The Tennessee Rules of Criminal Procedure states that “Any person arrested-except upon a capias pursuant to an indictment or presentment- shall be taken without necessary delay before the nearest appropriate magistrate of: the county from which the arrest warrant issued; or the county in which the alleged offense occurred if the arrest is made without a warrant…” This means that typically you will be brought before a judge within 24 hours. There are a few exceptions, such as if you are arrested over the weekend or on a holiday you may have to wait until Monday or until the courts reopen before you see a judge.
