At any time prior to the close of the hearing record, the complaint
or answer may be amended with the permission of the Administrative Law
Judge and on such terms as he/she may approve. When issues not raised by
the pleadings are reasonably within the scope of the original complaint
and are tried by express or implied consent of the parties, they shall
be treated in all respects as if they had been raised in the pleadings,
and such amendments may be made as necessary to make them conform to the
evidence. Such amendments shall be allowed when justice and the
presentation of the merits are served thereby, provided there is no
prejudice to the objecting party's presentation on the merits. A
continuance in the hearing may be granted or the record left open to
enable the new allegations to be addressed. The presiding Administrative
Law Judge may, upon reasonable notice and upon such terms as are just,
permit supplemental pleadings setting forth transactions, occurrences or
events which have happened since the data of the pleadings and which are
relevant to any of the issues involved.
