The Maryville Daily Times says Judge Duggan will be sworn in on Sept. 1 and County Commission will appoint his replacement for General Sessions Court judge.
Read the Tennessee law governing appointments at this comment [1], particularly TCA 5-1-104 (b) (2) which says "If the vacancy occurs less than sixty (60) days before the August election but sixty (60) days or more before the November election, then nominees of political parties shall be selected by party convention and a successor elected in the November election."
Sept. 1, the day the vacancy will occur, is 64 days before the Nov. 4 election, right? Doesn't that mean there should be party conventions and a November election for the new General Sessions Judge?
