In addition to the method provided in Section 10--9, when the drainage system of a subdistrict is of the same character, type or nature as any part of the drainage system of the main district, the commissioners of the subdistrict may petition the court to dissolve the subdistrict. Such petition must show: (a) the reasons for dissolving the subdistrict; (b) that there are no debts of the subdistrict outstanding or that there are sufficient funds on hand or available to satisfy such debts; (c) that no contract will be impaired by the dissolution of the subdistrict; and (d) that the drainage system of the subdistrict is of the same character, type or nature as some part of the drainage system of the main district. The petition shall be signed by the commissioners and be verified by at least one commissioner. Time for hearing of the petition shall be fixed and notice thereof given as provided by Section 10--6.
At the hearing the court shall determine whether there is good reason for dissolving the subdistrict and whether the allegations of the petition are true. If the court finds for the petitioners it shall order dissolution and the main district shall thereupon succeed to the drainage system, funds and property of the dissolved subdistrict and be responsible for the performance and fulfillment of the duties and obligations of the dissolved subdistrict.
When the drainage system of a minor subdistrict is of the same character, type or nature as any part of the drainage system of the subdistrict in which it is located, the minor subdistrict may be dissolved upon petition of the commissioners of the minor subdistrict in the same manner and subject to the same conditions as is provided by this section for the dissolution of a subdistrict. If a minor subdistrict is so dissolved the subdistrict in which it is located shall thereupon succeed to the drainage system, funds and property of the dissolved minor subdistrict and be responsible for the performance and fulfillment of the duties and obligations of the dissolved minor subdistrict.
