Idaho Code § 43-2204
Except in the instance of bonds issued and sold to refund other bonds for which a confirmation proceeding pursuant to this section has already been held, the board shall file a petition in the district court of the county in which the office of the board is located, pursuant to the provisions of sections 43-406 through 43-408, Idaho Code, prior to the sale and issuance of any bonds under this chapter. Whenever any district which is required to file a petition hereunder has or proposes to enter into a contract or contracts with one or more irrigation districts pursuant to section 43-2201(D)(2), Idaho Code, and such other irrigation district or districts is authorized or required to bring a confirmation proceeding or proceedings pursuant to the provisions of section 43-406 or of section 43-1808, Idaho Code, with respect to such contracts or the levy of assessments or the apportionment of costs, the boards of each of such other irrigation districts shall join in the filing of such petition, and the district court in which such petition is filed shall have jurisdiction to hear the petition and to grant the relief prayed for therein. Each such petition shall pray for a judicial examination and determination of any power conferred hereby or by any amendment hereto or of any assessment levied or of any apportionment of costs or of any act, proceeding or contract of the district or districts, whether or not said contracts shall have been executed, including proposed contracts for the reconstruction, rehabilitation, replacement and improvement of any such dam and other related structures and works and appurtenances, falling water contracts pursuant to section 43-2201(D)(4), Idaho Code, contracts with other irrigation districts pursuant to section 43-2201(D)(2), Idaho Code, and contracts with other public and private persons, firms, corporations and associations pursuant to section 43-2201(D)(3), Idaho Code. Such petition shall set forth the facts whereon the validity of such powers, assessments, apportionments, acts, proceedings or contracts is founded. Notice of the filing of said petition shall be given by the clerk of the court by mailing, and by publication in at least one (1) newspaper published and of general circulation within the boundaries of each irrigation district joining in the petition, or if no newspaper is so published within any district, then in a newspaper published in the same county in which any part of such irrigation district is located which is of general circulation in such irrigation district, pursuant to and in accordance with the requirements of section 43-407, Idaho Code, under the seal thereof, stating in brief outline the contents of the petition and showing where a full copy of any contract or contracts, therein mentioned, may be examined.
Any owner of property in any district joining in the petition or any other person interested in the contracts or proposed contracts may appear and answer said petition at any time prior to the date fixed for said hearing or within such further time as may be allowed by the court; and the petition shall be taken as confessed by all persons who fail so to appear. The said petition and notice shall be sufficient to give the court jurisdiction and, upon hearing, the court shall examine into and determine all matters and things affecting the question submitted, shall examine all of the proceedings of all of the irrigation districts as set forth in the petition, shall hear all objections either filed in said proceeding or brought up from the hearings before any of the boards, shall correct all errors in the assessments and apportionments of costs, shall ratify, approve and confirm all apportionments of costs and assessments levied, shall make such findings with reference thereto and render a judgment and decree thereon approving and confirming all of the powers, assessments, apportionments, acts, proceedings and contracts of each of the irrigation districts as set forth in the petition as the case warrants. Costs may be divided or apportioned among the contesting parties in the discretion of the trial court. Review of the judgment of the court may be had as in other similar cases, except that such review must be applied for within thirty (30) days after the time of the rendition of such judgment, or within such additional time as may be allowed by the court within thirty (30) days. The Idaho Rules of Civil Procedure shall govern in matters of pleading and practice where not otherwise specified herein. The court shall disregard any error, irregularity or omission which does not affect the substantial rights of the parties. Except as provided herein, the provisions of sections 43-406 through 43-408, Idaho Code, shall apply to the proceeding herein authorized.
Except as expressly provided in this section, the provisions of sections 43-406 through 43-408, Idaho Code, shall be inapplicable to refunding bonds issued under this chapter.
