Final answer:
An ex-officio member appointed by a council in a council-administrator system usually has membership due to their position and may or may not have voting rights, depending on the regulations of the body they serve on.
Step-by-step explanation:
An ex-officio member appointed by a council in a council-administrator system of government typically refers to someone who has membership by their office or position rather than by election or appointment to that specific role. Whether such members are voting members may vary based on the specific laws or regulations that establish the body they serve. In some governing bodies, all members including ex-officio ones have voting rights, while in others they may only participate in discussions without the right to vote.
This can also be true in other systems of government where appointments are made by executives; the appointed members might have varying degrees of legislative authority. An example is Bahrain's National Assembly, where members of the lower chamber are elected but the Consultative Council is appointed by the king. Another example is the election and appointment process in the council-elected executive system, where both council members and the executive are elected, but the executive has certain powers such as vetoing council actions.
