The Superintendent of Public Instruction may refuse to authorize the payment of any amount payable to any school district or intermediate unit for area technical schools for any school year, which the school district or intermediate unit shall at any time fail or refuse to pay to the members of its teaching and supervisory staffs the full amount of the minimum salaries and increments required by law. He may continue to withhold such requisitions until provision has been made by the school district or intermediate unit for the payment of such minimum salaries and increments.
