VII of the State Constitution and such election shall be called within 60 days after the governing body of such taxing district shall receive a petition requesting the same signed by a number of owners of freeholds not wholly exempt from taxation equal to 25 percent of the qualified electors who are owners of such freeholds residing in such district and by the holder or holders of a majority in amount of the bonds or outstanding indebtedness to be refunded, but nothing in this chapter shall preclude the issuance of refunding bonds under this chapter when such refunding bonds are issued and are provided to be supported by the proceeds of special assessments of the same kind and character as were provided for the issue which is refunded.s. 22, ch. 15772, 1931; CGL 1936 Supp. 2383(22); s. 15, ch. 69-216.
