At the hearing the court shall first determine whether the districts are contiguous and whether the petition is signed by at least one-tenth of the adult owners in each district who own at least one-fifth of the land in each district. If the districts are not contiguous or if the petition is not so signed, the petition shall be dismissed.
If the districts are contiguous and the petition is so signed but it is not signed by a majority of the adult owners in each district owning more than one-third of the land in each district, or by more than one-third of the adult owners in each district owning a major portion of the land in each district, the court shall then order the question of consolidation submitted to the adult owners of land in each district at a special election to be held in each district. The court shall fix the day upon which the election shall be held which shall be the same day in each district and which shall not be less than 30 nor more than 60 days from the day the order is entered. The court, at the time of calling the election, shall also designate the polling place or places in each district and designate the hours at which the polling places will open and close. Upon calling the election the court shall continue the cause to a day certain, which day shall be not less than 7 nor more than 14 days following the day fixed for the election.
The clerk of each district shall give notice of the election by publishing notice thereof in the manner and for the length of time provided in Section 4--22 in the case of a hearing on a petition. The ballots cast at the election shall be in substantially the following form:
------------------------------------------------------------------------ Shall (name of district in which election is being held), be merged with (name of other district or districts) to organize (name of consolidated district) ------------------------------------------------------------------------ Yes No ------------------------------------------------------------------------
The reverse side of the ballot shall show the official nature of the ballot by the certificate of the clerk, and it shall be the duty of the clerk to cause the ballots to be prepared. The commissioners of each district shall serve as the judges of the election unless the court shall designate other judges at the time of calling the election. The ballots and the results shall be returned to the clerk of the district within 48 hours after the election and he shall, within 5 days thereafter, report the results of the election to the court. The cost of the election in each district shall be borne by that district. If, in each district, a majority of the owners voting on the question shall favor consolidation and if the court thereupon finds that such consolidation will be beneficial to the major portion of the land in each district, the court shall order the merger of the districts into the consolidated district.
If, at the hearing the court determines that the districts are contiguous and that the petition is signed by a majority of the adult owners in each district owning more than one-third of the land in each district or by more than one-third of the adult owners in each district owning a major portion of the land in each district, then no election shall be necessary and if the court further finds that such consolidation will be beneficial to a major portion of the lands in each district, the court shall order the merger of the districts into the consolidated district.
The affidavit of one or more credible persons may be taken as prima facie evidence as to the proportion of the owners signing the petition and of the proportion of the area owned by them.
