The Supreme Court of Nebraska reversed the decision of the district court in a case challenging the constitutionality of a statute governing the calculation of taxes to fund education for students in non-high school districts. The Supreme Court found that: (1) the district court order finding the statute unconstitutional was a final, appealable order; (2) the case could not proceed as a class action due to conflicts of interest among class members; and (3) the plaintiffs were estopped from challenging the constitutionality of the statute since they utilized the statutory process for appealing the tax levy. The case was remanded to the district court for further proceedings.
