(a) Method of service. Notices of hearings, decisions, orders, and
other papers may be served personally or by registered or certified
mail or by telegraph.
(b) Upon whom served. Unless otherwise provided in the rules and
regulations in this subchapter, all papers except complaints, petitions,
and papers relating to requests for appearance or production of documents,
shall be served upon all counsel of record and upon parties not represented
by counsel or by their agents designated by them or by law and upon
the panel, or its designated officers or agents, where appropriate.
Service upon such counsel or representative shall constitute service
upon the party, but a copy also shall be transmitted to the party.

to the panel or its designated representative, or the individual conducting
the proceeding, a written statement of such service. Failure to file

Proof of service, except where otherwise provided, shall be required
only if subsequent to the receipt of a statement of service a question
is raised with respect to proper service.
