HRS §806-49
What happens when you plead not guilty
When you are formally charged and say 'not guilty' in court, that plea automatically means you are asking for a trial by jury. The court will then set up a jury for your trial in the usual way.
The statute, as written — Arraignment; plea of not guilty
If any person being arraigned upon any indictment for any offense pleads thereto a plea of "not guilty", the person shall by that plea without any further form, be deemed to have put oneself upon the country for trial, and the court shall in the usual manner order a jury for the trial of the person accordingly.
