Colorado Revised Statutes Title 11. Financial Institutions § 11-54-107. Payment of refunding public securities

Refunding public securities may be made payable from any revenues derived from any utility, system, project, or other source which might be legally pledged for the payment of the public securities being refunded at the time of the refunding or at the time of the issuance of the public securities being refunded, as the governing body of the issuer may determine, notwithstanding the pledge of such revenues for the payment of the outstanding public securities being refunded is thereby modified;  but there shall not be pledged for the payment of the refunding public securities any revenues which might not have been lawfully pledged for the payment of the public securities being refunded because of limitations in any question authorizing their issuance, unless the refunding public securities are similarly authorized at an election by the majority required by law for the issuance of the public securities being refunded.
