Not to get into in about Miss laws .... but people should realize the OP link deals with a misdemeanor court. Originally the court would have been geographically limited to the area right around the state capital and courthouse and admin buildings, and there always has been a "capital police" force .... and it's grown and the city (Jackson) has grown smaller and poorer.

(And actually we may be getting better economically)
IF on the small chance anyone is interested in THE ACTUAL ISSUE AND what the state sup ct ruled the legislature may not to is .....
actual criminal and trial courts must have elected judges, but as has always been the case, the Sup Ct can, and does, appoint judges in emergencies, and the governor fills vacancies pending elections.

As to the OP link, it deals with the plaintiffs' efforts to get a federal court to weigh in, because they didn't like the actual win the plaintiffs got in the state sup ct.
