Refunding with bonds of another type

(1) Subject to the provisions of subsections (2), (3), and (4) of this section, nothing contained in this article shall be construed as authorizing a public body to issue any obligations constituting a debt or indebtedness for the purpose of refunding obligations which do not constitute debt or indebtedness. (2) Any revenue obligations of a public body may be refunded by the issuance of general obligation refunding bonds only if the public body would be authorized by law to issue general obligations for the purposes for which such revenue obligations were originally issued at the time of the issuance of said refunding bonds, whether or not the public body was so authorized at the time of the issuance of such revenue obligations. (3) If the issuance of general obligations for a particular purpose would be conditioned upon their approval by the qualified electors of the public body at an election, any general obligation refunding bonds proposed to be issued to refund revenue obligations originally issued for such purpose may be issued only if issuance of the refunding bonds has been approved at an election in the same manner. (4) If a debt limitation pertains to general obligation bonds or other general obligations of a public body issued for a particular purpose, then no general obligation bonds shall be issued to refund any revenue obligations issued for such purpose in any principal amount which would cause such debt limitation to be exceeded.
