Section 14.

When the Mayor refuses to sign an ordinance or resolution, or part thereof, and returns it to Council with his objections, the Council shall, after the expiration of not less than one week, proceed to reconsider it; and, if upon reconsideration, the ordinance or resolution, or part or item thereof, disapproved by the Mayor, be approved by the Council by a two-thirds vote of all members thereof; it shall take effect without the signature of the Mayor; provided, however, that no ordinance or resolution providing for the expenditure of more than Five Thousand ($5,000.00) Dollars, which has been disapproved by the Mayor, shall take effect after such reconsideration and approval by such two-thirds vote, unless it shall be submitted by Council to a referendum of the electors of the City at the next general election held throughout the City, more than sixty (60) days thereafter, and be approved by a majority of those voting thereon.
