Haw. Rev. Stat. § 641-17: Interlocutory appeals from circuit courts, criminal matters.

Upon application made within the time provided by the rules of court, an appeal in a criminal matter may be allowed to a defendant from the circuit court to the intermediate appellate court, subject to chapter 602, from a decision denying a motion to dismiss or from other interlocutory orders, decisions, or judgments, whenever the judge in the judge's discretion may think the same advisable for a more speedy termination of the case. The refusal of the judge to allow an interlocutory appeal to the appellate court shall not be reviewable by any other court.
