Okla. Stat. tit. 68 § 3008
The county excise board may require the attendance of the District Attorney at any of its sessions when passing upon the validity or invalidity of items of appropriation; or it may request his opinion in writing as to any such item. Said board is hereby empowered to require such further detail as to any item of any estimate as it deems necessary and proper for such determination, and it may place such restrictions thereon as will limit the use thereof to purposes authorized by law; but such further detail and such restrictions shall not enlarge upon the number of accounts in the bookkeeping systems prescribed and kept as provided by law. However, such further detail and any restrictions imposed thereon shall be disclosed by statements attached to the original copy of such budget filed with the county clerk, and to the duplicate copy of such budget filed with the State Auditor and Inspector. If such excise board desires assistance for the purpose of inspecting and correcting financial statements and accounts, and inspection of levies, it may invoke those provisions of law providing such assistance (74 O.S. 1961, Section 212), provided there shall have been made an appropriation for county audit and an assignment to such county for such purpose.
