N.C. Gen. Stat. § 159-50
When a unit of local government proposes to issue bonds that must be approved by a vote of the people, it shall first publish a notice of its intent to make application to the Commission for approval of the issue. The notice shall be published once not less than 10 days before the application is filed. The notice shall state (i) that the board intends to file an application with the Commission for approval of a bond issue, (ii) in brief and general terms the purpose of the proposed issue, (iii) the maximum amount of bonds to be issued, and (iv) that any citizen or taxpayer of the issuing unit may, within seven days after the date of the publication, file with the governing board and the Commission a statement of any objections he may have to the issue. The Commission may prescribe the form of the notice.
Any citizen or taxpayer of the issuing unit who objects to the proposed bond issue in whole or in part may, within seven days from the date of publication of the notice, file a written statement of his objections with the board and the Commission. The statement shall set forth each objection to the proposed bond issue and shall contain the name and address of the person filing it. The Commission shall consider the statement of objections along with the application and shall notify the objector and the board of its disposition of each objection.
Failure to comply with this section shall not affect the validity of any bonds otherwise issued in accordance with the law. This section shall not apply to bonds that need not be submitted to a vote of the people.
