Louisiana Revised Statutes Tit. 38, § 1757. Contests and objections

Within thirty days from the date of the first publication any owner of property within the limits of the gravity drainage district or sub-drainage district may appeal to the courts for the purpose of contesting the action of the police jury or police juries, or urging any objection to the inclusion of his lands in the gravity drainage district or gravity sub-drainage district. After this time the action of the police jury or police juries shall be absolutely incontestable for any cause whatsoever, and it shall be conclusively presumed that the gravity drainage or sub-drainage district is regularly and legally created and that each and every acre of land in the gravity drainage or sub-drainage district is the character of land that should be included therein. No court shall be vested with jurisdiction to entertain any cause which calls in question the validity or regularity of the action of the said police jury in creating or re-organizing the gravity drainage or sub-drainage district, or raises the question of whether the lands located therein should have been included, drain naturally or by gravity, or will be benefited by gravity drainage works. Nothing contained in this section shall be construed as requiring the board of drainage commissions of any gravity drainage or sub-drainage district to await the expiration of the thirty days limitation herein provided for, before proceeding to organize and do and perform all of the acts or things authorized to be done and performed by them under the provisions of this Part.
