Kan. Stat. § 12-1797
Any resident of or property owner within the city may appeal the action and decisions of the governing body of the city, or while acting as governing body of the district, including the creation of the district and the levying of the proposed taxes for the district, to the district court of the county in which any part of the district is located, within 30 days after the date upon which the ordinance creating the district becomes effective, but the action and decisions of the governing body are final and conclusive unless the court finds that the governing body exceeded its authority. No action may be brought questioning the regularity of the proceedings pertaining to the establishment of a district or the validity of the district, the propriety of the inclusion or exclusion of any property within or from the district, or the ability of the governing body of the district to levy taxes in accordance with the ordinance establishing the district, after 30 days from the date on which the ordinance creating the district becomes effective.
