(1) If the Secretary of State refuses to place on the ballot any measure proposed by an initiative petition presented at least four months preceding the date of the election at which the proposed law or constitutional amendment is to be voted upon or a referendum petition presented within ninety days after the Legislature enacting the law to which the petition applies adjourns sine die or for a period longer than ninety days, any resident may apply, within ten days after such refusal, to the district court of Lancaster County for a writ of mandamus. If it is decided by the court that such petition is legally sufficient, the Secretary of State shall order the issue placed upon the ballot at the next general election.
(2) On a showing that an initiative or referendum petition is not legally sufficient, the court, on the application of any resident, may enjoin the Secretary of State and all other officers from certifying or printing on the official ballot for the next general election the ballot title and number of such measure. If a suit is filed against the Secretary of State seeking to enjoin him or her from placing the measure on the official ballot, the person who is the sponsor of record of the petition shall be a necessary party defendant in such suit.
(3) Such suits shall be advanced on the trial docket and heard and decided by the court as quickly as possible. Either party may appeal to the Court of Appeals within ten days after a decision is rendered. The appeal procedures described in the Administrative Procedure Act shall not apply to this section.
(4) The district court of Lancaster County shall have jurisdiction over all litigation arising under sections 32-1401 to 32-1416.
