In 1890, as a result of the Local Government (Scotland) Act 1889, virtually all of the powers and duties of the commissioners passed to the newly created county councils. The commissioners continued to exist, however, meeting once a year to elect a convener and to appoint members to the Joint Standing Committee that was responsible for the county constabulary. The other members of the committee were nominated by the county council, and it was chaired by the sheriff of the county.
