The board of finance, in addition to the specific powers and duties conferred upon it, shall advise and assist county boards of education and county superintendents in the planning and management of school finances to the end that the most effective program of public education be realized from the funds available for expenditure by the several counties.
In the exercise of its powers under this article, the board of finance shall not substitute its discretion and judgment for that of a county board of education with respect to the desirability or reasonability of a lawful school expenditure if the provisions of law and the orders of the board of finance are complied with by the county board. If, however, a county board fails or refuses to provide for the support of the standard school term, to adhere to the budget and the expenditure schedule, or to comply with other provisions of this article, the board of finance may require such action on the part of the county board, not in violation of law, as the board of finance may find to be best calculated to restore the financial affairs of the county board to a proper and lawful basis.
