17-8-101. Appropriation and disbursement of money from treasury. (1) For purposes of complying with Article VIII, section 14, of the Montana constitution, money deposited in the general fund, the special revenue fund type (except money deposited in the treasury from nonstate and nonfederal sources restricted by law or by the terms of an agreement, such as a contract, trust agreement, or donation), and the capital projects fund type, with the exception of refunds authorized in subsection (4), may be paid out of the treasury only on appropriation made by law.
(2) Subject to the provisions of subsection (8), money deposited in the enterprise fund type, debt service fund type, internal service fund type, private purpose trust fund type, agency fund type, and state special revenue fund from nonstate and nonfederal sources restricted by law or by the terms of an agreement, such as a contract, trust agreement, or donation, may be paid out of the treasury:
(a) by appropriation; or
(b) under general laws, or contracts entered into in pursuance of law, permitting the disbursement if a subclass is established on the state financial system.
(3) The pension trust fund type is not considered a part of the state treasury for appropriation purposes. Money deposited in the pension trust fund type may be paid out of the treasury pursuant to general laws, trust agreement, or contract.
(4) Money paid into the state treasury through error or under circumstances such that the state is not legally entitled to retain it and a refund procedure is not otherwise provided by law may be refunded upon the submission of a verified claim approved by the department.
(5) Authority to expend appropriated money may be transferred from one state agency to another, provided that the original purpose of the appropriation is maintained.
(6) Fees and charges for services deposited in the internal service fund type must be based upon commensurate costs. The legislative auditor, during regularly scheduled audits of state agencies, shall audit and report on the reasonableness of internal service fund type fees and charges and on the fund equity balances.
(7) The creation of accounts in the enterprise fund or the internal service fund must be approved by the department, using conformity with generally accepted accounting principles as the primary approval criteria. The department shall report annually to the office of budget and program planning and the legislative fiscal analyst on the nature, status, and justification for all new accounts in the enterprise fund and the internal service fund. The report must be provided in an electronic format.
(8) Enterprise and internal service funds must be appropriated if they are used as a part of a program that is not an enterprise or internal service function and that otherwise requires an appropriation. An enterprise fund that is required by law to transfer money to the general fund or to any other appropriated fund is subject to appropriation. The payment of funds into an internal service fund must be authorized by law.
