Moneys shall be requisitioned from this State's account in the Unemployment Trust Fund solely for the payment of benefits and/or self-employment assistance allowances and in accordance with regulations prescribed by the Department. The Department shall from time to time requisition from the Unemployment Trust Fund such amounts, not exceeding the amounts standing to this State's account therein, as it deems necessary for the payment of benefits and/or self-employment assistance allowances for a reasonable future period. Upon receipt thereof the State Treasurer shall deposit such moneys in the benefit account and shall issue warrants for the payment of benefits and/or self-employment assistance allowances solely from such benefit account. Expenditures of such moneys in the benefit account and refunds from the clearing account shall not be subject to any provisions of law requiring specific appropriations or other formal release by state officers of money in their custody. All warrants issued by the State Treasurer for the payment of benefits and/or self-employment assistance allowances and refunds shall bear the signature of the State Treasurer and the countersignature of the Department or its duly authorized agent for that purpose. Any balance of moneys requisitioned from the Unemployment Trust Fund which remains unclaimed or unpaid in the benefit account after the expiration of the period for which such sums were requisitioned shall either be deducted from estimates for and may be utilized for the payment of benefits and/or self-employment assistance allowances during succeeding periods, or, at the discretion of the Department, shall be redeposited with the Secretary of the Treasury of the United States to the credit of this State's account in the Unemployment Trust Fund, as provided in § 3162 of this title.
