Conduct and exclusion of persons; petition to rescind exclusion.

1. Any person appearing in a proceeding shall conform to recognized standards of ethical and courteous conduct required before the courts of this State. Every party to a hearing, his or her representative and all spectators shall conduct themselves in a respectful manner. 2. Contumacious conduct by any person at a hearing before the Commissioner is a ground for the exclusion of the person from the hearing and for the summary exclusion of the person from further participation in subsequent proceedings relating thereto. The Commissioner may bar any person excluded pursuant to this subsection from attending any further proceedings of the Commissioner. 3. A person excluded from proceedings by the Commissioner pursuant to subsection 2 may petition the Commissioner to rescind the exclusion. The Commissioner will grant the petition if he or she finds sufficient evidence that the contumacious conduct that led to the exclusion of the person will not reoccur.
