105 ILCS 5/17-15: Failure of collector to pay.

If any collector fails to pay the taxes or any part thereof, the school treasurer or other authorized person may proceed against him and his sureties in a civil action upon his official bond in any court of competent jurisdiction. The collector so in default shall pay 12% of the amount due to be assessed as damages, which shall be included in the judgment rendered against him. If he can show that any part of the taxes could not be collected by law, he shall not be liable for such taxes until he has collected, or may be able to collect them.
