Louisiana Revised Statutes Tit. 39, § 134. Legislative appropriation authority

A. No state agency shall make expenditures of any federal funds, whether such funds are advanced prior to expenditure or as reimbursement, unless such expenditures are made pursuant to specific appropriations by the legislature.

B. If the federal funds received are less than the amount of such funds appropriated by the legislature in accordance with this Part and for a specific purpose, the total appropriations of federal and state funds respectively allocated for such purpose shall be reduced in proportion to the amount of reduction in federal funds.

C. When the legislature is not in session, the Joint Legislative Committee on the Budget may approve the expenditure of available federal funds and appropriate necessary state matching funds. However, the delegated authority shall apply only when new or additional federal funds are available at a time which precludes their appropriation by the legislature in session.
