'[The] scholarship is consistently thorough and lucid, and absolutely reliable' _European Public Law_ As reviews of the first edition attest, this book gives a unique critical and contextual insight into the Constitution of one the world's most powerful countries. Its first edition was published in 2011, when Dmitrii Medvedev was Russia's President. Since then there was a regime change in 2012 as Vladimir Putin returned to the presidency, and, significantly, dramatic shifts in constitutionality as Russia pursues a 'return to traditional values'. The book explores the Constitution's evolution over its nearly 30 years' existence, including the significant amendments of 2020. This second edition situates these important changes in the context of Russia's historical and legal development, as Putin continues to dominate the political scene. It also looks at broader constitutional questions on the interrelation between the main State agencies, the role of the courts, human rights and their enforcement.
