What must happen after an arraignment hearing?

After an arraignment hearing, it's essential for the hearing date to be confirmed by the defendant's appearance in court. The arraignment is a crucial step in the criminal process, where the accused is formally charged and enters a plea. Following this, the court typically sets a date for future proceedings, such as a pre-trial or trial. The confirmation of this date ensures that all parties involved—including the defendant, legal representation, and the prosecution—are aware of when to return to court for the next steps in the judicial process.

In contrast to this, the other options do not accurately reflect standard protocol following an arraignment. Elevating the matter to the Supreme Court does not happen at this stage; most cases are addressed in lower courts unless specific legal grounds warrant further action. Automatic release of the accused does not occur simply because of an arraignment; bail conditions or custody may still need to be considered based on the nature of the charges and the risks involved. Finally, declaring a mistrial is unrelated to the arraignment process and typically arises from issues during a trial itself, not during the preliminary steps of charging an individual.
