Act Governing the Allocation of Government Revenues and Expenditures Article 38-1

When a government or legislative body at any level enacts, adopts, or amends laws or self-governing regulations, that would lead to a reduction in its revenues, it shall at the same time make sufficient plans for an alternative source of revenue; if it must increase its fiscal burden, it shall make sufficient plans in advance for related expenses, or, at the time of legislation, shall expressly provide for a corresponding source of revenue.
