Which of the following roles controls the courtroom?

The role that controls the courtroom is the judge. The judge is responsible for ensuring that the legal proceedings are conducted fairly, efficiently, and within the boundaries of the law. They have the authority to make rulings on various aspects of the trial, including the admissibility of evidence, the conduct of attorneys and witnesses, and the overall management of the court's schedule and proceedings.

Judges also protect the rights of all parties involved in the case, maintaining order in the courtroom and ensuring the rules of the legal system are followed. This key function is essential in upholding justice and ensuring that the trial proceeds without disruption.

While the defense attorney and prosecutor play crucial roles in presenting their cases and representing their clients' interests, they do not control the courtroom environment or the procedures; that responsibility lies with the judge. The court clerk, on the other hand, assists in the administration of the court but does not have control over the courtroom itself or the proceedings.
