As supplemental to and in addition to all other power and authority which may now be vested in the Governor of the State of Mississippi by the constitution or statutes, or both, or any power or authority which may be vested in him by common law as Governor, as such, the Governor of the State of Mississippi is hereby vested with the authority to close any or all state parks in the State of Mississippi when, in his discretion, he determines such closure would be to the best interest of the county or counties in which any state park or parks may be situated, or whenever he so determines such to be to the best interest of the State of Mississippi. The said Governor, as such, is also vested with such supplemental and additional authority to close any or all state parks in the State of Mississippi when, in his discretion, he determines such closure will promote or preserve the public peace, order or tranquility of the county or counties in which such park or parks may be situated, or that such closure will promote or preserve the public peace, order or tranquility in and of the State of Mississippi.

The fact that the power and authority to close any or all of the state parks may be by some other statute of the State of Mississippi now or hereafter vested in some other person or officer or commission shall not cause this section and any other such law or laws to be in conflict nor shall same be construed to be in conflict with each other. Such power and authority vested in each such commission or person or officer, as the case may be, may be exercised by each or either, independent of any other such commission of person or persons or officer or officers.
