleadings filed with him
with respect to the claim, together with his signed compensation order.
Upon receipt thereof, the district director, being the official
custodian of all records with respect to such claims within his
jurisdiction, shall formally date and file the transcript, pleadings,
and compensation order (original) in his office. Such filing shall
be accomplished by the close of business on the next succeeding working
day, and the district director shall, on the same day as the filing was
accomplished, send by certified mail a copy of the compensation order to
the parties and to representatives of the parties, if any. Appended to
each such copy shall be a paragraph entitled ``proof of service''
containing the certification of the district director that the copies
were mailed on the date stated, to each of the parties and their
representatives, as shown in such paragraph.
