This Article argues that, as far as Hungary and Poland are concerned, the use of term “illiberal constitutionalism” is justified. It also claims that, without denying that other states could also be considered illiberal democracies, Hungary and Poland display unique and distinctive features. These features include populist politics, which lead to the relativization of the rule of law and democracy principles, and human rights protection, which captured the constitution and constitutionalism by constitutionalizing populist nationalism, constitutional identity, and created new patrionalism and clientelism. All these features are supported by the ideological indoctrination of political constitutionalism. In the course of this process, formal and informal constitutional amendments are used, and a formal sense of constitutional democracy is maintained. Overturning these illiberal democracies by constitutional and legal means, at this time, seems doubtful, if not impossible.
