Ohio Rev. Code § 105.21
The governor shall appoint four competent persons who shall constitute a council of commissioners to be known as the state council of uniform state laws. Terms of office shall be for three years, commencing on the sixth day of June and ending on the fifth day of June, except that the appointment made to fill the vacancy existing on December 8, 1972, shall be made for a term ending June 5, 1973; and upon expiration of the term ending July 23, 1974, the new term which succeeds it shall commence on July 24, 1974, and end on June 5, 1977. Each commissioner shall hold office from the date of appointment until the end of the term for which the commissioner was appointed. The governor may remove any one or all of the commissioners for cause, and the governor may fill any vacancy by appointment. Any commissioner appointed to fill a vacancy occurring prior to the expiration of the term for which the commissioner's predecessor was appointed shall hold office for the remainder of such term. Any commissioner shall continue in office subsequent to the expiration date of the commissioner's term until a successor takes office, or until a period of sixty days has elapsed, whichever occurs first.
