The Director of Finance must assign rooms in the Capitol to the Secretary of State, Auditor, Treasurer, the Department of Revenue and such other officers as may be designated by law, or which, in the discretion of the Governor, should have such offices, and, in the absence of any legislative provision, designate the purposes to which other rooms are to be applied. The director may supply offices or quarters for state officers or departments of the state outside of the State Capitol, within the City of Montgomery, when, in the discretion of the Governor, the public interest and welfare will be subserved or promoted thereby.
