§1067. Amount of contracts to be charged against appropriations.

(a) General rule.--A contract involving appropriation of money shall designate the item of appropriation on which it is founded, and the estimated amount of the expenditure which shall be charged against the item, and certified by the borough controller on the contract, before it shall take effect as a contract. Payment required by the contract shall be made from the fund appropriated.

(b) Liability for excess.--If the controller certifies a contract in excess of the appropriation made, the borough shall not be liable for the excess, but the controller and the controller's sureties shall be liable for the same, which may be recovered in an action at law by the aggrieved contracting party.

(c) Certification by controller.--The controller shall certify contracts for the payment of which sufficient appropriations have been made.
