The provisions of N.C. Gen. Stat. § 159-56 and the provisions of this Article related to the holding of a public hearing prior to the adoption of the bond order do not apply to refunding bonds issued by a unit of local government so long as the refunding bonds do not extend the final maturity of the debt or obligation to be refunded and so long as the aggregate debt service over the life of the refunding bonds is less than the aggregate debt service on the debt or obligation to be refunded. When the conditions of this section are satisfied, a unit of local government may introduce a bond order, adopt a bond order, and adopt a sale resolution with respect to refunding bonds in one or more meetings of the unit’s governing body.
