Or. Const. art. XI-K, § 4

The State of Oregon may issue bonds if and as necessary to provide funding to satisfy the state's guaranty obligations undertaken pursuant to this Article. In addition, notwithstanding anything to the contrary in Article VIII of this Constitution, the state may borrow available moneys from the Common School Fund if such borrowing is reasonably necessary to satisfy the state's guaranty obligations undertaken pursuant to this Article. The State of Oregon also may issue bonds if and as necessary to provide funding to repay the borrowed moneys, and any interest thereon, to the Common School Fund. The bonds shall be payable from any moneys reimbursed to the state under section 3 of this Article, from any moneys recoverable from the school district, the education service district or the community college district that incurred the bonded indebtedness with respect to which any payment under the state's guaranty is made, any other funds available for these purposes and, if necessary, from state ad valorem taxes.
