SECTION 6.07. LIMITATION ON RATE OF TAXATION.
   The Council shall not have the power to levy annually upon the tax lists or duplicates of property listed and assessed for taxation according to value, without a vote of the people, taxes for current expenses of the Municipal corporation of more than four and two-tenths mills, including those levies required by law for police and fire pensions, provided that said four and two-tenths mills shall be reduced in each year by that number of mills, including fractional parts thereof, which are levied in the respective year by the City within the ten mill limitation imposed by Article XII, Section 2, of the Ohio Constitution, for the purpose of paying interest on, and principal of, obligations issued without a vote of the people.
   The limitation of this Charter upon the power of Council to levy taxes shall not operate as a limitation upon the power of Council to levy taxes upon such other subjects and for such other purposes as may be lawful under the Constitution and laws of Ohio, nor shall the authority of Council to submit additional levies to a vote of the people under the authority of the Constitution or laws of the State of Ohio be deemed impaired or abridged by reason of any provision of this Charter.
