Majority rule
Some people have criticized majority rule because it can lead to the tyranny of the majority which is not true democracy, where people who are the majority might vote for something that helps them but hurts the people in the minority or may even cause the negation of universal human rights, like Enabling Act. To prevent them, limit of constitutionalism and rule of law are established by German Constitution, as well as Council of Europe and European Union. This was also used in Greek voting.
