No member shall serve more than two consecutive full terms on the board, effective January 1, 1990. A member of the board may be removed by the Governor for neglect of duty or just cause. Before taking office, the members of the board shall take and file with the Secretary of State the constitutional oath of office required by Section 279 of the Constitution of Alabama of 1901.
