(a) All city contracts calling for or requiring the expenditure or payment of an amount required by state law to be submitted to competitive bids must be submitted to competitive bids in accordance with state law. The city shall have the right to reject any and all bids. Any contract submitted to competitive bids shall be let to the lowest responsible bidder, quality considered.
(b) The City Council shall by ordinance establish rules by which a contract may be signed by the city manager without City Council approval; provided, however, that a contract which is required to be bid and which is let to other than the lowest bidder shall be first approved by the City Council. All contracts other than those prescribed by ordinance which allow the city manager to sign same without City Council approval shall be approved by the City Council and shall not be binding upon the city unless or until so approved.
The provisions of this section, as amended, shall take effect on January 1, 1984.
