If, during the course of a public session, evidence is submitted that was not previously presented at executive session and that the Commission determines may defame, degrade, or incriminate any person, the provisions of Sec. 702.6 shall apply and such extensions, recesses or continuances of the public session shall be ordered by the Commission, as it deems necessary. The time and notice requirements of Sec. 702.6 may be modified by the Commission provided reasonable notice of a scheduled executive session is afforded such person; the Commission may, in its discretion, strike such evidence from the record, in which case the provisions of Sec. 702.6 shall not apply.
