Section 1. If authorized at an election held for such purpose, the governing body of Walker county may levy and collect a special county tax at a rate not exceeding one-half of one percent on the value of the taxable property within the county as assessed for state taxation, the proceeds of which shall be used exclusively for public school purposes; provided, however, that the governing body of Walker county shall not levy the special county property tax authorized by this amendment in addition to any tax authorized by a constitutional amendment proposed by the legislature at the same session of the legislature at which this amendment was proposed authorizing the governing body of each of the several counties in the state to levy an additional property tax for school purposes [amendment No. 202]. This tax shall be apportioned among the county and city school systems on a teacher unit basis in the manner that minimum program funds are distributed.

Section 2. An election shall be ordered by the county governing body to determine whether or not a special tax shall be levied for public school purposes as authorized herein upon the request of the county board of education, and the election shall be held and conducted in accordance with general laws providing for school tax elections pursuant to constitutional amendment III [3].
