There is no referendum in some democratic states like India, Japan, Netherlands, etc. Therefore, the referendum is not necessary condition for democracy. As Roskin argues that the Frances have taken an aversion to the referendum systems. Because the referendum systems in some states are very unique, and there is no universal rule to it. What we can only do is to induce some tendencies. Only a few political systems like Switzerland and some states in the USA. Adopt frequently the referendum to assist the public policies making. Most states only use it as the final appealed tool.
