Wyo. Stat. § 37-7-127
The court, may, upon the petition of the commissioners authorize them to refund any lawful indebtedness of the district now existing or which may hereafter be incurred by taking up and canceling all or any part of its outstanding notes and bonds, as fast as they come due or before, if the holders thereof will surrender the same and issue in lieu thereof new notes or bonds of such district, payable in such longer time as the court shall deem proper, in an amount sufficient to retire notes and bonds of the district then outstanding and the unpaid accrued interest thereon, together with such an amount as the commissioners of such district may deem necessary to provide for possible future defaults and delinquencies in the payment of assessments, and bearing interest not exceeding seven percent (7%) per annum. For the purpose of providing funds to pay such refunding bonds with interest thereon, the commissioners may levy assessments against the land in such district, but not in excess of the benefits assessed. In the alternative the commissioners may, if they deem it advisable, issue said refunding bonds in an amount sufficient only to retire all notes and bonds of the district then outstanding and the unpaid accrued interest thereon, and delinquencies in the payment of assessments levied, from year to year, assessments against the land in such district for such purposes, but not in excess of the benefits assessed against the same.
