Tenn. Code Ann. § 69-5-119

Upon the filing of the return of the engineer, the 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 this part, but if it does not appear to be expedient, or is not approved, the court is authorized to direct the engineer, or another engineer selected by it, to prepare another plan. If the court should deem the proposed improvement inexpedient or inadvisable, after an examination of the return of the engineer, or after a second or 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.
