Miss. Code Ann. § 81-8-11

It is the purpose of this chapter to permit orderly development of banking institutions on a national basis in accordance with the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994, Public Law 103-328. It is not the purpose of this chapter to authorize interstate banking on any basis other than as expressly provided in this chapter and by federal law. To that end, if any provision of this chapter pertaining to the terms, conditions and limitations of interstate acquisitions of Mississippi banks and bank holding companies is determined to be inconsistent with or contrary to any provision of federal law, such provision of this chapter shall be null and void with respect to such federal law; however, any transaction which has been lawfully consummated pursuant to this chapter prior to a determination of invalidity shall be unaffected by such determination.
