The difference between a plebiscite and a referendum lies primarily in their purpose and usage in a democratic process. A plebiscite is a direct vote by the electorate on a specific question, often related to issues like constitutional amendments or significant policy changes. It does not necessarily require legislative action. Conversely, a referendum typically involves a legislative proposal being put to a direct vote to approve or reject a measure, serving as a form of direct democracy. While both seek public opinion, a referendum is generally part of a legislative process, whereas a plebiscite may stand alone.
