Any number of persons interested in contesting the enlargement or contraction of the boundaries of a municipality may join in one suit for the purpose of appealing to the district court from the ordinance adopted with reference thereto, and one bond by one of the litigants shall be sufficient if it otherwise complies with the laws. When more than one suit has been brought for either of said purposes, the district judge shall order them consolidated and tried as one suit.
