Tenn. Code Ann. § 24-2-107

Rule 45 of the Rules of Civil Procedure shall govern when a clerk or other authorized officer is required to issue a subpoena in a civil case in circuit court and the consequences of a person's refusal to appear, testify or produce evidence when subpoenaed pursuant to such rule. If any local rule of court conflicts with Rule 45, Rule 45 shall prevail, and the clerk or other authorized officer shall issue subpoenas and the judge shall punish the refusal to respond to subpoenas in accordance with such rule.
