[§392-73]  Procedure.  The referee shall
not be bound by common law or statutory rules of evidence or by technical rules
of procedure, but any hearing or appeal before the same shall be conducted in
such manner as to ascertain the substantial rights of the parties.  No person
shall participate on behalf of the director in any case in which that person
has a direct or indirect interest.  A record shall be kept of all testimony and
proceedings in connection with an appeal, but the testimony need not be transcribed
unless further review is initiated.  Witnesses subpoenaed pursuant to this
section shall be allowed fees at a rate fixed by the department and such fees
shall be deemed part of the expenses of administering this chapter. [L 1969, c
