Mississippi Code Title 57. Planning, Research and Development § 57-64-13

(1) Any power, authority or responsibility exercised or capable of being exercised by a local government unit of this state may be exercised and carried out jointly with any other local government unit of this state or with a foreign governmental unit of another state, any state board, agency or commission and any public agency of the United States, to the extent that the laws of the United States permit such joint exercise or enjoyment.

(2) No such power, authority and responsibility may be exercised under the provisions of this chapter which will have the effect of abolishing any office which is held by a person elected by the citizenry.

(3) No agreement made under this chapter shall be entered into by any local government unit without the approval by resolution on the minutes of the governing body of that local government unit.

(4) Any joint undertaking entered into under this chapter shall be evidenced by written contractual agreements for joint or cooperative action to provide services and facilities pursuant to the provisions of this chapter which agreements shall be approved by the MDA. Appropriate action by ordinance, resolution or otherwise pursuant to the law controlling the participating local government units or agencies shall be necessary before any such agreement shall be in force.

(5) An alliance created pursuant to this chapter may take any action with respect to a project that any local government unit member may take. If one (1) member of the alliance shall have authority to undertake a particular project or pursue a particular action with respect to such project, then the alliance shall have identical authority so to do. No local government unit shall be precluded from joining an alliance, and it shall not be the basis for denying an application for a certificate of convenience and necessity by the MDA, solely because the alliance may have power to take actions that the local government unit acting alone could not take.
