Ga. Const. art. VIII, § 5, para. 1

Authority is granted to county and area boards of education to establish and maintain public schools within their limits; provided, however, that the authority provided for in this paragraph shall not diminish any authority of the General Assembly otherwise granted under this article, including the authority to establish special schools as provided for in Article VIII, Section V, Paragraph VII. Existing county and independent school systems shall be continued, except that the General Assembly may provide by law for the consolidation of two or more county school systems, independent school systems, portions thereof, or any combination thereof into a single county or area school system under the control and management of a county or area board of education, under such terms and conditions as the General Assembly may prescribe; but no such consolidation shall become effective until approved by a majority of the qualified voters voting thereon in each separate school system proposed to be consolidated. No independent school system shall hereafter be established.
