Referandumlar are a form of direct democracy where citizens vote on specific issues or policies rather than for candidates. This process allows the electorate to express their opinions on important matters, such as constitutional amendments or changes in laws. In a referandum, the outcome is typically determined by a simple majority, meaning that more than half of the votes cast will decide the issue. This method empowers citizens to have a direct say in governance and can lead to significant changes in a country's legal or political landscape.
