It shall be the duty of the district attorney to examine such petition carefully, and if it appears to him, or if he has any reason to believe, that such petition is defective, insufficient, or untrue, or if it is his opinion that the obligations in question have not been properly authorized or would be in violation of law, that the tax or other means provided for their payment would not be valid or that any pledge or other covenant or provision for the benefit of said obligations would not be valid, then he shall make such defense thereto as to him shall seem proper.

By the publication of such notice, all taxpayers and citizens of such unit shall become parties defendant to said proceedings, and the court shall have jurisdiction of them the same as if each of them were named individually as a party defendant in said petition and personally served with process.
