Miss. Code § 61-3-17
In the acquisition of property by eminent domain proceedings authorized by this chapter, an authority shall proceed in the manner provided by Chapter 27 of Title 11, Mississippi Code of 1972, and as elsewhere provided by law. For the purpose of making surveys and examinations relative to eminent domain proceedings, it shall be lawful for the authority to enter upon the land, doing no unnecessary damage. Notwithstanding the provisions of any other statute or other law, an authority may take possession of any property to be acquired by eminent domain proceedings at any time after the commencement of such proceedings upon a specific finding by the authority of the public necessity for the immediate acquisition of the property pursuant to Section 11-27-81 et seq., and compliance with all the provisions of Section 11-27-81 et seq., including the provisions for making a deposit. The authority shall not be precluded from abandoning such proceedings at any time prior to final order and decree of the court having jurisdiction of such proceedings. The authority shall be liable to the owner of the property for any damage done to the property during possession thereof by the authority.
