Before issuing any revenue bonds hereunder, the governing body of any municipality shall adopt a resolution declaring its intention to so issue, stating the amount of bonds proposed to be issued, the purpose for which the bonds are to be issued, and the date upon which the governing body proposes to direct the issuance of such bonds. Such resolution shall be published once a week for at least three (3) consecutive weeks in at least one (1) newspaper published in the county in which such municipality is located. The first publication of such resolution shall be made not less than twenty-one (21) days prior to the date fixed in such resolution for the issuance of the bonds and the last publication shall be made not more than seven (7) days prior to such date. If no newspaper be published in such county, then such notice shall be given by publishing the resolution for the required time in some newspaper having a general circulation in such county, and, in addition, by posting a copy of such resolution for at least twenty-one (21) days next preceding the date fixed therein at three (3) public places in such county. If twenty percent (20%) or fifteen hundred (1500), whichever is less, of the qualified electors of the municipality shall file a written protest against the issuance of such bonds on or before the date specified in such resolution, then an election on the question of the issuance of such bonds shall be called and held as herein provided. If no such protest be filed, then such bonds may be issued without an election at any time within a period of two (2) years after the date specified in the above-mentioned resolution. However, the governing body of such municipality, in its discretion, may nevertheless call an election on the question of the issuance of the bonds, in which event it shall not be necessary to publish the resolution declaring its intention to issue bonds as herein provided.
