A court of inquiry to investigate any matter may be convened by the governor whether or not the persons involved have requested such investigation. Such court shall be composed of one or more officers. A court of inquiry shall, without delay, report to the governor a statement of the facts of the matter under investigation and, when required, the evidence adduced and an opinion with recommendations thereon. The procedure to be followed by such courts shall be as nearly as may be that prescribed for courts of inquiry of the armed forces of the United States, as directed by regulations issued under the authority of this chapter.
