Said petition shall be addressed to the county court of the county in which the original petition for the formation of such sanitary district was filed and shall contain a definite description of the boundaries of such territory to be disconnected and recite as a fact, that there is no bonded indebtedness of such sanitary district incurred while such territory to be disconnected was a part of such sanitary district and that such territory to be disconnected is not, at the time of the filing of such petition, and will not be, either benefited or served by any work or improvement either then existing or then authorized by said sanitary district. Upon filing such petition in the office of the county clerk of the county in which the original petition for the formation of such sanitary district has been filed it shall be the duty of the county court of the county in which the original petition for the formation of such sanitary district was filed, to consider the boundaries of such territory and the facts upon which the petition is founded, and shall consider the limits and boundaries of such proposed territory, in the same manner as provided for locating, fixing and deciding of the limits and boundaries of the original sanitary district, as provided in section one of this article. If any part of the territory proposed to be disconnected is situated in another county or counties other than that county in which the original petition was filed, then it shall be the duty of the said county court of the county in which the original petition was filed to call to its assistance the county courts of counties in which portions of such territory proposed to be disconnected is situated; such county courts shall constitute themselves a board of commissioners, and after electing a presiding officer from among themselves, shall consider the boundaries of such territory and the facts upon which the petition is founded, and shall consider the limits and boundaries of such proposed territory to be disconnected, in the same manner as provided for locating, fixing and deciding of the limits and boundaries of the original sanitary district, as provided in section one of this article: Provided, however, That it shall be the duty of the county court or the board of commissioners to deny the prayer of the petition for the disconnecting of any territory from the original sanitary district, if the material allegations therein contained are not founded in fact.
Notice shall be given by the county court of the time and place, when and where all persons interested will be heard substantially as provided in section one of this article. The conduct of the hearing and the manner of conducting the subsequent election on the question whether such territory shall become disconnected and the issuance, reception, return and canvassing of the ballots shall be, as nearly as possible, in accordance with the provisions of section one of this article. The ballots for the election provided for in this section shall be substantially as follows, to wit:
___
/___/ For disconnection from sanitary district.
___
/___/ Against disconnection from sanitary district.
If a majority of the votes cast at such election shall be in favor of disconnection, and if the trustees of such sanitarydistrict shall, by ordinance, disconnect such territory, thereupon the county court of the county in which the original petition for the formation of such sanitary district was filed, shall enter an appropriate order in the records of the said county court and thereafter such territory shall henceforth be deemed disconnected from such sanitary district.
