D.C. Mun. Regs. tit. 17, r. 17-1728
The parties at a hearing shall maintain decorum and good order at all time. A Hearing Examiner may exclude or have removed from the hearing room any person violating an order of the Hearing Examiner.
The Hearing Examiner, Director, or board may bar counsel from further participation in a hearing for disruptive conduct.
If counsel has been barred from participating in a hearing, a Hearing Examiner may proceed with the hearing if consistent with the due process rights of the parties. Otherwise, the Hearing Examiner shall adjourn the hearing to give the party whose counsel has been barred an opportunity to secure new representation expeditiously.
A counsel who has been barred from participating in a hearing may seek, and a Hearing Examiner may grant, reinstatement to participate in the hearing on terms as the Hearing Examiner prescribes. The Hearing Examiner shall not permit a reinstatement application to delay the proceedings.
