Haw. Rev. Stat. § 380-14
(c) Whenever it is charged that any person has engaged in an unfair labor practice within the meaning of section 377-7(5), (6), (7), (8), and (9), the preliminary investigation of that charge shall be made forthwith and given priority over all other cases except cases of like character in the office where it is filed or to which it is referred. If, after the investigation, the board has reasonable cause to believe the charge is true, it shall petition any circuit court of the State within any circuit where the unfair labor practice in question has occurred, is alleged to have occurred, or wherein the person resides or transacts business, for appropriate injunctive relief pending the final adjudication of the board with respect to that matter. Upon the filing of any such petition, the circuit court shall have jurisdiction to grant such injunctive relief or temporary restraining order as it deems just and proper, notwithstanding any other provision of law or rule of court; provided that no temporary restraining order shall be issued without notice unless a petition alleges that substantial and irreparable injury to the charging party will be unavoidable and the temporary restraining order shall be effective for no longer than five days and will become void at the expiration of that period; provided further that the board shall not apply for any restraining order under section 377-7(5), (6), (7), (8), and (9) if a charge against the employer under section 377-6(2) has been filed and after the preliminary investigation, the board has reasonable cause to believe that the charge is true and that a complaint should be issued. Upon the filing of any such petition, the courts shall cause notice thereof to be served upon any person involved in the charge and the person, including the charging party, shall be given an opportunity to appear by counsel and present any relevant testimony; provided that for the purposes of this subsection, circuit courts shall be deemed to have jurisdiction of a labor organization in:
