(b)
(1) If the petitioners and qualified electors shall show good and valid reason why the territory of the townships should not be governed by the order and shall, before the filing of the petition, give fifteen (15) days' notice, by publication, of their intention of filing and presenting the petition, and shall set forth in the notice their reasons why the township and petitioners should be exempt from the order adopting the act, then the court shall hear the petition, together with any remonstrance to it.
