A referendum functions in a democratic political system as a direct vote in which an electorate decides on a specific policy or constitutional amendment. This process allows citizens to express their opinions on critical issues, fostering political engagement and participation. Referendums can address a range of topics, such as changing laws, social reforms, or governmental structures, providing a mechanism for public decision-making. By allowing voters to directly influence policy, referendums serve as a tool for accountability, reflecting the will of the people and enhancing democratic legitimacy.
