A plebiscite is a direct vote in which an entire electorate is invited to vote on a particular proposal, typically related to constitutional changes or significant policies. Unlike a referendum, which generally seeks public approval of legislation passed by a legislative body, a plebiscite often involves issues not yet legislated. While both are forms of direct democracy, the main difference lies in their contexts; a plebiscite addresses broader questions and can reflect public opinion without being tied to existing laws.
