When a judgment is recovered against any township, an execution may not be issued upon the judgment, but the judgment, unless reversed or stayed on appeal, must be paid by the township treasurer upon demand and the delivery to the township treasurer of a certified copy of the docket of the judgment if there is sufficient money of the township in the treasurer’s hands not otherwise appropriated. If the treasurer, after having been ordered to pay such judgment by the board of township supervisors, fails to pay it when there is sufficient unappropriated money on hand with which to do so, the township treasurer personally is liable for the amount unless collection thereof afterwards is stayed upon appeal.
