Rule 10.7 Excusals from courtroom.

Only the judge can tell someone to leave the courtroom during a hearing. This includes lawyers, witnesses who have already testified, and the parties involved in the case.

No one else, including other lawyers or court staff, has the authority to excuse or dismiss someone from the courtroom. If you are in the courtroom for a proceeding, you need to wait for the judge to tell you that you may leave.
