S.D. Codified Laws § 13-19-8.1
For the purpose of § 13-19-8, the outstanding indebtedness of any school district created by reorganization under chapter 13-6, shall include the principal and accrued interest thereon of all preexisting bonded indebtedness outstanding against any portion of a former school district included in the boundaries of the school district created by reorganization, as ascertained in the adjustment of property, assets, debts, and liabilities made by the board of county commissioners upon the reorganization. All such preexisting bonded indebtedness, and all bonds authorized and issued in accordance with law by the new school district entity created by reorganization, shall be and remain valid and binding general obligations of said districts, provided that the net bonded indebtedness thereof does not exceed the constitutional debt limitation. If the tax levy upon any former school district area for the payment of such preexisting bonded indebtedness, plus the tax levy on such area required for the payment of bonds of the new school district entity created by reorganization, should at any time be held by any court of competent jurisdiction to impose upon such area a debt or liability in excess of the constitutional limit, not offset by the benefits assured to such area by the terms of the adjustment of property, assets, debts, and liabilities theretofore made by the board of county commissioners, the validity of said bonds of such new school district as general obligation bonds shall not in any wise be impaired thereby; but the board of county commissioners shall without delay effect such readjustment of property, assets, debts, and liabilities as may be required, and the court shall have jurisdiction to order such readjustment and to determine the true and correct amount of each item therein.
