Supreme Court Commission
In 1875, the Constitution of Ohio was amended to provide for the Supreme Court Commission. The amendment reads in part: "A commission, which shall consist of five members, shall be appointed by the governor, with the advice and consent of the Senate, the members of which shall hold office for the term of three years from and after the first day of February, 1876, to dispose of such part of the business then on the dockets of the Supreme Court, as shall, by arrangement between said commission and said court, be transferred to such commission; and said commission shall have like jurisdiction and power in respect to such business as are or may be vested in said court; and the members of said commission shall receive a like compensation for the time being, with the judges of said court."

Commission of 1876
On February 2, 1876, Ohio Governor Rutherford B. Hayes appointed the following six members:
 * Josiah Scott of Crawford County
 * William Wartenbee Johnson of Lawrence County
 * D. Thew Wright of Hamilton County
 * Richard A. Harrison of Franklin County
 * Henry C. Whitman of Hamilton County
 * Luther Day of Portage County

Harrison refused the appointment, and Thomas Q. Ashburn of Clermont County was seated March 16, 1878. The commission sat until February 2, 1879, and "assisted in bringing up the docket which had fallen behind the reasonable time for trial."
