Answer:
Preliminary hearings take place in front of a judge, but the defense lawyer is also present.
Step-by-step explanation:
Preliminary hearings take place in front of a judge only, but the defendant's lawyer is also present. A jury is never present at a preliminary hearing, since its main purpose is to establish if there exists a reasonable cause to carry on a trial. If we want to be more exact, a bailiff (court police officer) should also be present.
