The resolution authorizing the bonds provided for in section fourteen of this article may direct that they contain the following recital:
"It is certified that this bond is authorized by and is issued in conformity with the requirements of the Constitution and Statutes of the State of West Virginia."
The recital, when the bonds have been endorsed by the Attorney General as provided in section twenty-eight of this article, are considered an authorized declaration by the governing body of the political division and to import that there is constitutional and statutory authority for incurring the debts and issuing the bonds; that all the proceedings therefor are regular; that all the acts, conditions and things required to exist, happen and be performed precedent to and in the issuance of the bonds have existed, happened and been performed in due time, form and manner as required by law; that the amount of the bond and the issue of which it forms a part, together with all other indebtedness, does not exceed any limit or limits prescribed by the constitution or statutes of this state; and that all questions connected with incurring the debt and issuing the bonds have been first submitted to a vote of the people and have received the required amount of all the votes, pursuant to section four of this article, cast for and against the same at an election regularly called and held for the purpose after notice published and posted in the manner required by law. If any bond be issued containing the recital, and also containing the endorsement of the Attorney General as aforesaid, it shall be conclusively presumed that the recital, construed according to the import hereby declared, is true and neither the political division nor any taxpayer thereof shall be permitted to question the validity or regularity of the obligation in any court or in any action or proceeding.
