Constitutionalism under Stress reflects on comparative constitutionalism in Central and Eastern Europe through the work of eminent constitutional scholar Wojciech Sadurski. The book examines the current decline of liberal democracies and populist challenges to the rule of law in the region - events that Sadurski predicted early on in his writings about Jörg Haider affair in Austria and the introduction of Article 7 TEU by the Amsterdam Treaty.Sadurski's work has chronicled the transition from concern for the most basic of human rights under authoritarian rule to the challenges of democratic governance. The compelling rights discourse of an earlier period gave way to claims of abuse of majoritarian prerogatives as the hopes of liberal democracy encountered the power of illiberalism. The theoretical responses offered for the preservation of liberal democracy, in light of the current turbulence regarding the rule of law in the region, produces a far reaching and effective reference tool on matters of constitutional capture and illiberal democracy.
