Tennessee Code Title 54. Highways, Bridges and Ferries § 54-12-127

(a) Upon the filing of the return of the engineer, the monthly county court shall examine the return, and if the plan seems to be expedient and meets the approval of the court, it shall order the county clerk to cause notice to be given as provided in §§ 54-12-128 -- 54-12-131; but if it does not appear to be expedient, and it is not approved, the court is authorized to direct the engineer or another selected by it to prepare another plan.

(b) If the court deems the proposed improvement inexpedient or inadvisable after an examination of the return of the engineer or after a second further return, it may dismiss the petition and proceedings, and, in that event, it shall adjudge all costs and expenses incurred against the petitioners and the sureties on the bond.
