Voters approved this governmental change at the November 6, 2012, election with 62,469 voting for the transition and 37,368 against. Previously, Frederick County had been governed by a five-member county commission that could only legislate in local matters with the prior consent of the Maryland General Assembly. Even that authority was limited to areas authorized by the General Assembly, enabling legislation, or public local laws. As a charter county, Frederick County is now governed by a seven-member county council, with five elected from districts and two elected at-large. A popularly elected county executive is responsible for providing direction, supervision, and administrative oversight of all executive departments, agencies, and offices. The council has broad power to act on most local matters. Jan H. Gardner was
