Hawaii Organic Act § 83

That the laws of Hawaii relative to the judicial department, including civil and criminal procedure, except as amended by this Act, are continued in force, subject to modification by Congress, or the legislature. The provisions of said laws or any laws of the Republic of Hawaii which require juries to be composed of aliens or foreigners only, or to be constituted by impaneling natives of Hawaii only, in civil and criminal cases specified in said laws, are repealed, and all juries shall hereafter be constituted without reference to the race or place of nativity of the jurors; but no person who is not a citizen of the United States and twenty-one years of age and who cannot understandingly speak, read, and write the English language shall be a qualified juror or grand juror in the Territory of Hawaii. No person shall be convicted in any criminal case except by unanimous verdict of the jury. No plaintiff or defendant in any suit or proceeding in a court of the Territory of Hawaii shall be entitled to a trial by a jury impaneled exclusively from persons of any race. Until otherwise provided by the legislature of the Territory, grand juries may be drawn in the manner provided by the Hawaiian statutes for drawing petty juries, and shall sit at such times as the circuit judges of the respective circuits shall direct; the number of grand jurors in each circuit shall be not less than thirteen, and the method of the presentation of cases to said grand jurors shall be prescribed by the supreme court of the Territory of Hawaii. The several circuit courts may subpoena witnesses to appear before the grand jury in like manner as they subpoena witnesses to appear before their respective courts.
