Tenn. Code § 69-5-602
If there is a vacancy in the office of the director appointed as mentioned in § 69-5-601, because of death, resignation, or other reason, the county legislative body shall appoint another director of like qualifications to fill such vacancy until the end of the two-year term, and for sufficient reason the county legislative body may remove a director so appointed, but not until such director has had at least five (5) days' notice of the time of the hearing, and of the grounds on which the director should be removed, as alleged, and the director shall thus be entitled to be heard and to introduce proof upon the issue as to whether the director should be so removed as a director. If, on the hearing, the decision of the county legislative body is that the director be removed, the director may appeal from the decision, on giving proper cost bond, to the circuit court of the county, where the matter shall be heard anew and such judgment given as that court deems just and proper. If a director is removed, the county legislative body shall appoint another to serve the remainder of the two-year term, having like qualifications as to ownership of lands, as provided in this part.
