Any municipality, as defined in § 7-369, which issues bonds, notes or other obligations pursuant to the provisions of the general statutes or any special act may designate the manner in which such bonds, notes or other obligations shall be issued and the person or persons by whom they shall be signed and shall provide for keeping a record of the same or shall authorize any official or municipal body to make such designations and to take such actions. Any such municipality may authorize its selectmen or board of finance or other officers or board to determine the rate or rates of interest or discount which such bonds, notes or other obligations shall bear and the time or times at which interest on such bonds, notes or other obligations shall be payable, or to establish the method or manner for making such determinations, and to determine all other terms, details and particulars pertaining to the issuance and sale of such bonds, notes or other obligations, including the time or times for payment of principal, subject to the provisions of the general statutes concerning the time or times at which bonds, notes or other obligations shall mature. Any bonds, notes or other obligations issued pursuant to the general statutes or any special act may be sold at public sale on sealed proposals or by negotiation in such manner, at such price or prices, at such time or times and on such other terms and conditions as the municipality issuing such bonds, notes or other obligations, or the officers or board delegated the authority to issue such bonds, notes or other obligations, may determine. The provisions of this section shall not affect the authority of the selectmen of any town to issue bonds where so authorized by special act.
