Each political subdivision of the State shall file with the Secretary of Finance a notice of intent to issue its general obligations or revenue-supported debt at least 14 days prior to the anticipated sale date of any such obligations. The notice shall describe briefly the proposed principal amount of obligations to be sold, the proposed sale date and the purpose of the issue, and shall be signed by the chief fiscal officer of the political subdivision submitting the notice. Failure to submit such notice or any change in the details of the issue from those set forth in such notice shall not invalidate the issuance of any such obligations.
