(2) All expert testimony to be offered in rebuttal shall be filed and served within the time limits established by the commission or the presiding hearing officer, unless the commission or the presiding hearing officer determines that such testimony need not be reduced to writing.
(B) For purposes of this rule, "commencement of the hearing" means the scheduled date for beginning the hearing at which expert testimony is to be offered.
(C) Notwithstanding paragraph (A) of this rule, the presiding hearing officer may, in his or her discretion, permit an expert witness to present additional oral testimony at the hearing, provided that such testimony could not, with reasonable diligence, have been filed and served within the time limits established by the commission or the presiding hearing officer or the presentation of such testimony will not unduly delay the proceeding or unjustly prejudice any other party.
