Mississippi Code Title 57. Planning, Research and Development § 57-5-11

Each municipality within this state shall have the right to apply to the board for a certificate of public convenience and necessity from the board as to whether the general welfare requires that such municipality enter into the development of such a “standard” industrial park or district. In determining whether such certificate shall be issued, the board may hold hearings, make such investigation as may be desired, and shall have power to summon witnesses, administer oaths, hear testimony and make a record of all things had and done at such hearings or investigations, and to order issued such certificates of convenience and necessity as to the board may seem advisable.
