If any school district other than a non-high school district shall for 1 year fail to maintain within the boundaries of the school district a recognized public school as required by law, such district shall become automatically dissolved and the property and territory of such district shall be disposed of in the manner provided for the disposal of territory and property in Section 7-11 of this Act. However, a school district shall not be dissolved where the State Board of Education and the regional superintendent of the region in which a district has legally authorized the building of a school and legally selected a school house site and has issued bonds for such building shall jointly find and certify that such building has been authorized, site selected and bonds issued.
If a district has its territory included within a petition to form a community unit district under Article 11E of this Code , that district may not be dissolved under this Section until the end of the school year in which all proceedings relating to formation of that community unit district are finally concluded, whether by disallowance of the petition, by referendum, by a final court decision or otherwise. Until such proceedings are finally concluded, the regional superintendent having jurisdiction of the district that is not maintaining a recognized school shall assign the pupils of that district to an adjoining school district, subject to the requirement that the district from which the pupils are so assigned shall pay tuition for such pupils to the district to which the pupils are assigned, in accordance with Section 10-20.12a of this Act or in such lesser amount as may be agreed to by the 2 districts.
However, until July 1, 1969 or one year after the entry of a final decision by a court of competent jurisdiction in the event of litigation with respect to any of the matters set forth in this Section, whichever is the later, notwithstanding the provisions of this Section, any protectorate high school district composed of contiguous and compact territory having not less than 2,000 inhabitants and which has an equalized assessed valuation of not less than $6,000,000, shall be and remain a protectorate high school district if a majority of the pupils attend a high school in a special charter district maintaining grades 1 through 12 and if during that period the voters of the district, by referendum to be ordered by the board, vote in favor of the proposition that such district maintain and operate a high school within such district, and also authorize the purchase of a school site, the building of a school building and the issuance of bonds for such purpose, which bonds are duly issued. The Board shall certify the proposition to the proper election authorities for submission, in accordance with the general election law.
The proposition to maintain and operate a high school within such district shall be in substantially the following form: -------------------------------------------------------------
Shall ......................
High School District Number ......, YES ........... County, Illinois, maintain and operate a high school ------------------------ within that High School District and for the benefit NO of the pupils residing therein? ------------------------------------------------------------- and is approved if a majority of the voters voting on the proposition is in favor thereof. The proposition of purchasing a school site, the building of a school building and the issuance of bonds for such purpose shall be submitted to the voters and may be voted upon at the same election that the proposition of maintaining and operating a high school within the district is submitted or at any regularly scheduled election subsequent thereto as may be ordered by the board. Thereupon, that protectorate high school district shall thereafter exist as a community high school district and possess and enjoy all of the powers, duties and authorities of a community high school district under Article 12 of this Act.
Throughout its existence as a protectorate district and until the legal voters residing in the district have determined to maintain and operate a high school within the district and have been authorized to purchase a school site, build a school building and to issue bonds for such purpose and which bonds are duly issued, or until the dissolution of the district as required by this Section, such protectorate district may use its funds to pay for the tuition and transportation of the pupils in such district that attend a high school in a special charter district maintaining grades 1 through 12. A protectorate high school district is defined to be a district which does not own or operate its own school buildings.
