Miss. Code Ann. § 43-29-17

The county department shall at once report to the State Department its decision upon each application. If an application is not acted upon by the county department within thirty (30) days after the filing of the application, or is denied or revoked, the applicant may appeal to the State Department in the manner and form prescribed by rules and regulations. The State Department shall upon receipt of such an appeal give the applicant an opportunity for a fair hearing. The State Department may also, upon its own motion, review any decision of a county department and may consider any application upon which a decision has not been made by the county department within a reasonable time.

The State Department may make such additional investigations as it may deem necessary and shall make such decision as to the granting of assistance and the amount of assistance to be granted the applicant as in its opinion is justified and in conformity with the provisions of this chapter. All decisions of the State Department shall be binding upon the county department involved and shall be complied with by such county department.
