If at any time the Governor shall find that the provisions of this chapter requiring the payment of contributions and benefits have been held invalid under the Constitution of this state by the Supreme Court of this state or under the United States Constitution by the Supreme Court of the United States in such manner that any person or concern required to pay contributions under this chapter might secure a similar decision, or that the tax imposed by Title IX of the Social Security Act, as amended, or any other federal tax against which contributions under this chapter may be credited has been amended or repealed by Congress or has been held unconstitutional by the Supreme Court of the United States, with the result that no portion of the contributions required by this chapter may be credited against such federal tax, the Governor shall publicly so proclaim and upon the date of such proclamation the provisions of this chapter requiring the payment of contributions and benefits shall be suspended. The secretary (and for the purposes of this section, the secretary shall remain or become the agency for carrying out the provisions hereof) shall thereupon forthwith requisition from the Unemployment Trust Fund all moneys therein standing to its credit and shall direct the Treasurer to deposit such moneys, together with any other moneys in the fund, as a special fund in any banks or public depositories in this state in which general funds of the state may be deposited. The secretary shall thereupon forthwith and within 60 days after receipt of such moneys, refund, without interest and in accordance with regulations prescribed by him, to each person or concern by whom contributions have been paid, his pro rata share of the total contributions paid under this chapter. After the expiration of said 60 days, the duties imposed by this section upon said secretary shall cease and determine and all powers conferred and duties imposed not then executed shall be conferred upon and executed by the Treasurer. Any interest or earnings of the fund shall be available to the secretary to pay for the costs of making such refunds. When the secretary shall have executed the duties prescribed in this section and performed such other acts as are incidental to the termination of his duties under this chapter, the Governor shall by proclamation declare that the provisions of this chapter shall cease to be operative.
