A referendum is a direct vote in which an electorate can either approve or reject a proposed change in law or policy. This process empowers citizens by allowing them to directly influence significant political decisions, thus enhancing democratic participation. Referendums can address various issues, ranging from constitutional amendments to particular governmental policies. They often serve as a tool for gauging public opinion on divisive topics, promoting accountability among elected officials. By involving citizens directly in decision-making, referendums strengthen the legitimacy of the political process.
