Can a weighted voting system have dummy voters without a dictator?

Yes, a weighted voting system can have dummy voters without having a dictator. Dummy voters are those whose votes do not affect the outcome of a decision, but this does not imply the presence of a dictator, who is a voter whose preferences alone determine the outcome. In a weighted voting system, it’s possible for certain voters to hold weights that do not contribute to achieving the necessary quota for decision-making, while still allowing other voters to collectively influence the outcome. Thus, dummy voters can exist independently of a single dominant voter.
