All existing special tax levies in all counties and school districts within the State may be reduced as deemed advisable by the local boards of trustees and the county boards of education, with the approval of the Senator and at least one half of the members of the House of Representatives of the county in which such reduction is made. But no tax levy for retiring bonds or other indebtedness of such school district shall be so reduced.
