Colorado Constitution of 1876 Art. IX, § 3. School fund inviolate

The public school fund of the state shall, except as provided in this article IX, forever remain inviolate and intact and the interest and other income thereon, only, shall be expended in the maintenance of the schools of the state, and shall be distributed amongst the several counties and school districts of the state, in such manner as may be prescribed by law. No part of this fund, principal, interest, or other income shall ever be transferred to any other fund, or used or appropriated, except as provided in this article IX. The state treasurer shall be the custodian of this fund, and the same shall be securely and profitably invested as may be by law directed. The state shall supply all losses thereof that may in any manner occur. In order to assist public schools in the state in providing necessary buildings, land, and equipment, the general assembly may adopt laws establishing the terms and conditions upon which the state treasurer may (1) invest the fund in bonds of school districts, (2) use all or any portion of the fund or the interest or other income thereon to guaranty bonds issued by school districts, or (3) make loans to school districts. Distributions of interest and other income for the benefit of public schools provided for in this article IX shall be in addition to and not a substitute for other moneys appropriated by the general assembly for such purposes.
