N.J. Stat. Ann. § 18A:24-94

Nothing contained in this act shall be construed to relieve any school district or municipality of the obligation imposed on it by law to include in its annual budget amounts necessary to pay, in each year, the principal and interest maturing and becoming due on any qualified bonds issued by such school district or municipality; provided, however, that to the extent of the amounts withheld from State school aid payable to such school district or municipality and forwarded to the paying agent for such qualified bonds pursuant to section 8, such budgeted amounts, to the extent not needed to pay debt service on such qualified bonds, shall be applied to the payment of the operating expenses of such school district or municipality for such year; and provided, further, that in any year in which State school aid is not appropriated, such budgeted amounts shall be used to pay the debt service maturing and becoming due in such year on such qualified bonds of the school district or municipality.
