40.31  State Courts Administrator may apportion appropriation.--If the State Courts Administrator shall have reason to believe that the amount appropriated by the Legislature is insufficient to meet the expenses of jurors and witnesses during the remaining part of the state fiscal year, he or she may apportion the money in the treasury for that purpose among the several counties, basing such apportionment upon the amount expended for the payment of jurors and witnesses in each county during the prior fiscal year. In such case, each county shall be paid by warrant, issued by the Comptroller, only the amount so apportioned to each county, and, when the amount so apportioned is insufficient to pay in full all the jurors and witnesses during a quarterly fiscal period, the clerk of the court shall apportion the money received pro rata among the jurors and witnesses entitled to pay and shall give to each juror or witness a certificate of the amount of compensation still due, which certificate shall be held by the State Courts Administrator as other demands against the state.
