Q Is there any prohibition in state or federal law from an individual serving simultaneously as justice court judge and as an alderwoman?

A Yes. A person may not serve simultaneously as an alderwoman, which is in the legislative branch and as a justice court judge which is in the judicial branch. Since both offices exercise core powers, simultaneously serving in both would violate the separation of powers doctrine set forth in Miss. Const. Art. I and II.
