Hawaii Revised Statutes Division 5. Crimes and Criminal Proceedings § 706-607

(1) When a person prosecuted for a class C felony, misdemeanor, or petty misdemeanor is a chronic alcoholic, narcotic addict, or person suffering from mental abnormality and the person is subject by law to involuntary hospitalization for medical, psychiatric, or other rehabilitative treatment, the court may order such hospitalization and dismiss the prosecution. The order of involuntary hospitalization may be made after conviction, in which event the court may set aside the verdict or judgment of conviction and dismiss the prosecution.

(2) The court shall not make an order under subsection (1) unless it is of the view that it will substantially further the rehabilitation of the defendant and will not jeopardize the protection of the public.
