Miss. Code Ann. § 71-5-7

If at any time the provisions of this chapter requiring the payment of contributions and benefits shall be held invalid under the Constitution of this state by the Supreme Court of this state or invalid under the United States Constitution by the Supreme Court of the United States, the department shall forthwith requisition from the unemployment trust fund all monies therein standing to the credit of the department, and shall deposit such monies, together with any other monies in the unemployment compensation fund, in any banks or public depositories in this state in which general funds of the state may be deposited. If within six (6) months after the date of such decision the Legislature of this state enacts a new unemployment compensation law, such monies shall be paid into the unemployment compensation fund established thereunder. If within such six-month period the Legislature of this state has not enacted a new unemployment compensation law, the department shall, under regulations prescribed by it, refund, without interest, to each employer by whom contributions have been paid, his pro rata share of the total contributions paid under this chapter. Any interest or earnings of the fund shall be available to the department to pay for the costs of making such refunds. The provisions of this chapter, so far as necessary to the execution by the department of the duties prescribed in this section and to the performance of such other acts as are incidental to the termination of its duties under this chapter, shall remain in full force and effect until the completion thereof.
