SEC. 7.06. ENFORCEMENT OF THE BUDGET.
   The City Council shall enforce strictly the provision of the budget. The Council shall not authorize any payment of the incurring of any obligation by the City unless an appropriation has been made for the same and there is a sufficient unexpended balance left after deducting the total past expenditures and encumbrances against the appropriation. No officer or employee of the City shall place any order or make any purchase for a purpose not authorized in the budget resolution or authorized in advance except by an ordinance drafted to specifically define and empower emergency response activities.
   Any obligation incurred by any person in the employ of the City for any purpose not authorized in the budget resolution or for any amount exceeding an appropriation shall be a personal obligation upon the person incurring the obligation.
   No check shall be issued or transfer made to any account other than one owned by the City until the claim to which it relates has been supported by an itemized bill, payroll, or time-sheet or other document approved and signed by the responsible City officer who vouches for its correctness and reasonableness.
