§ 37-13-118 — Adoption of the assessment resolution; civil action; statute of limitations

After the public hearing has been concluded and all corrections
made to the assessment list, the governing body shall proceed to
adopt the assessment resolution. The resolution and supporting
findings shall be conclusive against all persons unless an
action contesting the validity of this law or the acts
contemplated by this law shall be commenced in a court of
competent jurisdiction within thirty (30) days after the
adoption of the assessment ordinance. Thereafter, any such
action shall be barred and the organization of the district, the
assessment levied pursuant thereto, or any other act authorized
by this statute shall not be directly or collaterally questioned
in any suit, action, or proceeding. The statute of limitations
provided herein shall be an additional limitation to and
supplement any requirements of the Wyoming Administrative
Procedure Act or any rules issued thereunder. If the contest is
unsuccessful, the court may order the plaintiff to pay the costs
thereof, and, in its discretion, may require a bond in a
sufficient amount to cover the costs at the commencement of the
action. The burden of proof to show that the special assessment
or part thereof is invalid, inequitable or unjust shall rest
upon the party who brings the suit.
