Tennessee Code Title 54. Highways, Bridges and Ferries § 54-12-215

If, after the district has been created and the commissioners for the assessment of benefits have made their report, the report has been acted upon and confirmed by the monthly county court, the time for an appeal from the confirmation has elapsed and no appeal has been taken, and it appears to the court that the costs and expenses of the proceedings up to that state of the proceedings have not been otherwise paid, the court shall have the power to make a special assessment upon all the lands within the district, for an amount sufficient to pay the costs and expenses, including the expenses of collecting the special assessment.
