First, is this "hearing" a trial, some kind of pre-trial motion (to dismiss, etc.) or the first accusatory "arraignment"?
You're also going to need two new characters, a sherrif/Courtroom deputy (bailiff), who introduces the judge to the court and calls the cases for hearing. "All rise for the Honorable Judge Judy." Everybody stands. "the Court calls to order the case of the People v. Joe Blow" (that's usually the bailiff/court room deputy that does all of that. And you'll need a court reporter, too, who sits next to the Judge and takes down all of what is said in the court on a dictation machine.
Once the case is called, the parties and their lawyers all step up before the judge (bench) and argue their sides of the issue with the prosecutor going first (or if it's a motion, the movant [person who filed the motion] going first.) The defense goes second and last if there is time allowed for any rebuttals by the prosecution.
I hope this helps!
